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…

Reports on four experiments on pattern perception in four-month-old infants. The first experiment examined preference for patterns varying in structure; the second examined encoding patterns from different subset sizes; and the last two experiments examined changes in the size, position, and orientation of the habituation pattern.

This study explores the reason why very young infants are unable to respond differentially to faces and the cause for developmental changes in infant face perception by age 3 months. Linear systems analysis (LSA) and the contrast sensitivity function (CSF) were used to estimate the facial pattern information available to 1- and 3-month-old…

Children from 4 to 7 years of age were tested in a structured perceptual task in which haptic manipulation was available, but not required. The extent of haptic involvement with the stimulus material and its effect on performance in a perceptual recognition task was then determined. (Author/CB)

The processing of mental structures in perception appears to be serial, in that viewers can fill in missing parts from an impoverished stimulus following a top down process. To investigate the effects of unfamiliarity, complexity, and legibility on object and layout perception of unfamiliar stimuli, ten subjects were shown one of four ribbon…

Study found that auditory experience has an indirect influence on rhythm perception, but auditory involvement during the task does not. (Authors/MB)

A model for sequencing tasks in the area of visual perception was developed. This paper reports an attempt to validate the structure of the model. The performance of 50 normal preschool children on a 47 item test was studied. The results obtained support the use of the model as a framework for developing visual perception tasks. (Author)

Visual recognition, navigation, tracking, and imagery are posited to involve some of the same types of representations and processes. The first part of this paper develops a theory of some of the shared types of representations and processing modules. The theory is developed in light of neurophysiological and neuroanatomical data from non-human…
