Intermodal mapping

Last updated

Typically researched in infants, intermodal mapping refers to the ability to gather information about a particular stimulus by integrating multiple senses. [1] Researched by American psychologists Andrew N. Meltzoff and M. Keith Moore, this capability plays an underlying part in neonatal imitation (infant capacity to model observable adult behavior). [2]

Origin

Modern investigation into the field of neonatal imitation and intermodal modeling began with Meltzoff and Moore's seminal study in 1977, investigating 12 to 21-day-old infants and their ability to replicate adults’ facial and manual gestures. [3] They acknowledge opposing voices who argues replication of observed behaviors is “merely arousal of oral activity,” with the evidence of imitation of three facial gestures and one manual gesture. [3]

The history of the intermodal model began when  Meltzoff and Moore defined it as an innate human ability, essential to imitation. They hypothesized intermodal mapping acted as a sequence in which an infant observes an adult's facial acts and creates a “supramodal” framework. With proprioceptive feedback, an infant can then distinguish whether their actions are equivalent to those they see. [2] Therefore, stimuli are not necessarily restricted to a singular sense, but allow them to exist universally in the brain and integrate in ways to produce complex outcomes. This is illustrated specifically in how visual and proprioceptive systems (senses) integrate to aid imitation. Meltzoff and Moore's studies typically mirror the Headturn Preference Procedure (HPP) as they observe both behavior in relation to response time in infants.

Criticism

Criticisms of this approach typically question the innate, or inborn, claims Meltzoff and Moore make. Overall, researchers doubt the possibility that infants have the inherent ability to observe and create their own sequence of movements producing the same “configurations” or actions of the adults they're modeling. [4] In addition, critics question how the link between visual input and motor faculties can be made so early in the infant's development. [4]

Neurological explanation

Meltzoff and Moore describe a neurological explanation claiming mirror neurons as the true mechanism linking “sensory input from observed actions to motor programs.” [4] Found in the adult rhesus monkey cortex, similar areas in the human cortex are thought to also contain these neurons, although evidence is still debated. [4] Theoretically, both the intermodal mapping model and mirror neurons function through automatic low-level processes meant to facilitate imitation. With Hebbian Theory in mind, mirror neurons cannot be innate. They could, however, gain responsiveness through “postnatal experience,” which Meltzoff acknowledges as a part of the intermodal model's nature as an imitation mechanism. [4]

Replication

Several French institutions have involved themselves in this hypothesis and tested its relation to infants, specifically the Centre des Sciences du Goût et de l'Alimentation, Dijon, France; the Centre Emotion, Hôpital de la Salpêtrière, Paris, France, and the Unité de Psychiatrie Périnatale, Maternité Ambroise Paré, Bourg-La-Reine, France. [5] In the Soussignan, et al. 2011 study “Human newborns match tongue protrusion of disembodied human and robotic mouths”, researchers replicate the Meltzoff and Moore position with 2D stimuli. [5] As a result, this research reinforces the intermodal mapping hypothesis, adding that repeated experience and associative sequence learning are crucial components to this hypothesis. [5] However, other studies have failed to replicate Meltzoff and Moore's findings. Maurer, Stager, and Mondlock's study “Cross-modal transfer of shape is difficult to demonstrate in 1-month-olds” (1999) first criticized Meltzoff for “lacking important controls.” [6] Yet, after those were included, Maurer et al. (1999) failed to replicate Meltzoff's findings. [6]

Observational learning is learning that occurs through observing the behavior of others. It is a form of social learning which takes various forms, based on various processes. In humans, this form of learning seems to not need reinforcement to occur, but instead, requires a social model such as a parent, sibling, friend, or teacher with surroundings. Particularly in childhood, a model is someone of authority or higher status in an environment. In animals, observational learning is often based on classical conditioning, in which an instinctive behavior is elicited by observing the behavior of another, but other processes may be involved as well.

An infant or baby is the very young offspring of human beings. Infant is a formal or specialised synonym for the common term baby. The terms may also be used to refer to juveniles of other organisms. A newborn is, in colloquial use, an infant who is only hours, days, or up to one month old. In medical contexts, a newborn or neonate is an infant in the first 28 days after birth; the term applies to premature, full term, and postmature infants.

A facial expression is one or more motions or positions of the muscles beneath the skin of the face. According to one set of controversial theories, these movements convey the emotional state of an individual to observers. Facial expressions are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species.

<span class="mw-page-title-main">Gesture</span> Form of non-verbal/non-vocal communication

A gesture is a form of non-verbal communication or non-vocal communication in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, speech. Gestures include movement of the hands, face, or other parts of the body. Gestures differ from physical non-verbal communication that does not communicate specific messages, such as purely expressive displays, proxemics, or displays of joint attention. Gestures allow individuals to communicate a variety of feelings and thoughts, from contempt and hostility to approval and affection, often together with body language in addition to words when they speak. Gesticulation and speech work independently of each other, but join to provide emphasis and meaning.

In psychology, theory of mind refers to the capacity to understand other people by ascribing mental states to them. A theory of mind includes the knowledge that others' beliefs, desires, intentions, emotions, and thoughts may be different from one's own. Possessing a functional theory of mind is crucial for success in everyday human social interactions. People utilise a theory of mind when analyzing, judging, and inferring others' behaviors. The discovery and development of theory of mind primarily came from studies done with animals and infants. Factors including drug and alcohol consumption, language development, cognitive delays, age, and culture can affect a person's capacity to display theory of mind. Having a theory of mind is similar to but not identical with having the capacity for empathy or sympathy.

<span class="mw-page-title-main">Imitation</span> Behaviour in which an individual observes and replicates anothers behaviour

Imitation is a behavior whereby an individual observes and replicates another's behavior. Imitation is also a form of that leads to the "development of traditions, and ultimately our culture. It allows for the transfer of information between individuals and down generations without the need for genetic inheritance." The word imitation can be applied in many contexts, ranging from animal training to politics. The term generally refers to conscious behavior; subconscious imitation is termed mirroring.

A mirror neuron is a neuron that fires both when an organism acts and when the organism observes the same action performed by another. Thus, the neuron "mirrors" the behavior of the other, as though the observer were itself acting. Mirror neurons are not always physiologically distinct from other types of neurons in the brain; their main differentiating factor is their response patterns. By this definition, such neurons have been directly observed in humans and primate species, and in birds.

<span class="mw-page-title-main">Mu wave</span> Electrical activity in the part of the brain controlling voluntary movement

The sensorimotor mu rhythm, also known as mu wave, comb or wicket rhythms or arciform rhythms, are synchronized patterns of electrical activity involving large numbers of neurons, probably of the pyramidal type, in the part of the brain that controls voluntary movement. These patterns as measured by electroencephalography (EEG), magnetoencephalography (MEG), or electrocorticography (ECoG), repeat at a frequency of 7.5–12.5 Hz, and are most prominent when the body is physically at rest. Unlike the alpha wave, which occurs at a similar frequency over the resting visual cortex at the back of the scalp, the mu rhythm is found over the motor cortex, in a band approximately from ear to ear. People suppress mu rhythms when they perform motor actions or, with practice, when they visualize performing motor actions. This suppression is called desynchronization of the wave because EEG wave forms are caused by large numbers of neurons firing in synchrony. The mu rhythm is even suppressed when one observes another person performing a motor action or an abstract motion with biological characteristics. Researchers such as V. S. Ramachandran and colleagues have suggested that this is a sign that the mirror neuron system is involved in mu rhythm suppression, although others disagree.

<span class="mw-page-title-main">Mirroring</span> Subconscious imitative behaviour

Mirroring is the behavior in which one person subconsciously imitates the gesture, speech pattern, or attitude of another. Mirroring often occurs in social situations, particularly in the company of close friends or family, often going unnoticed by both parties. The concept often affects other individuals' notions about the individual that is exhibiting mirroring behaviors, which can lead to the individual building rapport with others.

Andrew N. Meltzoff is an American psychologist and an internationally recognized expert on infant and child development. His discoveries about infant imitation greatly advanced the scientific understanding of early cognition, personality and brain development.

The simulation theory of empathy holds that humans anticipate and make sense of the behavior of others by activating mental processes that, if they culminated in action, would produce similar behavior. This includes intentional behavior as well as the expression of emotions. The theory says that children use their own emotions to predict what others will do; we project our own mental states onto others.

Modeling is:

  1. a method used in certain cognitive-behavioral techniques of psychotherapy whereby the client learns by imitation alone, without any specific verbal direction by the therapist, and
  2. a general process in which persons serve as models for others, exhibiting the behavior to be imitated by the others This process is most commonly discussed with respect to children.

Infant cognitive development is the first stage of human cognitive development, in the youngest children. The academic field of infant cognitive development studies of how psychological processes involved in thinking and knowing develop in young children. Information is acquired in a number of ways including through sight, sound, touch, taste, smell and language, all of which require processing by our cognitive system. However, cognition begins through social bonds between children and caregivers, which gradually increase through the essential motive force of Shared intentionality. The notion of Shared intentionality describes unaware processes during social learning at the onset of life when organisms in the simple reflexes substage of the sensorimotor stage of cognitive development do not maintain communication via the sensory system.

Associative sequence learning (ASL) is a neuroscientific theory that attempts to explain how mirror neurons are able to match observed and performed actions, and how individuals are able to imitate body movements. The theory was proposed by Cecilia Heyes in 2000.. A conceptually similar model proposed by Christian Keysers and David Perrett, based on what we know about the neural properties of mirror neurons and spike-timing-dependent plasticity is the Hebbian learning account of mirror neurons.

Speech repetition occurs when individuals speak the sounds that they have heard another person pronounce or say. In other words, it is the saying by one individual of the spoken vocalizations made by another individual. Speech repetition requires the person repeating the utterance to have the ability to map the sounds that they hear from the other person's oral pronunciation to similar places and manners of articulation in their own vocal tract.

The study of memory incorporates research methodologies from neuropsychology, human development and animal testing using a wide range of species. The complex phenomenon of memory is explored by combining evidence from many areas of research. New technologies, experimental methods and animal experimentation have led to an increased understanding of the workings of memory.

<span class="mw-page-title-main">Embodied cognition</span> Interdisciplinary theory

Embodied cognition is the concept suggesting that many features of cognition are shaped by the state and capacities of the organism. The cognitive features include a wide spectrum of cognitive functions, such as perception biases, memory recall, comprehension and high-level mental constructs and performance on various cognitive tasks. The bodily aspects involve the motor system, the perceptual system, the bodily interactions with the environment (situatedness), and the assumptions about the world built the functional structure of organism's brain and body.

Social cues are verbal or non-verbal signals expressed through the face, body, voice, motion and guide conversations as well as other social interactions by influencing our impressions of and responses to others. These percepts are important communicative tools as they convey important social and contextual information and therefore facilitate social understanding.

Epidemiology of representations, or cultural epidemiology, is a theory for explaining cultural phenomena by examining how mental representations get distributed within a population. The theory uses medical epidemiology as its chief analogy, because "...macro-phenomena such as endemic and epidemic diseases are unpacked in terms of patterns of micro-phenomena of individual pathology and inter-individual transmission". Representations transfer via so-called "cognitive causal chains" ; these representations constitute a cultural phenomenon by achieving stability of public production and mental representation within the existing ecology and psychology of a populace, the latter including properties of the human mind. Cultural epidemiologists have emphasized the significance of evolved properties, such as the existence of naïve theories, domain-specific abilities and principles of relevance.
