人脑加工自我参照任务的时空特点:来自ERP的证据

以自我参照加工任务为范式,实验采用事件相关电位(ERP)技术,探讨了自我参照加工中符合判断和不符合判断加工的时间进程和大脑神经机制。结果发现,自我参照加工在时间上可以概括分为三个阶段:注意分配阶段N1(80~150 ms)波幅出现自我参照结果的差异;语义整合阶段N2(250~450 ms)波幅和潜伏期出现自我参照结果的差异;评价判断阶段P3(450~700 ms)波幅和潜伏期出现自我参照结果的差异。从我们选择的大脑兴趣区激活水平上分析发现,自我信息在大脑中的激活似乎是一个由右及左,由后及前再及后的动态变化过程。研究结果丰富了自我参照加工的已有结果,并且对未来研究具有一定的启示意义。     

考试焦虑者注意偏向的认知与神经机制

应用情绪版本的外部线索任务,以高中生为研究对象,探讨考试焦虑的产生是由负性刺激的警觉还是脱离困难导致的认知神经机制,以及这种注意偏向(警觉与脱离成分)发生的具体时间进程。行为实验结果发现,相比起低考试焦虑个体,高考试焦虑个体对考试相关威胁刺激存在注意脱离困难。脑电实验结果中,P1成分揭示高考试焦虑者对考试相关和无关威胁线索后靶刺激的注意处理削弱;考试相关威胁线索后靶刺激诱发的P300对于高、低考试焦虑者具有临床鉴别的潜力。     

Burger or yogurt? Indulgent consumption in impression management contexts

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public.     

Determinants of Standard Errors of MLEs in Confirmatory Factor Analysis

This paper studies changes of standard errors (SE) of the normal-distribution-based maximum likelihood estimates (MLE) for confirmatory factor models as model parameters vary. Using logical analysis, simplified formulas and numerical verification, monotonic relationships between SEs and factor loadings as well as unique variances are found. Conditions under which monotonic relationships do not exist are also identified. Such functional relationships allow researchers to better understand the problem when significant factor loading estimates are expected but not obtained, and vice versa. What will affect the likelihood for Heywood cases (negative unique variance estimates) is also explicit through these relationships. Empirical findings in the literature are discussed using the obtained results.     

Investigating the mediating role of self-construal on the relationship between cultural group (Malay and Australian) and the characteristics and functional use of autobiographical memory

ABSTRACT

Cultural differences in autobiographical memory characteristics and function have often been presumed to be associated with different cultural beliefs related to the self. The current research aimed to investigate whether self-construal mediated the relationship between cultural group and the characteristics and functional use of autobiographical memory. Caucasian Australians (n?=?71) and Malay Malaysians (n?=?50) completed an online questionnaire that included the Self-Defining Memory task, the Thinking About Life Experiences Revised Questionnaire and the Self Construal Scale. As expected, the Australian group provided longer, more autonomously oriented, specific memories than the Malay group. However, contrary to our predictions, self-construal did not mediate the relationships between cultural group and memory characteristics. The Malay group reported more frequently using autobiographical memories for self-continuity than the Australian group. Finally, there was support for an indirect pathway between cultural group and use of autobiographical memories for self-continuity and social-bonding through self-construal (i.e. independent self relative to interdependent self). The findings highlight the importance of explicitly examining values assumed to be associated with autobiographical remembering, and relating these values to memory characteristics and function.

The State,Not the Trait,of Nostalgia Increases Creativity

Nostalgic experience evokes emotions and activates the cognitive process of recalling and reconstructing information in memory. This study investigated the effects of nostalgia on creativity using experiments and questionnaires. Two-hundred-and-eighty university students were randomly assigned to experimental and control groups, in which participants received and completed different writing tasks (nostalgic experience vs. common life experience). They also responded to questionnaires measuring personality, nostalgia proneness, and creativity. Results showed that participants who were primed with nostalgic experience demonstrated higher creativity than the control group. In both groups, women demonstrated higher creativity than men. When specific aspects of the nostalgic experience were used to predict creativity, results showed that: (a) nostalgia triggered by social interaction and negative affect was positively related to creativity; (b) nostalgic experience containing tangibles positively predicted creativity; (c) the total number of triggers and the amount of, but not the positivity or salience of self in, nostalgia narrative contributed positively to creativity; and (d) higher agreeableness and openness, but not nostalgia proneness or other personality traits, were associated with higher creativity. Implications for both research and practice are discussed.     

How Speech Modifies Visual Attention

Auditory distractions can have serious consequences in critical situations such as driving. Mobile phones, radios, media players, and information devices that interpret and produce speech are increasingly common in vehicles, but the threats to visual attention are not yet fully understood. In three experiments, we found that most speech tasks had relatively small adverse effects on the detection of a briefly presented target among distractors across a 60° subarea of the visual field. Although there was a little impact on detectability, moderately difficult speech tasks slowed responding relative to silence. Our most demanding condition—generating and speaking a word beginning with the last letter of another word—had the greatest effects on accuracy and latency, with responding slowed by about 900 ms. An impairment of this magnitude presents a significant threat to safe driving and calls into question the belief that hands‐free voice‐controlled devices are the answer to the problem of driver distraction.

Burnout and its relations with basic psychological needs and motivation among athletes: A systematic review and meta-analysis

ObjectivesThe present study is a review on studies about the relationships between the three basic psychological needs/motivational regulations (i.e., amotivation, controlled regulation, extrinsic autonomous regulation, and intrinsic motivation) and burnout.DesignA systematic review and meta-analysis.MethodStudies were identified through five electronic databases and manual search using combinations of three groups of keywords. Three inclusion criteria were then used to screen the searched articles.ResultsEighteen studies met the inclusion criteria and these studies varied considerably in terms of their study characteristics (e.g., characteristics of participants, study designs, and outcome measures). The results also showed that the three basic psychological needs, intrinsic motivation, extrinsic autonomous regulation, and amotivation had small to large effects on predicting global burnout and its three dimensions. However, controlled regulation showed no or weak correlations with the burnout subscales.ConclusionsSelf-determination theory was generally supported in explaining athlete burnout.     

The role of religion in moderating the impact of life events on material life goals: some evidence in support of terror management theory

How would religion and a life event carrying an existential threat (LEET) jointly impact a person's life goals of becoming wealthy and successful in one's career? Goal reprioritisation, socioemotional selectivity, and gerotranscendence theories predict a shift away from material goals following a LEET, independent of the effect of religion. However, terror management theory (TMT) predicts that the effect of death thoughts depends on one's prevailing cultural values. As religion can be regarded as a culture, it is possible that Christians' and non-believers' material life goals would be differentially altered by LEET. Data from 1259 young Chinese adults reveal no main effect of LEET, but a strong effect of religion. Moreover, there was an interaction effect between LEET and religion on material life goals: LEET weakened material goals for Christians but not for non-believers. These findings suggest that TMT is more suitable than the other theories for predicting life goal changes.
