Infants' apparent failure in gaze-following tasks is often interpreted as a sign of lack of understanding the referential nature of looking. In the present study, 8- and 12-month-old infants followed the gaze of a model to one of two locations hidden from their view by occluders. When the occluders were removed, an object was revealed either at…

Chimpanzees ("Pan troglodytes") and bonobos ("Pan paniscus") (Study 1) and 18- and 24-month-old human children (Study 2) participated in a novel communicative task. A human experimenter (E) hid food or a toy in one of two opaque containers before gesturing towards the reward's location in one of two ways. In the Informing condition, she attempted…

Twenty-four- and 30-month-old children were presented with a picture that showed the location of a hidden toy and were then asked to find the toy. The 30-month olds, but not the 24-month-olds, were successful in retrieving the toy. Concludes that 24-month olds did not interpret the pictures as representations of reality. (BC)

In two experiments on very young children's response to the orientation of pictures and objects, 18-, 24- and 30-month-old children showed no preference for upright pictures over inverted ones. More importantly, we found that children in all three age groups were equally accurate and equally fast at identifying depicted objects regardless of…

Two studies tested whether 12- and 24-month olds' self-knowledge differed from their knowledge of others (mother or inanimate object), or whether toddlers' knowledge of persons (self and mother) differed from knowledge of objects. Results showed that 12-month olds were more sensitive than older toddlers to perceptual features of objects. Data were…

Examined event-based memory in three groups of children between ages 14 and 25 months. Found that search task success was general in oldest group while performance was similar on a task in which success "may" have been due to recalling an object-removal event and one in which success could "only" have been due to recall of…

Research on children's understanding of video has shown seeming contradictions. Fourteen-month-olds imitate actions seen on TV (Meltzoff, 1988) and 18-month-olds are reminded of an event by watching video (Sheffield & Hudson, 2003) but 24-month-olds fail at a video-mediated object-retrieval task requiring dual representational understanding…

Infants follow the gaze direction of others from the middle of the first year of life. In attempting to determine how infants understand the looking behavior of adults, a number of recent studies have blocked the adult's line of sight in some way (e.g. with a blindfold or with a barrier). In contrast, in the current studies an adult looked behind…
