A series of 14 field experiments on the differential treatment of ethnic majority and minority groups were conducted. In all studies, German participants were confronted with a German or a foreign confederate (ostensibly a member of the migrant-worker population or a refugee/asylum seeker). In 9 experiments, the foreign confederate received worse treatment than did his German counterpart. Meta-analyses showed a significant overall correlation between ethnic group membership and indexes of discrimination (r= .24), which support the assumption of everyday ethnic discrimination in Germany. Categorizing studies according to the directness of interaction between confederate and participants revealed a significantly stronger discrimination in remote contact situations (r= .34 vs. r= .17), replicating results of a review on American studies by Crosby, Bromley, and Saxe (1980). 相似文献

A statistical analysis revealed the following concerning auditory agnosia. (1) Bilateral temporal lobe lesions prevailed; in a minority of cases unilateral lesions were verified. (2) The syndrome occurred as a result of repeated insults. (3) There was a statistically significant correlation between the side of the first insult and the predilective type of the syndrome, i.e., agnosia preferably for linguistic with respect to nonlinguistic material. On the basis of these results we discuss the principle of contralateral compensation and the hypothesis of lesional interference. In doing so a conceptual model of interhemispheric functional relationships is developed. We made use of a set theory-oriented interpretation of Kinsbourne's “attention-model” (M. Kinsbourne, 1970, Acta Psychologica 33, 193–201). 相似文献

In reaction time (RT) tasks, responses are especially fast when participants can anticipate the onset of an imperative response
signal. Although this RT facilitation is commonly attributed to temporal preparation, it is unclear whether this preparation
shortens the duration of early or late processes. We used the effect propagation property of the psychological refractory
period paradigm to localize the effect of temporal preparation. Manipulation of temporal uncertainty affected the RT of Task
1, regardless of the level of stimulus onset asynchrony (SOA). Consistent with the prediction of an early locus of temporal
preparation, this effect propagated completely to the RT of Task 2 at short SOAs, but propagation diminished virtually to
zero at long SOAs. 相似文献

In this study, we investigated biomechanical contributions of the high guard position of the arms observed only in a subgroup of toddlers at very early stages of gait development. Six healthy toddlers who showed this peculiar arm posture were involved in this study. They participated in two data collection sessions (1 month apart). We used three-dimensional analysis of arm posture during gait to estimate the changes in forces and torques generated by the arms and acting on the upper trunk segment. Across visits, toddlers’ increase in walking speeds coincided with lowering arm postures. Despite the apparent trend of changes in arm posture in this group of toddlers, the interaction between arm posture and upper trunk position created a variety of changes in forces and torques among individuals. Findings of this study exhibited an example of the exploration of dynamics by toddlers in the early stage of gait development. 相似文献

Feelings of shame and guilt are factors associated with depression. However, studies simultaneously investigating shame and guilt suggest that only shame has a strong unique effect, although it is not yet clear which psychological processes cause shame and not shame-free guilt to be related to depression. The authors hypothesized that shame, in contrast to guilt, elicits rumination, which then leads to depression. Therefore, in this study we investigated event-related shame and guilt, event-related rumination, and depression among 149 mothers and fathers following family breakup due to marital separation. Data were analyzed using latent variable modeling. The results confirm that shame but not guilt has a strong unique effect on depression. Moreover, the results show that the effect of shame is substantially mediated by rumination. The results are discussed against the background of self-discrepancies and self-esteem. 相似文献

A comparison was made between reading tasks performed with and without the additional requirement of detecting target letters. At issue was whether eye movement measures are affected by the additional requirement of detection. Global comparisons showed robust effects of task type with longer fixations and fewer word skippings when letter detection was required. Detailed analyses of target words, however, further showed that reading with and without letter detection yielded virtually identical effects of word class and text predictability for word-skipping rate and similar effects for different word viewing duration measures. The overall oculomotor pattern suggested that detection does not substantially shift normal reading movements in response to lexical cues and thereby indicated that detection tasks are informative about word and specifically word class processing in normal reading. 相似文献
