论文物的使用价值及其源泉

文物不同于现实物品,也不同于一般物品,文物是在时间的推移和空间的变迁中逐渐形成的。文物具有四种使用价值,即自然使用价值、审美使用价值、增值使用价值和信息使用价值,除自然使用价值之外,其余三种使用价值的发展变化都直接与时空条件有关,而与人的劳动、自然力的作用关系并不明确。因此,时空条件是文物使用价值的重要源泉。     

时间延迟对故事情境关联虚假记忆的影响

研究以故事情境短文为实验材料,探讨了即时与延时48h后虚假记忆变化表现及其与真实记忆相分离的认知神经机制。结果表明,虚假记忆在延迟48h后诱发的LPC走向比即时更正性;即时条件虚假记忆与真实记忆认知加工相分离表现在有意回想加工及额叶后提取加工阶段,延迟48h后仅表现在额叶后提取加工阶段。上述结果为虚假记忆存在随时间变化及其与真实记忆相分离提供了电生理证据。     

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.
