词汇的获得年龄效应:ERP研究

采用听觉呈现条件下的词汇判断任务和ERP技术探讨了汉语双字词获得年龄效应。结果发现:1)在行为数据上,同晚获得词相比,早获得词的反应时更短且错误率更低。2)在ERP数据上,早获得词和晚获得词所诱发的LPC(800m s~1000m s)的平均波幅存在显著差异,同晚获得词相比,早获得词所诱发的LPC波幅更大,且这种差异主要是在中央顶区,说明获得年龄是影响汉语双字词识别的一个重要因素,获得年龄效应出现在认知加工进程的后期。     

Internet-delivered physical activity intervention for college students with mental health disorders: a randomized pilot trial

The prevalence of mental health disorders among college students is rising and the increasing rates of anxiety and depression have important societal implications. Physical activity has been proposed as an adjuvant to traditional treatment approaches (i.e. psychotherapy or pharmacotherapy), and the internet is a potentially useful means of delivering physical activity information to the college-aged population. This randomized pilot trial examined the effects of an internet-based physical activity intervention on physical activity, self-efficacy, depression, and anxiety in college students (n?=?47) receiving mental health counseling. Physical activity, depression, anxiety, exercise self-efficacy, and barriers self-efficacy were assessed at baseline and post-intervention. There was a significant time effect for physical activity, with both groups increasing their physical activity levels across the 10-week intervention but with a larger increase in the intervention condition (d?=?0.68) than the control condition (d?=?0.05). Exercise and barriers self-efficacy declined across the intervention, but more so in the control than intervention condition. Effects on depression and anxiety were nonsignificant. Finally, correlation analyses showed increases in physical activity were associated with increases in exercise self-efficacy (r?=?0.62) and barriers self-efficacy (r?=?0.63) and decreases in depression (r?=?-0.44) in the intervention condition, but not in the control condition. These results suggest that an internet-delivered physical activity intervention may be a promising approach to promoting physical activity among college students undergoing mental health counseling.     

精神运动警觉性任务在不同知觉负荷下的疲劳状态监测

精神疲劳是由于长时间的认知活动引起的一种疲劳形式,不同任务水平可能造成不同的疲劳状态。本研究采用双任务范式,利用精神运动警觉性任务(Psychomotor Vigilance Task,PVT)的不同指标,考察了不同任务水平下的视觉搜索任务引起的不同精神疲劳状态。结果发现:PVT任务的最快10%反应时指标与自评疲劳程度结果一致,随着任务持续时间的增加而增加,最快10%反应时能够反映不同任务水平条件下的疲劳状态变化。注意忽视频次指标能够反映简单任务条件下的疲劳状态变化。平均反应时指标的时间主效应和任务主效应都显著,可能是反映精神疲劳状态和任务负荷情况的综合指标。PVT任务的最慢10%反应时指标,仅仅存在显著的任务效应,可能主要体现了任务负荷状态的变化。这些结果表明,PVT任务各指标能够反映不同任务水平引起的疲劳状态的不同变化,是研究和监测不同状态下精神疲劳程度较好的任务选择。     

Intimacy and Complicated Grief among Chinese Elders Having Lost their Spouses: Mediating Role of Meaning Making

This study aims to investigate the mediating role of meaning making in the relationship between intimacy and complicated grief among bereaved elders. A sample of 352 bereaved elders in rural China participated in the study. Both the linear and quadratic effects of meaning making illustrated a model that mediated the effect of intimacy on complicated grief. Essentially, findings revealed that only high levels of meaning making predicted low levels of complicated grief. This study thereby supplements existing research about meaning-making theory.     

Relationships between Involvement in School Bullying and Quality of Life in Taiwanese Adolescents

This study aimed to examine the associations between involvement in bullying and perceived quality of life (QOL) among adolescents in Taiwan. A total of 5488 students whose grade ranged from 7 to 12 participated in this study. Their experiences of victimization by and perpetration of verbal, relational, and physical bullying (including the snatching of belongings) were assessed through using the Chinese version of the School Bullying Experience Questionnaire. The level of perceived QOL was assessed using the Taiwanese Quality of Life Questionnaire for Adolescents (TQOLA). The associations between involvement in bullying and QOL were examined using multiple regression analysis. After controlling for the effects of sex, age, and depression, victimization by verbal and relationship bullying was negatively associated with QOL on all subscales of the TQOLA except for the Family subscale. Victimization by physical bullying and the snatching of belongings was negatively associated with QOL on the Social Relationships and Pain subscales. Perpetration of verbal and relationship bullying was negatively associated with QOL on the Family, Psychological Wellbeing, and Pain subscales, but positively associated with QOL on the Social Relationships subscale. Perpetration of physical bullying and snatching of belongings was negatively associated with QOL on the Residential Environment and Personal Competence subscales, but positively associated with QOL on the Psychological Wellbeing and Pain subscales. The directions of associations between bullying involvement and QOL in adolescents vary according to the types of bullying involvement and the dimensions of QOL. The results may serve as the basis on which mental health and educational professionals can develop comprehensive need-assessment and resource-allocation strategies for adolescents who have been involved in bullying.     

Hue distinctiveness overrides category in determining performance in multiple object tracking

The visual distinctiveness between targets and distractors can significantly facilitate performance in multiple object tracking (MOT), in which color is a feature that has been commonly used. However, the processing of color can be more than “visual.” Color is continuous in chromaticity, while it is commonly grouped into discrete categories (e.g., red, green). Evidence from color perception suggested that color categories may have a unique role in visual tasks independent of its chromatic appearance. Previous MOT studies have not examined the effect of chromatic and categorical distinctiveness on tracking separately. The current study aimed to reveal how chromatic (hue) and categorical distinctiveness of color between the targets and distractors affects tracking performance. With four experiments, we showed that tracking performance was largely facilitated by the increasing hue distance between the target set and the distractor set, suggesting that perceptual grouping was formed based on hue distinctiveness to aid tracking. However, we found no color categorical effect, because tracking performance was not significantly different when the targets and distractors were from the same or different categories. It was concluded that the chromatic distinctiveness of color overrides category in determining tracking performance, suggesting a dominant role of perceptual feature in MOT.     

大学生压力和睡眠质量：反刍思维和心理韧性的链式中介作用

采用大学生压力量表、反刍思维量表、青少年心理韧性量表和匹兹堡睡眠指数量表调查684位大学生(被试平均年龄为20.26岁;SD = 1.08),探讨反刍思维和心理韧性在压力和睡眠质量之间的链式中介作用。结果表明：(1)压力对睡眠质量有显著的负向预测作用;(2)压力可通过反刍思维和心理韧性的独立中介作用及反刍思维和心理韧性的链式中介作用间接预测睡眠质量。本研究揭示了压力和睡眠质量的关系及作用机制,深化了大学生压力对睡眠质量影响的研究。     

Community identity as a mediator of the relationship between socioeconomic status and altruistic behaviour in Chinese residents

Socioeconomic status is related to altruistic behaviour, but the link between them remains controversial. The present study explored the link between socioeconomic status and altruistic behaviour, as well as the psychological mechanism between them. We recruited 1,052 residents from 34 provinces in China to investigate the relationship between socioeconomic status and altruistic behaviour and the mediating mechanism. Results showed that objective socioeconomic status was positively related to altruistic behaviour. Subjective socioeconomic status was positively associated with community identity and altruistic behaviour. Community identity mediated the relationship between subjective socioeconomic status and altruistic behaviour. The findings suggest that enhancing individuals' community identity or subjective status perception can effectively increase their altruistic behaviour.     

A Critical Survey of Some Recent Philosophical Research in China

In this paper, I survey some recent literature produced by the established Chinese philosophers who regularly publish in Chinese philosophy journals and work in Mainland China. Specifically, I review the recent research of these philosophers in two areas: Chinese Philosophy and epistemology. In each area, I focus on two topics that have caught the attention of a lot of Chinese philosophers. I argue that the Chinese philosophers’ research on these topics has two prevalent problems: (i) a lot of arguments they make are weak; (ii) they tend not to critically engage with others. I discuss a metaphilosophical objection that weak argumentation and disengagement are not vices of philosophical research. I also try to make sense of (i) and (ii) in terms of some cultural factors.
