无意识信息的刺激表征及其时间特性

无意识信息是否存在刺激表征有待解决。实验采用字母Flanker任务, 通过目标和flanker在刺激水平和反应水平上的冲突效应, 重点考察阈下flanker在刺激水平的表征。在相同的实验设计下, flanker可觉察时(实验1A), 观察到经典的刺激冲突效应和反应冲突效应; 而flanker无意识时(实验1B), 重复了反应冲突效应, 却观察到刺激冲突效应发生反转, 提示了无意识信息的反应加工及刺激加工。实验2采用符号材料促使刺激−反应的自动联结, 减少刺激−反应规则的难度, 结果重复了实验1B的发现--无意识信息引起反转的刺激冲突。刺激冲突下反转效应的一致结果表明无意识信息的刺激表征影响了认知加工。实验3考察这种影响在时间进程上的特点。无意识刺激表征的影响随反应时变化：在快速反应中观察到刺激冲突效应, 之后该效应发生反转且反转量随反应时增加而增大。相反, 无意识反应表征的影响在不同反应时下保持稳定。以上结果提供了无意识信息存在刺激表征的行为学证据并揭示了其时间特性, 提供了无意识领域中不一致研究结果的整合思路。     

Y-Balance Test Performance and Leg Muscle Activations of Children with Developmental Coordination Disorder

This study compared Lower Quarter Y-Balance Test (YBT-LQ) performance and leg muscle kinetics between children with and without developmental coordination disorder (DCD), and investigated the association between YBT-LQ performance and muscle kinetics in children with DCD. Forty-eight children with DCD and 51 children without DCD participated in the study. Leg muscle kinetics were measured using surface electromyography when performing YBT-LQ. Children with DCD exhibited an overall lower YBT-LQ scores than controls. They had a lower peak gastrocnemius medialis activation for YBT-LQ posteromedial direction and shorter duration for the muscle to reach peak torque for YBT-LQ anterior direction. No relationship was found between YBT-LQ performance and leg muscle activations in children with DCD. Children with DCD exhibited a less competent YBT-LQ performance with atypical neuromuscular control.     

Associations of depression,anxiety and PTSD with neurological disability and cognitive impairment in survivors of moyamoya disease

Depression, anxiety and posttraumatic stress disorder (PTSD) are common complications of cerebrovascular diseases. However, they were seldom explored in Moyamoya Disease (MMD) survivors. In this study, we measured the prevalence of depression, anxiety and PTSD in MMD survivors. We evaluated the association of mental disorders with neurological disability and cognitive impairment, and further find out the independent protective and risk factors of neurological disability and cognitive impairment. In MMD survivors, the prevalence of these three mental disorders is high, 46.7% for depression, 50% for anxiety and 47.5% for PTSD. Anxiety and PTSD were significantly associated with more severe neurological disability (p = 0.039 and < 0.001); depression and anxiety were significantly associated with greater cognitive deficiency (p = 0.004 and 0.002). We further found PTSD was the only risk factor associated with neurological disability, and the corresponding odds ratio (OR) and 95% confidence interval (CI) was 81.74 (9.91–674.17); depression and anxiety were risk factors associated with cognitive impairment, and the corresponding OR and 95%CI were 2.73 (1.10–6.81) and 3.37 (1.29–8.78). Therefore, these three mental disorders were associated with more severe neurological disability and greater cognitive deficiency in MMD survivors.     

The potential mediating role of anxiety sensitivity in the impact of mindfulness training on anxiety and depression severity and impairment: A randomized controlled trial

The benefits of mindfulness-based interventions to alleviate anxiety and depression have been supported by many studies. Given the effectiveness of mindfulness-based interventions on anxiety and depression, the underlying mechanisms need to be explored. Using a randomized waitlist-controlled design, this study investigated whether anxiety sensitivity was a potential mechanism for the impact of mindfulness training on anxiety and depression. Participants with high psychological distress were randomly assigned to an eight-week mindfulness intervention (N = 35) or a wait-list control group (N = 34). Before and after the intervention or corresponding waitlist period, participants completed measures of anxiety and depression severity and impairment and anxiety sensitivity. Separate mixed ANOVA demonstrated significant group (intervention vs. control group) × time (pre- vs. post-test) interactions for anxiety sensitivity and overall anxiety severity and impairment and marginally significant interaction for overall depression severity and impairment. Moreover, simple mediation models showed that reductions of anxiety sensitivity from pre- to post-test mediated the impact of mindfulness training on changes in anxiety and depression severity and impairment. The findings suggest that anxiety sensitivity is a potential mechanism underlying the effect of mindfulness training on anxiety and depression, which provides a new perspective for the study of processes of change of mindfulness-based interventions.     

Emotion suppression in multiple social contexts and its effects on psychosocial functioning: An investigation with Chinese samples

The present study examines the psychosocial consequences of emotion suppression and the moderating effect of social context in the link between emotion suppression and psychosocial functioning with two samples of Chinese undergraduate students. Suppression of happiness and sadness in five social contexts (with family members, close friends, classmates, teachers and strangers) and psychosocial functioning were investigated. The results indicate that the general level of happiness suppression negatively predicted individuals' psychosocial functioning, while sadness suppression was positively associated with psychosocial functioning. The moderating effect of social context was significant in the association between happiness suppression and psychosocial functioning, while its moderating effect was not significant for sadness. Moreover, the context differentiation (CD) of happiness suppression positively predicted psychosocial functioning, while the effect of CD of sadness suppression was not significant. The results of the present study extend the existing literature by suggesting the importance of taking social context and the specific type of emotion into account when examining the psychosocial adaptation of emotion suppression. New findings were also added to understand the effects of emotion suppression on psychosocial functioning for Chinese people. In the Chinese cultural context, which emphasizes regulating one's behaviours based on situational requirements, low levels of happiness suppression and high levels of sadness suppression appeared to be a psychosocially adaptive emotional display pattern.     

Differential relations of narcissism and self‐esteem to romantic relationships: The mediating role of perception discrepancy

Recent research has suggested that narcissism and self‐esteem, though correlated, are qualitatively different. Little research, however, has examined narcissism and self‐esteem simultaneously to test their unique contributions. The aims of this study are twofold: to examine the unique contributions of narcissism and self‐esteem to romantic relationships, and to test the mediating role of perception discrepancy (PD) in these relationships. One hundred and three pairs of dating couples in Hong Kong were recruited to complete measures of narcissism, self‐esteem, relationship satisfaction and PD. Results from actor–partner interdependence modeling (APIM) indicate that narcissism had significant negative associations with both self‐ and partner‐reported relationship satisfaction, whereas the effects of self‐esteem were generally positive. In subsequent actor–partner interdependence mediation modeling (APIMeM), in which PD was used as the mediator, narcissism and self‐esteem continued to show differential relations to both the outcomes and the mediators. In particular, narcissism had positive actor effects on PD, which further negatively predicted both self‐ and partner‐reported relationship satisfaction. In contrast, the predictive effects of self‐esteem were reversed and weaker. Implications of the findings for research and practice are discussed.     

EAST ASIA AND HUMAN KNOWLEDGE—A PERSONAL QUEST

This essay is a reflection on the ways we understand East Asia, as well as how East Asia is related to our knowledge construction. In spite of the personal tone, which I use strategically to formulate arguments in a carefully designed narrative flow, the article remains critical throughout and its conclusion is clear: exploration of the essence of East Asian civilization can constitute a meaningful effort to reevaluate and even restructure our current world of knowledge.     

Vertical vs horizontal bullying: A need of socio‐interactive ethical trainings at workplace

Bullying at workplaces is a growing problem associated with several antecedents and outcomes of psychological disorders. Extant literature shows the relationship of victimization with the owning‐up curriculum to confront bullying, but so far there is little research to cure the issue of bullying through ethics and there is no study to check the impact of ethical lessons and exercises in training materials to curb bullying at workplace. The current paper is based on a literature review of aggression and bullying, and chiefly addresses the HR practices in rescuing the people from peer victimization. Conceptually segregating supervisor‐subordinate (vertical) and peer‐peer (horizontal) bullying psychology, this paper attempts to see what possible corrective steps can be taken by senior managers, supervisors and psychologists to resolve this critical problem through interior capacities. In this paper, we have developed three propositions for conducting a future empirical investigation in connection to a cohort study. By addressing the counterproductive/deviant behavior, the present report is likely to be beneficial for psychology scientists and HR practitioners in noticing and resolving the bullying issues at the workplace for the well‐being of employees.     

基于自我参照编码的复合反应范式：有效鉴别有罪者和无罪知情者

隐藏信息测试在司法实践中应用受限的主要原因是容易将知道犯罪相关信息的无罪知情者误判为有罪者, 因此, 需探索有效区分有罪者和无罪知情者、有罪者和无罪不知情者的测谎技术。复合反应范式(complex trial protocol, CTP)是一种能有效抵抗反测谎的隐藏信息测试, 但尚未成功用于鉴别有罪者和无罪知情者。本研究设计了可同时测量EPN和P300的基于自我参照编码的CTP, 每个试次的第一部分随机呈现探测刺激或无关刺激, 第二部分随机呈现目标刺激(自己姓名)或非目标刺激(他人姓名), 要求被试在两个部分看到刺激时均做“与我有关”和“与我无关”的反应。结果表明, 基于自我参照编码的CTP能有效区分有罪者和无罪知情者, EPN区分有罪者和无罪知情者的鉴别力优于P300, P300区分有罪者和无罪不知情者的鉴别力优于EPN。
