Object Processing in Visual Perception and Action in Children and Adults
Peer reviewed Peer reviewed

Schum, Nina; Franz, Volker H.; Jovanovic, Bianca; Schwarzer, Gudrun – Journal of Experimental Child Psychology, 2012
We investigated whether 6- and 7-year-olds and 9- and 10-year-olds, as well as adults, process object dimensions independent of or in interaction with one another in a perception and action task by adapting Ganel and Goodale's method for testing adults ("Nature", 2003, Vol. 426, pp. 664-667). In addition, we aimed to confirm Ganel and Goodale's…

The Development of Perceptual Grouping Biases in Infancy: A Japanese-English Cross-Linguistic Study
Peer reviewed Peer reviewed
Direct linkDirect link
Yoshida, Katherine A.; Iversen, John R.; Patel, Aniruddh D.; Mazuka, Reiko; Nito, Hiromi; Gervain, Judit; Werker, Janet F. – Cognition, 2010
Perceptual grouping has traditionally been thought to be governed by innate, universal principles. However, recent work has found differences in Japanese and English speakers' non-linguistic perceptual grouping, implicating language in non-linguistic perceptual processes (Iversen, Patel, & Ohgushi, 2008). Two experiments test Japanese- and…

The Effect of Occlusion on Motion Integration in Infants
Peer reviewed Peer reviewed
Direct linkDirect link
Otsuka, Yumiko; Konishi, Yukuo; Kanazawa, So; Yamaguchi, Masami K. – Journal of Experimental Psychology: Human Perception and Performance, 2009
Previous psychophysical studies have shown that the adult human visual system makes use of form information such as occlusion to determine whether to integrate or segregate local motion signals (J. McDermott, Y. Weiss, & E. H. Adelson, 2001). Using the displays developed by McDermott et al., these experiments examined whether occlusion and amodal…

Out of Sight Is Not out of Mind: Developmental Changes in Infants' Understanding of Visual Perception during the Second Year
Peer reviewed Peer reviewed
Direct linkDirect link
Poulin-Dubois, Diane; Sodian, Beate; Metz, Ulrike; Tilden, Joanne; Schoeppner, Barbara – Journal of Cognition and Development, 2007
Three experiments investigated 14-, 18-, and 24- month-old infants' understanding of visual perception. Infants viewed films in which a protagonist was either able to view the location of a hidden object (Visual Access condition) or was blindfolded when the object location was revealed (No Visual Access condition). When requested to find the…

Motion Popout in Selective Visual Orienting at 4.5 but Not at 2 Months in Human Infants
Peer reviewed Peer reviewed
Direct linkDirect link
Dannemiller, James L. – Infancy, 2005
The effect of element density on selective orienting was examined in 2 experiments with 2- and 4.5-month-old infants. Selective visual orienting to a singleton oscillating target that appeared with other static bars was used to study the effects of element density. Increasing the set size and density of the static bars decreased selective…

Object Recognition and Attention to Object Components by Preschool Children and 4-Month-Old Infants.
Peer reviewed Peer reviewed
Haaf, Robert A. – Journal of Experimental Child Psychology, 2003
This study investigated attention to and recognition of components in compound stimuli among infants and preschoolers. Oddity tasks with preschoolers and familiarization/novelty-preference tasks with infants demonstrated successful discrimination among stimuli components on basis of edge property information. Matching tasks with preschoolers and…
