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)

Data suggest an ability to use concrete-operational reasoning is not required for doing complex arithmetic, even though it may be necessary for learning these arithmetic skills. (Authors)

The time-series process postulated is a more general form of the integrated moving average model than for which estimation and testing procedures were formerly available. (Author)

Paper presents normative data on the Mathematics Anxiety Rating Scale (MARS), which measures anxiety associated with number manipulation or mathematics concepts. (Authors)
