Despite global gender inequalities, findings on gender differences in subjective well-being have been inconsistent. We conducted a meta-analysis on gender differences in subjective well-being to account for the type of subjective-well-being measure, sampling variability, and levels of national gender inequality from which samples are gathered. Based on 281 effect sizes for life satisfaction ( N = 1,001,802) and 264 for job satisfaction ( N = 341,949), results showed no significant gender differences in both types of subjective well-being. Supplementary meta-analyses found significantly lower job satisfaction, but not life satisfaction, in women for studies that used both life-satisfaction and job-satisfaction measures, and studies that relied on measures that previously demonstrated measurement equivalence. Using the Gender Inequality Index, we found that greater national gender inequality significantly predicts greater gender differences in job satisfaction, but not life satisfaction. We discuss the implications of these findings and the use of subjective well-being as a measure of societal progress.

More than 20 years ago, researchers proposed that individual differences in performance in such domains as music, sports, and games largely reflect individual differences in amount of deliberate practice, which was defined as engagement in structured activities created specifically to improve performance in a domain. This view is a frequent topic of popular-science writing-but is it supported by empirical evidence? To answer this question, we conducted a meta-analysis covering all major domains in which deliberate practice has been investigated. We found that deliberate practice explained 26% of the variance in performance for games, 21% for music, 18% for sports, 4% for education, and less than 1% for professions. We conclude that deliberate practice is important, but not as important as has been argued.

This paper first reviewed the research about the selection task, the THOG problem, illusion in multiple premises deductive reasoning problem and the MHD problem, then concluded the basic hypothesis and basic methods in reasoning illusion research, and finally discussed future studies in this field.

本文介绍了行动观的主要理论观点,认为个体有意识的自我发展和自我调节对于发展具有重大意义,进而阐述了自我观察、自我评价和自我调节的过程和机制.行动观克服了哲学的决定论和因果机制的局限,把发展的多样性和规律性统一起来,并有效地整合了文化和个体自身对于发展的作用.

本文阐述了脑功能定位的具体技术及其与社会心理现象相结合的心理神经模型.这种结合的趋势有助于促进神经科学和社会心理学的发展,有助于解释社会心理现象中固有的一些具体问题.同时,由于社会心理现象的复杂性,因此并不一定都适合直接进行脑功能定位.

特定区域整合模型与信息传输接替模型提供了聋人唇读不同的大脑机制,前者认为聋人唇读是由特定大脑皮层(如STS,后扣带回等)加工的结果,听觉皮层并未参与视觉语言认知加工;后者认为聋人唇读的大脑机制与正常人无声唇读的大脑机制基本相似,是通过皮层下的连接区域(如屏状核)激活了视觉皮层、听觉皮层等.但更多的证据支持信息传输接替模型.聋人的听觉皮层具有可塑性,早期的语言经验对言语加工神经通路的建立具有很大的影响.
