The main aim of this study was to provide a detailed examination of the nature of the messages that adolescent boys and girls receive about their bodies. Forty adolescent boys and 40 adolescent girls participated in an in-depth interview to gain an understanding of the range of potential ‘sources’ of body-related messages. Messages were organized around the source of these messages (self, mother, father, brother, sister, female friends, male friends, media). There were consistent gender differences in the way that adolescents received and interpreted messages about their bodies. Overall girls received more positive and more negative messages than boys did. Boys reported having received virtually no negative messages from most people. The content of internal dialogue among adolescents revealed that messages about the body could be interpreted, distorted, and deflected. The implications of these findings for preventing body image-related problems and disordered eating among adolescents are discussed. 相似文献

A brief glimpse of a scene can guide eye movements but it remains unclear how prior target knowledge influences early scene processing. Using the ‘flash-preview moving window’ (FPMW) paradigm to restrict peripheral vision during search, we manipulated whether target identity was presented before or after previews. Windowed search was more efficient following 250?ms scene previews, and knowing target identity beforehand further improved how search was initiated and executed. However, in Experiment 2 when targets were removed from scene previews, only the initiation of search continued to be modulated by prior activation of target knowledge. Experiment 3 showed that search benefits from scene previews are maintained even when repeatedly searching through the same type of scene for the same type of target. Experiment 4 replicated Experiment 3 whilst also controlling for differences in integration times. We discuss the flexibility of the FPMW paradigm to measure how the first glimpse affects search. 相似文献

In times of social and moral crises, sport has often been called to boost individual moral development. By the same token, outdoor activities are viewed as good educational practices to enhance environmental responsibility. However, the present paper argues that these physical activities are currently following the same technological development trend as the mainstream society, and challenges this trend itself in terms of sustainability by critically asking this question: Do outdoor activities really enhance environmental responsibility? The research supporting this paper is based on a qualitative inquiry using interviews with outdoor activities practitioners: mountain guides and white water sports instructors. The findings of this research show that environmental responsibility development depends on the sport contexts. It is fostered in slow and none-technological activities (e.g. trekking) and lowered in fast and technological activities (e.g. canoeing, kayaking). The paper concludes with the following paradox reached by the preliminary research results: the birth of modern technology calls for greater need of environmental responsibility, but it may also prevent its development at the same time. 相似文献

Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are commonly comorbid, share genetic liability, and often exhibit overlapping cognitive impairments. Clarification of shared and distinct cognitive effects while considering comorbid symptoms across disorders has been lacking. In the current study, children ages 7–15 years assigned to three diagnostic groups:ADHD (n?=?509), ASD (n?=?97), and controls (n?=?301) completed measures spanning the cognitive domains of attention/arousal, working memory, set-shifting, inhibition, and response variability. Specific processes contributing to response variability were examined using a drift diffusion model, which separately quantified drift rate (i.e., efficiency of information processing), boundary separation (i.e., speed-accuracy trade-offs), and non-decision time. Children with ADHD and ASD were impaired on attention/arousal, processing speed, working memory, and response inhibition, but did not differ from controls on measures of delayed reward discounting, set-shifting, or interference control. Overall, impairments in the ASD group were not attributable to ADHD symptoms using either continuous symptom measures or latent categorical grouping approaches. Similarly, impairments in the ADHD group were not attributable to ASD symptoms. When specific RT parameters were considered, children with ADHD and ASD shared impairments in drift rate. However, children with ASD were uniquely characterized by a wider boundary separation. Findings suggest a combination of overlapping and unique patterns of cognitive impairment for children with ASD as compared to those with ADHD, particularly when the processes underlying reaction time measures are considered separately. 相似文献

The influence of emotion on episodic and autobiographical memory in schizophrenia was investigated. Using an experiential approach, the states of awareness accompanying recollection of pictures from the IAPS and of associated autobiographical memories was recorded. Results show that schizophrenia impairs episodic and autobiographical memories in their critical feature: autonoetic awareness, i.e., the type of awareness experienced when mentally reliving events from one's past. Schizophrenia was also associated with a reduction of specific autobiographical memories. The impact of stimulus valence on memory performance was moderated by clinical status. Patients with schizophrenia recognized more positive than negative pictures, and recalled more positive than negative autobiographical memories while controls displayed the opposite pattern. A hypothesis in terms of a fundamental executive deficit underlying these impairments is proposed. 相似文献

We draw on 146 employee‐co‐worker‐supervisor triads from 146 organizations to examine the role of individual perspective‐taking and team creative environment in the association between individual creativity and organizational innovation. Adopting an interactionist perspective, we find that the link between individual creativity and organizational innovation is most clearly strengthened when individual perspective‐taking and team creative environment are both high. Neither individual perspective‐taking nor team creative environment alone moderated the relationship between creativity and innovation. 相似文献

Nowadays, sports betting has become increasingly available and easy to engage in. Here we examined the neural responses to stimuli that represent sporting events available for betting as compared to sporting events without a gambling opportunity. We used a cue exposure task in which football (soccer) fans (N = 42) viewed cues depicting scheduled football games that would occur shortly after the scanning session. In the “betting” condition, participants were instructed to choose, at the end of each block, the game (and the team) they wanted to bet on. In the “watching” condition, participants chose the game they would prefer to watch. After the scanning session, participants completed posttask rating questionnaires assessing, for each cue, their level of confidence about the team they believed would win and how much they would enjoy watching the game. We found that stimuli representing sport events available for betting elicited higher fronto-striatal activation, as well as higher insular cortex activity and functional connectivity, than sport events without a gambling opportunity. Moreover, games rated with more confidence towards the winning team resulted in greater brain activations within regions involved in affective decision-making (ventromedial prefrontal cortex), cognitive inhibitory control (medial and superior frontal gyri) and reward processing (ventral and dorsal striatum). Altogether, these novel findings offer a sensible simulation of how the high availability of sports betting in today’s environment impacts on the reward and cognitive control systems. Future studies are needed to extend the present findings to a sample of football fans that includes a samilar proportion of female and male participants. 相似文献
