Embodied cognition is the theory that many features of cognition, whether human or otherwise, are shaped by aspects of the entire body of the organism. The features of cognition include high level mental constructs (such as concepts and categories) and performance on various cognitive tasks (such as reasoning or judgment). The aspects of the body include the motor system, the perceptual system, bodily interactions with the environment (situatedness) and the assumptions about the world that are built into the structure of the organism.
Cognition is "the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses many aspects of intellectual functions and processes such as attention, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and "computation", problem solving and decision making, comprehension and production of language. Cognitive processes use existing knowledge and generate new knowledge.
Concepts are defined as abstract ideas or general notions that occur in the mind, in speech, or in thought. They are understood to be the fundamental building blocks of thoughts and beliefs. They play an important role in all aspects of cognition. As such, concepts are studied by several disciplines, such as linguistics, psychology, and philosophy, and these disciplines are interested in the logical and psychological structure of concepts, and how they are put together to form thoughts and sentences. The study of concepts has served as an important flagship of an emerging interdisciplinary approach called cognitive science.
Categorization is something that humans and other organisms do: "doing the right thing with the right kind of thing." The doing can be nonverbal or verbal. For humans, both concrete objects and abstract ideas are recognized, differentiated, and understood through categorization. Objects are usually categorized for some adaptive or pragmatic purpose. Categorization is grounded in the features that distinguish the category's members from nonmembers. Categorization is important in learning, prediction, inference, decision making, language, and many forms of organisms' interaction with their environments.
The embodied mind thesis challenges other theories, such as cognitivism, computationalism, and Cartesian dualism.It is closely related to the extended mind thesis, situated cognition and enactivism. The modern version depends on insights drawn from recent research in psychology, linguistics, cognitive science, dynamical systems, artificial intelligence, robotics, animal cognition, plant cognition and neurobiology.
In psychology, cognitivism is a theoretical framework for understanding the mind that gained credence in the 1950s. The movement was a response to behaviorism, which cognitivists said neglected to explain cognition. Cognitive psychology derived its name from the Latin cognoscere, referring to knowing and information, thus cognitive psychology is an information-processing psychology derived in part from earlier traditions of the investigation of thought and problem solving.
The extended mind thesis (EMT) says that an agent's mind and cognitive processes are neither skull-bound nor even body-bound, but extend into the agent's world. The EMT proposes that some objects in the external environment are utilized by the mind in such a way that the objects can be seen as extensions of the mind itself. Specifically, the mind is seen to encompass every level of the cognitive process, which will often include the use of environmental aids. As Andy Clark and David Chalmers put it in "The Extended Mind" (1998): "Where does the mind stop and the rest of the world begin? ... We propose to pursue ... an active externalism, based on the active role of the environment in driving cognitive processes." The question is raised as to the division point between the mind and the environment.
Situated cognition is a theory that posits that knowing is inseparable from doing by arguing that all knowledge is situated in activity bound to social, cultural and physical contexts.
In philosophy, embodied cognition holds that an agent's cognition is strongly influenced by aspects of an agent's body beyond the brain itself.In their proposal for an enactive approach to cognition Varela et al. defined "embodied":
Philosophy is the study of general and fundamental questions about existence, knowledge, values, reason, mind, and language. Such questions are often posed as problems to be studied or resolved. The term was probably coined by Pythagoras. Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation. Classic philosophical questions include: Is it possible to know anything and to prove it? What is most real? Philosophers also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust? Do humans have free will?
Enactivism argues that cognition arises through a dynamic interaction between an acting organism and its environment. It claims that our environment is one which we selectively create through our capacities to interact with the world. "Organisms do not passively receive information from their environments, which they then translate into internal representations. Natural cognitive systems...participate in the generation of meaning ...engaging in transformational and not merely informational interactions: they enact a world." These authors suggest that the increasing emphasis upon enactive terminology presages a new era in thinking about cognitive science. How the actions involved in enactivism relate to age-old questions about free will remains a topic of active debate.
The Varela enactive definition is broad enough to overlap the views of extended cognition and situated cognition, and indeed, these ideas are not always carefully separated.
Extended cognition is the view that mental processes and mind extend beyond the body to include aspects of the environment in which an organism is embedded and the organism's interaction with that environment. Cognition goes beyond the manipulation of symbols to include the emergence of order and structure evolving from active engagement with the world.
Some authors explain the dependence of cognition upon the body and its environmental interactions by saying cognition in real biological systems is not an end in itself but is constrained by the system's goals and capacities. However, they argue, such constraints do not mean cognition is set by adaptive behavior (or autopoiesis) alone, but cognition requires “some kind of information processing...the transformation or communication of incoming information”, the acquiring of which involves "exploration and modification of the environment".
The term autopoiesis refers to a system capable of reproducing and maintaining itself. The original definition can be found in Autopoiesis and Cognition: the Realization of the Living :
Page 16: It was in these circumstances ... in which he analyzed Don Quixote's dilemma of whether to follow the path of arms or the path of letters, I understood for the first time the power of the word "poiesis" and invented the word that we needed: autopoiesis. This was a word without a history, a word that could directly mean what takes place in the dynamics of the autonomy proper to living systems.
Page 78: An autopoietic machine is a machine organized as a network of processes of production of components which: (i) through their interactions and transformations continuously regenerate and realize the network of processes (relations) that produced them; and (ii) constitute it as a concrete unity in space in which they exist by specifying the topological domain of its realization as such a network.
Page 89: ... the space defined by an autopoietic system is self-contained and cannot be described by using dimensions that define another space. When we refer to our interactions with a concrete autopoietic system, however, we project this system on the space of our manipulations and make a description of this projection.
The separation of embodied cognition from extended cognition and situated cognition can be based upon the embodiment thesis, a narrower view of embodiment than that of Varela et al. or that of Dawson:
This thesis omits direct mention of some aspects of the "more encompassing biological, psychological and cultural context" included by Varela et al. The Extended mind thesis, in contrast with the Embodiment thesis, limits cognitive processing neither to the brain nor even to the body, but extends it outward into the agent's world.Situated cognition emphasizes that this extension is not just a matter of including resources outside the head, but stresses the role of probing and modifying interaction with the agent's world.
In his Universal Natural History and Theory of Heaven (1755).philosopher Immanuel Kant advocated a view of the mind–body problem with parallels to the embodied view. Some difficulties with this interpretation of Kant include (i) the view that Kant holds the empirical, and specifically knowledge of the body, cannot support a priori transcendental claims, and (ii) the view that Kant holds that transcendental philosophy, although charged with the responsibility of explaining how we can have empirical knowledge, is not itself empirical.
José Ortega y Gasset, George Santayana, Miguel de Unamuno, Maurice Merleau-Ponty, Martin Heidegger and others in the broadly existential tradition have proposed philosophies of mind influencing the development of the modern 'embodiment' thesis.
The embodiment movement in artificial intelligence has fueled the embodiment argument in philosophy and a revised view of ethology:
These developments have also given emotions a new status in philosophy of mind as an indispensable constituent, rather than a non-essential addition to rational intellectual thought. In philosophy of mind, the idea that cognition is embodied is sympathetic with other views of cognition such as situated cognition or externalism. This is a radical move towards a total re-localization of mental processes out of the neural domain.
Embodied cognition is a topic of research in social and cognitive psychology, covering issues such as social interaction and decision-making.Embodied cognition reflects the argument that the motor system influences our cognition, just as the mind influences bodily actions. For example, when participants hold a pencil in their teeth engaging the muscles of a smile, they comprehend pleasant sentences faster than unpleasant ones, while holding a pencil between their nose and upper lip to engage the muscles of a frown has the reverse effect.
George Lakoff (a cognitive scientist and linguist) and his collaborators (including Mark Johnson, Mark Turner, and Rafael E. Núñez) have written a series of books promoting and expanding the thesis based on discoveries in cognitive science, such as conceptual metaphor and image schema.Irina Trofimova around the same time experimentally confirmed the phenomena "projection through capacities", as a prototype of the embodiment theory
Robotics researchers such as Rodney Brooks, Hans Moravec and Rolf Pfeifer have argued that true artificial intelligence can only be achieved by machines that have sensory and motor skills and are connected to the world through a body.The insights of these robotics researchers have in turn inspired philosophers like Andy Clark and Horst Hendriks-Jansen.
Neuroscientists Gerald Edelman, António Damásio and others have outlined the connection between the body, individual structures in the brain and aspects of the mind such as consciousness, emotion, self-awareness and will.Biology has also inspired Gregory Bateson, Humberto Maturana, Francisco Varela, Eleanor Rosch and Evan Thompson to develop a closely related version of the idea, which they call enactivism. The motor theory of speech perception proposed by Alvin Liberman and colleagues at the Haskins Laboratories argues that the identification of words is embodied in perception of the bodily movements by which spoken words are made. In related work at Haskins, Paul Mermelstein, Philip Rubin, Louis Goldstein, and colleagues developed articulatory synthesis tools for computationally modeling the physiology and aeroacoustics of the vocal tract, demonstrating how cognition and perception of speech can be shaped by biological constraints. This was extended into the audio-visual domain by the "talking heads" approach of Eric Vatikiotis-Bateson, Rubin, and other colleagues.
One embodied cognition study shows that action intention can affect processing in visual search, with more orientation errors for pointing than for grasping.Participants either pointed to or grasped target objects of 2 colors and 2 orientations (45° and 135°). There were randomized numbers of distractors as well (0, 3, 6, or 9), which differed from the target in color, orientation, or both. A tone sounded to inform participants which target orientation to find. Participants kept their eyes on a fixation point until it turned from red to the target color. The screen then lit up and the participants searched for the target, either pointing to it or grasping it (depending on the block). There were 2 blocks for pointing and 2 for grasping, with the order counterbalanced. Each block had 64 trials.
Results from the experiment show that accuracy decreases with an increase in the number of distractors.Overall, participants made more orientation errors than color errors. There was no main effect of accuracy between the pointing and grasping conditions, but participants made significantly fewer orientation errors in the grasping condition than in the pointing condition. Color errors were the same in both conditions. Because orientation is important in grasping an object, these results fit with the researchers' hypothesis that the plan to grasp an object will aid in orientation accuracy. This supports embodied cognition because action intention (planning to grasp an object) can affect visual processing of task-relevant information (orientation).
Internal states can affect distance perception, which relates to embodied cognition.Researchers randomly assigned college student participants to high-choice, low-choice, and control conditions. The high-choice condition signed a “freedom of choice” consent form indicating their decision to wear a Carmen Miranda costume and walk across a busy area of campus. Low-choice participants signed an “experimenter choice” consent form, indicating the experimenter assigned the participant to wear the costume. A control group walked across campus but did not wear a costume. At the conclusion of the experiment, each participant completed a survey which asked them to estimate the distance they walked.
The high-choice participants perceived the distance walked as significantly shorter than participants in the low-choice and control groups, even though they walked the same distance.The manipulation caused high-choice participants to feel responsible for the choice to walk in the embarrassing costume. This created cognitive dissonance, which refers to a discrepancy between attitudes and behaviors. High-choice participants reconciled their thoughts and actions by perceiving the distance as shorter. These results show the ability of internal states to affect perception of physical distance moved, which illustrates the reciprocal relationship of the body and mind in embodied cognition.
Researchers have found that when making judgements about objects in photographs, people will take the perspective of a person in the picture instead of their own.They showed college undergraduate participants 1 of 3 photographs and asked where 1 object in the picture was compared to the other object. For example, if the 2 objects were an apple and a banana, the participants would have to respond to a question about the location of the apple compared to the banana. The photographs either had no person, a person looking at the object, in this case the banana, or a person reaching for the banana. The photograph and question appeared in a larger set of questionnaires not related to the study.
Results show that participants who viewed photographs that included a person were significantly more likely to respond from another's perspective than those who saw photographs with no person.There were no differences in perspective of responses for the person looking versus reaching. Participants who saw the scene without a person were significantly more likely to respond from their own perspective. This means that the presence of a person in the photograph affected the perspective used even though the question focused solely on the two objects. The researchers state that these results suggest disembodied cognition, in which the participants put themselves into the body of the person in the photograph.
Some researchers extend embodied cognition to include language.They describe language as a tool that aids in broadening our sense of body. For instance, when asked to identify “this” object, participants most often choose an object near to them. Conversely, when asked to identify “that” object, participants choose an object further away from them. Language allows us to distinguish between distances in more complex ways than the simple perceptual difference between near and far objects.
The motor system is involved in language comprehension, in this case when sentences were performable by a human, there was a change in participants' overall movement of a pendulum.Researchers performed an experiment in which college undergraduate participants swung a pendulum while completing a "sentence judgement task." Participants would swing the pendulum with both hands for 10 seconds before a prompt and then a sentence would appear on the screen until the participant responded. In the control condition, participants swung the pendulum without performing the "sentence judgement task." Each trial had half "plausible" and half "implausible" sentences. The "plausible" sentences made sense semantically, while the "implausible" ones did not. The "performable" sentences could be performed by a human, while the "inanimate" sentences could not. Participants responded by saying "yes" to the "plausible" sentences.
Results show a significant "relative phase shift," or overall change in movement of the swinging pendulum, for the "performable" sentences.This change did not occur for "inanimate" sentences or the control condition. The researchers did not expect an overall phase shift, instead they expected a change in the variability of movement, or the "standard deviation of relative phase shift." Although not entirely expected, these results support embodied cognition and show that the motor system is involved in the understanding of language. The researchers suggest that the nature of this relationship needs to be further studied to determine the exact correlation this task has to bi-manual motor movements.
Embodiment effects emerge in the way in which people of different sex and temperament perceive verbal material, such as common adjectives and abstract and neutral nouns. Trofimova, who first described this phenomenon in her experiments, called it "projection through capacities". This phenomenon emerges when people's lexical perception depends upon their capacities to handle the events; when their information processing registers mostly those aspects of objects or of a situation that they can properly react to and deal with according to their inherent capacities.For example, in these studies males with stronger motor-physical endurance estimated abstractions describing people-, work/reality- and time-related concepts in more positive terms than males with a weaker endurance. Females with stronger social or physical endurance estimated social attractors in more positive terms than weaker females. Both male and female temperament groups with higher sociability showed a universal positive bias in their estimations of neutral words, especially for social and work/reality-related concepts, in comparison to participants with lower sociability. Capacities related to the tempo of activities also appeared to impact the perception of lexical material: men with faster motor-physical tempo estimated neutral, abstract time-related concepts significantly in more positive terms than men with slower tempo.
A study examining memory and embodied cognition illustrates that people remember more of the gist of a story when they physically act it out.Researchers divided female participants randomly into 5 groups, which were "Read Only," "Writing," "Collaborative Discussion," "Independent Discussion," and "Improvisation." All participants received a monologue about teen addiction and were told to pay attention to details about the character and action in the monologue. Participants were given 5 minutes to read the monologue twice, unaware of a future recall test. In the "Read Only" condition participants filled out unrelated questionnaires after reading the monologue. In the "Writing" condition participants responded to 5 questions about the story from the perspective of the character in the monologue. They had 6 minutes to answer each question. In the "Collaborative Discussion" condition participants responded from the character's perspective to the same questions as the "Writing" group, but in groups of 4 or 5 women. They were also given 6 minutes per question and everyone participated in answering each question. The "Independent Discussion" condition was the same as the "Collaborative Discussion," except 1 person answered each question. In the "Improvisation" condition participants acted out 5 scenes from the monologue in groups of 5 women. The researchers suggest that this condition involves embodied cognition and will produce better memory for the monologue. Every participant played the main character and a supporting character once. Participants were given short prompts from lines in the monologue, which were excluded from the memory test. Participants had 2 minutes to choose characters and 4 minutes for improvisations. The recall test was the monologue with 96 words or phrases missing. Participants had to fill in the blanks as accurately as possible.
Researchers gave the recall test to a group who did not read the monologue. They scored significantly lower than the other groups, which indicated that guessing was not easy.In coding the answers to the recall test, exact words were labeled "Verbatim", and correct content but varied wording was labeled "Gist". The combination of "Verbatim" and "Gist" was called "Total Memory." The "Improvisational" group had more "Gist" memories than any other group and had more "Total Memory" than both of the discussion groups. The results fit the researchers' hypothesis that the "Improvisational" group would remember more because they actively rehearsed the information from the monologue. Although other groups had also elaborately encoded the information, the "Improvisation" group remembered significantly more than the discussion groups and marginally more than the "Reading Only" and "Writing" groups. Simply experiencing the monologue in an active way aids in remembering the "Gist." There were no differences across groups for "Verbatim" memory, which they suggest could take longer than the limited time during the experiment to develop.
Ideas stemming from embodied cognition research have been applied to the field of learning. It has been shown that bodily activity can be used to enhance learning in several studies.Research on embodied learning often utilizes educational technology in the form of virtual reality, mixed reality, or motion capture to transform learning activities into immersive experiences. There are theoretical approaches that define the level of embodiment of these learning platforms based on factors such as their capabilities for immersion and sensorimotor activity. Other theoretical systems analyze embodied learning in terms of the degree of bodily engagement and whether the embodiment is integrated into a learning task.
A series of experiments demonstrated the interrelation between motor experience and high-level reasoning. For example, although most individuals recruit visual processes when presented with spatial problems such as mental rotation tasksmotor experts favor motor processes to perform the same tasks, with higher overall performance. A related study showed that motor experts use similar processes for the mental rotation of body parts and polygons, whereas non-experts treated these stimuli differently. These results were not due to underlying confounds, as demonstrated by a training study which showed mental rotation improvements after a one-year motor training, compared with controls. Similar patterns were also found in working memory tasks, with the ability to remember movements being greatly disrupted by a secondary verbal task in controls and by a motor task in motor experts, suggesting the involvement of different processes to store movements depending on motor experience, namely verbal for controls and motor for experts.
In research focused on the approach and avoidance effect, people showed an approach effect for positive words.In the "positive toward condition," participants moved positive words toward the center of the screen and negative words away. In the "negative toward condition," participants moved negative words toward the center and positive words away. Participants were given feedback about their accuracy at the end of each of the 4 experimental blocks. In the first experiment the word at the center of the screen had a positive valence, while in the second experiment the central word had a negative valence. In the third experiment, the center of the screen had an empty box.
As predicted, in the first experiment participants in the "positive toward condition" responded significantly faster than those in the "negative toward condition."This fits the approach/avoidance effect in embodied cognition, which states that people are faster to approach positive things and avoid negative ones. In the second experiment, researchers expected participants in the "negative toward condition" to be faster, yet those in the "positive toward condition" responded significantly faster. Although effects were smaller in the third experiment, participants in the "positive toward condition" were still faster. Overall, people were faster in the "positive toward condition," regardless of the valence of the central word. Despite mixed results regarding the researchers' expectations, they maintain that the motor system is important in processing higher level representations such as the action goal. In this study, participants showed strong approach effects in the "positive toward condition," which supports embodied cognition.
As part of a larger study, researchers separated participants into 5 groups with different instructions.In the "approach" condition, participants were instructed to imagine physically moving the product toward them, but in the "avoid" condition, participants had to imagine moving the product away from them. In the "control" condition, participants were instructed to simply observe the product. The "correction" condition involved the same instructions as the approach condition, except participants were told that the body can affect judgment. In the "approach information" condition, participants had to list 5 reasons why they would obtain the product. After viewing a picture of an aversive product, participants rated on a scale of 1 to 7 how desirable the product was and how much they approached of or avoided the product. They also provided how much they would pay for the product.
An approach/avoidance effect was found in relation to product evaluation.Participants in the "approach" condition liked the aversive product significantly more and would pay more for it. There were no differences between the "avoidance," "control," "correction," and "approach information" conditions. Simulation of approach can affect liking and willingness to pay for a product, but the effect can be reversed if the person knows about this influence. This supports embodied cognition.
As part of a larger study, one experiment randomly assigned college undergraduates to 2 groups.In the "muscle-firming" condition participants grasped a pen in their hand, while in the "control" condition participants held the pen in their fingers. The participants were then asked to fill out donations to Haiti for the Red Cross in sealed envelopes. They were told to return the envelope regardless of whether they donated. They also filled out questionnaires about their feelings about the Red Cross, their tendency to donate, their feelings about Haiti, what they thought the purpose of the study was, etc.
Significantly more participants in the "muscle-firming" condition than in the "control" condition donated money.Condition did not affect the actual amount donated when participants chose to donate. As the researchers predicted, the "muscle-firming" condition helped participants get over their physical aversion to viewing the devastation in Haiti and spend money. Muscle-firming in this experiment may also be related to an increase in self-control, suggesting embodied cognition can play a role in self-regulation.
Another set of studies was conducted by Shalev (2014), indicating that exposure to physical or conceptual thirst or dryness-related cues influence perceived energy and reduce self-regulation. In Study 1, participants primed with dryness-related concepts reported greater physical thirst and tiredness and lower subjective vitality. In Study 2, participants who were physically thirsty were less persistent in investing effort in an unsolvable anagram task. In Study 3, images of arid land influenced time preference regarding when to begin preparation to make a monetary investment. Finally, in Studies 4a and 4b, exposure to the names of dryness-related products influenced impressions of the vitality of a target person.
Some suggest that the embodied mind serves self-regulatory processes by combining movement and cognition to reach a goal.Thus, the embodied mind has a facilitative effect. Some judgments, such as the emotion of a face, are detected more quickly when a participant mimics the facial expression that is being evaluated. Individuals holding a pen in their mouths to freeze their facial muscles and make them unable to mimic the expression were less able to judge emotions. Goal-relevant actions may be encouraged by embodied cognition, as evidenced by the automated approach and avoidance of certain environmental cues. Embodied cognition is also influenced by the situation. If one moves in a way previously associated with danger, the body may require a greater level of information processing than if the body moves in a way associated with a benign situation.
Some social psychologists examined embodied cognition and hypothesized that embodied cognition would be supported by embodied rapport.Embodied rapport would be demonstrated by pairs of same-sex strangers using Aron’s paradigm, which instructs participants to alternate asking certain questions and to progressively self-disclose. The researchers predicted that participants would mimic each other’s movements, reflecting embodied cognition. Half the participants completed a control task of reading and editing a scientific article, while half the participants completed a shortened version of Aron’s self-disclosure paradigm.
There is a significant correlation between self-disclosure and positive emotions towards the other participant.Participants randomly assigned to the self-disclosure task displayed more behavioral synchrony (rated by independent judges watching the tapes of each condition on mute) and reported more positive emotions than the control group. Since bodily movements influence the psychological experience of the task, the relationship between self-disclosure and positive feelings towards one's partner may be an example of embodied cognition.
Embodied cognition may also be defined from the perspective of evolutionary psychologists.Evolutionary psychologists view emotion as an important self-regulatory aspect of embodied cognition, and emotion as a motivator towards goal-relevant action. Emotion helps drive adaptive behavior. The evolutionary perspective cites language, both spoken and written, as types of embodied cognition. Pacing and non-verbal communication reflect embodied cognition in spoken language. Technical aspects of written language, such as italics, all caps, and emoticons promote an inner voice and thereby a sense of feeling rather than thinking about a written message.
George Lakoff and his collaborators have developed several lines of evidence that suggest that people use their understanding of familiar physical objects, actions and situations (such as containers, spaces, trajectories) to understand other more complex domains (such as mathematics, relationships or death). Lakoff argues that all cognition is based on knowledge that comes from the body and that other domains are mapped onto our embodied knowledge using a combination of conceptual metaphor, image schema and prototypes.
Lakoff and Mark Johnsonshowed that humans use metaphor ubiquitously and that metaphors operate at a conceptual level (i.e., they map one conceptual domain onto another), they involve an unlimited number of individual expressions and that the same metaphor is used conventionally throughout a culture. Lakoff and his collaborators have collected thousands of examples of conceptual metaphors in many domains.
For example, people will typically use language about journeys to discuss the history and status of a love affair, a metaphor Lakoff and Johnson call "LOVE IS A JOURNEY". It is used in such expression as: "we arrived at a crossroads," "we parted ways", "we hit the rocks" (as in a sea journey), "she's in the driver's seat", or, simply, "we're together". In cases like these, something complex (a love affair) is described in terms of something that can be done with a body (travel through space).
This section needs expansion. You can help by adding to it.(December 2011)
Prototypes are "typical" members of a category, e.g. a robin is a prototypical bird, but a penguin is not. The role of prototypes in human cognition was first identified and studied by Eleanor Rosch in the 1970s.She was able to show that prototypical objects are more easily categorized than non-prototypical objects, and that people answered questions about a category as a whole by reasoning about a prototype. She also identified basic level categories: categories that have prototypes that are easily visualized (such as a chair) and are associated with basic physical motions (such as "sitting"). Prototypes of basic level categories are used to reason about more general categories.
Prototype theory has been used to explain human performance on many different cognitive tasks and in a large variety of domains. George Lakoff argues that prototype theory shows that the categories that people use are based on our experience of having a body and have no resemblance to logical classes or types. For Lakoff, this shows that traditional objectivist accounts of truth cannot be correct.
A classic argument against embodiment in its strict form is based on abstract meaning. Whereas the meanings of the words ‘eye’ and ‘grasp’ can be explained, to a degree, by pointing to objects and actions, those of ‘beauty’ and ‘freedom’ cannot.It may be that some common sensorimotor knowledge is immanent in freeing actions or instantiations of beauty, but it seems likely that additional semantic binding principles are behind such concepts. So might it be necessary, after all, to place abstract semantics in an amodal meaning system? A remarkable observation has recently been offered that may be of the essence in this context: abstract terms show an over-proportionally strong tendency to be semantically linked to knowledge about emotions. This additional embodied–semantic link accounts for advantages in processing speed for abstract emotional terms over otherwise matched control words. In addition, abstract words strongly activate anterior cingulate cortex, a site known to be relevant for emotion processing Thus, it appears that at least some abstract words are semantically grounded in emotion knowledge.
If abstract emotion words indeed receive their meaning through grounding in emotion it is of crucial relevanceTherefore, the link between an abstract emotion word and its abstract concept is via manifestation of the latter in prototypical actions. The child learns an abstract emotion word such as 'joy' because it shows JOY-expressing action schemas, which language-teaching adults use as criteria for correct application of the abstract emotion word Thus, the manifestation of emotions in actions becomes the crucial link between word use and internal state, and hence between sign and meaning. Only after a stock of abstract emotion words has been grounded in emotion-expressing action can further emotion terms be learnt from context.
The experience of AI research provides another line of evidence supporting the embodied mind thesis. In the early history of AI successes in programming high-level reasoning tasks such as chess-playing led to an unfounded optimism that all AI problems would be relatively quickly solved. These programs simulated intelligence using logic and high-level abstract symbols (an approach called Good old-fashioned AI). This "disembodied" approach ran into serious difficulties in the 1970s and 80s, as researchers discovered that abstract, disembodied reasoning was highly inefficient and could not achieve human-levels of competence on many simple tasks.Funding agencies (such as DARPA) withdrew funding because the field of AI had failed to achieve its stated objectives, leading to difficult period now known as the "AI winter". Many AI researchers began to doubt that high level symbolic reasoning could ever perform well enough to solve simple problems.
Rodney Brooks argued in the mid-80s that these symbolic approaches were failing because researchers did not appreciate the importance of sensorimotor skills to intelligence in general, and applied these principals to robotics (an approach he called "Nouvelle AI"). Another successful new direction was neural networks—programs based on the actual structures within human bodies that gave rise to intelligence and learning. In the 90s, statistical AI achieved high levels of success in industry without using any symbolic reasoning, but instead using probabilistic techniques to make "guesses" and improve them incrementally. This process is similar to the way human beings are able to make fast, intuitive choices without stopping to reason symbolically.
Moravec's paradox is the discovery by artificial intelligence and robotics researchers that, contrary to traditional assumptions, high-level reasoning requires very little computation, but low-level sensorimotor skills require enormous computational resources. The principle was articulated by Hans Moravec (whence the name) and others in the 1980s.
As Moravec writes:
Encoded in the large, highly evolved sensory and motor portions of the human brain is a billion years of experience about the nature of the world and how to survive in it. The deliberate process we call reasoning is, I believe, the thinnest veneer of human thought, effective only because it is supported by this much older and much powerful, though usually unconscious, sensorimotor knowledge. We are all prodigious olympians in perceptual and motor areas, so good that we make the difficult look easy. Abstract thought, though, is a new trick, perhaps less than 100 thousand years old. We have not yet mastered it. It is not all that intrinsically difficult; it just seems so when we do it.
Many artificial intelligence researchers have argued that a machine may need a human-like body to think and speak as well as a human being. As early as 1950, Alan Turing wrote:
It can also be maintained that it is best to provide the machine with the best sense organs that money can
buy, and then teach it to understand and speak English. That process could follow the normal teaching of a
child. Things would be pointed out and named, etc. (Turing, 1950).
Embodiment theory was brought into artificial intelligence most notably by Rodney Brooks who showed in the 1980s that robots could be more effective if they 'thought' (planned or processed) and perceived as little as possible. The robot's intelligence is geared towards only handling the minimal amount of information necessary to make its behavior be appropriate and/or as desired by its creator.
Others have argued that without taking into account both the architecture of the human brain, and embodiment, it is unrealistic to replicate accurately the processes which take place during language acquisition, comprehension, production, or during non-linguistic actions.There have thus been suggestions that while robots are far from isomorphic with humans, they could benefit from strengthened associative connections in the optimization of their processes and their reactivity and sensitivity to environmental stimuli, and in situated human-machine interaction, and that the concept of multisensory integration be extended to cover linguistic input and the complementary information combined from temporally coincident sensory impressions.
The embodied approach to AI has been given several names by different schools of researchers, including: Nouvelle AI (Brooks' term), Situated AI, Behavior based AI and Embodied cognitive science.

One source of inspiration for embodiment theory has been research in cognitive neuroscience, such as the proposals of Gerald Edelman concerning how mathematical and computational models such as neuronal group selection and neural degeneracy result in emergent categorization.
Rohrer (2005) discusses how both our neural and developmental embodiment shape both our mental and linguistic categorizations. The degree of thought abstraction has been found to be associated with physical distance which then affects associated ideas and perception of risk.
The embodied mind thesis is compatible with some views of cognition promoted in neuropsychology, such as the theories of consciousness of Vilayanur S. Ramachandran, Gerald Edelman, and Antonio Damasio.
The modeling work of cognitive neuroscientists such as Francisco Varela and Walter Freeman seeks to explain embodied and situated cognition in terms of dynamical systems theory and neurophenomenology, but rejects the idea that the brain uses representations to do so (a position also espoused by Gerhard Werner).
Research on embodied cognition is extremely broad, covering a wide range of concepts. Methods to study embodied cognition vary from experiment to experiment based on the operational definition used by researchers. There is much evidence for embodied cognition, although interpretation of results and their significance may be disputed. Researchers continue to search for the best way to study and interpret embodied cognition.
Somecriticize the notion that pre-verbal children provide an ideal channel for studying embodied cognition, especially embodied social cognition. It may be impossible to know when a pre-verbal infant is a "pure model" of embodied cognition, since infants experience dramatic changes in social behavior throughout development. A 9-month old has reached a different developmental stage than a 2-month old. Looking-time and reaching measures of embodied cognition may not represent embodied cognition since infants develop object permanence of objects they can see before they develop object permanence with objects they can touch. True embodied cognition suggests that children would have to first physically engage with an object to understand object permanence.
The response to this critique is that infants are "ideal models" of embodied cognition.Infants are the best models because they utilize symbols less than adults do. Looking-time could likely be a better measure of embodied cognition than reaching because infants have not developed certain fine motor skills yet. Infants may first develop a passive mode of embodied cognition before they develop the active mode involving fine motor movements.
Some criticize the conclusions made by researchers about embodied cognition.The pencil-in-teeth study is frequently cited as an example of these invalidly drawn conclusions. The researchers believed that the quicker responses to positive sentences by participants engaging their smiling muscles represented embodied cognition. However, opponents argue that the effects of this exercise were primed or facilitated by the engagement of certain facial muscles. Many cases of facilitative movements of the body may be incorrectly labeled as evidence of embodied cognition.
The following "Six Views of Embodied Cognition" are taken from Margaret Wilson:
Margaret Wilson adds: "Some authors go so far as to complain that the phrase 'situated cognition' implies, falsely, that there also exists cognition that is not situated (Greeno & Moore, 1993, p. 50)."Of her six claims, she notes in her abstract, "the first three and the fifth claim appear to be at least partially true, and their usefulness is best evaluated in terms of the range of their applicability. The fourth claim, I argue, is deeply problematic. The sixth claim has received the least attention, but it may in fact be the best documented and most powerful of the six claims."
Cognitive science is the interdisciplinary, scientific study of the mind and its processes. It examines the nature, the tasks, and the functions of cognition. Cognitive scientists study intelligence and behavior, with a focus on how nervous systems represent, process, and transform information. Mental faculties of concern to cognitive scientists include language, perception, memory, attention, reasoning, and emotion; to understand these faculties, cognitive scientists borrow from fields such as linguistics, psychology, artificial intelligence, philosophy, neuroscience, and anthropology. The typical analysis of cognitive science spans many levels of organization, from learning and decision to logic and planning; from neural circuitry to modular brain organization. The fundamental concept of cognitive science is that "thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structures."
Thought encompasses an "aim-oriented flow of ideas and associations that can lead to a reality-oriented conclusion". Although thinking is an activity of an existential value for humans, there is still no consensus as to how it is adequately defined or understood.
Francisco Javier Varela García was a Chilean biologist, philosopher, and neuroscientist who, together with his mentor Humberto Maturana, is best known for introducing the concept of autopoiesis to biology, and for co-founding the Mind and Life Institute to promote dialog between science and Buddhism.
Wishful thinking describes decision-making and the formation of beliefs based on what might be pleasing to imagine, rather than on evidence, rationality, or reality. It is a product of resolving conflicts between, belief, and desire.
A mental image or mental picture is an experience that, on most occasions, significantly resembles the experience of perceiving some object, event, or scene, but occurs when the relevant object, event, or scene is not actually present to the senses. There are sometimes episodes, particularly on falling asleep and waking up (hypnopompic), when the mental imagery, being of a rapid, phantasmagoric and involuntary character, defies perception, presenting a kaleidoscopic field, in which no distinct object can be discerned. Mental imagery can sometimes produce the same effects as would be produced by the behavior or experience imagined.
Embodied cognitive science is an interdisciplinary field of research, the aim of which is to explain the mechanisms underlying intelligent behavior. It comprises three main methodologies: 1) the modeling of psychological and biological systems in a holistic manner that considers the mind and body as a single entity, 2) the formation of a common set of general principles of intelligent behavior, and 3) the experimental use of robotic agents in controlled environments.
Embodied music cognition is a direction within systematic musicology interested in studying the role of the human body in relation to all musical activities.
The concept of motor cognition grasps the notion that cognition is embodied in action, and that the motor system participates in what is usually considered as mental processing, including those involved in social interaction. The fundamental unit of the motor cognition paradigm is action, defined as the movements produced to satisfy an intention towards a specific motor goal, or in reaction to a meaningful event in the physical and social environments. Motor cognition takes into account the preparation and production of actions, as well as the processes involved in recognizing, predicting, mimicking and understanding the behavior of other people. This paradigm has received a great deal of attention and empirical support in recent years from a variety of research domains including developmental psychology, cognitive neuroscience, and social psychology.
Biological motion is motion that comes from actions of a biological organism. Humans and animals are able to understand those actions through experience, identification, and higher level neural processing. Humans use biological motion to identify and understand familiar actions, which is involved in the neural processes for empathy, communication, and understanding other's intentions. The neural network for biological motion is highly sensitive to the observer's prior experience with the action's biological motions, allowing for embodied learning. This is related to a research field that is broadly known as embodied cognitive science, along with research on mirror neurons.
Common coding theory is a cognitive psychology theory describing how perceptual representations and motor representations are linked. The theory claims that there is a shared representation for both perception and action. More important, seeing an event activates the action associated with that event, and performing an action activates the associated perceptual event.
Vittorio Gallese is professor of Psychobiology at the University of Parma, Italy, and was professor in Experimental Aesthetics at the University of London, UK (2016-2018). He is an expert in neurophysiology, cognitive neuroscience, social neuroscience, and philosophy of mind. Gallese is one of the discoverers of mirror neurons. His research attempts to elucidate the functional organization of brain mechanisms underlying social cognition, including action understanding, empathy, language, mindreading and aesthetic experience.
Paula M. Niedenthal is a social psychologist currently working as a Professor of Psychology at the University of Wisconsin–Madison. She also completed her undergraduate studies at the University of Wisconsin at Madison where she received a Bachelor's in Psychology. She then received her Ph.D. at the University of Michigan before becoming a faculty member of the departments of Psychology at Johns Hopkins University and Indiana University. Until recently, she served as the Director of Research in the National Centre for Scientific Research at the Université Blaise Pascal in Clermont-Ferrand France.

Niedenthal has authored more than 80 articles and chapters, and several books. Niedenthal is a fellow of the Society for Personality and Social Psychology.
Embodied cognition occurs when an organism’s sensorimotor capacities, body and environment play an important role in thinking. The way in which a person’s body and their surroundings interacts also allows for specific brain functions to develop and in the future to be able to act. This means that not only does the mind influence the body’s movements, but the body also influences the abilities of the mind, also termed the bi-directional hypothesis. There are three generalizations that are assumed to be true relating to embodied cognition. A person's motor system is activated when (1) they observe manipulable objects, (2) process action verbs, and (3) observe another individual's movements.
Ezequiel A Di Paolo is a full-time Research Professor at Ikerbasque, the Basque Foundation for Science. He also has affiliations with the Centre for Computational Neuroscience and Robotics at the University of Sussex. His field of research covers enactivism and embodiment in cognitive science.
Embodied design grows from the idea of embodied cognition: that the actions of the body can play a role in the development of thought and ideas. Embodied design brings mathematics to life; studying the effects of the body on the mind, researchers learn how to design objects and activities for learning. Embodiment is an aspect of pattern recognition in all fields of human endeavor.
Embodied bilingual language, also known as L2 embodiment, is the idea that people mentally simulate their actions, perceptions, and emotions when speaking and understanding a second language (L2) as with their first language (L1). It is closely related to embodied cognition and embodied language processing, both of which only refer to native language thinking and speaking. An example of embodied bilingual language would be situation in which a L1 English speaker learning Spanish as a second language hears the word rápido ("fast") in Spanish while taking notes and then proceeds to take notes more quickly.
The bi-directional hypothesis of language and action proposes that the sensorimotor and language comprehension areas of the brain exert reciprocal influence over one another. This hypothesis argues that areas of the brain involved in movement and sensation, as well as movement itself, influence cognitive processes such as language comprehension. In addition, the reverse effect is argued, where it is proposed that language comprehension influences movement and sensation. Proponents of the bi-directional hypothesis of language and action conduct and interpret linguistic, cognitive, and movement studies within the framework of embodied cognition and embodied language processing. Embodied language developed from embodied cognition, and proposes that sensorimotor systems are not only involved in the comprehension of language, but that they are necessary for understanding the semantic meaning of words.
Social cognitive neuroscience is the scientific study of the biological processes underpinning social cognition. Specifically, it uses the tools of neuroscience to study "the mental mechanisms that create, frame, regulate, and respond to our experience of the social world". Social cognitive neuroscience uses the epistemological foundations of cognitive neuroscience, and is closely related to social neuroscience. Social cognitive neuroscience employs human neuroimaging, typically using functional magnetic resonance imaging (fMRI). Human brain stimulation techniques such as transcranial magnetic stimulation and transcranial direct-current stimulation are also used. In nonhuman animals, direct electrophysiological recordings and electrical stimulation of single cells and neuronal populations are utilized for investigating lower-level social cognitive processes.
