Andrew N. Meltzoff (born February 9,1950) 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.
Meltzoff received a B.A. from Harvard University in 1972 and a D.Phil. (Ph.D.) from Oxford University in 1976 with Jerome Bruner as his thesis advisor. A professor of psychology at the University of Washington since 1988,he is currently co-director of the University of Washington Institute for Learning and Brain Sciences. The institute is an interdisciplinary scientific research center on human learning.
He is married to the internationally recognized speech and hearing scientist and language acquisition researcher Patricia K. Kuhl.
In 1977,Science published the ground-breaking paper "Imitation of Facial and Manual Gestures by Human Neonates" by Meltzoff,who was still at Oxford,and M. Keith Moore of the University of Washington. [1] According to the abstract,
Infants between 12 and 21 days of age can imitate both facial and manual gestures; this behavior cannot be explained in terms of either conditioning or innate releasing mechanisms. Such imitation implies that human neonates can equate their own unseen behaviors with gestures they see others perform.
Six infants were each shown three facial gestures and one manual gesture, sequentially. Their responses were videotaped and scored by observers who did not know which gesture the infants had seen. The statistically significant results showed that infants of this young age were able to imitate all four gestures.
The experiment was ground-breaking because it showed infant imitation of adults at a much earlier age than was thought possible. Jean Piaget, for instance, had thought that infants reached the stage of facial imitation at 8 to 12 months. The study also showed early facial imitation, something previously thought to be impossible at this young age because of its necessarily crossmodal nature. (Infants can see others' faces but not their own; they can feel their own facial movements, but not those of others.) The findings had implications not only for theoretical psychology, but also for the study of memory, learning, language acquisition, and socialization.
A similar study was later done with a group of 40 infants with a mean age of 72 hours (youngest 42 minutes), with the same results, showing that the intermodal mapping infants displayed was unlikely to be learned. [2] However, later studies have suggested that while neonatal imitation of tongue protrusion is widespread, the findings for the imitation of other gestures at this young age are more mixed. [3] [4]
Preverbal infant psychology is notoriously difficult to study. Meltzoff and his colleagues had to develop new techniques for eliciting and interpreting infant responses to stimuli. One method was measuring an infant's visual preference for an object. In one study, infants were allowed to touch but not see a distinctively shaped object. Later they were shown (but could not touch) that object and a different object. The length of time they gazed at each object was measured. Infants looked longer at the object they had previously touched, thus demonstrating an ability to recognize the object with a different sense. [5]
In another experiment, babies' sucking on a pacifier was recorded, and a picture was shown to them. When the sucking stopped, the picture disappeared. Babies were found to suck longer when the picture showed a familiar face than when it showed an unfamiliar one.
Later research has included the investigation of memory; [6] communications development in young children with autism; [7] intention;. [8] In collaboration with neuroscientist Jean Decety, Meltzoff has started to investigate the neural mechanisms underpinning imitation [9] [10] [11] empathy [12] [13] and gaze-following. [14]
Based on his work on imitation, Meltzoff has developed the "like me" hypothesis of infant development. This involves three steps. First, there is an intrinsic, supramodal connection in the infant mind between observed acts and similar executed acts (the correspondence reported in the 1977 and 1983 studies cited above). Secondly, infants experience a regular association between their own acts and their own underlying mental states. This is based on everyday experience. Third, infants project their own internal experiences onto others performing similar acts. As a result, infants begin to acquire an understanding of other minds and their mental states (desires, visual perception and basic emotions, for instance).
This hypothesis suggests that it is imitation that is inborn, and the understanding of other's mental states is a consequence. Other researchers have suggested the opposite, that imitation is a consequence of an understanding of others. But Meltzoff's early imitation studies clearly favor the former possibility. [15]
Empathy is generally described as the ability to take on another's perspective, to understand, feel and possibly share and respond to their experience. There are more definitions of empathy that include but is not limited to social, cognitive, and emotional processes primarily concerned with understanding others. Often times, empathy is considered to be a broad term, and broken down into more specific concepts and types that include cognitive empathy, emotional empathy, somatic empathy, and spiritual empathy.
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.
Object permanence is the understanding that whether an object can be sensed has no effect on whether it continues to exist. This is a fundamental concept studied in the field of developmental psychology, the subfield of psychology that addresses the development of young children's social and mental capacities. There is not yet scientific consensus on when the understanding of object permanence emerges in human development.
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.
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.
Eye contact occurs when two people or animals look at each other's eyes at the same time. In people, eye contact is a form of nonverbal communication and can have a large influence on social behavior. Coined in the early to mid-1960s, the term came from the West to often define the act as a meaningful and important sign of confidence and respect. The customs, meaning, and significance of eye contact can vary greatly between societies, neurotypes, and religions.
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.
Social neuroscience is an interdisciplinary field devoted to understanding the relationship between social experiences and biological systems. Humans are fundamentally a social species, rather than solitary. As such, Homo sapiens create emergent organizations beyond the individual—structures that range from dyads, families, and groups to cities, civilizations, and cultures. In this regard, studies indicate that various social influences, including life events, poverty, unemployment and loneliness can influence health related biomarkers. The term "social neuroscience" can be traced to a publication entitled "Social Neuroscience Bulletin" which was published quarterly between 1988 and 1994. The term was subsequently popularized in an article by John Cacioppo and Gary Berntson, published in the American Psychologist in 1992. Cacioppo and Berntson are considered as the legitimate fathers of social neuroscience. Still a young field, social neuroscience is closely related to personality neuroscience, affective neuroscience and cognitive neuroscience, focusing on how the brain mediates social interactions. The biological underpinnings of social cognition are investigated in social cognitive neuroscience.
Jean Decety is an American–French neuroscientist specializing in developmental neuroscience, affective neuroscience, and social neuroscience. His research focuses on the psychological and neurobiological mechanisms underpinning social cognition, particularly social decision-making, empathy, moral reasoning, altruism, pro-social behavior, and more generally interpersonal relationships. He is Irving B. Harris Distinguished Service Professor at the University of Chicago.
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.
Typically researched in infants, intermodal mapping refers to the ability to gather information about a particular stimulus by integrating multiple senses. Researched by American psychologists Andrew N. Meltzoff and M. Keith Moore, this capability plays an underlying part in neonatal imitation.
Joint attention or shared attention is the shared focus of two individuals on an object. It is achieved when one individual alerts another to an object by means of eye-gazing, pointing or other verbal or non-verbal indications. An individual gazes at another individual, points to an object and then returns their gaze to the individual. Scaife and Bruner were the first researchers to present a cross-sectional description of children's ability to follow eye gaze in 1975. They found that most eight- to ten-month-old children followed a line of regard, and that all 11- to 14-month-old children did so. This early research showed it was possible for an adult to bring certain objects in the environment to an infant's attention using eye gaze.

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.
Wolfgang Prinz is a German cognitive psychologist. He is the director of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, and an internationally recognized expert in experimental psychology, cognitive psychology and philosophy of mind. He is the founder of the common coding theory between perception and action that has a significant impact in cognitive neuroscience and social cognition.
The sense of agency (SA), or sense of control, is the subjective awareness of initiating, executing, and controlling one's own volitional actions in the world. It is the pre-reflective awareness or implicit sense that it is I who is executing bodily movement(s) or thinking thoughts. In non-pathological experience, the SA is tightly integrated with one's "sense of ownership" (SO), which is the pre-reflective awareness or implicit sense that one is the owner of an action, movement or thought. If someone else were to move your arm you would certainly have sensed that it were your arm that moved and thus a sense of ownership (SO) for that movement. However, you would not have felt that you were the author of the movement; you would not have a sense of agency (SA).
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.
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.
Interaction theory (IT) is an approach to questions about social cognition, or how one understands other people, that focuses on bodily behaviors and environmental contexts rather than on mental processes. IT argues against two other contemporary approaches to social cognition, namely theory theory (TT) and simulation theory (ST). For TT and ST, the primary way of understanding others is by means of ‘mindreading’ or ‘mentalizing’ – processes that depend on either theoretical inference from folk psychology, or simulation. In contrast, for IT, the minds of others are understood primarily through our embodied interactive relations. IT draws on interdisciplinary studies and appeals to evidence developed in developmental psychology, phenomenology, and neuroscience.
The eye-contact effect is a psychological phenomenon in human selective attention and cognition. It is the effect that the perception of eye contact with another human face has on certain mechanisms in the brain. This contact has been shown to increase activation in certain areas of what has been termed the ‘social brain’. This social brain network processes social information as the face, theory of mind, empathy, and goal-directedness.
