Peer reviewedXu, Fei; Spelke, Elizabeth S. – Cognition, 2000
Two experiments examined 6-month-olds' ability to discriminate between visual displays of various number of dots varying in size and position, and with controls for other extraneous variables. Findings indicated that infants could discriminate between large sets on the basis of numerosity if they differed by a large ratio (8 versus 16, but not 8…

Serial habituation of visual fixations was investigated through a design permitting cross-sectional, within-subject longitudinal, cohort longitudinal, and time-lag analyses. Results suggested that for all ages habituation was under way to the parts of the stimulus in order of the realitive saliencies. No one methodology appeared to significantly…

Newborns were habituated to white squares of varying size and luminance and retested with colored squares for recovery of habituation. Newborns could discriminate yellow-green from white in large squares, but not in small squares. They could not discriminate blue, blue-green, or purple from white. Results suggest newborns have little…

Peer reviewedAdams, Russell J.; Courage, Mary L. – Journal of Experimental Child Psychology, 1998
Habituated 180 neonates to white lights of varying luminance and tested for recovery of habituation to green, yellow, or red lights varying in excitation purity. Found that newborns discriminated chromatic stimuli from white only when excitation purity exceeded levels much higher than those for adults. Results reinforce view that neonates' vision…

This study examines serial habituation in a sample of 54 infants aged 2, 3, and 4 months to determine whether age changes are partially a function of different "strategies" rather than simply different rates of habituation. The serial habituation hypothesis proposes that attention and habituation of attention proceed in order of the relative…

Object Recognition and Attention to Object Components by Preschool Children and 4-Month-Old Infants.
Peer reviewedHaaf, 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…
