男女大学生对两性嗓音源记忆的差异性研究

该项研究以两字中文词为记忆材料,以男女两种嗓音为记忆源,对20名被试进行记忆源检测.结果表明男女被试总源判断能力差异不显著;男女被试对单项源的辨别能力差异显著,表现为男性被试对男声词的辨别强于女声词,女性被试对女声词的辨别强于男声词;另外,新旧项目再认能力d'值男女被试差异不显著.     

厌恶情绪与自杀行为的关系

自杀导致人类死亡的人数与日俱增,然而自杀的心理机制却并不清楚。最近研究发现,厌恶情绪是导致自杀的主要情绪因素,个体因为自身厌恶而走向自杀。厌恶情绪是一种对自己和他人排泄物等反感的基本情绪,促进个体远离毒性和疾病,从而产生“免疫行为”。许多心理问题来自于对周围人或事物的厌恶,有自杀行为的个体对自身极其厌恶,说明他们的厌恶情绪出现了问题。如同躯体免疫攻击自身一样,自身厌恶是自杀意念的关键因素,早年创伤是其根源,生活压力和精神疾病也参与厌恶诱发自杀意念。厌恶诱发自杀意念的神经基础与HPA轴和五羟色胺系统有关。未来研究可利用神经影像和电生理等神经科学技术,检验自杀行为的神经机制,探讨厌恶情绪影响自杀行为的心理和神经机制。     

内源性注意与外源性注意的跨通道比较

该研究利用空间线索技术的实验模式,考察跨视觉和听觉通道的内源性选择注意与外源性选择性注意的相互关系。实验结果表明：(1)听觉中央线索在较长的SOA(至少500毫秒)条件下,可以引导内源性空间选择性注意;同时外周线索突现也能自动化地吸引部分注意资源。(2)听觉和视觉选择注意是分离的加工通道,但二者之间存在相互联系。     

青少年网络受欺负与抑郁：压力感与网络社会支持的作用

采用网络受欺负量表、压力感量表、网络社会支持问卷和流调中心用抑郁量表对751名初中生进行调查,考察了青少年网络受欺负与抑郁的关系、压力感在网络受欺负与抑郁间的中介作用以及网络社会支持在其中的调节作用。结果表明：（1）青少年网络受欺负与抑郁存在显著正相关;（2）压力感在网络受欺负和抑郁间起完全中介作用;（3）网络社会支持在网络受欺负事件引起的压力感与抑郁间起调节作用,压力感对青少年抑郁的影响,随网络社会支持水平的提高而降低。     

学前儿童在游戏中社交和认知类型发展的研究──中美跨文化比较

采用时间取样观察法,以录像对中美１５０名学前儿童在游戏中的社交和认知类型进行比较研究,结果表明：①学前儿童社会交往发展水平、认知发展水平、游戏难度随年龄的增长而提高;②学前儿童较高水平的认知游戏行为与较高水平的社会技能的发展相关联,社交水平与认知水平的发展相互影响;③中美学前儿童社交和认知能力发展进程具有一致性,游戏行为发展模式具有一致性;④中美学前儿童游戏的方式和内容、社交和认知水平存在显著差异,表明不同文化背景的制约性。     

The Moral Community Divide: Underage Marijuana Use Across Religious Contexts

Compared to individual‐level research on religion and marijuana use, much less research has been conducted to investigate how the overall religious context of a geographic location may influence marijuana use during adolescence and early adulthood. Using multilevel analyses on two waves of the National Study of Youth and Religion (NSYR) merged with county‐level variables from the U.S. Census and the Religious Congregations and Membership Study (RCMS), this study finds that a county's higher Catholic population share is negatively associated with underage marijuana use frequency even after controlling for a wide range of individual and county‐level variables. Besides being robust, the Catholic contextual effect on marijuana use is also diffusive, influencing both Catholic and non‐Catholic youth who live in the same county. This study highlights the importance of viewing religious influence on substance use as a contextual, cultural force across different kinds of religious moral communities.     

Associations between empathy and altruistic sharing behavior in Chinese adults

Previous research has shown that affective empathy, rather than cognitive empathy, significantly predicts people’s altruistic sharing behavior in economic games. However, most of these studies were conducted in Western populations. There might be cultural differences in the relations between empathy and altruism due to different levels of empathy between Western and Asian individuals. In this study, we measured different aspects of empathy in Chinese adults as well as their allocation offers in the dictator and ultimatum games. We found that cognitive empathy, but not affective empathy, was a significant predictor of adults’ altruistic sharing behavior in the two economic games. Subjective family income was also revealed to be a significant predictor of individuals’ altruism in the ultimatum game, such that people with lower subjective family income tended to be more generous. Potential implications of our findings are discussed.     

基于不同情绪的前瞻记忆及TAP效应的影响研究

前瞻记忆是指现在对将来某一段时间要做的行为的记忆。采用情绪图片作为诱发材料,研究了在情绪刺激下前瞻记忆任务以及前瞻记忆TAP效应的影响。结果表明:不同情绪效价主效应显著,正性情绪组成绩显著高于中性情绪组和负性情绪组; 前瞻记忆TAP效应在正性情绪和中性情绪下显著,负性情绪下部分显著; 在不同情绪效价影响下,语义—语义组、语义—知觉组、知觉—知觉组以及知觉—语义组的前瞻记忆成绩差异均存在统计学意义。     

羞怯对攻击的影响:安全感和社会比较倾向的中介作用

为考察安全感和社会比较倾向在羞怯与攻击之间关系的中介作用,采用大学生羞怯量表、社会比较倾向量表、安全感量表和攻击问卷对543名大学生进行测量。结果发现(1)羞怯、攻击和社会比较倾向三者之间呈显著两两正相关,且三者分别与安全感呈显著负相关;(2)羞怯对攻击的直接效应显著;(3)安全感和社会比较倾向在羞怯与攻击关系间起完全中介作用。     

Upward intergenerational influences on parents' innovativeness and innovation adoption: A comparative study of single‐ and multiple‐child families

In the marketing and consumer behavior literature, there has been a growing attention on upward intergenerational influences, or reverse socialization, which is largely because of children's increasing influences on family decisions. This paper hypothesizes different patterns of upward intergenerational influences in single versus multiple‐child families, controlling for peer and spousal influences. We found that young adult single children had a direct positive influence on their parents' innovation adoption behavior, but not a significant influence on their parents' overall innovativeness, whereas young adult children with siblings had a different effect: Their innovativeness had a significant positive influence on their parents' overall innovativeness, but not a direct impact on their parents' innovation adoption.
