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…

Two-year-olds discriminated two original training stimuli nearly perfectly, thereby showing that some form of controlling stimulus-response relation had been established. Most children's generalization gradients had little or no slope. Results are not consistent with earlier generalization data from young children. (RH)

A component selection measure developed by Hale and Morgan (1971) was used to determine children's tendency to exercise selective attention. This tendency was assessed at six different levels of training, ranging from undertraining to overtraining, and was examined at each of three ages--4 (N=116), 8 (N=216), and 12 (N=104). In the learning phase,…

This study was designed to assess the relative effectiveness of four components of pretraining on a subsequent simultaneous discrimination and reversal: (1) making same-different judgments about the two stimuli; (2) making a specific observing response to the critical feature of the stimuli; (3) simple familiarization with the stimuli; and (4)…

This study examines some variables that may affect two aspects of syntax in Head Start children; the use of descriptors and the use of complete sentences. Thirty-six children were assigned to six experimental conditions in a design which varied adult verbal modeling, feedback, and sex. Children given adult verbal modeling produced significantly…

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.

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…
