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。 相似文献

ABSTRACT Misinformation often continues to influence people’s cognition even after being retracted (the continued influence effect of misinformation, CIE). The current research aimed to investigate whether the individual differences in the central executive function of WM and updating could influence the CIE of misinformation with varying relevance. The results showed that the individual differences in central executive function could significantly affect the CIE, especially for the high-relevant misinformation. While the individual differences in the updating ability had a weaker impact on the CIE in general and only negatively related to the CIE for the low-relevant misinformation. The study extends the understanding of the relationship between individual differences and the CIE from previous studies, which is in line with the mental-model-updating hypothesis, and offers a preliminary clue for identifying the persons vulnerable to the CIE of misinformation in the real world. 相似文献

采用质性和量化研究方法,探讨耐挫心理的结构及因素间关系。研究1采用质性研究方法,对23名被试进行深度访谈,结果发现:(1)耐挫心理的结构由坚信、乐观、可控和醒悟构成;(2)坚信、可控和醒悟共同影响乐观。研究2采用量化研究方法,基于研究1的耐挫心理结构编制大学生耐挫心理量表,对大学生进行施测。结果发现:(1)耐挫心理四因素结构有良好的拟合指数;(2)醒悟正向预测坚信,进而正向预测可控,最终正向预测乐观;(3)量表有良好的信度和效度。结果表明,耐挫心理的结构包含坚信、乐观、可控和醒悟四个因素;大学生耐挫心理量表符合心理测量学要求,可作为未来研究的工具。 相似文献

为探讨乳腺癌患者反刍这一认知情绪调节方式在体象和创伤后应激障碍(PTSD)、创伤后成长(PTG)之间的中介作用,采用体象量表(BIS)、认知情绪调节问卷中文版(CERQ-C)、创伤后应激障碍量表(PSS)和创伤后成长问卷(PTGI)对150名乳腺癌术后患者进行研究。结果发现:(1)乳腺癌患者的体象可以正向预测PTSD和PTG;(2)乳腺癌患者的反刍在体象和PTSD的闯入性症状、回避性症状中起中介作用,在体象与PTG中的中介作用不显著。结果表明,体象既可以正向预测乳腺癌患者的PTSD和PTG,也可以通过反刍的中介作用影响PTSD。 相似文献

荀子在《解蔽》里,对于鬼神迷信做了生动的分析批判。他说道:夏首的南边有个叫涓蜀梁的人,此人既愚而又事事恐惧。在月光明亮的晚上走路,低头见自己的影子,以为是伏在地上的鬼,仰头见自己的头发,又以为是站着的妖怪。吓得转身就跑, 回到家中,竟然惊吓而死。由此,荀子得出结论说:凡人们认为有鬼,必定是有精神恍惚、心智不清的时候留下的印象。荀子 相似文献

Cross-correlation and most other longitudinal analyses assume that the association between 2 variables is stationary. Thus, a sample of occasions of measurement is expected to be representative of the association between variables regardless of the time of onset or number of occasions in the sample. The authors propose a method to analyze the association between 2 variables when the assumption of stationarity may not be warranted. The method results in estimates of both the strength of peak association and the time lag when the peak association occurred for a range of starting values of elapsed time from the beginning of an experiment. 相似文献

Two experiments with the Stroop paradigm were conducted to investigate the role of phonological codes in access to the meaning of Chinese characters. Subjects named the ink color of viewed characters or color patches. Key items were color characters, their homophones with the same tone, homophones with different tones, and semantic associates. Apart from finding the usual Stroop interference effect, homophones produced significant interference in the incongruent condition, provided that they had the same tone as the color characters. The interference effect from homophones, however, was significantly smaller than that from color characters. Semantic associates generated an interference effect in the incongruent condition, an effect of the same magnitude as the effect from the same-tone homophones. Finally, in the congruent conditions, all the key items yielded facilitations compared to neutral controls, though the facilitation from color characters was larger than the facilitations from other types of characters. These findings suggest that phonological codes in Chinese are activated obligatorily and provide early sources of constraint in access to meaning. 相似文献

Previous studies have found that subjects diagnosed with verbal auditory agnosia (VAA) from bilateral brain lesions may experience difficulties at the prephonemic level of acoustic processing. In this case study, we administered a series of speech and nonspeech discrimination tests to an individual with unilateral VAA as a result of left-temporal-lobe damage. The results indicated that the subject's ability to perceive steady-state acoustic stimuli was relatively intact but his ability to perceive dynamic stimuli was drastically reduced. We conclude that this particular aspect of acoustic processing may be a major contributing factor that disables speech perception in subjects with unilateral VAA. 相似文献

The authors examined how individuals adapt their gait and regulate their body configuration before altering direction during walking. Eight young adults were asked to change direction during walking with different turning angles (0 degree, 45 degree, 90 degree), pivot foot (left, right), and walking speeds (normal and fast). The authors used video and force platform systems to determine participants' whole-body center of mass and the center of pressure during the step before they changed direction. The results showed that anticipatory postural adjustments occurred during the prior step and occurred earlier for the fast walking speed. Anticipatory postural adjustments were affected by all 3 variables (turn angle, pivot foot, and speed). Participants leaned backward and sideward on the prior step in anticipation of the turn. Those findings indicate that the motor system uses central control mechanisms to predict the required anticipatory adjustments and organizes the body configuration on the basis of the movement goal. 相似文献
