Previous visual and auditory lateralization studies have demonstrated that the languages of bilinguals are lateralized to the left hemisphere to the same extent as in monolingual controls (C. Soares & F. Grosjean, 1981, Perception and Psychophysics, 29, 599-604; C. Soares, 1982, Neuropsychologia, 20, 653-659). The present study tested the same group of Portuguese-English bilinguals and a group of English-speaking monolinguals on a series of concurrent activity, or time-sharing, tasks. Greater levels of disruption in finger tapping with the right hand than with the left hand occurred during the performance of those tasks which required overt speech production, and this for both bilinguals and monolinguals. As in the previous studies, there were no lateralization differences across the bilinguals' two languages or between bilinguals and monolinguals. Thus, further evidence for equal levels of left-hemisphere dominance for language in bilinguals and monolinguals was provided by the use of the concurrent activities paradigm. 相似文献

The present study sought to determine whether significant relationships exist between life value preferences and personality traits and to describe the nature of any relationships identified. Administered to 310 undergraduate and graduate students were the 16 PF personality inventory and a 55-item Life Values Inventory which assessed values governing life styles and orientations. A factor analysis of the Life Values Inventory resulted in the identification of 14 life values dimensions. Factor scores for these 14 dimensions were then employed in a canonical analysis and a factor analysis with the 16 PF scores. The canonical analysis yielded results significant at the .001 level. The factor analysis yielded 10 factors, many of which displayed shared common-factor variance between Life Values and 16 PF variables. The interpretation of that shared variance identified several personality correlates of life values that suggested causal and developmental interactions of some value in describing and explaining human behavior. 相似文献

The psychometric properties of the Wolpe-Lazarus Assertiveness Scale (WLAS) were evaluated with a sample of 100 male and 157 female psychiatric patients. There were no significant differences with regard to males and females for total WLAS scores. The WLAS seems to be internally consistent and has acceptable split-half and test-retest reliabilities. A factor analysis performed separately for males and females indicates that the 10 most prominent factors account for about 60% of the accumulated variance. The primary factor, shared by males and females, was labeled General Expressiveness. There was little evidence for the external validity of the WLAS when total scores were correlated with performance on a role play test. However, when WLAS factor scores were evaluated in light of role played performance, somewhat better evidence of the external validity of the WLAS was found in two of the factors for the females. 相似文献

The purpose of this experiment, carried out on 27 subjects with intense and circumscribed fears, was to test one main hypothesis and several subsidiary predictions. The prediction that a high-demand in vivo treatment condition produces desynchronous changes and a low-demand treatment condition synchronous changes, was supported by some inter-session findings but not by the intra-session findings. The clear linear relation between heart-rate and reported fear was confirmed, as was the rapid habituation of the heart-rate response to phobic stimulation.The fear-reactions and fear-reductions of psychiatric and non-psychiatric were indistinguishable. High heart-rate responders and low heart-rate responders showed similar patterns of improvement. The constrained laboratory ‘treatment’ procedure used in the experiment produced large and rapid reductions in fear. 相似文献

Children from five to eight years of age learned to discriminate between mirrorimage oblique lines more readily when cards bearing the obliques were presented vertically than when they were presented horizontally. The difference in performance between the vertical and horizontal planes could not be accounted for by differences in either the external visual context or the availability of asymmetrical body information (e.g., left vs right hand). The superiority of the vertical plane was attributed to the congruence of objective, bodily, and retinal vertical axes for the vertical, but not the horizontal plane, It was concluded, on this basis, that at least part of children's difficulty discriminating between mirror-image obliques is due to their difficulty establishing the internalized vertical axis necessary for the left-right spatial coding of the obliques. 相似文献

Two experiments examined the possible role of children's semantic knowledge and their ability to encode it in a cued-recall test. Performance of children aged 7, 10, and 13 was observed in encoding specificity tasks, which used homographs as the to-be-remembered words (TBRs).In Experiment I, children of all ages performed better when the output cue words prompted similar meanings to the input cues, than when output and input meanings were incompatible. In Experiment II, all children were required to recall identical items, but younger children, owing to lack of knowledge, were unable to encode pairs comprising input and TBR words incompatibly with output cues. In such circumstances, younger subjects outperformed older subjects. When input and output cues were incompatible for all ages, recall increased with age, possibly due to older childrens' using more effective retrieval strategies.The findings indicate that semantic encoding influenced recall performance at each age. This suggests that age differences in memory are due to differences in the amount of semantic knowledge a child possesses for encoding and cuing and not to capacity differences. 相似文献

Social comparison theory predicts that when the person is uncertain about the level of his ability, he may seek comparison information through competitive behavior. This derivation, however, has never been directly tested. An experiment is reported in which the level of the subject's uncertainty about his competence was manipulated and subsequent measures of his competitive motivation and behavior were obtained. The data indicate that higher levels of uncertainty do lead to higher levels of motivation and competition, but only under conditions that minimize threat to self-esteem. 相似文献
