Although there has been a considerable amount of research on simultaneous and successive processing (Luria's second functional unit) by Das and others, there have been relatively few investigations into the measurement of attention and planning (the first and third functional units, respectively). The purpose of this investigation was to examine the factorial validity of tasks designed to measure cognitive processing in each of Luria's three functional units. A sample of 112 normal fourth- and fifth-grade students were administered nine experimental tasks chosen or developed according to the theoretical components of planning, attention, simultaneous, and successive processes. Principal factor analyses (orthogonal and oblique) with rotation of four factors resulted in solutions that closely matched the anticipated groupings based on a structural analysis of the tasks. General support for the feasibility of measurement of Luria's cognitive processing model, and the need to further develop and refine these and other experimental tasks, was obtained. 相似文献

An investigation was conducted to examine how individuals choose situations in which to initiate relationships. It was hypothesized that individuals' self-monitoring orientation and the characteristics of their relationship partners would interact to determine situation choices. Accordingly, low- and high-self-monitoring men were asked to rate their preferences for interacting in romantic and nonromantic situations with particular types of partners. The characteristics of the partners were varied along two dimensions: physical attractiveness and personality desirability. Results demonstrated that low-, relative to high-, self-monitoring individuals' preferences for interacting in romantic situations were more influenced by the personality characteristics of potential partners. In contrast, high-, relative to low-, self-monitoring individuals' preferences for interacting in romantic situations were more influenced by the physical attractiveness of potential partners. Neither of these effects occurred when preferences for nonromantic situations were assessed. Implications of these differences for the initiation, maintenance, and dissolution of relationships were discussed. 相似文献

The purpose of this note is to formulate some weaker versions of the so called Ramsey test that do not entail the following unacceptable consequenceIf A and C are already accepted in K, then if A, then C is also accepted in K. and to show that these versions still lead to the same triviality result when combined with a preservation criterion. 相似文献

This study examined the assumption that the gender gap has narrowed over time in the writing of sexual graffiti from male and female bathrooms of five colleges and universities in 1972 and 1984. In both studies, female graffiti, in relation to male graffiti, made fewer sexual references. In addition, female graffiti were more socially acceptable in regard to langauge and content. Overall, these results suggest that the decade of the 1970s may have had little or no impact on the pattern of gender differences in the sexual content and social acceptability of wall writings.An earlier version of this paper was presented at the annual meeting of the Society for the Study of Social Problems, August 26, 1985. 相似文献

This is a report of the completion responses for 40 three-letter word stems (e.g., ABO) produced by 100 undergraduate students at the University of California at San Diego. The report includes a list of the different words that were written as stem completions, their frequency of occurrence as completions, and their frequency of occurrence in English according to published norms. This list of materials is useful for the construction of completion tests for future investigations of direct priming phenomena, and it may provide an important covariate in the analysis of performance on completion tests. Preliminary analyses of the results reveal three primary factors that determine overall performance on a stem-completion test: word frequency, word length, and meanings per word. Analyses of the completions produced for each individual word stem, however, reveal that usually only one of these factors makes a significant contribution to performance. 相似文献
