Eye-trackers suitable for use with infants are now marketed by several commercial vendors. As eye-trackers become more prevalent in infancy research, there is the potential for users to be unaware of dangers lurking "under the hood" if they assume the eye-tracker introduces no errors in measuring infants' gaze. Moreover, the influx of voluminous…

Eye tracking offers a powerful research tool for developmental scientists. In this brief article, the author introduces the methodology and issues associated with its applications in developmental research, beginning with an overview of eye movements and eye-tracking technologies, followed by examples of how it is used to study the developing mind…

Cognitive categories in infants that have relevance for linguistic development were investigated. "Agent" and "recipient," the categories chosen, are relational categories which by definition involve action. This experiment explored infants' (48 males, 14-24 months of age) sensitivity to certain "action parameters" of events. The question of…

An experiment was performed to show that infants perceive auditory and visual stimuli within a common space and that they perceive the sound as an attribute of the visual object. Subjects were 22 infants aged 3 to 5 months. Each infant was presented with a toy that moved in a small arc from side to side of a small window at the rate of one arc per…

Papers and discussants' comments from a symposium on issues concerning infants' reactions to strangers are presented. Researchers agreed that there is a developmental shift in infant behavior at 7 to 9 months of age when the infant becomes more cautious in approaching strangers. However, investigators hypothesize that the presence of the mother,…

This study examined age differences in children's visual fixation and search strategies of two dimensional visual stimuli. The hypotheses tested were: (1) that no age differences exist in general search strategies regardless of stimuli position, (2) that age differences could be expected with respect to the number and duration of visual fixations,…

Research on reading has tried, and failed, to account for wide disparities in reading skill even among children taught by the same method. Why do some children learn to read easily and quickly while others, in the same classroom and taught by the same teacher, don't learn to read at all? In "Language Development and Learning to Read", Diane…
