Cognitive flexibility mediates the relation between intolerance of uncertainty and safety signal responding in those with panic disorder

There is a growing literature associating anxiety disorders with an inability to inhibit defensive responding during safety conditions of threatening tasks. However, investigations on the relation between panic disorder (PD) and defensive responding to safety have yielded mixed results. A recent study from our laboratory revealed that intolerance of uncertainty (IU) moderates this association, such that only individuals with PD and a high IU exhibit heightened startle potentiation during safety. The mechanism underlying this relationship is unknown. Given that safety conditions typically alternate with periods of threat, cognitive flexibility (i.e., the ability to adjust one's habitual responding to a situation, given the input of new information) may be involved in the ongoing reappraisal of danger and adjustment of defensive responding. Thus, the present study sought to investigate whether deficits in cognitive flexibility mediate the association between IU and defensive responding to safety among a sample of 71 adults diagnosed with PD. As hypothesised, cognitive flexibility mediated the relationship between IU and heightened startle potentiation during safety conditions. This finding suggests that within this subgroup, a failure to inhibit defensive responding during safety conditions may be due to deficits in cognitive flexibility.     

When east meets west: reflections on the use of Buddhist mindfulness practice in mindfulness-based interventions

The Western mental health profession has included Buddhist practices in its clinical applications, and Buddhisms’ contribution to mindfulness-based interventions (MBIs) could be considered as one of its main inputs. However, MBIs appear to depart in some key ways from their Buddhist origins whereby it may reduce its psychotherapeutic value and affect the accurate dissemination of the Buddhas’ teachings. This paper reflects on some of these departures, by firstly discussing the term mindfulness, which, as used in the MBIs, has a more restrictive meaning than that meant by the Buddha. Secondly, this paper discusses the usefulness of MBI therapists being knowledgeable in a range of meditation techniques, rather than in only a few. And thirdly, this paper discusses the usefulness of MBI therapists having a personal mindfulness practice of ones’ own, and concludes by suggesting that an explicit acknowledgement of the Buddha in the formation of the MBIs be considered.     

Ignorance May Be Bliss, But Thought Suppression Promotes Superficial Cognitive Processing

This study examined the impact of thought suppression on the quality of cognitive processing and self-reported mood. While completing a stream-of-consciousness task about two topics sequentially, participants were either instructed to suppress negative thoughts or were given no suppression instructions. Computer-based content analyses indicated that thought suppression led to significantly less causal reasoning and discrepancy seeking. However, the suppression of negative thoughts also resulted in a more positive mood. Results suggest that thought suppression can improve mood but it comes with the cognitive cost of superficial processing.     

第二语言水平对双语者语言抑制能力的影响——来自英语–汉语单通道双语者和英语–美国手语双通道双语者的证据

采用同形异义词干扰任务考察第二语言水平对英语–汉语单通道双语者和英语–美国手语双通道双语者语言抑制能力的影响。结果发现:(1)高水平英语–汉语单通道双语者的语言抑制能力较强,但低水平英语–汉语单通道双语者与英语单语者的语言抑制能力没有显著差异,说明少量的双语经验不足以导致双语认知优势;(2)不同水平的英语–美国手语双通道双语者的语言抑制能力差异不显著。所以如此,与英语–美国手语双通道双语者不存在口语和手语的双语表征加工竞争有关。整个研究表明,双语认知优势效应与双语者的二语水平以及通道经验有关。     

初中生的社会比较对认知与情感信任的影响

本研究旨在探讨不同友谊状态下,初中生的社会比较对认知与情感信任的影响,及两种信任在社会比较与亲密度变化关系中的中介作用。有效被试为522名(M=12.87岁, SD=0.67),开学初让被试提名一位最亲密朋友,期中考试后让其比较与该好友的成绩排名并评价对好友的认知与情感信任水平,随后重新评价该好友的亲密度。结果表明:在亲密朋友(第二次依旧为最亲密的朋友)中,向下比较的情感信任高于向上比较,社会比较不影响认知信任;在普通朋友(第二次亲密度降低的朋友)中,向上比较的认知和情感信任均高于向下比较;社会比较只通过认知信任影响亲密度变化(完全中介),即相比于向下比较,向上比较时的认知信任水平较高,从而更有利于维持友谊的亲密性。     

Behavioral momentum in computer-presented discriminations in individuals with severe mental retardation

Behavioral momentum was examined in 2 individuals with severe mental retardation via within-subject manipulations of obtained reinforcer rates. Subjects performed self-paced discrimination problems presented on a touch screen computer monitor. Two different problems, Tasks A and B, alternated in blocks of 15 trials on a multiple schedule. Reinforcers were snack foods. The reinforcement schedule for Task A was continuous (fixed-ratio 1) and the schedule for Task B was continuous in some conditions and variable ratio in other conditions. Behavioral momentum was assessed in test sessions by prefeeding, presenting response-independent food, and making available alternatives to the tasks. When the obtained reinforcer rate for Task A was at least twice that for Task B, resistance to change was greater for Task A. When both reinforcer rates and response rates were a pproximately equal for the two tasks, resistance to change was approximately equal. These results are consistent with behavioral momentum effects. They extend previous findings with humans by examining momentum in self-initiated discrete-trial discrimination tasks with ratio schedules, and by isolating relative reinforcer rates as a controlling variable via within-subject manipulations.     

建构主义教学与元思维的关系:认知压力的解释

本研究采用建构主义教学评估问卷、认知压力问卷、一般元思维量表与情境元思维量表对381名学生进行测量,考察了建构主义教学与元思维之间的关系,以及一级、二级认知压力在其中的中介或解释作用。研究采用结构方程模型分析,结果显示:(1)仅考虑一级认知压力时,建构主义教学能正向预测两种元思维,一级认知压力在建构主义教学与两种元思维间皆起部分中介作用;(2)仅考虑二级认知压力时,其在建构主义教学与两种元思维间皆起完全中介作用;(3)同时加入两种认知压力时,仅二级认知压力的中介作用显著。     

欺骗识别的准确率：影响因素与提高途径

欺骗是一种常见的社会现象,通过观察他人的行为表现识别欺骗则是人们的一项重要能力。研究表明,人们的欺骗识别能力仅仅略微高于随机水平。本文关注基于行为线索的欺骗识别研究。首先,介绍欺骗识别的准确率;然后,结合Brunswik的透镜模型从欺骗线索的有效性和欺骗线索的利用两方面分析识别准确率的影响因素;并在此基础上探讨了提高识别准确率的途径。最后,对未来可能的研究方向进行展望。

Is it enough to be willing to win or do you have to be smart? The relationship between competitive worldviews,cognitive abilities,and applicant faking in personality tests

Recent research has highlighted competitive worldviews as a key predictor of faking—the intentional distortion of answers by candidates in the selection context. According to theoretical assumptions, applicants’ abilities, and especially their cognitive abilities, should influence whether faking motivation, triggered by competitive worldviews, can be turned into successful faking behavior. Therefore, we examined the influence of competitive worldviews on faking in personality tests and investigated a possible moderation of this relationship by cognitive abilities in three independent high school and university student samples (N₁ = 133, N₂ = 137, N₃ = 268). Our data showed neither an influence of the two variables nor of their interaction on faking behavior. We discuss possible reasons for these findings and give suggestions for further research.
