In two-choice tasks, the compatible mapping of left stimulus to left response and right stimulus to right response typically yields better performance than does the incompatible mapping. Nonetheless, when compatible and incompatible mappings are mixed within a block of trials, the spatial compatibility effect is eliminated. Two experiments evaluated whether the elimination of compatibility effects by mixing compatible and incompatible mappings is a general or specific phenomenon. Left-right physical locations, arrow directions, and location words were mapped to keypress responses in Experiment 1 and vocal responses in Experiment 2. With keypresses, mixing compatible and incompatible mappings eliminated the compatibility effect for physical locations and arrow directions, but enhanced it for words. With vocal responses, mixing significantly reduced the compatibility effect only for words. Overall, the mixing effects suggest that elimination or reduction of compatibility effects occurs primarily when the stimulus-response sets have both conceptual and perceptual similarity. This elimination may be due to suppression of a direct response-selection route, but to account for the full pattern of mixing effects it is also necessary to consider changes in an indirect response-selection route and the temporal activation properties of different stimulus-response sets. 相似文献

Adolescence is a high-risk period for body image disturbance and appearance concerns. In a cascade model, we examined interrelations of body dysmorphic symptoms (BDS) with appearance rejection sensitivity (ARS) and tested gender moderation. Participants were 397 Australian adolescents (T1 Mage = 11.7, SD = 0.91; 56% girls) who completed six surveys over 4 years. In a random-intercept cross-lag model, two (of five possible) paths showed ARS predicted higher subsequent BDS, and three (of five possible) paths showed BDS predicted higher subsequent ARS. Girls reported more BDS and ARS than boys, and random intercepts of BDS and ARS were correlated with the correlation stronger in girls than boys. Cross-lag BDD-ARS associations over the six waves were not significantly moderated by gender. Overall, girls are at higher risk of appearance concerns than boys, but BDD-ARS cascade effects do not differ between girls and boys. 相似文献

La littérature portant sur la culture des organisations souffre d'un manque manifeste d'enquêtes extensives débouchant sur des études comparatives. Afin de rendre plus comparables les cultures organisationnelles, nous proposons une définition et une série de dimensions. La culture organisationnelle renverrait aux perceptions communes des pratiques de travail dans le cadre des unités constitutives des organisations. A l'examen d'études empiriques, les cinq dimensions suivantes nous sont apparues: autonomie, orientation externe, coordination interdépartementale, orientation vers les ressources humaines et orientation vers le développement. L'utilisation de cette définition et de ces dimensions générales devrait faciliter la comparaison des cultures organisationnelles et l'accumulation de résultats.
Within the body of organisation culture literature, there is a conspicuous absence of large-scale studies reporting on comparative studies. In order to increase comparability of organisational cultures we propose a definition and a set of dimensions. Organisational culture is defined as shared perceptions of organisational work practices within organisational units. On the basis of empirical studies we discerned the following five dimensions: autonomy, external orientation, interdepartmental coordination, human resource orientation, and improvement orientation. Use of this definition and a set of such generic dimensions would facilitate the comparison of organisational cultures and the accumulation of research findings. 相似文献

Several previous studies have shown that memory span is greater for short words than for long words. This effect is claimed to occur even when the short and long words are matched for the number of syllables and phonemes and so to provide evidence for subvocal articulation as being one mechanism that underlies memory span (Baddeley, Thomson, & Buchanan, 1975). The three experiments reported in this paper further investigate the articulatory determinants of word length effects on span tasks. Experiment 1 replicated Baddeley et al.'s finding of an effect of word length on auditory and visual span when the stimuli consist of words that differ in terms of the number of syllables. Experiments 2 and 3 showed that the effects of word length are eliminated when the words in the span task are matched for the number of syllables and phonemes but differ with respect to the duration and/or complexity of their articulatory gestures. These results indicate that it is the phonological structure of a word and not features of its actual articulation that determines the magnitude of the word length effect in span tasks. 相似文献
