Oculomotor Exploration of Impossible Figures in Early Infancy
Peer reviewed Peer reviewed
Direct linkDirect link
Shuwairi, Sarah M.; Johnson, Scott P. – Infancy, 2013
Previous studies have revealed that young infants can distinguish between displays of possible or impossible figures, which may require detection of inconsistent depth relations among local line junctions that disrupt global object configurations. Here, we used an eye-tracking paradigm to record eye movements in young infants during an object…

Jeste, Shafali S.; Kirkham, Natasha; Senturk, Damla; Hasenstab, Kyle; Sugar, Catherine; Kupelian, Chloe; Baker, Elizabeth; Sanders, Andrew J.; Shimizu, Christina; Norona, Amanda; Paparella, Tanya; Freeman, Stephanny F. N.; Johnson, Scott P. – Developmental Science, 2015
Statistical learning is characterized by detection of regularities in one's environment without an awareness or intention to learn, and it may play a critical role in language and social behavior. Accordingly, in this study we investigated the electrophysiological correlates of visual statistical learning in young children with autism…

Abstract Rule Learning for Visual Sequences in 8- and 11-Month-Olds
Peer reviewed Peer reviewed
Direct linkDirect link
Johnson, Scott P.; Fernandes, Keith J.; Frank, Michael C.; Kirkham, Natasha; Marcus, Gary; Rabagliati, Hugh; Slemmer, Jonathan A. – Infancy, 2009
The experiments reported here investigated the development of a fundamental component of cognition: to recognize and generalize abstract relations. Infants were presented with simple rule-governed patterned sequences of visual shapes (ABB, AAB, and ABA) that could be discriminated from differences in the position of the repeated element (late,…

Infants' Response to Pictures of Impossible Objects
Peer reviewed Peer reviewed
Direct linkDirect link
Shuwairi, Sarah M.; Tran, Annie; DeLoache, Judy S.; Johnson, Scott P. – Infancy, 2010
Previous work has shown that 4-month-olds can discriminate between two-dimensional (2D) depictions of structurally possible and impossible objects [S. M. Shuwairi (2009), "Journal of Experimental Child Psychology", 104, 115; S. M. Shuwairi, M. K. Albert, & S. P. Johnson (2007), "Psychological Science", 18, 303]. Here, we asked whether evidence of…

Development of Visual Selection in 3- to 9-Month-Olds: Evidence from Saccades to Previously Ignored Locations
Peer reviewed Peer reviewed
Direct linkDirect link
Amso, Dima; Johnson, Scott P. – Infancy, 2008
We examined changes in the efficiency of visual selection over the first postnatal year with an adapted version of a "spatial negative priming" paradigm. In this task, when a previously ignored location becomes the target to be selected, responses to it are impaired, providing a measure of visual selection. Oculomotor latencies to target selection…

Perception of Object Unity in Young Infants: The Roles of Motion, Depth, and Orientation.
Peer reviewed Peer reviewed
Johnson, Scott P.; Aslin, Richard N. – Cognitive Development, 1996
Two experiments examined the effects of common motion, background texture, and orientation on four-month olds' perception of unity of a partially occluded rod. Results indicated that infants' perception of object unity is not dependent on a single visual cue but on a variety of cues including motion, interposition, depth cues, background texture,…
