选择性注意的分心物加工机制对工作记忆的影响 总被引:5,自引:0,他引:5
通过实验法严格筛选被试,探讨了在有无分心物干扰的条件下,选择性注意的分心物加工机制(分心物抑制机制、分心物习惯化机制)对工作记忆的影响。结果揭示了,分心物抑制机制不仅能影响工作记忆的储存而且还影响工作记忆的加工;而习惯化机制只影响工作记忆的储存,不影响工作记忆的加工。 相似文献

Integrating distinctiveness theory and contact theory, we develop a conceptual model proposing that prior intercultural contact has mediated effects on international leadership potential via cultural intelligence—but that these effects are stronger for majorities. Results of two samples of working adults, using both self‐report (n= 441, Study 1) and matched employee‐observer (n= 181, Study 2) data provide strong support for the model. Cultural intelligence mediates the effects of prior intercultural contact on international leadership potential. Further, moderated mediation analyses demonstrate that cultural intelligence mediates the relationship between prior intercultural contact and international leadership potential for majorities, but not for minorities. The current study offers contributions to theory and practice in at least two ways. First, the proposed model is theoretically important because it provides a more complete picture of predictors of international leadership potential and it reconciles prior inconsistent findings by showing the mediating role of cultural intelligence and moderating role of minority status. Second, the study adds to the increasing evidence suggesting that prior intercultural contact and cultural intelligence are meaningful criteria for developing international leaders. More important, results show that prior intercultural contact is especially important for majorities. 相似文献

Male zebra finches (Taeniopygia guttata) learn to sing during a critical period in adolescence. We previously described a presynaptic protein, synelfin, whose mRNA is increased early in this critical period in a brain nucleus specifically implicated in song learning, lateral MAN (lMAN). In the current study, in situ hybridization was used to map this change in gene expression to the subregion of lMAN that projects to the robust nucleus of the archistriatum (RA), the principal motor output of the telencephalic circuit that controls song production. Using confocal immunofluorescence microscopy, we detected numerous puncta of synelfin immunoreactivity that apparently represent presynaptic terminals from lMAN in the RA of young males. Synelfin immunoreactivity in RA declined abruptly between 40 and 45 days of age, a time of major synaptic reorganization in RA. This change did not occur until about 10 days after the decline in synelfin mRNA in cell bodies within lMAN, indicating a relatively slow turnover of the protein in presynaptic terminals and suggesting that some of the functional changes that occur during the critical period may arise from regulatory decisions that were initiated a week or more earlier. Depriving birds of tutoring did not halt or delay the decline of synelfin mRNA in lMAN. This change in gene expression must not be a consequence of early song learning, but may reflect an innate or programmed step in song circuit development. 相似文献

We introduce and explore a color phenomenon which requires the prior perception of motion to produce a spread of color over a region defined by motion. We call this motion-induced spread of colordynamic color spreading. The perception of dynamic color spreading is yoked to the perception of apparent motion: As the ratings of perceived motion increase, the ratings of color spreading increase. The effect is most pronounced if the region defined by motion is near 1° of visual angle. As the luminance 相似文献
