Results supported the hypothesis that 12 year olds are more willing to lie for a peer who previously helped them than are 8 year old. (Author)

The prediction was confirmed that young children would experience more difficulty in learning to discriminate faces of another race than those of their own. Additional findings revealed that discrimination-learning performance with racial stimuli is related to a number of factors including developmental level, race of the subject, and race of the…

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.

Study failed to yield evidence that performance in a systematic-concept task can be significantly facilitated, in comparison with rote-task performance, if more time is allowed for the operation of what Metzger has called systematic concept formation. (Authors)

It was concluded that drawing rules are essential and that adequate visual analysis is a necessary but not sufficient prerequisite to the production of accurate copies. (Author)

The present paper called attention to the difference between discrimination among individuals and discrimination among groups and suggested that the intraclass correlation coefficient should be used in the process of item selection whenever one is interested in discrimination among groups.

Results of this study indicate that a model who gives verbal cues increases learning by retardates over both model-only and no-model treatments. However, a model only condition failed to differ from a no-model treatment. (Authors)

Conclusions from five experiments were: that the frequency of implicit associational responses has minimal effect on verbal-discrimination and two-category classification learning; and that the intrapair associations which do develop in verbal-discrimination learning are not critically involved in the making of those discriminations.

Research studies how visual information and redundancy contribute to letter and word identification. (Authors)

Study was designed as a further test of the effect of: induced muscle tension (IMT) on the efficiency of acquisition of verbal material; IMT during training on the retention of verbal material; and IMT during recall on the recall of verbal material. (Authors/CB)

Hypothesis of this study was that parents who see their child's behavior problems as outside of parental control will have a more external'' orientation than those parents who see their child's behavior problems as a consequence of their own behavior toward the child. (Authors/CB)

In examples of school handicraft design, such as the ones in this experiment, where an appropriate substitute medium is available modelling has advantages over drawing as a design technique. (Author/CB)

Experiments reported here confirm the finding that performance can actually improve as intradimensional variability increases. (Authors/MB)

Study explored the manner in which young children utilize meaning clues implicit in nonlinguistic aspects of context to aid comprehension of difficult sentences. (Editor)

In this study children between the ages of 3 and 6 years were each presented with six number problems in which length and density were varied according to the proposed composition rules. (Authors)
