Previous studies have provided evidence for subvocal rehearsal (inner voice) and phonological storage (inner ear) in auditory-verbal imagery. The question remains to be answered whether the inner voice mainly involves higher-order language systems, or primarily relies on motor systems associated with articulatory-kinesthetic processing. On the basis of models of auditory imagery and working memory, we predicted that, if auditory-verbal imagery is a form of motor imagery, performance on a novel auditory-verbal imagery task would be affected by concurrent articulatory suppression as well as by concurrent finger tapping. In contrast, we predicted that performance on a visuospatial control task would be significantly affected by concurrent tapping only. The auditory imagery task consisted of indicating, for bisyllabic words, the syllable that carried the stress. A significant interaction was observed between task (verbal vs. visual) and type of interference (articulatory suppression vs. tapping). Tapping affected reaction times on the visual task significantly more than articulatory suppression. However, both interference conditions affected the verbal task to an equal extent. The present findings confirm the role of subvocalization in auditory-verbal imagery and provide evidence for a strong involvement of articulatory-kinesthetic motor processing. 相似文献

The hypothesis of global precedence was investigated by manipulating the similarity between target and relevant level, and between target and global and local levels of hierarchical stimuli, both in divided and selective attention conditions. The similarity was measured on the basis of the amount of shared contour between two visual forms. The stimuli were circles, right-facing semicircles, i.e., 1/2 of the circumference missing, and right-facing partial circles with a 1/4 of the circumference missing. The circle was used as a target and, consequently, the similarity between target and semicircle and between it and the partial circle was 50% and 75%, respectively. In the divided attention condition, the results showed a local advantage in the two similarity conditions between target and distractor level (50% and 75%) and a bidirectional and symmetrical interference at both levels of similarity. However, in the 'selective attention condition', a local reaction time advantage was only found when the similarity between target and irrelevant level was of 50%. When attention was directed towards the global level, local interference increased depending on the decrease in the degree of the local level similarity. When the attention was directed towards the local level, there was global interference but it was independent of the degree of the global level similarity. These results show the importance of the physical shape of the local elements used in experiments with hierarchical stimuli, since they may determine the relative speed of global processing, facilitating or impairing it. 相似文献

Predictors of Condom Use in Mexican Migrant Laborers 总被引:5,自引:0,他引:5

The purpose of this study was to explore predictors of condom use with occasional sex partners and regular sex partners, as well as carrying condoms in a new high-risk group for HIV infection, Mexican migrant laborers. This study extends previous findings by (1) exploring additional predictors not previously examined, (2) utilizing a large sample of male and female Mexican migrant laborers, (3) carefully controlling for the effects of various demographic and lifestyle variables related to condom use, and (4) assessing the interactive effects of gender on predictors of condom use. Snowball sampling was used to survey 501 adult Mexican migrant laborers. Results revealed that condom use with occasional sex partners was predicted by carrying condoms and condom self-efficacy and that women were more likely to use condoms with occasional partners when both men and women knew someone with HIV/AIDS. Condom use with regular sex partners was predicted by procondom social norms, less negative attitudes toward condoms, not knowing someone with HIV/AIDS, and condom self-efficacy. Carrying condoms was predicted by procondom social norms, less negative attitudes toward condoms, condom self-efficacy, worry about contracting HIV/AIDS, and women were more likely than men to carry condoms when both men and women were married. Understanding these findings, future research directions, and implications for condom promotion strategies with Mexican migrant laborers are discussed. 相似文献

We studied performance on the Grooved Pegboard Test upon repeated trials and transfer of training between the hands in the first trial. The classification of handedness was based on the writing hand. We employed three trials for each hand and two different protocols for the order in which the hands started the test. For the three trials combined, women were faster than men. From the first to the second trial, there was an improvement in performance for both sexes. Within the first trial, sex differences reached significance and the protocol interacted with handedness. In this trial, only left-handed men were found to benefit from previous opposite-hand performance. It is speculated that a larger corpus callosum in left-handed men allows for the greater transfer of training between the hands. 相似文献

The aim of this study was to analyze the psychometric properties of the Spanish translation of the List of Social Situation Problems (LSSP; S. H. Spence, 1980). The questionnaire was administered to a sample of 388 adolescents between the ages of 12 and 18. Exploratory factor analysis identified four factors: Social Anxiety, Adult Oppositional, Assertiveness, and Making Friends, which accounted for 26.64% of the variance. Internal consistency of the total scale was high ( = .86). Correlations between the LSSP and two self-report measures of social anxiety, the Questionnaire about Interpersonal Difficulties for Adolescents (r = .45) and the Social Phobia and Anxiety Inventory (r = .48), were statistically significant. A significant difference was found between LSSP total scores for adolescents with and without social anxiety (d = 1.14), supporting the construct validity of the scale. 相似文献

In this paper, decision making under time pressure for multiattribute choice alternatives in a risky environment is investigated. A model, multiattribute decision field theory (MDFT), is introduced that describes both the dynamic and the stochastic nature of decision making and accounts for the observed changes in choice probabilities, including preference reversals as a function of time limit. An experiment in which five different time limits were imposed on the decision maker is presented to test the predictions of the model. It is shown that MDFT is able to account for the complex decision behavior observed in the data. Furthermore, MDFT is compared with the predictions of decision field theory (Busemeyer & Townsend, 1993; Roe, Busemeyer, & Townsend, 2001). 相似文献

Conflict and choice are closely related in that choice produces conflict and conflict is resolved by making a choice. Although
conflict was invoked in psychological approaches to decision making early on (Lewin, 1931/1964), no generally accepted measure
of conflict strength has been established (Tversky & Shafir, 1992). The present study introduces a model (multiattribute decision
field theory) that predicts a decision time pattern depending on the conflict situation. In a risky decision-making experiment
with multiattribute choice alternatives, decision time is investigated as a possible measure of conflict strength. It is shown
that the model can be fitted to a complex choice pattern. 相似文献

Community psychology and the psychology of liberation provide a framework to analyze colonization. Puerto Rico has always been a colony. This experience has direct negative effects on Puerto Ricans' national identities and their emotions. The purpose of this study was to explore emotions associated with Puerto Rican national identities in a sample of 35 high school students. While participating in 4 focus groups, the youths discussed negative and positive emotions associated to their national identities. The most frequent ones were shame and pride. They also identified situations which promoted negative and positive emotions. The role of a community psychology of liberation in understanding these phenomena as well as in embracing resistance to colonization is discussed. 相似文献
