Ensemble statistics as units of selection

The current study investigated whether attentional mechanisms operate on ensembles as higher-order units for selection. In Experiment 1, we presented sets of circles and asked participants to compare the mean sizes of the sets while concurrently detecting a small probe appearing at a centroid of one of the sets. We found that, both with and even without the task instruction to favour larger mean sizes, people's mean size judgement was more accurate for the sets with larger mean sizes. In addition, detection of the probe appearing in the set with the largest mean size was facilitated by a matching task instruction. However, when the task instruction favoured smaller mean sizes, mean size judgement became more accurate for the sets with smaller mean sizes. These results suggest that attentional selection can be based on ensembles. In Experiment 2, we found further evidence that attention was directed towards the centroid of an ensemble, rather than towards an individual member of the ensemble. Together, these results suggest that attentional modulation can operate at the level of ensembles instead of selecting individuals separately and that the centroid of an ensemble can be the locus of selection based on an ensemble.     

Age-related differences in the timing aspect of lumbopelvic rhythm during trunk motion in the sagittal plane

Forward bending and backward return of the human trunk in the sagittal plane are associated with a specific lumbopelvic rhythm, which consists of magnitude and timing aspects. In this study, the age-related differences in the timing aspect of lumbopelvic rhythm were investigated using the continuous relative phase method. Specifically, the mean absolute relative phase (MARP) between the thoracic and pelvic motions as well as variation in MARP under repetitive motions, denoted by deviation phase (DP), were characterized in sixty participants between 20 and 70 years old. MARP and DP were determined for trunk forward bending and backward return tasks with self-selected slow and fast paces. The MARP and DP were both smaller (p = 0.003, p < 0.001 respectively) in the older versus younger age participants with no gender-related difference. In fast versus slow pace task, the MARP was smaller (p < 0.001) only in forward bending, whereas the DP was smaller (p < 0.001) in both the forward bending and backward return. A more in-phase and more stable lumbopelvic rhythm denoted respectively by smaller MARP and DP in older versus younger individuals maybe a neuromuscular strategy to protect the lower back tissues from excessive strain, in order to reduce the risk of injury.     

Evaluation of cognitive behavior among deaf subjects with video game as intervention

Previous research on video gaming mainly focused on negative impact on users. In this study, the positive impact of action video gaming among congenitally deaf subjects is investigated. Subjects possessed high level of visual information processing capacity. A 96 h of action video game play resulted in the improvement of mean reaction time (mRT) (post = 413.21 ms, pre = 453.39 ms) and certain cognitive functions. Higher heart rate variability (HRV) subjects demonstrated faster and significant improvement in mRT (p < 0.0045) after intervention. The α and β EEG band powers were found increased in parietal (6.33%, 4.28%) and occipital (8.38%, 38%) lobes respectively. The θ band power increased in frontal (32%) and parietal (13%) lobes. These results can reflect enhancement in certain cognitive performances such as visual perception, attention, memory, and motor skills. The ratio index β/(α + θ) increased in frontal and occipital lobes while β/θ increased in frontal and temporal lobes. These results may also suggest improvements in attention processing capacity and neural activity. These results implies improvements in certain aspects of cognition among deaf subjects. However, to validate these results a further study on larger number of samples with advanced computerized cognitive battery testing can be employed.     

上海博物馆竹书《内豊》与《大戴礼记》"曾子十篇"

上海博物馆竹书《内豊》具有非常宝贵的文献价值,需要进一步的研究。关于《内豊》篇,整理者对竹简的编联可取。《内豊》附简文意体现了“中庸”的思想,值得重视。以《内豊》为参照可以看出,《大戴礼记》“曾子十篇”当与曾子及其门人密切相关。     

Initial development and validity evidence for the processes of change in Psychological Skills Training Questionnaire

ObjectivesThe purpose of this study was to create and provide validity evidence for the Processes of Change in Psychological Skills Training Questionnaire (PCPSTQ).DesignThe current study used a cross-sectional research design.MethodsFive hundred fifty nine NCAA Division I, professional, and Olympic level athletes participated in the current study. To create the PCPSTQ, an initial pool of 114 items was generated by the research team. After a content validity process, 65 items were retained for analysis. Exploratory structural equation modeling was used as an analytic strategy to identify the most appropriate factor structure for the PCPSTQ. Decisions about the most appropriate model were made using multiple fit indices. To examine the construct validity of the PCPSTQ, a series of one-way ANOVAs were conducted to examine differences in processes of change use across stage of change.ResultsIn the current study, validity evidence provided support for a 7-factor process of change measure (χ² = 325.84, p < .001; Comparative Fit Index = .971; Tucker Lewis Index = .945; Root Mean Square Error of Approximation = .037; Standard Root Mean Square Residual = .020). Results also supported the construct validity of the scale as a significant difference in process of change use across stage of change was reported for all seven processes.ConclusionsResults of the current study support the factor structure and construct validity of the PCPSTQ. It appears that the processes of behavior change reported across multiple behavior change domains might also be viable for sport psychology professionals.     

道德型领导者得到了什么？道德型领导、团队平均领导-部属交换及领导者收益

道德型领导是新近提出的一种领导理论,大量研究证实这种领导方式会对员工和组织带来积极影响。然而,在领导过程中处于主体地位的领导者从中获得了什么收益却较少受到关注。以50个工作团队的248名员工为研究对象,本研究基于社会交换理论考察了道德型领导与个体层次和团队层次上领导者收益的关系及其作用过程。跨层次分析结果表明：(1)道德型领导对个体层次的员工对领导的认知信任和情感信任,以及团队层次的团队绩效和领导者绩效均有显著正向作用;(2)团队平均领导-部属交换中介了道德型领导与下属对领导者的认知信任、情感信任以及团队绩效的关系,但在道德型领导与领导者绩效关系间无显著中介作用。本文揭示了道德型领导者在领导过程中获得的“收益”以及团队层次社会交换的中介作用,为道德型领导和团队社会交换的研究提供了启示。     

论儒学基本原理与民主政治的兼容与接轨

早期儒家思想中的一些基本原理与现代民主政治的理念是可以兼容和接轨的。儒家以代表“天意”的“民意”作为政权合法性的依据 ,符合民主政治的权力观 ;儒家的“性善论”可以用来论证民主制度的合理性 ;儒家的“中庸”从政治决策的意义上来说往往是民主程序的自然结果 ;儒家提倡的“特立独行”精神所体现的负责任的个人主义是民主政治所需要的前提。     

中庸的文化心理特征及其实践理路

中庸是中国人的核心文化心理特质,主要呈现为两种形态：理想中庸和现实中庸。对理想中庸的理论研究能够夯实现实中庸实证研究的理论基础。中庸具有相互融通的三维内涵：执两用中,用中为常道,中和可常行。中庸具有德性的本质规定性,显现为三个方面的文化心理特征：执两用中的中庸认知,执中致和的中庸情感,刚柔并济的中庸人格。中庸具有鲜明的实践品格,礼仪制度是中庸实践的客观根据,籍由观照本心所作出的道德判断是中庸实践的主观根据,择善而固执是中庸实践的现实路径。     

员工为什么乐于助人?多层次的领导–部属交换对帮助行为的影响

基于社会交换理论,以56名直属主管和274名下属的配对数据为样本,考察了多层次的领导–部属交换对个体和团队层次上的帮助行为的影响及作用过程。跨层次分析结果表明:(1)个体层次的人际公平中介了个体和团队层次的领导–部属交换对员工帮助行为的影响;(2)团队层次的人际公平氛围中介了团队平均领导–部属交换对个体和团队层次的帮助行为的影响;(3)领导–部属交换关系差异化对个体和团队层次的领导–部属交换与帮助行为之间的正向关系均具有显著的负向调节作用,即相对于较高的领导–部属交换关系差异化,较低的领导–部属交换关系差异化强化了个体和团队层次的领导–部属交换对帮助行为的影响。
