选择性注意的ERP研究方法

注意理论的基本问题中,关于注意过滤器的位置,存在着早期与晚期选择的长期争论;关于自动加工与控制性加工,其机制与相互作用也有待明确。采用相同感觉通路的双耳分听和跨通路等实验范式,使ERP作为注意的客观电生理指标成为可能。但此类研究,涉及注意与非注意、听觉通路与视觉通路、标准刺激与偏差刺激等复杂的实验条件,并利用不同状态之间的相减技术以及由此而来的波幅测量问题.在当前国际上许多主要的ERP实验室均未能很好解决,尚处于摸索阶段。本文针对上述问题作一介绍,以供同行参考。1实验范式——刺激的设置1.1通路内的选择…     

Role of Perceived Social Support on Depression in Chinese Adolescents: A Prospective Study Examining the Buffering Model

In response to the dearth of attempts to examine functions of perceived social support on depression in Chinese adolescents, a prospective study was conducted to examine the relationship among stressful life events, perceived social support, and depression. The present results provided support for the buffering model, indicating that the function of perceived social support in mitigating subsequent depression was prominent only under high stress levels. These results were discussed in terms of the socialized role of Chinese adolescents, as well as the function of esteem enhancement of perceived social support in alleviating depression. Reciprocal relationships between initial depression levels and subsequent levels of social support were also discussed. Possible counseling and prevention programs for Chinese adolescents are proposed.     

Correlates of coping behaviours: Internal and external resources

This study examined some possible factors that were expected to influence choices of coping strategies. They were demographic variables (age, sex, marital status, education, and family income), personality traits (extroversion, neuroticism and locus of control), perceived life stress, and received social support. Five hundred and eighty one randomly selected community adults living in Kaohsiung city were interviewed and completed questionnaires measuring the above variables. Multivariate analyses had shown that: (a) higher income and education were related to more use of ‘Seeking social resources’ and ‘Planning & hoping’ coping; (b) higher extroversion was related to more use of ‘Seeking social resources’, ‘Planning & hoping’ and ‘Emotional suppression’ coping, whereas the last was also related to higher neuroticism; (c) people with higher internal locus of control favoured ‘Planning & hoping’, but not ‘Emotional suppression’ coping; (d) perceived life stress was not related to any use of coping behaviours; however, (e) more social support was related to more use of all kinds of coping behaviours. Implications of results were discussed in the context of stress and adaptation.     

双眼立体视觉的信息加工 Ⅱ.空间滤波对双眼立体感的影响

本工作的目的是希望了解立体感形成时双眼图象空间频谱的融合规律。我们利用不同质地的两套随机点立体图对,经过不同空间频带(低通、高通、带通)的光学滤波处理,然后将滤波后的图象作各种左右眼搭配观察。得到: 1.同样滤波的立体图对均能形成立体感; 2.不同质地的立体图对,空间频带搭配相同,但观察结果并不完全相同。 3.目前我们尚不能用立体图对的两个图像的空间频带是否重叠来了解两眼融合的规律。

Why Causation Need Not Follow from Statistical Association: Boundary Conditions for the Evaluation of Generative and Preventive Causal Powers

In experimental design, a tacit principle is that to test whether a candidate cause c (i.e., a manipulation) prevents an effect e, e must occur at least some of the time without the introduction of c. This principle is the preventive analogue of the explicit principle of avoiding a ceiling effect in tests of whether c produces e. Psychological models of causal inference that adopt either the covariation approach or the power approach, among their other problems, fail to explain these principles. The present article reports an experiment that demonstrates the operation of these principles in untutored reasoning. The results support an explanation of these principles according to the power PC theory, a theory that integrates the previous approaches to overcome the problems that cripple each.     

基因芯片技术的出现及对生命科学发展的影响

对于复杂的生命系统,基因芯片技术以一种综合、全面、系统的观点来研究生命现象,打破了以往“一种疾病一个基因”的研究模式,它充分利用了生命科学、信息学等当今带头科学的成果,已成为后基因组时代生命科学研究强有力的工具。随着基因芯片技术的出现, 白质芯片等类似新技术也相继发明,生命科学研究的思维方式正经历一场深刻的改革,同时加速了生物信息、基因工业时代的到来。

FOK的线索熟悉性假说与线索熟悉性判断

这项研究对ＦＯＫ的线索熟悉性假说进行了进一步检验,该假说认为,人们是根据自已对记忆线索是否熟悉而作ＦＯＫ判断的,研究结果表明,线索熟悉性判断与ＦＯＫ判断是两种不同性质的判断,它们可以在相同的刺激模式下表现出不同的反应模式。     

Gender-Role Differences in Susceptibility to the Influence of Support Availability on Depression

Previous gender-role research on depression has revealed a consistent inverse relationship between masculinity and depression, but a non-significant relationship between femininity and depression. In light of the stronger affiliative needs for feminine individuals, received social support was speculated to moderate the relationship between femininity and depression in the present research. In a longitudinal study of a sample of Hong Kong college students, the relationships among gender-role orientation, received social support, and depression were examined. Consistent with previous findings, masculinity and androgyny were inversely related to depression. Moreover, the present study supplemented previous research by revealing that femininity was related to depression through its interaction with received social support. When the amount of received social support was increased, femininity was associated with a reduction in depression level over time. In contrast, when the amount of received social support was decreased, depression tended to increase with femininity over time. The findings are discussed in terms of their implications for the gender-role literature.
