Presents research that tests the empirical validity of the construct of Central Conceptual Structure (SCC) proposed by R. Case to account for children's conceptual development in 3 distinct domains: number, space, and social cognition. Three batteries of tasks (numerical, spatial, and narrative) were translated and administered to 69 6–10 yr old French children. The experiment was designed to verify 3 hypotheses relative to the development of SCC: the 1st concerns developmental synchrony between the numerical, spatial and narrative SCC; the 2nd individual differences in the elaboration of SCC; and the 3rd, relation between treatment capacities and levels of conceptual structuring. Results show that the developmental synchrony postulated within SCC is not generalized to all domains and age levels; individual patterns of performance are mostly similar; and the positive correlations observed between span measures and battery scores are not sufficient to validate the relation between treatment capacities and conceptual structuring. The limits of the SCC construct both in characterizing cognition at different age levels and specifying children's reasoning in different domains of knowledge are discussed with regard to the role attributed by Case to the general capacity of treatment.

When taking multiple-choice tests of reading comprehension such as the Scholastic Assessment Test (SAT), test takers use a range of strategies that vary in the extent to which they emphasize reading the questions versus reading the passages. Researchers have challenged the construct validity of these tests because test takers can achieve better-than-chance performance even if they do not read the passages at all. By using an individual-differences approach that compares the relative power of working memory span to predict SAT performance for different test-taking strategies, the authors show that the SAT appears to be tapping reading comprehension processes as long as test takers engage in at least some reading of the passages themselves.

In this study, the authors evaluated the effects of a brief personal construct group therapy on breast cancer survivors (N = 42) randomly assigned to either the treatment or wait-list control condition. The Gottschalk Gleser Content Analysis Scales were used to measure the effects for group across time (preand posttreatment, pretreatment, and 3-month posttreatment) on the personal construct states of threat, threat to existence, dislocation, and hope. Analyses showed that the beneficial effects of therapy achieved posttreatment were maintained at 3-month follow-up. The therapeutic group factors (I. D. Yalom, 1995) identified by the therapy group members as helpful in achieving these outcomes are also reported. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
