It is urged that investigators lay aside demonstrations of the existence of mediation in young children as focus of research, substituting a search for the conditions of its occurrence. (Authors)

Replies to Gholson's commentary (PS 522 655) on the article by Coldren and Colombo in this monograph. Discusses limitations in the shift procedure methodology traditionally used in research on discrimination learning, and considers the use in future research of methodologies that can precisely decompose children's responses to feedback during…

This review argues that an hypothesis about longitudinal development may be derived from, and tested exclusively by, cross-sectional data, when the potential sources of interpretive errors are dealt with adequately. The argument is illustrated by cross-sectional data relevant to developmental mediation theory. (Author/SS)

This data on transfer and list identification, combined with those reported by Petrich et al. (1975), strongly suggest that the decision component is the major factor affecting the free recall of successive overlapping lists. This decision component is best described by Anderson and Bower's model (1972) of the roles of list tagging and contextual…

Compared two procedures for establishing and reversing stimulus control transfer across simple discrimination in children. Results indicated that both procedures were more effective in establishing that, in reversing stimulus control transfer, stimulus contiguity was more effective than match-to-sample training; and both procedures were more…

The contribution of decentration as an underlying component of discrimination learning and discrimination shift behavior was investigated in this study. In addition, the effect of verbal labeling and the relationship of academic achievement to discrimination learning and decentration was considered. The subjects were 120 first grade students who…
