Lourenco, Stella F.; Huttenlocher, Janellen – Cognition, 2006
Previous studies show that following disorientation children use the geometry of an enclosed space to locate an object hidden in one of the corners [e.g. (Harmer, L., & Spelke, E. (1996). Modularity and development: A case of spatial reorientation. "Cognition, 61," 195-232)]. These studies have used a disorientation procedure that involves…

Jusczyk, Peter W.; Johnson, Scott P.; Kennedy, Lori J.; Spelke, Elizabeth S. – Cognition, 1999
This study compared role of motion in adults' and infants' perception of object unity. Findings favored ecologically-oriented accounts of object perception. Motion was a determinant of object unity for infants. Alignment and common motion contributed to adults' object-unity perception; synchronous color changes did not. Infants detected…

Wilcox, Teresa – Cognition, 1999
Four experiments examined the perceptual features used by 4.5- to 11.5-month olds to individuate objects involved in occlusion events. Results indicated that 4.5-month olds used shape and size features to individuate objects in occlusion events. By 7.5 months, infants used pattern, and by 11.5 months, they used color to reason about object…

Chiang, Wen-Chi; Wynn, Karen – Cognition, 2000
Four experiments examined 8-month-olds' ability to reason about collections of objects. Findings suggested that infants' expectations about object behavior do not automatically apply to any and all portions of matter within the visual field. The behavior of an entity and infants' prior experience played roles in determining whether infants will…

Gilmore, Rick O.; Johnson, Mark H. – Cognition, 1997
Investigated the nature of spatial representations underlying simple visually guided actions with 3- and 7-month-old infants. Saccades in older infants were executed within body-centered spatial coordinates that account for intervening eye movements, whereas younger infants responded according to the target's retinocentric locations without…

Senju, Atsushi; Yaguchi, Kiyoshi; Tojo, Yoshikuni; Hasegawa, Toshikazu – Cognition, 2003
A visual oddball paradigm was used to investigate whether children with high functioning autism had difficulty detecting mutual gaze under experimental conditions. Findings revealed that children with autism were no better at detecting direct gaze than at detecting averted gaze, unlike normal children. Findings suggest that the lack of ability to…

Wang, Ranxiao Frances – Cognition, 2004
Studies have shown that perception of distance, orientation and size can be dissociated from action tasks. The action system seems to possess more veridical, unbiased information than the perceptual/verbal system. The current study examines the nature of the distinction between action and verbal responses in a spatial reasoning task. Participants…

Ninio, Anat – Cognition, 1979
Piaget's theory of space perception is presented in the format of a hypothetico-deductive system. Eleven hypotheses regarding infants' space perception are defined, and Piaget's evidence for each is summarized. Presuppositions underlying the arguments are explicated. Critical notes are inserted and general conclusions are briefly discussed.…
