Preverbal infants can represent the causal structure of events, including distinguishing the agentive and receptive roles and categorizing entities according to stable causal dispositions. This study investigated how infants combine these 2 kinds of causal inference. In Experiments 1 and 2, 9.5-month-olds used the position of a human hand or a…

Two experiments investigated whether 5-month olds would look longer at rotating "drawbridge" appearing to violate physical laws because they knew it was causally impossible. Findings indicated that infants' longer gaze at 180-degree rotations was due to simple perceptual preference for more motion, challenging Baillargeon's (1987) claim…

Feeding-Based Arousal Effects on Visual Recognition Memory in Early Infancy.
Peer reviewed Peer reviewed
Geva, Ronny; Gardner, Judith M.; Karmel, Bernard Z. – Developmental Psychology, 1999
Studied feeding-related arousal effects on a visual recognition paired-comparison task at newborn, 1, and 4 months of age. Found that newborns and 1-month olds shifted from a familiarity preference before feeding to a novelty preference after feeding. Control-group testing confirmed that shift was not due to increased stimulus exposure. By 4…
