The neural mechanisms of fear suppression most commonly are studied through the use of extinction, a behavioral procedure in which a feared stimulus (i.e., one previously paired with shock) is nonreinforced repeatedly, leading to a reduction or elimination of the fear response. Although extinction is perhaps the most convenient index of fear…

Dimensional preference tasks in both visual and haptic modalities with three dimensional stimuli varying in form, size, color, or texture were presented to 64 children. There were 16 subjects at each of four grade levels: preschool, kindergarten, grade 1, and grade 3. On each trial, the subject was presented three stimuli and asked to tell the…

The effect of dimensional training on the mode of response of kindergarten children to two-dimensional stimulus materials was investigated by Kruskal-Shepard scaling and Procrustes rotation procedures. Twenty-two kindergarten children were used as Ss. The stimuli consisted of five cardboard rectangles varying on two dimensions of colour and size.…

Six groups of nursery schoolers, kindergarteners, and first graders balanced for sex were trained and tested on a series of discrimination learning and transposition problems. (Author)

Studies based on an analysis of one species of learning and transfer task, the transposition problem, in terms of two ways in which the experimenter's and the child's definition may differ. (Author)

Results of two experiments show that only postinformative feedback intervals to be significant sources of variation; mean trends appeared to indicate that extended preresponse intervals interfere with performance, if anything. (Authors/MB)

A series of three experiments with nursery school children is reported using texture cues to investigate the relationship between cue differences and learning rate. (Authors/MB)

Data were discussed in terms of an outline of an empirically based theory of transfer. (Authors)
