Hypertension differentially impacts cognition in men and women in early midlife

The current study aimed to understand how sex differences in the timing of hypertension onset contribute to early midlife risk for cognitive decline that may differ by sex and whether sex-dependent advantages in normotensive populations are influenced by the presence of hypertension. One hundred and ninety-five adults aged 45–55 from the New England Family Study underwent neuropsychological testing to assess attention, executive function, and memory. Physician-diagnosed hypertension status was self-reported via questionnaire. Mid-adulthood hypertension was associated with worse performance on measures of attention and memory, but the cognitive domains impacted varied by sex. Hypertension was associated with only attention in men, whereas in women it was associated with attention and associative and working memory. Sex differences in midlife cognitive performance found in normotensive adults were attenuated in those with hypertension. Our results underscore the importance of accounting for sex when assessing the impact of hypertension on midlife cognition that could be indicative of later decline and risk for cognitive impairment and dementia, given hypertension is an independent risk factor.     

Seeking harmony in Chinese families: A dyadic analysis on Chinese parent‒child relations

Based on Leung, Koch, and Lu’s (2002) dualistic harmony model, we examined the relations of two harmony‐seeking behaviors—harmony enhancement and disintegration avoidance—to family functioning among 177 Hong Kong Chinese adolescent?parent dyads. Structural equation modeling results showed that adolescent‐rated harmony enhancement was positively related to adolescent‐rated family functioning whereas parent‐rated harmony enhancement was positively related to parent‐rated family functioning. Disintegration avoidance, however, was not related to family functioning in the two samples. Furthermore, no significant cross‐path association between harmony‐seeking behaviors and family functioning was identified, meaning that the harmony‐seeking behaviors of adolescents and their parents did not relate to each other’s perception of family functioning. Implications of these findings to our understanding of family in Chinese culture are discussed.     

认知负荷取向下基于记忆-反应冲突的欺骗检测

欺骗检测一直是心理学的重要研究问题。基于欺骗理论的认知视角, 研究者提出欺骗检测的认知负荷取向。采用隐瞒信息测试这一测谎范式, 通过操纵认知负荷影响个体在虚假反应时的记忆-反应冲突解决过程, 考察增加认知负荷对欺骗检测的影响, 以期更好地揭示欺骗检测的认知机制。在此基础上, 以普通人群和犯罪嫌疑人为被试探查基于记忆-反应冲突的欺骗检测的行为和生理指标, 并根据获得的行为和生理指标, 采用机器学习方法进行建模, 预测个体的欺骗行为。研究结果将服务于司法、安防和人际交往等领域的欺骗检测。     

医疗纠纷非诉讼解决机制与和谐医患关系

医疗纠纷的急剧攀升与解决医疗纠纷的方式和途径较为单一、过分倚重诉讼有直接的关系。要改变医疗纠纷的现状,构建和谐医患关系,必须克服法治等于诉讼的误区,建立以法律规范为指导,以预防机制为基础,以非诉讼解决机制为主要方式,以法律诉讼为最终途径的多元化的医疗纠纷解决机制。     

时代精神与当代心理学

时代精神是一个历史时期的社会、哲学和科学发展的总体思潮,即一个时代的意识形态。它影响着一个时期的学术思想倾向。在心理学的发展史中,时代精神的影响是明显的。文章从时代精神的视角对20世纪心理学的发展做出概述,谈到20世纪初行为主义如何顺应了美国的实用主义思想而产生和发展。20世纪下半叶,知识经济的时代精神孕育了认知心理学的诞生。当前的时代精神可以称为世界的全球化,这带来了心理学的广泛交流——心理学的国际化。文章最后讨论了心理学的现代特点及可能远景。     

合作数学问题解决与心理模型建构关系研究

合作学习研究者很早就开始关注合作互动中解释的作用。Chi关于自我解释的研究表明解释是一种非常有效果的学习现象,能够起到修补和建立学习者的心理模型的作用。本研究以28名高一学生为被试,采取了两种程序的合作学习任务,研究中虽然没有发现两种程序在问题解决结果上的显著差异,但是却表现出在心理模型建构方面互动效果上的差异,或表现为同等效果下的互动次数有显著性差异。     

高校业绩津贴的心理激励模型

本研究探讨了高校业绩津贴发挥激励作用的心理模型。结果表明:收入满意感及工作压力感的交互作用是津贴制发挥激励作用的内在机制;收入满意感及工作压力感通过作用于组织认同对工作业绩有显著的正向预测作用,同时收入激励对工作业绩有直接的正向预测作用。     

A tutoring package to teach pronunciation of Mandarin Chinese characters

We examined the effects of a tutoring package (verbal modeling, prompts, and contingent praise/ Chinese conversations with the tutor) on the performance of a college student's Mandarin Chinese pronunciation. The effects of the tutoring package were analyzed using a multiple baseline design across two sets of 50 Chinese characters. The tutoring package produced improvement in the student's correct pronunciation of Chinese characters from 48% (pretutoring) to 90% (posttutoring). Results suggested that the tutoring package produced mastery pronunciation of targeted Mandarin Chinese vocalizations by a nonnative speaker.
