Reports three experiments in infant visual perception which studied the processes underlying infants' shifts of fixation from one object to another. (JMB)

Study tests 45 four-month-old infants for color constancy using a familiarization, paired-comparison paradigm. Infants tested with a change in illuminant correctly recognized the familiar color under some conditions and failed to do so under others. (Author/RWB)

The results offered little support for the hypothesis that teaching severely retarded learners to label stimuli would reduce the likelihood of stimulus overselectivity. (Author)

Several propositions deduced from the discrepancy hypothesis were tested with four-month-old infants using random shapes in a habituation/discrepancy paradigm. (JMB)

Reports three experiments which investigated the discrimination of simple visual arrangements by three-month-old infants. An operant high-amplitude sucking technique was used in a stimulus familiarization-novelty paradigm. (JMB)

Three experiments explored effects of stimulus and task factors on tendency to categorize according to taxonomic relations when those relations conflict with appearances. When provided with information that constrained categorization, preschoolers and adults reliably based their decisions on taxonomic relations between physically dissimilar items.…

Three experiments using the familiarization-novelty preference procedure confirmed the hypothesis that three-month-old infants could form categorical representations of spatial relations above and below. The infants, after being shown a familiarization diagram with a dot appearing in multiple locations below a line, showed a preference for a novel…

The authors studied the influence of canonical orientation on visual search for object orientation. Displays consisted of pictures of animals whose axis of elongation was either vertical or tilted in their canonical orientation. Target orientation could be either congruent or incongruent with the object's canonical orientation. In Experiment 1,…

The use of multiple familiar views of objects to facilitate recognition of novel views has been addressed in a number of behavioral studies, but the results have not been conclusive. The present study was a comprehensive examination of view combination for different types of novel views (internal or external to the studied views) and different…

Stimulus over-selectivity is a phenomenon displayed by individuals with autism, and has been implicated as a basis for many autistic-spectrum symptoms. In four experiments, non-autistic adult participants were required to learn a simple discrimination using picture cards, and then were tested for the emergence of stimulus over-selectivity, both…

Three experiments were conducted to investigate the role of object representations in object substitution masking (OSM). OSM occurs when a very sparse mask is presented simultaneously with a target stimulus and the target offsets first, leaving the mask to linger in the display for some time. Results confirm earlier claims that there is an…

Elementary school students and adults were presented with a paired comparison task of visual complexity in which contour and presence or absence of structure in the patterns were manipulated. Results indicated that complexity judgments of all subjects were affected by the presence of structure at lower levels of contour. (GO)

This study investigated 17-week-old infants' response to discrepancy in visual patterns as a function of rate of habituation. (BRT)

In three experiments, the effect of additional "contextual" elements on the discrimination of the orientation of linear and curvilinear segments was investigated with four-month-old infants. Results suggest that, regarding certain stimuli and techniques of measurement, surrounding contextual segments can aid the discrimination of linear…
