Among third, fourth, and fifth graders tested, performance on embedded figures and leveling-sharpening tests correlated with performance on traditional items of class inclusion, suggesting that psychological differentiation is related to reasoning by class inclusion. However, age changes in differentiation do not account for age changes in class…

A counselor response category system for measuring counselor verbal behavior was developed. The resulting system had 17 mutually exclusive categories, with at least minimal face and content validity. In rating counselor response units, the category system resulted in high agreement levels between judges. Analysis led to a revised 14-category…

Discusses the importance of assessing the impact infertility has on couples/individuals and understanding the relevance of this impact in the context of psychological treatment. Infertility's negative impact can be minimized by therapeutic intervention. Three psychological-behavioral categories for couples are posited, with case studies. (Author)

Suggests making a chart with simplified explanations of the Dewey Decimal codes, to help young children find their way around the library. (SJL)

Describes five classifications of language usage (representatives, directives, expressives, commissives, and declarations). Suggests that teaching reading comprehension is a matter of helping children understand these uses of language. (RL)

Five problems involved in the task of presenting a number of different education systems in statistical terms that are meaningful and useful to educational researchers, planners, and laymen are discussed. They include developing a classification system and conversion guides, providing a framework for updating work, and coordination among…

The personality typologies of couples who sought marital counseling were generally incongruent as determined by Holland codes. The Holland hexagonal model was useful in predicting which spouse would initiate marriage counseling, in obtaining a cognitive understanding of specific conflicts, and in helping couples resolve concerns.

Classification equations from birth certificate information accurately identified approximately 80 percent of the first-grade children who scored one standard deviation or more below the mean on both a measure of intellectual competence and a measure of adaptive behavior. (Author)

Personal adjustment was not found to be related to sex-role category. The inability to demonstrate a relationship between maladjustment and the Personality Research Form typology raised the question whether sex-role affiliation is largely independent of factors regarded as suggestive of poor mental health. (Author)

Suggests the designation of overlapping hierarchies in thesauri, first outlined in 1973, as a key element in progress towards a successful man-machine partnership. Article updates, expands, and provides theoretical background of 1973 proposal; postulates use of the UDC; and suggests means of distinguishing overlapping terms from other…

Robust interference effects were found which declined with age. Manipulating discriminability of the relevant stimulus dimension resulted in large changes in sorting time, but interference effects did not vary with baseline difficulty. These results were interpreted as strongly supporting both an absolute decrement model and a developmental trend…

Explored the development of hierarchical classification and the age at which this ability appears fully developed. Two measures of hierarchical classification ability were administered to primary, elementary, junior high and high school students. Discusses results which support Piaget's contention that this ability is not developed until late…

Two major periods of development in proportional reasoning are identified by analysis of a 23-item experiment given to subjects between 6 and 16 years of age. (MP)

Presents a method to improve client classification. Reviews clinical prediction models and statistical prediction issues. In classifying clients for remedial services, utility of the prediction scheme depends on gains accrued by its use over program base rates and relative cost. This assumes that differential treatments parallel diagnostic…

Two implications of best-example theory for category acquisition were tested using a set of artificial concrete object categories. Categories acquired from initial exposure to good exemplars were learned more easily and accurately. People learn the best exemplars are category members before learning the poor exemplars are category members.…
