Infants' ability to mentally track the orientation of an object during a hidden rotation was investigated (N = 28 in each experiment). A toy on a turntable was fully covered and then rotated 90°. When revealed, the toy had turned with the turntable (probable event), remained at its starting orientation (improbable event in Experiment 1), or…

Used event-related potentials to examine infants' ability to form representations of stimuli presented in a haptic modality and to then recognize these stimuli as familiar when the stimuli were subsequently presented in a visual modality. Found that in certain conditions infants encoded the haptically familiarized object, then transferred their…

Five experiments using the visual habitation paradigm with 158 infants demonstrated that these 10-month olds did not use property/kind information to establish representations of 2 numerically distinct objects, a finding that provided support for the object-first hypothesis. (SLD)

Visual behavior of infants was assessed with multiple discrimination tasks week to week from four to seven months of age. Task to task reliability was low, but attentional averages from week to week were reliable. Generally, infants with shorter fixations showed more novelty preferences, and infants' shift rate improved with age. (SKC)

In this study, 50 infants (15 to 18 months of age) were shown four different film sets in an effort to determine (1) whether infants can perceive action role reversals between an actor and recipient of the action when the direction of the action is ruled out as a cue and (2) whether infants consider only animate objects to be potential…

Examines the ability of infants to track and anticipate the final orientation of an object. Subjects were infants ranging from an average of four months to eight months old. Three experiments, with the last one as control, were carried out. Concludes that infants show some rudimentary mental rotation from four months of age. (MOK)
