The development of pointing perception in infancy: effects of communicative signals on covert shifts of attention.
The present study aims to investigate the interplay of verbal and nonverbal communication with respect to infants' perception of pointing gestures. Infants were presented with still images of pointing hands (cue) in combination with an acoustic stimulus. The communicative content of this acoustic stimulus was varied from being human and communicative to artificial. Saccadic reaction times (SRTs...
متن کاملDifferential sensitivity to human communication in dogs, wolves, and human infants.
Ten-month-old infants persistently search for a hidden object at its initial hiding place even after observing it being hidden at another location. Recent evidence suggests that communicative cues from the experimenter contribute to the emergence of this perseverative search error. We replicated these results with dogs (Canis familiaris), who also commit more search errors in ostensive-communic...
متن کاملReasoning about instrumental and communicative agency in human infancy.
Theoretical rationality and practical rationality are, respectively, properties of an individual's belief system and decision system. While reasoning about instrumental actions complies with practical rationality, understanding communicative actions complies with the principle of relevance. Section 2 reviews the evidence showing that young infants can reason about an agent's instrumental action...
متن کاملBreed Differences in Domestic Dogs' (Canis familiaris) Comprehension of Human Communicative Signals
Recent research suggests that some human-like social skills evolved in dogs (Canis familiaris) during domestication as an incidental by-product of selection for “tame” forms of behavior. It is still possible, however, that the social skills of certain dog breeds came under direct selection that led to further increases in social problem solving ability. To test this hypothesis, different breeds...
متن کاملDogs' Gaze Following Is Tuned to Human Communicative Signals
Recent evidence suggests that preverbal infants' gaze following can be triggered only if an actor's head turn is preceded by the expression of communicative intent [1]. Such connectedness between ostensive and referential signals may be uniquely human, enabling infants to effectively respond to referential communication directed to them. In the light of increasing evidence of dogs' social commu...
متن کاملCommunicative Signaling Activates ‘Broca's’ Homolog in Chimpanzees
Broca's area, a cerebral cortical area located in the inferior frontal gyrus (IFG) of the human brain, has been identified as one of several critical regions associated with the motor planning and execution of language. Anatomically, Broca's area is most often larger in the left hemisphere, and functional imaging studies in humans indicate significant left-lateralized patterns of activation dur...
