Gender Stereotype Activation versus Lexical Semantic Activation: An ERP Study

It is an open question whether social stereotype activation can be distinguished from nonsocial semantic activation. To address this question, gender stereotype activation (GSA) and lexical semantic activation (LSA) were directly compared. EEGs were recorded in 20 participants as they identified the congruence between prime-target word pairs under four different conditions (stereotype congruent, stereotype incongruent, semantic congruent, and semantic incongruent). We found that congruent targets elicited faster and more accurate responses and reduced N400 amplitudes irrespective of priming category types. The N400 congruency effect (i.e., the difference between incongruity and congruity) started earlier and had greater amplitude for GSA than for LSA. Moreover, gender category priming induced a smaller N400 and a larger P600 than lexical category priming. These findings suggest that the brain is not only sensitive to both stereotype and semantic violation in the post-perceptual processing stage but can also differentiate these two information processes. Further, the findings suggest superior processing (i.e., faster and deeper processing) when the words are associated with social category and convey stereotype knowledge.     

Visual arts in counselling adults with depressive disorders

This study provides a better understanding of using visual arts in counselling adults with depressive disorders. Three in-depth case studies were conducted in the counselling unit of a mental health hospital in Malaysia. Both qualitative and quantitative research methods were applied to explore three adult participants’ counselling experiences. They attended six individual counselling sessions, which included four art-making activities, and two after-session interviews, for approximately two months. Interpretative Phenomenological Analysis was used to analyse the qualitative data. The findings showed that through the therapeutic use of visual arts, the participants were able to explore and express various emotions, face their problems, communicate better with themselves and the counsellor, achieve a deeper self-understanding, and make meaningful progress in counselling, even though some of them experienced a sense of uncertainty at the beginning of some art-making activities.     

The Role of Self-Esteem and Social Support in the Relationship between Extraversion and Happiness: a Serial Mediation Model

Studies have documented that self-esteem and social support mediate the relationship between extroversion and happiness. Most of the studies, however, were conducted in a piecemeal fashion and have rarely evaluated the two mediators simultaneously. It is not clear whether the two mediating effects are equally important or one is greater than the other. Moreover, little attention has been given to the indirect effect of extraversion on happiness through self-esteem then social support (i.e., serial mediating effect). The present study attempts to bridge these gaps by proposing and testing a path model illustrating the mediating effects of self-esteem and social support on the linkage of extraversion and happiness. Undergraduate students (N = 311) completed measures of extroversion, social support, self-esteem, and happiness. Results showed that extraversion, self-esteem, and social support were significantly associated with happiness. As predicted, both self-esteem and social support mediated the relationship between extraversion and happiness, respectively. Results also supported the hypothesized serial mediating effect. In other words, extroverts tend to have high self-esteem which increases supports they receive from friends and family. The high social support, in turn, enhances happiness. Additionally, comparisons among the three indirect effects indicated that the effect of self-esteem was significantly greater than the other two effects. The findings not only shed light on the independent and accumulative mediating effects of self-esteem and social support, but also provide new insight into the difference in strength of the indirect effects.     

Childhood Adversity and Children’s Academic Functioning: Roles of Parenting Stress and Neighborhood Support

Existing research has shown that adverse childhood experiences from family instability and lack of safety increase children’s risk for poor academic functioning. A recent conceptual framework, however, has emphasized the need to investigate how parenting might mediate while community context might moderate the association between childhood adversity and children’s cognitive development. In the current study, we tested the roles of parenting stress and neighborhood support in the association between cumulative childhood adversity and children’s current academic functioning. We conducted a secondary data analysis on the subsample of school-aged children (i.e., 6–17 years old; N?=?65,680) from the 2011–2012 United States National Survey of Children’s Health (NSCH). The parent provided telephone survey data on six types of adversity (e.g., parent’s divorce) that the target child experienced, parenting stress, neighborhood support, as well as the child’s academic functioning. Controlling for the child’s age, gender, ethnicity, and the parent’s education level, structural equation modeling (SEM) revealed a significant moderated mediating effect: parenting stress partially mediated the association between history of childhood adversity and children’s current academic functioning (β?=??1.760, p?<?0.001), while neighborhood support moderated the association between parenting stress (β?=?0.492, p?<?0.001) and academic functioning.     

Organizational citizenship behavior and social loafing: the role of personality, motives, and contextual factors

The present study integrates the literature on social loafing and organizational citizenship behavior (OCB). The authors examined the roles of personality, motives, and contextual factors in influencing the work behaviors of OCB and social loafing. In a sample of 341 individuals working in project groups, with data collected over 3 time periods, the authors found that conscientiousness was negatively related to social loafing. They also found the known positive relation of OCB with conscientiousness. Felt responsibility was negatively related to social loafing. The authors found no significant relations between social loafing and OCB motives.     

Ratio of fourth to second fingertip extensions in relation to serum estradiol and testosterone levels in men and women

Sex differences in second (2D) and fourth (4D) fingertip extensions relative to the middle fingertip and 4D:2D fingertip extension ratios were studied in men and women. Body height positively correlated with index fingertip extensions, not with ring fingertip extensions, nor with their ratio. Mean 2D extension (both hands) was smaller in women than men; mean 4D extension (right hand) was smaller in men than women; 4D:2D fingertip extension ratios from both hands were larger in women than men. Serum estradiol concentration negatively correlated with 2D extensions for both hands (no significant correlation with 4D extensions), but positively correlated with 4D:2D extension ratios for both hands. Serum testosterone concentration positively correlated with 2D extensions of both hands (no significant correlation with 4D extension), but negatively correlated with 4D:2D extension ratios for both hands. These relations were also studied in men and women separately. It was concluded that the 4D:2D extension ratio was greater in women than in men; 2D and 4D extensions and 4D:2D extension ratios may be determined prenatally by sex hormones; fingertip extensions may be predictive of adult and prenatal sex hormone levels.     

Conformity: moods matter

This study examined the hypotheses that positive mood enhances conformity and that negative mood reduces it. Participants were induced to feel positive, neutral, or negative moods and then answered, in private, six mathematical questions. They observed that wrong answers were unanimously given by five bogus participants for three of the questions. Conformity was measured by whether they indicated the erroneous answers given by these bogus participants in these three questions. The results were supportive of the hypothesis. The current results are consistent with past findings about mood differences in heuristic versus elaborative processing. Copyright © 2007 John Wiley & Sons, Ltd.     

楚简《太一生水》"托其名"考

楚简《太一生水》"托其名"之"名"是天地初开时的"混沌"名。"混沌"就是"清浊"或"清混"(也作"清浑"),即《太一生水》中之"青昏"。因此,""应厘定为"青昏"而非"请问"。"托其名"就是依照贵道——原道——循道——用道的逻辑理路循序演进,对宇宙生成过程进行逆向追述,上溯至天地的源头,因"青昏"之名,循"道"之字,以行"浑沌氏之术"。这是道家"推天理以明人事"思想的体现。
