The influence of stimulus number and familiarity on judged duration were investigated. Results showed that the number of stimulus elements presented within a given interval affected its perceived duration, although the familiarity of those elements (as defined herein) did not. (Editor/RK)

Investigates the perceptual basis of metaphor by asking 5-, 7-, and 10-year-old children and adults to pair and discuss films of natural objects, both stationary and moving. Concludes that motion information makes metaphoric similarity relatively easy to perceive and influences the form of descriptive metaphors. (Author/CB)

Assesses preschoolers' and adults' relative ability to solve classification problems in which a similarity criterion is the only criterion appropriate for solution. Also investigates effects of the salience of individual dimensions on solution-relevant similarity classifications. (AS)

Forty-eight neonates were randomly assigned to view a moving stimulus either in the horizontal or the upright position, with or without added vestibular stimulation and with or without pacifier sucking. Results indicate that vestibular proprioceptive stimulation, provided horizontally or semi-vertically, significantly enhanced visual tracking.…

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…

Five developmental experiments examine the role of context in visual search. (Author/JH)

This research reexamined the hypothesis that recognition is a developmentally stable component of the memory system. Recognition performance was compared across age groups. Particular attention was paid to the role of response biases and perceptual skills in developmental increases in recognition performance. (Author/DB)

This study investigated whether object-picture discrepancy occurs because preschool children regard pictures as significates rather than as signifiers. Results indicated the children did not consistently respond to objects and their pictorial representations equivalently. (Author/DB)

The ability of young infants between the ages of 8 and 17 weeks to perceive outline shapes was investigated in nine experiments using an habituation paradigm. (JMB)

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)

Tested the ability of 3.5-month-old infants to detect audiovisual relations. Results demonstrated infants' visual recovery to changes in temporal synchrony of sight and sound and in composition of objects. Infants did not demonstrate visual recovery to changes in the relationship between pitch and color or shape. (BC)

Two experiments found that (1) by age 8 months infants perceived that leaning extends their effective reaching space to grasp objects; (2) by 10 months they perceived the effective limits of leaning and reaching; and (3) by 12 months they began to perceive how this space may be extended by a mechanical aid. (MDM)

Infants were tested at 5, 8, and 13 months of age for numerosity perception. Subjects observed displayed figures on a screen moving at constant speed with irregular trajectories and occasional occlusions. Results demonstrated that discrimination of units, and not of characteristic patterns, underlies numerosity perception. (BC)
