Agentic female leaders risk social and economic penalties for behaving counter-stereotypically (i.e., backlash; Rudman, 1998), but what motivates prejudice against female leaders? The status incongruity hypothesis (SIH) proposes that agentic women are penalized for status violations because doing so defends the gender hierarchy. Consistent with this view, Study 1 found that women are proscribed from dominant, high status displays (which are reserved for leaders and men); Studies 2–3 revealed that prejudice against agentic female leaders was mediated by a dominance penalty; and in Study 3, participants' gender system-justifying beliefs moderated backlash effects. Study 4 found that backlash was exacerbated when perceivers were primed with a system threat. Study 5 showed that only female leaders who threatened the status quo suffered sabotage. In concert, support for the SIH suggests that backlash functions to preserve male dominance by reinforcing a double standard for power and control.  相似文献

Previous studies on autism have shown a lack of motor anticipation in children and adults with autism. As part of a programme of research into early detection of autism, we focussed on an everyday situation: spoon-feeding. We hypothesize that an anticipation deficit may be found very early on by observing whether the baby opens his or her mouth in anticipation of the spoon's approach. The study is based on a retrospective analysis from family home movies. Observation of infants later diagnosed with autism or an autism spectrum disorder (ASD) (n = 13) and infants with typical development (n = 14) between 4 and 6 months old show that the autism/ASD group has an early anticipation deficit.  相似文献

This research investigates children's use of social categories in their food selection. Across three studies, we presented preschoolers with sets of photographs that contrasted food-eating models with different characteristics, including model gender, race (Black, White), age (child or adult), and/or expression (acceptance or rejection of the food). Children were asked to pick between the photographs to choose which food they would like for snack. Results demonstrated that preschoolers prefer foods being eaten by models with positive over negative expressions, foods being eaten by child over adult models, and foods being eaten by child models of the same gender as themselves over models of the other gender. This work connects with previous research on children's understanding of social categories and also has important practical implications for how characteristics of a food-eating model can affect children's willingness to try new foods.  相似文献

Background: Few published studies have addressed the male experience of alcohol dependency. Aim: This paper seeks to address this deficiency and to highlight aspects of the male experience relevant to the counselling and psychotherapy profession. Methods: Six men in recovery from alcohol dependency participated in semi‐structured interviews. Findings: A grounded theory analysis elicited five core categories, Beginning to Drink, Paying for Gain with Pain, Reaching Rock Bottom, Struggling to Recover and Leading a New Life. Despite the pain they had experienced, participants' narratives were matter‐of‐fact and goal‐oriented. Low self‐esteem was expressed indirectly. Conclusions: These findings are consistent with socialisation models of alcoholism. Counsellors, and the wider profession, must be alert for the male under‐reporting of emotional distress.  相似文献

The relations between young children's mutual (reciprocated) and overall positive emotion (PE) with same- and other-gender peers and their social adjustment were explored. Children's PE and peers' PE were observed across the preschool year during peer interactions (N = 166; 46% girls; M age = 52 months). Results revealed that girls and boys had similar frequencies of overall PE and mutual PE when interacting with same-gender peers, but girls were marginally higher compared with boys in overall and mutual PE when interacting with other-gender peers. Girls and boys did not have greater rates of either type of PE after controlling for gender segregation during same- or other-gender interactions. Using structural equation modeling, children's mutual PE, regardless of their gender, positively predicted indicators of positive adjustment (e.g., prosocial behavior, cooperation) and negatively predicted indicators of negative adjustment (e.g., hyperactivity, disruption, exclusion by peers). Children's overall PE did not predict either type of adjustment. Findings support the importance of mutual PE for children's development.  相似文献

Negative feedback can signal poor performance, but it also provides information that can help learners reach the goal of task mastery. The primary aim of this study was to test the hypothesis that the amount of information provided by negative feedback during a paired-associate learning task influences feedback-related processing in the caudate nucleus. To do this, we manipulated the number of response options: With two options, positive and negative feedback provide equal amounts of information, whereas with four options, positive feedback provides more information than does negative feedback. We found that positive and negative feedback activated the caudate similarly when there were two response options. With four options, the caudate’s response to negative feedback was reduced. A secondary goal was to investigate the link between brain-based measures of feedback-related processing and behavioral indices of learning. Analysis of the posttest measures showed that trials with positive feedback were associated with higher posttest confidence ratings. Additionally, when positive feedback was delivered, caudate activity was greater for trials with high than with low posttest confidence. This experiment demonstrated the context sensitivity of feedback processing and provided evidence that feedback processing in the striatum can contribute to the strengthening of the representations available within declarative memory.  相似文献

A major difference between humans and other animals is our capacity to maintain information in working memory (WM) while performing secondary tasks, which enables sustained, complex cognition. A common assumption is that the lateral prefrontal cortex (PFC) is critical for WM performance in the presence of distracters, but direct evidence is scarce. We assessed the relationship between fMRI activity and WM performance within subjects, with performance matched across distracter and no-distracter conditions. Activity in the ventrolateral PFC during WM encoding and maintenance positively predicted performance in both conditions, whereas activity in the presupplementary motor area (pre-SMA) predicted performance only under distraction. Other parts of the dorsolateral and ventrolateral PFCs predicted performance only in the no-distracter condition. These findings challenge a lateral-PFC-centered view of distracter resistance, and suggest that the lateral PFC supports a type of WM representation that is efficient for dealing with task-irrelevant input but is, nonetheless, easily disrupted by dual-task demands.  相似文献

Growing evidence suggests that visual information is processed differently in the near-hand space, relative to the space far from the hands. To account for the existing literature, we recently proposed that the costs and benefits of hand proximity may be due to differential contributions of the action-oriented magnocellular (M) and the perception-oriented parvocellular (P) pathways. Evidence suggests that, relative to the space far from the hands, in near-hand space the contribution of the M pathway increases while the contribution of the P pathway decreases. The present study tested an important consequence of this account for visual representation. Given the P pathway’s role in feeding regions in which visual representations of unified objects (with bound features) are formed, we predicted that hand proximity would reduce feature binding. Consistent with this prediction, two experiments revealed signs of reduced feature binding in the near-hand space, relative to the far-hand space. We propose that the higher contribution of the M pathway, along with the reduced contribution of the P pathway, shifts visual perception away from an object-based perceptual mode toward a feature-based mode. These results are discussed in light of the distinction between action-oriented and perception-oriented vision.  相似文献

This study examines the links between employee perceptions of job insecurity, the work–nonwork interface, and stress‐related outcomes. Drawing on an adaptation perspective, we expect employees feeling greater job insecurity to engage in adaptive work behaviors including less use of work–nonwork support programs and greater willingness to let work permeate into one's personal life, which in turn will associate with greater work–nonwork conflict and emotional exhaustion. Data were collected from employees within a large energy company at 2 points in time. Results support the model, offering important insights into employee behavioral responses to job insecurity and key mechanisms through which insecurity may foster diminished employee well‐being.  相似文献

Sensitivity to the extra-linguistic context, as exhibited by indexical and demonstrative expressions, and sensitivity to the linguistic context, as exhibited by, for example, anaphoric uses of third person pronouns, are regularly regarded as different and independent phenomena. The data on indexicals, demonstratives, and third person pronouns, however, call for a more unified notion of context and of context sensitivity. This paper aims to develop such a unified picture by generalizing the notion of anaphora to encompass extra-linguistic context dependency and generalizing the notion of a structured discourse context so that contexts contain antecedents for expressions that refer to entities in the extra-linguistic context.  相似文献
