This research deals with individual differences in the ability to focus and divide attention. Eighty-five subjects performed visual search and auditory detection tasks in three conditions: single channel, focused attention, and divided attention. Reaction time (RT) was fastest in the single channel condition, intermediate in the focused attention condition, and longest in the divided attention condition, and these effects were much stronger in the auditory than the visual task. Correlations among RTs in the three conditions were very high within modality (>.88), and lower between modalities (.5 to .6). The correlational data was well fit by a model that included separate factors for the visual and auditory tasks. Measures from the three attentional conditions within each modality loaded equally on these factors. The data provided no evidence for distinct abilities to divide or focus attention. 相似文献

Selected attitudinal and value characteristics of high and low successful consultants were considered. Twelve consultants and 15 consultees completed six measures. Consultants were categorized as high or low success consultants based on the coding of consultants' logs. Results indicate high and low success consultants do not differ on the selected characteristics. Also, the results indicate that more successful consultants have consultees who are more authoritarian and dogmatic and are more dissimilar to their consultees in level of dogmatism and reported need for assistance. Future investigations will indicate whether the results can be replicated on a more representative consultee sample. 相似文献

This study investigated the performance of 285 matched pairs of Black and White children from the standardization sample on the 12 subtests and 3 IQ scales of the Wechsler Intelligence Scale for Children—Revised (WISC-R). The children were matched on four demographic variables found in a previous (Reynolds and Gutkin, 1979) study to be significantly related to WISC-R performance: sex, socioeconomic status as determined by the occupation of the head of household, region of residence in the U.S. and urban vs rural residence. Multivariate analysis of variance comparing performance across race on the 15 dependent variables revealed that Whites exceeded Blacks on all tasks except Digit Span—a test of rote memory. Results were also related to the evaluation of the Spearman hypothesis. 相似文献

Following Lopata's (1966) model of the life cycle of the married woman's role, it was predicted and found that a woman's life stage would be related to her role pressures (work, home, self, and time), conflict, and satisfaction. Age and number of roles were not as strongly related to these variables as was life stage. Work activities and pressures declined through the peak child-rearing stage and then increased for women with older children, while pressures from home generally rose throughout the life cycle. The differential impact of various sources of conflict in different life stages was reported, and forms of organizational career support oriented toward particular life stages were suggested. 相似文献

This study described the development of occupational decision processes over the high school years. Five developmental trends derived from theory were examined separately for males and females in three rural schools. Growth was defined as increased frequency in classes of behavior from early 9th grade to late 12th grade. The key processes in occupational decision development for both sexes appeared to be an information search strategy and an elaborate rationale. Both processes increased in complexity and contributed to confident feelings about occupational choices in 12th grade. Implications for measurement of occupational decision processes and for developmental research are discussed. 相似文献

In the Spring of 1973, the Office of Research and Development of the Appalachian Center, West Virginia University, began an evaluation of the University's mining extension program. Since all interested miners are allowed to enroll in the course, the only feasible way to obtain a control group was to use the “snowball process.” This paper examines how well the snowball process did in producing a control group which matched the trainees. While the trainees and controls seemed well matched on many demographic characteristics they differed on several variables, particularly attitudes. 相似文献

Prediction models employing multiple linear regression of raw scores, multiple linear regression of factor scores, the single best predictor, and a nine-point decision rule index were compared. The subjects were 296 clients undergoing vocational counseling and evaluation. Predictor variables included performance ratings, demographic variables, and WAIS subtest scores; the criterion was employment status upon program completion. The least statistically sophisticated model, employing the single best predictor, was the most successful approach. Considerable shrinkage in power of prediction was demonstrated upon cross-validation particularly for multiple linear regression of raw scores model, indicating the necessity of cross-validating prediction schemes. Additional suggestions are made to those designing prediction studies. 相似文献

Comparisons were made between the post high school plans and the adequacy of father identification of male adolescents from rural economically deprived areas. The subjects were divided into two groups, low identification males (LIM) and high identification males (HIM) based on independent evaluators' judgments of the adequacy of their fathers. Each group's responses to a questionnaire concerning future plans and aspirations were compared. In general, the hypotheses predicting that HIM subjects have higher levels of aspiration, more self-confidence and greater satisfaction with school experiences were confirmed by the data. 相似文献
