Cross-modal attention modulates tactile subitizing but not tactile numerosity estimation

Debate remains about whether the same attentional mechanism subserves subitizing (with number of items less than or equal to 4) and numerosity estimation (with number of items equal to or larger than 5), and evidence is scarce from the tactile modality. Here, we examined tactile numerosity perception. Using tactile Braille displays, participants completed the following three main tasks: (1) Unisensory task with focused attention: Participants reported the number (1~12) of the tactile pins. (2) Unisensory task with divided attention: Participants compared the numbers of pins across the upper and lower area of their left index fingers, in addition to reporting the number of tactile pins on their right index fingers. (3) Cross-modal task with divided attention: Participants reported the number of tactile pins and compared the numbers of visual dots across the upper and lower part of a (illusory) rectangle that overlaid the tactile stimuli. We found that performance of subitizing rather than estimation was interfered with in dual tasks, regardless of whether distractor events were from the same modality (tactile modality) or from a different modality (visual modality). Moreover, a further test of visual/tactile working memory capacity revealed that the precision of tactile subitizing, in the presence of a visual distractor, was correlated with the capacity of visual working memory, not of tactile working memory. Overall, our study revealed that tactile numerosity perception is accounted for by amodal attentional modulation yet by differential attentional mechanisms in terms of subitizing and estimation.     

进化心理学视角中的腐败行为及心理机制

腐败作为全世界普遍关注的焦点问题,不同领域学者针对腐败行为产生原因与对策进行探讨。普遍认为制度、权力、文化等因素是腐败行为产生的重要原因,个别研究涉及到腐败主体的内在心理。进化心理学从进化和适应的视角对人类行为发生及心理内在特征具有终极解释度。因此,本文在前人研究的基础上,基于进化心理学的独特视角,从个体生命史历程(如童年创伤、贫穷经历等)去揭示腐败行为产生的心理机制。

A New Second-Generation Mindfulness-Based Intervention Focusing on Well-Being: A Randomized Control Trial of Mindfulness-Based Positive Psychology

Second-generation mindfulness-based interventions (SG-MBIs) align well with positive psychology philosophy and practices, but trials of SG-MBIs have largely focused on ill-being. This study developed a mindfulness-based positive psychology (MBPP) intervention integrating positive psychology with an SG-MBI to enhance well-being. A randomized control trial was performed to compare MBPP with a waitlist condition among 138 Chinese participants. The results showed that MBPP significantly reduced negative emotions for subjective well-being and significantly improved environmental mastery for psychological well-being. Improvements in self-compassion and negative attitudes but not avoidance, mediated changes in well-being. Changes in positive emotions, positive relations, and awareness were associated with the amount of meditation practice. These findings showed that MBPP is promising for improving well-being and that the positive psychology components play important roles. Broadly, the study illustrated that positive psychology and SG-MBIs can be effectively integrated, and it supported the further application of SG-MBIs from the positive psychology perspective.

     

儿童同伴尊重的发展及社交领导性的影响: 三年追踪

对285名小学三年级和四年级儿童进行了连续三年的追踪调查,分析了儿童同伴尊重发展趋势及其在群体间的差异,探讨了社交领导性在儿童同伴尊重发展中的预测作用。结果表明：（1）童年中后期儿童与同伴之间的获得尊重与表现尊重具有显著增长趋势;（2）三年间女孩的表现尊重均高于男孩但增长速度无差异;女孩的获得尊重增长速度高于男孩;（3）儿童的社交领导性能够显著正向预测儿童同伴尊重的发展趋势。     

真实型领导对教师知识分享行为的影响:组织支持感的中介和调节作用*

为了探讨真实型领导、组织支持感和教师知识分享行为的关系,对330个有效教师样本进行研究。结果发现:(1)真实型领导对教师的知识分享行为具有显著的预测作用(β=0.494,p<0.001)。(2)组织支持感在两者之间具有部分中介作用,间接效应占总效应的44.8%。(3)组织支持感在真实型领导的下属导向、领导特质、诚实不欺和正直无私与知识分享行为的关系中起调节作用,但在循规蹈矩与知识分享行为的关系中的调节作用不显著。     

斯宾诺莎对圣经的历史批判与诠释

斯宾诺莎的<神学政治论>,在圣经诠释历史上堪称是里程碑式的著作.他通过质疑作为真理之标准与公众法律之来源的圣经,倡导思想、言说与著述的自由.他对圣经研究最具原创性的贡献,并不在于其探求真理所坚持的理性主义标准,而在于对圣经文本自身及其内容所进行的历史理解.本文将简介斯宾诺莎对圣经诠释的历史批判方法,并兼及述评.

Emotion identification across adulthood using the Dynamic FACES database of emotional expressions in younger,middle aged,and older adults

Facial stimuli are widely used in behavioural and brain science research to investigate emotional facial processing. However, some studies have demonstrated that dynamic expressions elicit stronger emotional responses compared to static images. To address the need for more ecologically valid and powerful facial emotional stimuli, we created Dynamic FACES, a database of morphed videos (n?=?1026) from younger, middle-aged, and older adults displaying naturalistic emotional facial expressions (neutrality, sadness, disgust, fear, anger, happiness). To assess adult age differences in emotion identification of dynamic stimuli and to provide normative ratings for this modified set of stimuli, healthy adults (n?=?1822, age range 18–86 years) categorised for each video the emotional expression displayed, rated the expression distinctiveness, estimated the age of the face model, and rated the naturalness of the expression. We found few age differences in emotion identification when using dynamic stimuli. Only for angry faces did older adults show lower levels of identification accuracy than younger adults. Further, older adults outperformed middle-aged adults’ in identification of sadness. The use of dynamic facial emotional stimuli has previously been limited, but Dynamic FACES provides a large database of high-resolution naturalistic, dynamic expressions across adulthood.
