A linked perceptual class consists of two distinct perceptual classes, A' and B', the members of which have become related to each other. For example, a linked perceptual class might be composed of many pictures of a woman (one perceptual class) and the sounds of that woman's voice (the other perceptual class). In this case, any sound of the…

This study tested the assimilation of an auditory-visual stimulus configuration in 32 infants aged 15 to 16 weeks. The infants' discrimination of matched and mismatched auditory-visual stimuli indicated that infants by 4 months of age are capable of constructing bimodal schemata. (JMB)

A version of the paper was presented at the American Association on Mental Deficiency (Boston, May, 1968). (JM)

Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

Two 4-year-old children were shown the use of an apparatus whereby they could obtain toys and candy by making certain responses. The apparatus was a matching-to-sample device on which were arranged five response buttons in a circle and one in the middle. Each response button had a display window for the stimulus. Four of the five windows on the…

Preschoolers learned colors more rapidly than sizes and forms when cup stimuli were used. They learned sizes and forms more rapidly than colors when face stimuli were used. (RL)

The purpose of the two experiments was to assess the effects of two levels of stimulus redundancy and three levels of irrelevant visual stimulation on performance in a successive discrimination task and a reproduction task. The results indicate that increases in redundancy facilitated performance in the reproduction task but had no appreciable…

Human recognition behavior is influenced by the phenomenon of shape constancy, which occurs when the shape of an object is correctly perceived regardless of the orientation of the object in space. The research reported here tests the validity of the shape-slant invariance hypothesis, a theoretical formulation of the phenomenon of shape constancy.…

The information processing terms "content" and "address" are used to describe structural differences between the constructs of individual identity and identity in the equivalence sense. In both cases a sameness relation is established in spite of specific differences. The resulting constructs of identity are known to be…

Investigation indicates that perceptual inadequacy must be controlled in studies that utilize ambiguous, novel or nonsense designs in stimulus materials. (Authors)

This study was designed to investigate the effects of modeling or training with and without rule provision on the employment of strategies in solving four-dimensional, discrimination-learning problems. Subjects were 144 second and sixth-grade children from the New York City Public Schools. The blank-trial hypothesis testing paradigm was used. The…

This study was designed to examine the effects of age and sex on susceptibility to field dependence training and to determine whether the field dependence phenomenon is a function of cognitive style or of a general inability to make correct judgments because of confusing and inaccurate information. (MS)

Two experiments studied the influence of an individual's cognitive style on concept identification. Subjects were high school males, classified into levels of cognitive style according to their performance on the Hidden Figures Test. For the first experiment, three non-overlapping groups of 30 each were required to classify figural patterns, which…
