焦虑与注意偏向的研究是近年来情绪与认知领域的热点。为探讨特质焦虑个体的注意偏向特点及其返回抑制能力是否受不同线索的调节, 采用特质焦虑量表筛选高特质焦虑大学生29名, 低特质焦虑大学生28名完成线索-靶子任务。要求被试在提示线索消失后, 对位置进行快而准地辨别反应, 分别探索中性和情绪性提示线索下被试的返回抑制。结果发现:(1)在中性线索条件下, 高焦虑个体平均反应时慢于低焦虑个体。(2) 在情绪线索条件下, 高焦虑个体在负性线索下的反应时小于在正性线索下的反应时; 高、低焦虑个体在各种SOA条件下均出现了返回抑制, 但各组返回抑制量受到情绪线索的调节:在正性情绪线索条件下, 两组返回抑制量没有显著差异; 在负性情绪线索下, 高焦虑个体返回抑制量显著小于低焦虑个体。这表明, (1)焦虑个体的注意偏向受到刺激信息的影响:只对负性情绪线索出现注意警觉; (2)只有在涉及负性情绪信息时高、低焦虑个体返回抑制能力才有差异, 高焦虑个体存在对负性情绪线索的抑制困难。 相似文献

基于注意控制理论,采用反向眼跳范式,邀请48名运动员参加2项实验,考察竞赛特质焦虑对抑制功能的干扰效应。实验1(25人)为单因素组间设计,探讨竞赛特质焦虑对加工效能和操作成绩的影响。结果发现,竞赛特质焦虑提高眼跳方向错误率,不影响眼跳潜伏期,部分支持竞赛特质焦虑降低加工效能的假设;竞赛特质焦虑不影响按键准确率,支持竞赛特质焦虑不影响操作成绩的假设。实验2(23人)为两因素混合设计,在压力情境下探讨竞赛特质焦虑对加工效能和操作成绩的影响。结果发现,无论是在压力还是非压力情境下,竞赛特质焦虑均提高眼跳方向错误率,延长眼跳潜伏期,但不影响按键准确率,支持压力下竞赛特质焦虑降低加工效能而对操作成绩影响效果不明显的假设。综合2项实验,竞赛特质焦虑干扰抑制功能表现为降低抑制功能的加工效能但对操作成绩的影响效果不明显。本研究提示,注意控制理论适用于解释竞技运动领域焦虑与操作表现的关系。 相似文献

本研究通过两个实验探讨了当被试主动做出与他人一致/不一致的选择行为(实验1)或看到他人做出与自己一致/不一致的选择行为(实验2)时,其选择行为的一致性是如何影响结果评价过程的。脑电数据表明在结果评价的早期阶段,无论被试是主动或被动地与他人做出相同选择,这种选择一致性都会放大输赢结果之间的差异:体现在选择一致情况下比不一致情况下诱发更大的d FRN。而在结果评价的晚期阶段,当被试先做出选择之后,看到他人做出与自己不一致的选择时(实验2),相比他人与自己选择一致时,诱发了更大的P3和LPP波幅。说明被试很可能把他人的不一致选择加工为一种冲突。因此投入了更多认知资源来加工这一结果。本研究是一个探索性的创新研究,首次从时间维度上分离了选择行为和结果反馈两个阶段,并提供了选择一致性对结果评价有影响作用的脑电证据。 相似文献

采用情绪反应性-调节图片任务,考察特质焦虑青少年在下调负性情绪反应时的神经生理变化。结果发现,从行为学数据上看,两组被试都能达到下调目标,但低特质焦虑组的调节能力较强。从脑电数据上看,在刺激呈现之后300-600ms,高特质焦虑被试在负性情绪减弱调节效应方面显著小于低特质焦虑被试。在600-1000ms,高特质焦虑被试产生的LPP显著大于低特质焦虑被试。在1000ms以后,两组被试不存在显著差异。这就表明,我国高特质焦虑青少年对情绪反应有意调节能力总体较好,但较低特质焦虑青少年而言可能存在一定滞后性。 相似文献

为探讨高特质焦虑者在前注意阶段对情绪刺激的加工模式以明确其情绪偏向性特点, 本研究采用偏差-标准反转Oddball范式探讨了特质焦虑对面部表情前注意加工的影响。结果发现: 对于低特质焦虑组, 悲伤面孔所诱发的早期EMMN显著大于快乐面孔, 而对于高特质焦虑组, 快乐和悲伤面孔所诱发的早期EMMN差异不显著。并且, 高特质焦虑组的快乐面孔EMMN波幅显著大于低特质焦虑组。结果表明, 人格特质是影响面部表情前注意加工的重要因素。不同于普通被试, 高特质焦虑者在前注意阶段对快乐和悲伤面孔存在相类似的加工模式, 可能难以有效区分快乐和悲伤情绪面孔。 相似文献

根据全市三次统考平均成绩及科任教师对学生学习能力的综合评定,选择小学三年级、五年级、初中二年级、高中二年级学生为被试(各80人),共320人。每个年级的80人中,又分别包括四种类型(每种类型20人),进行抑制控制测量。结果发现:抑制控制力与学业成绩有高度的相关,即(1)双优生两种抑制控制测试成绩最好;相反双差生的两种抑制控制测试成绩最差,二者差异非常显著。(2)两种偏科的学生的两种抑制控制测试成绩处于中等,二者有些项目差异显著,有些项目差异不显著。(3)双优生与两种偏科生相比,除个别项目之外,差异也十分显著,而两种偏科生与双差生相比有差异,但表现在两种抑制控制测试中各个项目的程度不一样。 相似文献

采用事件相关电位(ERP)技术,探讨一般线索Go/Nogo和辣食线索Go/Nogo任务过程中,辣食渴求者和非辣食渴求者的抑制控制能力。(1)行为结果显示,两组被试辣食线索的反应时和错误率无显著差异,均在任务类型上有差异,即对辣食线索的反应更慢;(2)ERP结果显示,在辣食相关线索Go/Nogo任务中辣食渴求者的N2b和P3波幅都显著小于非辣食渴求者,N2a没有差异;在一般线索Go/Nogo任务中,ERP成分没有发现显著差异。结果提示,辣食渴求者只在辣食相关线索的抑制控制能力弱于非辣食渴求者,这可能意味着他们对辣食线索抑制反应的缺失。 相似文献

Negative emotional responses to sex such as anxiety, guilt and fear tend to inhibit sexual behavior. When they are not sufficient to inhibit sexual intercourse, however, they frequently interfere with the ability to plan for, or cope with the consequences of sexual activity. More specifically, these emotional responses to sex frequently interfere with the ability to apply thoughtful and careful logic to contraceptive decision making, and thereby inhibit the use of effective methods of birth control. The current article is a review of the empirical support for emotional inhibition of contraception, and an examination of the psychological mechanisms by which these responses to sex mediate birth control behavior. 相似文献

高特质焦虑个体常表现出对威胁性刺激的选择性注意偏向的特点。然而其潜在的神经机制目前仍不清楚。通过记录高、低特质焦虑者各17名进行情绪加工时的ERP,比较了两组个体在选择性注意偏向发生的时间进程和相关的神经反应的差异。结果发现,高特质焦虑者诱发出更大的N1,进一步发现恐惧图片比中性图片诱发更大的N1;而低特质焦虑者诱发了更大的N2,特质焦虑得分越低, N2波幅越大。结果初步说明高特质焦虑者加工早期对恐惧图片分配了较多的注意资源,并且其抑制执行功能可能受损;而低特质焦虑者较晚开始区分恐惧图片和中性图片。这些结果提供了支持认知-动机模型的新证据。 相似文献

Media-multitasking involves simultaneous engagement with information streams from multiple media sources, and is most prevalent in young adults. Heavy media-multitasking has been associated with differential performance on tasks involving attentional control and working memory relative to light media-multitasking. The aim of the present study was to systematically investigate relationships between executive functions and self-reported media-multitasking. Healthy participants (N?=?112, aged 18–25, male N?=?36) completed a battery of 10 traditional executive function tasks, that included assessments of attentional inhibition, response inhibition, working memory, and cognitive flexibility. Scores on the individual executive function tasks were correlated against frequency of self-reported media-multitasking, but no significant relationships were found. Trait anxiety, however, was found to be significantly associated with greater frequency of self-reported media-multitasking. The present study found no evidence of a relationship between the frequency of self-reported media-multitasking and executive functioning. The possible reasons for this are discussed. 相似文献

The relative contribution of child and parent trait anxiety on paternal and maternal controlling behaviour was examined. Thirty-seven children, aged 8–11 years, completed two difficult Tangram puzzles, one with their father and one with their mother. Videotapes of the parent–child interactions were rated on parental control and child dependent and withdrawn behaviour. Results indicated that, opposite to expectations, higher mother and father trait anxiety was associated with lower levels of parental control, and that the relation between parent trait anxiety and parental control was curvilinear. Furthermore, a significant stronger effect between child trait anxiety and parental control was found for boys than for girls. Moreover, more child withdrawal during the parent–child interaction was related to more parental control. The findings offer new insights, which may guide future theories on child and parent anxiety and parental control. Specifically, the role of parent and child gender need further conceptualisation and research. 相似文献

Trait anxiety is a unitary construct reflecting individual differences in the tendency to experience anxious symptomatology, typically measured with questionnaires such as the Spielberger Trait Anxiety Inventory (STAI‐T). Recent research by Rudaizky, Page, and MacLeod has found evidence that two different dimensions of trait anxiety account for independent variance in trait anxiety scores. These dimensions are anxiety reactivity (AR), reflecting the probability of experiencing an anxious reaction, and anxiety perseveration (AP), reflecting the persistence of anxious symptoms once elicited. There are two key issues addressed in this study: first, the replicability of Rudaizky et al.'s findings and second, the ability of the measures of AR and AP developed by Rudaizky et al. to predict independent variance in STAI‐T scores after statistically controlling for variance shared with a measure of depression. Regression analysis determined that AR and AP do account for independent variance in STAI‐T trait anxiety scores even after statistically controlling for depression. The implications of these findings for the understanding of anxiety vulnerability are discussed. 相似文献

Trait anxiety is a relatively stable disposition reflecting an individual's tendency to experience anxious symptomatology, typically measured using questionnaires such as the Spielberger Trait Anxiety Inventory (STAI-T). While trait anxiety commonly is considered a unitary construct, recent questionnaire research suggests that two different dimensions of anxiety vulnerability account for independent variance in trait anxiety scores. These dimensions are anxiety reactivity (AR), reflecting the intensity of anxiety reactions to stressors, and anxiety perseveration (AP), reflecting the persistence of anxiety symptoms. This study investigated whether in vivo measures of these two facets independently contribute to anxiety vulnerability. Seventy-two participants were exposed to a novel stress task designed to yield measures of AR and AP. Regression analysis determined that these in vivo measures were unrelated to each other, and each accounted for independent variance in trait anxiety scores. The implications of these findings for the assessment and understanding of anxiety vulnerability are discussed. 相似文献
