Three experiments demonstrate that the context of a two-object array greatly influences the way in which young children represent the array in their copies. Children were aware of differences in orientation and in the nature of paired objects and were concerned with marking these differences in their drawings. (RH)

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

Shows how the visual differential theory provides a model that illuminates the effects of visual manipulation on communication. Includes illustrations. (GT)

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

Four-month-old infants' stimulus preferences were assessed using an operant paradigm with mobile reinforcers of different colors (blue, green). (Author/MP)

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)

Investigates whether five-week-old infants' attention to a schematic face would increase as the velocity of its oscillating eye dots increases. Twenty-four infants served as subjects. (MP)

Forty-four college students rated six framed, black-and-white single object pictures to determine if the framing of an object or the field surrounding it gives it more meaning. Based on factor analysis of the results, recommendations are made for future research. (JEG)

A perceptual analogue of Kelley's augmentation principle was created in animated films depicting the movements of two objects toward a goal. Experiment 1 examined children's causal attributions in the presence and absence of inhibitory causes. Experiment 2 investigated children's causal attributions in the presence of inhibitory causes of…

In order to study infants' sensitivity to binocular information for depth, 11 infants, 20 to 26 weeks of age, were presented with real and stereoscopically projected virtual objects at three distances, and the infants' reaching behavior was videotaped. (Author/SB)

A theoretical interpretation of the stimulus familiarization effect was explored in three experiments with 6- through 7-year-old children. (Author/SB)

The reactions of 112 10-month-old male infants to the property of curvature were examined using a habituation paradigm with lever pressing as an instrumental response. (SB)

Examined visual fixation in 3- to 6-month olds for fit to attentional inertia theory. Found that look duration toward extended audiovisual stimuli had a lognormal distribution. The conditional probability of looking away decreased when look duration increased. Heart rate deceleration accompanied look onset and stimulus changes occurring within…

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.…
