Several samples of black and white students were drawn from the 1970 PSAT administration in Georgia and studies for item x race interaction on both the verbal and mathematical sections of the test. (Authors)

Results confirm an earlier finding that experimentally induced rehearsal facilitates recall. (Authors/CS)

It is concluded that attentional capacity is independent of intelligence, and that critical changes in this capacity may occur between ages 8 and 9. (Authors)

Previous studies have shown that retesting of groups of subnormal pupils does not lead to significant increases in the mean IQ; this present study confirms this for non-immigrant pupils. In contrast, however, there is a significant rise in the mean IQ of a group of immigrants. (Author)

The performance of the older subjects (10 years and up) was facilitated by the organizational cues, whereas that of younger subjects was not. (Author)

Results of the present study confirm the importance of the contingency variable in experiments dealing with the effect of supportive comment upon children's performance. (Author)

Several skills important to successful learning by discovery were found to be less essential to successful learning by rule. Results also supported the hypothesis that the outcome of discovery is the structural integration of previously known concepts, while the outcome of rule learning is the addition of new structure.

These results suggest that, for the purpose of measuring children's incidental learning, materials with integrated components such as color and shape are functionally different from stimuli with spatially independent components. (Authors)

Results demonstrate that the relationship between the structure of positive and negative instances within a learning series is also critical to concept learning when the concepts are presented in a nondimensioned way. (Authors/CB)

Results indicate that responses are not organized per se, but that response grouping is mediated by stimulus categories. (Author)
