The present study examined the effect of level of traditional masculine gender role norms as well as the moderating effect of cognitive flexibility on community reintegration outcomes in a sample of 60 male military veterans who had sustained a traumatic brain injury during deployment. Data were collected through self-report measures and cognitive tests. Results suggested that greater endorsement of traditional masculine gender role beliefs, attitudes, and behaviors was significantly inversely related to the community integration domains of relationships and living skills and not significantly related to work and leisure. The effect of masculinity on healthy living skills was moderated by cognitive flexibility; the protective effect of low masculinity on living skills was only present if the veteran also had high cognitive flexibility skills. Results are discussed in the context of gender role strain, potential limiting aspects of stereotypy on recovery and reintegration, and the importance of cognitive flexibility in the recovery/reintegration process. 相似文献

AbstractThe concepts and methods used by regulatory agencies worldwide to assess the safety of flavouring additives were designed by and for the flavouring industry. They embody and embed, in routine regulatory practice, the industry's commercial interests in minimising regulatory costs and the risk that the market for its products might be restricted. First sketched out by US flavouring company scientists in the early 1960s, this approach required almost no experimental data, and was highly permissive, relative to both our knowledge (and lack of it) about chemical toxicity and the ways other kinds of food additives are regulated. A ‘realist constructivist’ analysis illustrates how the industry's approach was also anti-scientific and unscientific because it served to discourage scientific investigation of important aspects of the phenomena it purported to evaluate, and because it relied on assumptions and hypotheses that lacked any evidential basis. The industry approach was first used to assess flavourings in the USA, where the industry was allowed to design and run its own regulatory regime. In all other regulatory jurisdictions, the industry's approach was rejected; expert advisors argued that it was incompatible with mandates to protect consumer health. Yet, the approach eventually prevailed everywhere. It did so in large part because of the collective refusal of the flavouring industry over three decades to provide the experimental data that had been requested by the regulatory authorities. This has been a form of regulatory capture, which was triggered by a remarkably effective tactic of non-cooperation with demands for data. 相似文献

ABSTRACTThe image on our retina changes every time we make an eye movement. To maintain visual stability after saccades, specifically to locate visual targets, we may use nontarget objects as “landmarks”. In the current study, we compared how the presence of nontargets affects target localization after saccades and during sustained fixation. Participants fixated a target object, which either maintained its location on the screen (sustained-fixation trials), or displaced to trigger a saccade (saccade trials). After the target disappeared, participants reported the most recent target location with a mouse click. We found that the presence of nontargets decreased response error magnitude and variability. However, this nontarget facilitation effect was not larger for saccade trials than sustained-fixation trials, indicating that nontarget facilitation might be a general effect for target localization, rather than of particular importance to post-saccadic stability. Additionally, participants’ responses were biased towards the nontarget locations, particularly when the nontarget-target relationships were preserved in relative coordinates across the saccade. This nontarget bias interacted with biases from other spatial references, e.g., eye movement paths, possibly in a way that emphasized non-redundant information. In summary, the presence of nontargets is one of several sources of reference that combine to influence (both facilitate and bias) target localization. 相似文献

ABSTRACTWe live in a 3D world, and yet the majority of vision research is restricted to 2D phenomena, with depth research typically treated as a separate field. Here we ask whether 2D spatial information and depth information interact to form neural representations of 3D space, and if so, what are the perceptual implications? Using fMRI and behavioural methods, we reveal that human visual cortex gradually transitions from 2D to 3D spatial representations, with depth information emerging later along the visual hierarchy, and demonstrate that 2D location holds a fundamentally special place in early visual processing. 相似文献

ABSTRACTDifferences in eye movement patterns are often found when comparing passive viewing paradigms to actively engaging in everyday tasks. Arguably, investigations into visuomotor control should therefore be most useful when conducted in settings that incorporate the intrinsic link between vision and action. We present a study that compares oculomotor behaviour and hazard reaction times across a simulated driving task and a comparable, but passive, video-based hazard perception task. We found that participants scanned the road less during the active driving task and fixated closer to the front of the vehicle. Participants were also slower to detect the hazards in the driving task. Our results suggest that the interactivity of simulated driving places increased demand upon the visual and attention systems than simply viewing driving movies. We offer insights into why these differences occur and explore the possible implications of such findings within the wider context of driver training and assessment. 相似文献

This paper was the Mary Hemingway Rees Memorial Lecture, delivered at the XXIst World Assembly for Mental Health, Vancouver, Canada, 2001. The author had recently completed a period of appointment as the New Zealand Commissioner for Mental Health. In this lecture, the author puts in a moving plea - as a survivior of mental illness - for considering both spirituality and mental health in terms of the experience of the self. She talks about the value of communication particularly by sharing experiences via personal stories. The author goes on to contrast communication and control, and to emphasize the importance of making space in order to accept our own and others' imperfections and vulnerabilities. Attention is drawn to the work of Baruk (1978, 1998, 1999, 2000). She also discusses the way in which mental illness can lead to spiritual progress, and ultimately to mental health. The original version of the talk contained further pictorial illustrations; for technical reasons it would be difficult to reproduce all of them here in the journal. Most of the illustrative material consisted of photographs by the author, including the two photographs that are reproduced in this paper. 相似文献

ABSTRACT A challenge in habitual prospective memory tasks (e.g., taking medication) is remembering whether or not one has already performed the action. Einstein, McDaniel, Smith, and Shaw (1998, Psychological Science, 9, 284) showed that older adults were more likely to incorrectly repeat an action on habitual prospective memory tasks. Extending this research, we (a) biased participants either toward repetition or omission errors, (b) investigated whether performing a more complicated motor action can reduce repetition errors for older adults, and (c) examined participants' resource allocation to the prospective memory task. Older adults committed more repetition errors than younger adults regardless of biasing instructions when ongoing task demands were challenging (Experiment 1). Performing the more complex motor action, however, reduced repetition errors for older adults. Further, when the ongoing task was less demanding, older adults' repetition errors declined to levels of younger adults (Experiment 2). Consistent with this finding, the resource allocation profiles suggested that older participants were monitoring their output (prospective memory execution) in each trial block. 相似文献
