Groups of second grade and college students were presented with a series of three-alternative, four-dimensional discrimination problems that contained probes for the subject's hypothesis. Subjects received either complete feedback or partial feedback. In the latter condition, when subjects were told their response choice was incorrect the correct…

Presents two experiments which examined: (1) the tendency to make differential cue-producing responses to the values of dimensions that vary within or between settings; and (2) the hypothesis that children have more experience with problems following a two-choice simultaneous discrimination format than a successive one. Subjects were third- and…

Color and form preferences of kindergarten, first and third grade Ss were tested using standard two-dimensional geometric forms. (Author)

In the course of two experiments, groups of kindergarten, second, fourth, sixth grade and college students received several discrimination problems to investigate hypothesis testing behavior. (Authors/MB)

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.…

Presolution reversal prevented or significantly retarded learning in kindergarten and first-grade children but did not hinder learning in fifth-grade children. (Authors)
