When does dual identity predict protest? The moderating roles of anti‐immigrant policies and opinion‐based group identity 下载免费PDF全文
Shaun Wiley Jessica Figueroa Taylor Lauricella 《European journal of social psychology》2014,44(3):209-215
Dual identities are defined as immigrants' identification with their ethnic ingroup as well as the national community in their country of residence. Dual identities have been argued to increase protest, because they make immigrants feel entitled to advocate for their disadvantaged ethnic group as part of a larger national community. In a study of Latino immigrants to the United States, however, we found that dual identities no longer predict protest when immigrants learn that other members of the national community have passed laws or enacted policies that would exclude immigrants or restrict their rights, through deportation and detention. Further, we found that immigrants who identify with those fighting to change such anti‐immigrant policies support protest regardless of the level of their dual identity and regardless of policy salience. We argue that these results point to the importance of dual identity recognition for research on immigrant protest. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

This study provides the first meta‐analytic testing of (1) several proposed moderators of the relationship between employee weight and job‐related outcomes (e.g., target gender, target qualifications, and rater gender); and (2) the effect of specific design features on the variation in results obtained across relevant experimental studies (e.g., weight manipulation and amount of job‐relevant information). The results indicate that there are important moderators of the relationship between people's weight and job‐related outcomes. However, design feature may significantly influence the obtained results. In particular, inconsistent experimental findings regarding the hypothesized moderating role of target sex appear to be explained by limitations in the way in which target weight was manipulated in some studies. Directions for future research are identified. 相似文献

Hand position in the visual field influences performance in several visual tasks. Recent theoretical accounts have proposed that hand position either (a) influences the allocation of spatial attention, or (b) biases processing toward the magnocellular visual pathway. Comparing these accounts is difficult as some studies manipulate the distance of one hand in the visual field while others vary the distance of both hands, and it is unclear whether single and dual hand manipulations have the same impact on perception. We ask if hand position affects the spatial distribution of attention, with a broader distribution of attention when both hands are near a visual display and a narrower distribution when one hand is near a display. We examined the effects of four hand positions near the screen (left hand, right hand, both hands, no hands) on both temporal and spatial discrimination tasks. Placing two hands near the display compared to two hands distant resulted in improved sensitivity for the temporal task and reduced sensitivity in the spatial task, replicating previous results. However, the single hand manipulations showed the opposite pattern of results. Together these results suggest that visual attention is focused on the graspable space for a single hand, and expanded when two hands frame an area of the visual field. 相似文献

Abstract Faces, as a class of objects, have been studied extensively in order to understand how the human visual system recognizes and represents objects. In this paper we studied the ontogeny of the ability to perceive gaze direction. We bring together both developmental research and neurophysiological and neuropsychological research in order to address this issue. In two experiments we explored the developmental time course of the ability to discriminate between direct and averted gaze, a task thought to involve cortical information processing of faces. We found that (a) infants as young as four months could discriminate between direct and averted gaze, (b) this ability was not due to the development of low-level visual processes, and (c) younger infants did not show reliable evidence of gaze discrimination. In an additional experiment we tested adults to study the effect of face context on the ability to discriminate gaze direction. Adult subjects were more sensitive in this discrimination when the eyes were in the context of an upright face than when the eyes were in either an inverted face or in a scrambled face. Taken together, these results suggest that the mechanisms underlying gaze detection may be mediated by cortical circuits also involved in other aspects of face recognition. 相似文献

Prenatal and perinatal risk factors, such as low birth weight, have been linked to higher levels of aggressive and destructive behaviours during childhood. Although low birth weight is associated with childhood externalizing behaviour, the mechanisms underlying this relationship remain open to empirical investigation. The current study extends the current literature by examining whether verbal skills mediate the relationship between low birth weight and childhood externalizing behaviour. A longitudinal analysis of data from the Fragile Families and Child Well‐being Study reveals that verbal skills appear to mediate the influence of low birth weight on serious aggression and destructive behaviour at age 5. The implications of this research are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Poststroke depression (PSD) is the most frequent psychological sequela following stroke. While previous studies describe the impact of age on brain infarct volume, brain edema, and blood–brain barrier (BBB) breakdown following ischemia, the role of age on PSD has yet to be described. Here, we examine the influence of age on PSD progression in a rat model of PSD by middle cerebral artery occlusion (MCAO). One hundred forty-three rats were divided into three groups. 48 rats 20 weeks of age underwent a sham procedure, 51 rats 20 weeks of age had MCAO, and 44 rats 22–26 months of age had MCAO. Groups were further divided into two subgroups. The first subgroup was used to measure infarct lesion volume, brain edema, and BBB breakdown at 24 h. In the second subgroup at 3 weeks after MCAO, rats were subjected to a sucrose preference test, two-way shuttle avoidance task, forced swimming test, and a brain-derived neurotrophic factor (BDNF) protein level measurement. Total and striatal infarct volume, brain edema, and BBB breakdown in the striatum were increased in older rats, as compared with younger rats. While both old and young rats exhibited depressive-like behaviors on each of the behavioral tests and lower BDNF levels post-MCAO, as compared with control rats, there were no differences between old and young rats. Although older rats suffered from larger infarct volumes, increased brain edema and more BBB disruption following MCAO, the lack of behavioral differences between young and old rats suggests that there was no effect of rat age on the incidence of PSD. 相似文献
