The purpose of this research was to determine what effects, if any, widening or narrowing the response repertoire has on measures of IQ and problem solving of preschool children. It was predicted that response widening, or creative/divergent thinking, would have a positive effect on IQ and problem solving. Forty-one preschool children 3 to 6 years…

In a study of the effects of cannabis on cognitive functioning, several cognitive and psychomotor tests were administered to four groups of subjects. (Editor/RK)

An exploratory investigation of the relationship between serum uric acid levels in male university students and their scores on tests of convergent and divergent thinking was carried out. (Editor)

It was hypothesized that certain programmed productive thinking materials would increase both the divergent and convergent thinking abilities being measured and that there would be a direct relationship between any change in one of these abilities and any change in the other. Six classes of 6th-grade suburban students with I.Q.'s ranging from 79…

Results yielded three hierarchical factors, two that were moderately related to IQ and MA and one that was independent of IQ and MA. Explanation of the findings was based on a consideration of the differences between divergent and convergent production abilities. (Author)

This study examined the relationship between convergent and divergent thinking and performance errors in reversal and nonreversal concept tasks. The results show: (1) a positive relationship between convergent performance and concept errors; and (2) an inverse relationship between divergent performance and concept errors. These correlational…

Presented is a reinterpretation of aphasia in relation to the divergent and convergent components of the model of behavior proposed by J. Guilford. (Author/IM)

The cognition theories of Piaget as they apply to adults are examined in the light of new theories about the characteristics of formal reasoning abilities and their acquisition over a long life span. (JD)

A study examining the performance of college freshmen trained in thinking skills and the relationship of this training to scores on an intelligence scale indicates that groups taught divergent thinking skills scored significantly higher in a comprehension subtest than did groups taught convergent thinking skills or the control group.

Eighty preschoolers participated in a study of the usefulness of the lure-retrieval paradigm. Four treatment conditions were compared: In addition to play and training conditions, a questions condition and an alternative-materials control group were employed. Results prompted discussion of theoretical and methodological issues surrounding the…

Discusses some critical aspects of divergent and convergent thinking, examining attributes of the public school environment that apparently foster convergent thinking and addressing the microcomputer's potential as an instrument for fostering divergent cognitive styles. (MP)
