Infants five- and seven-months-old were sequentially shown three stimulus arrays of visual elements, only one of which was capable of producing subjective contours. An infant habituation control procedure was used to test infants' abilities to discriminate the arrays. (Author/RH)

The perceived spatiotemporal continuity of objects depends on the way they appear and disappear as they move in the spatial layout. This study investigated whether infants' predictive tracking of a briefly occluded object is sensitive to the manner by which the object disappears and reappears. Five-, 7-, and 9-month-old infants were shown a ball…

Assessed 13- and 20-week-olds infants' discrimination between shearing stimuli, in which columns of dots move vertically on a screen at different velocities, and foil stimuli, in which all dots move at the same velocity. Results revealed the threshold levels of dot velocity in shearing stimuli at which discrimination occurred. (BC)
