公安民警的创伤后应激症状对执行功能的影响—基于Stroop范式的探究

公安民警常常身临应激和危险情境中,是创伤事件的易感人群,但其创伤后应激症状对执行功能的影响研究尚且缺乏。已有研究发现,具有创伤后应激症状的个体的执行功能存在缺陷,表现在对冲突信息的抑制能力受损以及对创伤相关信息的注意偏向和情绪唤起。本研究以公安民警为实验组被试,据其创伤后应激症状分为高低两组,在校大学生为对照组被试,采用Stroop范式探究创伤后应激症状对公安民警“冷”、“热”执行功能的影响。结果表明,具有创伤后应激症状的公安民警在“冷”、“热”执行功能上不存在缺陷,但仍在一定程度上受到创伤后应激症状的影响。启示对具有创伤后应激症状的公安民警进行干预时,应关注其症状的严重程度,在“热”执行功能上寻求更有效的干预方式。     

Effect of Acute Psychological Stress on Motion-in-Depth Perception: An Event-Related Potential Study

The present study explored the intrinsic event-related potential (ERP) features of the effects of acute psychological stress on the processing of motion-in-depth perception using a dual-task paradigm. After a mental arithmetic task was used to induce acute psychological stress, a collision task was used to evaluate motion-in-depth perception. The error value and average amplitude of late slow waves (SW) were significantly larger for the earlier colliding spheres’ than for the later colliding spheres. The P1 peak latency in the left occipital region was significantly shorter than that of the right occipital region in the motion-in-depth perception task. Compared to the control condition, the estimated value of residual time-to-collision and error value were significantly reduced, and the N1 peak amplitude and the SW averaged amplitude were significantly increased in the stress condition. Longer motion-in-depth time improved discrimination accuracy and decreased the investment of cognitive resources. Acute psychological stress increased behavioral performance and enhanced attention resources on the motion-in-depth perception task together with greater investment of cognitive resources.     

The lntergenerational transmission of family violence: The long-term effects of aggressive behavior

This paper examines the contention that family violence is passed down from generation to generation. The sample was primarily nonclinical and was composed of 14 clients of community guidance clinics and 82 members of a randomly selected control group. The primary hypothesis that individuals who are exposed to a high degree of physical punishment as children are more likely to resort to family violence as adults was supported. Studies of the modeling of aggression were examined to suggest factors which may mediate the hypothesized relationship. It was found that respondents who had grown up in an environment characterized by either low family warmth or high stress in combination with exposure to a high degree of parental punishment were more likely to use physical punishment in their own families. Also, family violence was more likely to be transmitted in same-sex rather than cross-sex linkages.     

An empirical study of the diathesis-stress theory of disease

One thousand, one hundred and twenty-one Jewish concentration camp survivors were compared with 367 Jewish controls who had not been in a concentration camp, and had not lost any family members in such a camp. Of interest was the mortality of camp and comparison groups, on the hypothesis that the stress of being in a camp would adversely affect inmates. It was found that former camp inmates were over twice as likely to die of cancer, coronary heart diesease, or other causes as the comparison subjects of similar age and sex composition, and that severity of stress was correlated with mortality in the expected direction. Diathesis, determined by means of a special interviewer-administrated questionnaire, was found to interact synergistically with stress in producing high mortality.     

Stressed parents: a dyadic perspective on perceived infant temperament

The study employed the actor–partner interdependence model (APIM) to test whether one parent's experiences of recent life events as more stressful (the PSS) are associated with the same parent's own (the actor effect) and the other parent's (the partner effect) perceptions of the infant temperament as more negatively and/or less positively tuned (the IBQ; n=584 parents, 292 dyads). The results indicated that the more stress one parent reported the more negatively tuned were the same parent's own, and the other parent's perceptions of the infant. Perceptions of the infant temperament were least positive for members of parent dyads who were more, relative to less, similar in the experienced stress. The associations were independent of the parent gender and the parent‐reported level of trait anxiety. The findings augment prior knowledge on the factors that steer parental perceptions, and suggest that the dyadic perspective may offer valuable insight into the dynamics of interacting within a family consisting of two biological parents and an infant.

大学生职业选择和职业价值观的调查研究

本研究通过对天津地区七所高校663名在校大学生的理想职业和“现实职业”进行问卷调查,得出以下结论:(1)大学生的理想职业与“现实职业”之间有着很大的不同,但他们在选择理想职业和“现实职业”时所用的标准却有很高的一致性.(2)“高级职员”既是大学生理想中的首选职业,又是现实中的首选职业.(3)“收入”、“充分发挥能力”、“职业中的自主程度”成为大学生择业时的主要标准.(4)大学生的理想职业和“现实职业”与其所在的学校、所学的专业科类、性别、是否临近毕业等因素都有一定的关系.     

广东汕头大学高年级学生心理健康及压力调适研究

目的研究汕头大学高年级大学生心理压力特点及心理压力的调适。方法对128名毕业班的高年级大学生进行问卷调查,分析不同专业、性别与各压力的相关性,并了解其压力调适特点。结果大学毕业生的就业压力比其它压力重,不同专业大学生之间压力程度无显著差异。结论大学毕业生压力总体上仍属于轻度压力,在压力源中就业压力占主要地位,大学校园不应忽视对毕业生的就业指导及心理辅导。     

自我超越生命意义对压力和健康关系的调节作用

研究目的是检验一个新的应激应对资源—自我超越生命意义的健康调节作用。自我超越生命意义的理论基础是东方的佛教哲学和道家哲学。研究的测量工具有：大学校园压力量表,一般健康问卷（GHQ-20）,自尊量表和自我超越生命意义量表。被试为来自北京市三所高校的788名大学生。研究结果为：自我超越生命意义可以调节应激条件下的忧郁情绪、一般健康问题和自尊,但是对于焦虑情绪和自我肯定的调节作用不明显。研究结论是：自我超越生命意义对心理健康的某些方面具有调节作用

Upsetting Behavior: Reactions to Personal and Bystander Sexual Harassment Experiences

The current research was designed to examine objective and contextual factors related to the appraisal of potentially sexually harassing situations. Working female participants (n = 208) from a mid-sized southwestern university completed a workplace experiences survey in small groups. The majority of participants were Hispanic/Latina (77.9%). We predicted that characteristics of personal harassment experiences (e.g., number of distinct types of behaviors experienced, frequency, duration) and bystander harassment experiences would contribute independently to how upset women were by their own sexual harassment experiences. Results indicated that characteristics of personal harassment experiences and bystander experiences did predict how upset women were by their own gender harassment and by unwanted sexual attention experiences. Results are discussed in terms of the importance of considering multiple types of workplace stressors (e.g., personal and bystander sexual harassment experiences) and their relation to the appraisal process.
