Harvey's cognitive model of insomnia (2002a) proposes that sleep-related safety behaviors play a central role in the maintenance of insomnia because such maladaptive coping strategies are thought to reinforce threat-based appraisals of the likelihood and consequences of poor sleep. Research to date has assessed the frequency of safety behavior use in those with insomnia only; however, in addition to the frequency of occurrence, the function of safety behaviors (i.e., a belief that they will prevent a feared outcome from occurring), may be an important consideration. The purpose of this study was to examine sleep-related safety behaviors based on an expanded theoretical understanding of such behaviors across psychological disorders; that is, by examining both their frequency and perceived utility. Undergraduate students (N = 376) completed an online survey about their sleep, mood, and use of sleep-related safety behaviors. Insomnia severity was associated with a greater perceived need to use safety behaviors (i.e., utility) but not with frequency of safety behavior use. Higher perceived utility of safety behaviors was also associated with unhelpful beliefs about sleep, fear and avoidance of fatigue, and both general and sleep-specific helplessness. These results suggest that these behaviors and the associated underlying maladaptive beliefs may be important targets in cognitive behavioral therapy for insomnia. The current study extends the existing literature and refines the concept of safety behaviors in insomnia to include both the function and frequency of these behaviors. 相似文献

There is a pressing need to address prejudice, racism, and discrimination against marginalised groups in Australia. This involves change from the structural to the individual level. In this article, we discuss the merits of individual anti‐prejudice mechanisms within the Australian context. First, we expand on nine mechanisms described in a previous paper and then review five new mechanisms. We conclude that while some mechanisms are likely to be useful regardless of location, others need to be tailored to the local context. We also conclude that effective interventions need to utilise multiple mechanisms. It is hoped that the synthesis of the different mechanisms provided here will assist anti‐prejudice researchers, practitioners, and policymakers striving to improve relations among different groups in our society. 相似文献

Perfectionism is a transdiagnostic construct associated with a range of diagnoses, including depression, eating disorders and obsessive compulsive disorder. Treatments that directly target perfectionist cognitions have been shown to successfully reduce associated pathologies. However, the way in which they do this is not clear. We set out to assess the role of one candidate mechanism of action, namely the cognitive process of interpretation of ambiguity. In one experiment we looked for associations between biased interpretation and perfectionism. In a second, we manipulated interpretations, thereby providing a strong test of their aetiological significance. Results from the first experiment confirmed the presence of biased interpretation in perfectionism and demonstrated that these are highly specific to perfection relevant information, rather than reflecting general negativity. The second experiment succeeded in manipulating these perfection relevant interpretations and demonstrated that one consequence of doing so is a change in perfectionist behaviour. Together, these data experimentally demonstrate that biased interpretation of perfection relevant ambiguity contributes to the maintenance of perfectionism, but that it is also possible to reverse this. Clinical implications include the identification of one likely mechanism of therapeutic change within existing treatments, as well as identification of an appropriate evidence-based focus for future treatment development. Targeting underlying functional mechanisms, such as biased interpretation, has the potential to offer transdiagnostic benefits. 相似文献

We evaluated 2 3-component multiple-schedule sequences-a response interruption and redirection (RIRD) treatment sequence and a no-interaction control sequence-using a multielement design. With this design, we were able to evaluate the immediate and subsequent effects of RIRD on 2 participants' vocal stereotypy. For both participants, RIRD produced an immediate decrease in vocal stereotypy and did not result in a subsequent increase. 相似文献

摘要:本研究致力于探讨自上而下的任务因素对自动反应激活过程的影响。研究包含两个实验,采用掩蔽启动范式,选取字母和数字作为刺激,任务因素为与当前任务无关的处于预备状态的任务规则。实验一初步验证了与当前无关的处于预备状态的任务规则可以影响自动反应激活过程;实验二进一步证明了这种影响具有广泛性,即与当前无关的任务规则所设定的所有刺激系列都可以影响当前任务中的反应启动过程。研究总结论为:与当前任务目的无关、且存在自动刺激-反应联结的其他任务规则也能通过对被掩蔽的启动刺激反应的调节来影响对靶刺激的反应,从而影响启动效应的发生。 相似文献

自动情绪调节无需意识决定、注意加工及有意控制, 改变着情绪轨迹。迄今为止, 研究仅限于证实其确能低耗高效地改变情绪过程, 尚未对其如何改变情绪过程进行研究。以自动情绪调节的神经机制作为研究对象具有可操作性, 可从行为和心理生理层面, 对自动情绪调节改变情绪过程的机制进行实验研究。研究问题包括:1)通过EEG技术检验自动情绪调节是否影响预备阶段行为反应倾向; 2)自动情绪调节对注意的注意觉醒、注意朝向和注意执行三个阶段的作用机制; 3)自动情绪调节对评价和反应的作用机制; 4)自动情绪调节的可塑性在脑活动上的体现。最终确定自动情绪调节的加工规律, 构建其预备-注意-评价-反应模型, 并为有效控制情绪紊乱和研究出高效的情绪调节干预方案提供理论和实证依据。 相似文献

Beck抑郁认知理论认为功能失调性态度和自动思维对抑郁的形成和发展有着重要的影响, 但是不同水平的认知因素在青少年抑郁中起什么样的作用还有待于进一步的研究。根据Oei和Kwon (2007)综合认知模型(ICM), 我们假设在青少年负性生活事件和抑郁症状间功能失调性态度是调节变量, 而自动思维是中介变量。研究采用开学初和临近期末间隔近四个月两个时间点的纵向数据搜集方式, 对613名初中生施以青少年生活事件量表(ASLEC)、功能失调性态度问卷(DAS)、自动思维问卷(ATQ)以及流调中心用抑郁量表(CES-D), 然后通过路径分析对模型进行了拟合度和性别差异检验, 结果表明:(1)各变量显著相关(p<0.01), 且各变量间隔四个月两个时间点的分数差异显著(p<0.01); (2)修正后的青少年抑郁综合认知模型较好地拟了数据, 且功能失调性态度与负性生活事件的交互作用对自动思维的影响上女生的路径系数显著大于男生。结论:功能失调性态度在负性生活事件和青少年抑郁症状间起调节作用, 而自动思维从中起到了认知中介的作用, 且该模型性别差异显著。 相似文献

采用启动Stroop范式, 对刻板印象激活的无意图性及其大脑神经活动特征进行了探讨。操纵了启动和“无启动”条件以及与启动所激活的刻板印象一致、冲突和无关的3类靶子词, 记录了36名大学生被试对靶子词进行颜色判别的行为反应和脑电图(EEG, electroencephalogram)。结果发现:(1)“无启动”条件下对3类靶子的反应时基本一致; 启动条件下对一致靶子做出颜色判别的反应时显著快于对冲突靶子的, 对无关靶子的反应时介于两者之间。(2)“无启动”条件下无关靶子诱发的N400波幅最大--显著大于一致和冲突靶子诱发的, 后两者诱发的N400无差异; 启动条件下一致靶子诱发的N400波幅显著小于冲突和无关靶子诱发的N400波幅, 无关靶子诱发的N400波幅也小于冲突靶子诱发的N400波幅。这表明刻板印象激活是一个发生在知觉后加工阶段的具有无意图性的自动化加工过程, 刻板印象激活效应具有抑制冲突信息加工同时促进一致信息加工的“双刃剑”模式, N400可以作为考察这一认知过程特征的电生理学指标。 相似文献
