变化视盲(change blindness)现象,也称变化盲,是指视觉情景中人们不能觉察到某个事物变化的现象。研究以驾驶员为主体探讨了道路交通领域中的变化视盲现象。首先,从场景变化特征和驾驶员特征两个方面综述了影响驾驶员变化视盲的影响因素;其次,结合影响因素与变化视盲的特征理论建立了驾驶员变化检测的认知过程模型;最后,在模型的基础上,讨论了提高驾驶员变化检测能力的实际意义和潜在措施,并对未来有关交通安全变化视盲的研究予以展望。  相似文献

Gay men and lesbians in South Korea are alienated and stigmatized due to the country's low tolerance of social differences, resulting in distress and suicidal impulses. This study investigated the predictors of suicidal ideation in a gay and lesbian group in South Korea based on the interpersonal‐psychological theory of suicide. Differences between the gay and lesbian group and the heterosexual group were found in the direct path between perceived burdensomeness and suicidal ideation. The relationship was significant for both groups, but the path coefficient was greater for lesbians and gay men than for heterosexuals. These findings imply that perceived burdensomeness may be a more critical factor in suicidal ideation of lesbians and gay men.  相似文献

The objective of this study was to identify factors associated with complete mental health among Canadians who had ever seriously considered suicide. Data for this study were obtained from Statistics Canada's 2012 Canadian Community Health Survey–Mental Health (N = 2,844). The outcome variable examined in this study was complete mental health and was analyzed using binary logistic regression. Of the 2,844 respondents with lifetime suicidal ideation, 1,088 (38.2%) had complete mental health (i.e., had flourishing mental health, no mental illness, and no suicidal ideation in the past 12 months). Those who had a confidant were seven times more likely to have complete mental health. Other factors associated with achieving complete mental health among formerly suicidal respondents include being older, being a woman, having higher income, use of religious coping, and never previously having a mental illness. Considering the importance of these protective factors in formulating public health policies will allow for a more wide‐reaching approach to suicide prevention.  相似文献

We investigated young children's awareness of the context‐relative rule structure of simple games. Two contexts were established in the form of spatial locations. Familiar objects were used in their conventional way at location 1, but acquired specific functions in a rule game at location 2. A third party then performed the conventional act at either of the two locations, constituting a mistake at location 2 (experimental condition), but appropriate at location 1 (control condition). Three‐year‐olds (but not 2‐year‐olds) systematically distinguished the two conditions, spontaneously intervening with normative protest against the third party act in the experimental, but not in the control condition. Young children thus understand context‐specific rules even when the context marking is non‐linguistic. These results are discussed in the broader context of the development of social cognition and cultural learning.  相似文献

Researchers tested the hypothesis that the negative impact of recent life events would moderate the relationship between intrinsic religiosity and death ideation in older adults. Participants (n = 272) completed assessments of death ideation, intrinsic religiosity, and negative impact of recent life events. We confirmed the presence of concurrent moderation and found that older adults with greater negative impact of recent life events and high intrinsic religiosity reported greater death ideation. These relatively surprising findings may be due to reduced fear of death in intrinsically religious older adults, an explanation consistent with previous research.  相似文献

We surveyed 868 Army chaplains and 410 chaplain assistants (CAs) about their role in identifying, caring for, and referring soldiers at risk of suicide to behavioral health care. We applied structural equation modeling to identify how behaviors and attitudes related to intervention behavior. In both samples, reluctance and stigma were related to intervention behaviors; efficacy was correlated with intervention behaviors only among chaplains. Training was associated with increased efficacy and lower levels of stigma among chaplains. Improved training may be warranted, but research needs to identify why chaplains and CAs are reluctant to refer soldiers in distress to behavioral health care.  相似文献
