San Juan, Valerie; Lin, Carol; Mackenzie, Heather; Curtin, Suzanne; Graham, Susan A. – Journal of Child Language, 2019
We examined if and when English-learning 17-month-olds would accommodate Japanese forms as labels for novel objects. In Experiment 1, infants (n = 22) who were habituated to Japanese word-object pairs looked longer at switched test pairs than familiar test pairs, suggesting that they had mapped Japanese word forms to objects. In Experiments 2 (n =…

Rakison, David H.; Krogh, Lauren – Developmental Science, 2012
Previous research has established that infants are unable to perceive causality until 6 1/4 months of age. The current experiments examined whether infants' ability to engage in causal action could facilitate causal perception prior to this age. In Experiment 1, 4 1/2-month-olds were randomly assigned to engage in causal action experience via…

Brannon, Elizabeth M.; Suanda, Sumarga; Libertus, Klaus – Developmental Science, 2007
Time perception is important for many aspects of human behavior, and a large literature documents that adults represent intervals and that their ability to discriminate temporal intervals is ratio dependent. Here we replicate a recent study by vanMarle and Wynn (2006 ) that used the visual habituation paradigm and demonstrated that temporal…

Moore, David S.; Spence, Melanie J.; Katz, Gary S. – Developmental Psychology, 1997
Two experiments examined 6-month olds' ability to categorize natural infant-directed utterances. Infants heard seven different tokens from one class of utterance (comforting, approving). Findings indicated that infants who later heard a test stimulus from the unfamiliar class showed response recovery, whereas those who heard a novel stimulus from…

Kellman, Philip J.; Arterberry, Martha E. – 1998
In the past 25 years, there has been an explosion in research on the development of perception. The research has produced discoveries at multiple levels: ecological analyses, models of representation and process, and improved understanding of biological mechanisms. This book provides a comprehensive treatment of infant perception, bringing…

Johnson, Scott P.; Aslin, Richard N. – Developmental Psychology, 1995
Examined perception of object unity in partial occlusion in 72 infants. Recorded how long subjects looked at a display of complete and incomplete rods. In test and control conditions, infants looked longer at broken rods than at complete rods, suggesting that infants' cognitive, visual, or attentional skills may be insufficient to support…
