The development of copying behaviours of a group of infants from 9 to 15 months of age is analysed. These behaviours are classified according to their type (mimetic or imitated) and function (instrumental, social or hybrid). The function of the behaviours is derived from observable indicators linked to dyadic interaction. Mimetic behaviours are…

The authors of this study examined the relationship between motor imitation behaviors and social communication behaviors in 15-18-month-old infants, using a quantitative correlational research design. Imitation behaviors have been shown to be an index of later social cognition and language development, and a critical mechanism in language learning…

The meaning, mechanism, and function of imitation in early infancy have been actively discussed since Meltzoff and Moore's (1977) report of facial and manual imitation by human neonates. Oostenbroek et al. (2016) claim to challenge the existence of early imitation and to counter all interpretations so far offered. Such claims, if true, would have…

Recent research has shown that infants are more likely to engage with in-group over out-group members. However, it is not known whether infants' learning is influenced by a model's group membership. This study investigated whether 14-month-olds ("N" = 66) selectively imitate and adopt the preferences of in-group versus out-group members.…

No evidence had been provided so far of newborns' capacity to give a matching response to 2D stimuli. We report evidence from 18 newborns who were presented with three types of stimuli on a 2D screen. The stimuli were video-recorded displays of tongue protrusion shown by: (a) a human face, (b) a human tongue from a disembodied mouth, and (c) an…

Imitation requires the imitator to solve the correspondence problem--to translate visual information from modelled action into matching motor output. It has been widely accepted for some 30 years that the correspondence problem is solved by a specialized, innate cognitive mechanism. This is the conclusion of a poverty of the stimulus argument,…

To determine whether children with autism (CWA) would selectively imitate intentional, as opposed to accidental actions, an experimenter demonstrated either an "intentional" and an "accidental" action or two "intentional" actions on the same toy [Carpenter, Akhtar, & Tomasello ("1998a") "Infant Behavior and Development, 21," 315-330]. CWA tended…

This paper offers a review of the literature on the role of imitation in the earliest stages of social interaction between babies and familiar partners. The review focuses on the ways in which reciprocal imitation marks familiar relationships that provide special contexts for babies to engage actively and exuberantly in the construction of a…

Sixteen white home-reared babies (eight boys - eight girls) ranging in age from six months to two years were studied during home visits. Piaget's sensory-motor development theory of imitation was employed, and his special thesis of the hierarchical sequence was tested. The examiner proposed four critieria for assessing the development of imitation…

Ability of 26 newborns to imitate facial expressions was examined. When infants observed emotional facial expressions, they did not show imitative matching of the modeled expressions. However, when tongue protrusion was modeled, infants did produce the modeled gesture. (PCB)

Infant imitation is considered a significant component of social, cognitive, and language development. Observation of 20 infants and their mothers in 2 naturalistic settings at 4 separate ages revealed dyads' imitation and matching in vocal, verbal and action behaviors. Verbal matching increased over the second year, suggesting relation of dyads'…

Twenty-five newborn infants were tested for auditory-oral matching behavior when presented with the consonant sound /m/ and the vowel sound /a/--a precursor behavior to vocal imitation. Auditory-oral matching behavior by the infant was operationally defined as showing the mouth movement appropriate for producing the model sound just heard (mouth…

Investigated developmental change in symbolic representational ability by examining infants' imitation of vocalizations, words, visible motor actions, and nonvisible motor behaviors at ages 10, 13, 17, and 21 months. Results revealed a pattern of increasing imitation, supporting the view that a domain-independent representational capacity develops…

This paper provides evidence for imitative abilities in neonatal chimpanzees ("Pan troglodytes"), our closest relatives. Two chimpanzees were reared from birth by their biological mothers. At less than 7 days of age the chimpanzees could discriminate between, and imitate, human facial gestures (tongue protrusion and mouth opening). By the time…

During an experiment on infant behavior, it was observed that young children shared toys with their mothers; therefore, a series of research studies was designed to investigate this phenomenon. The general purposes of the research were: (1) to define sharing more precisely and develop objective measures of frequency and duration for it, (2) to…
