进化心理学择偶心理机制假设的跨文化检验

通过对404例天津和432例Boston征婚启事的内容分析,结果发现：（1）男性更关注未来异性配偶的相貌、身材信息,而女性更关注对方的资源与承诺信息,但天津男女征婚者在这两方面都表现得更为强烈;（2）男性随年龄增长,会倾向于更大程度地寻找比自己小的女性,而中美女性则较稳定;（3）Boston人的配偶选择年龄空间较天津人广;（4）在个性特质方面,天津人更关注承诺性,Boston人更关注精神性与“享乐性”。结果表明,进化心理学对男女间差异有较大解释力,但对中美之间的文化差异却缺乏足够说服力。     

大中小学生内隐序列学习的发展性研究

采用序列学习的研究范式,对大中小学生的序列反应时和序列生成成绩进行测量,结果表明:(1)大中小学生均能在序列学习中获得序列规则。(2)采用比例测量方法,大中小学生的序列反应时无显著差异。(3)大中小学生的序列生成成绩是不同的,包含成绩随着年级升高而上升,排除成绩则不随年级变化;小学生包含和排除成绩无显著差异,而中学生和大学生的差异逐渐加大。说明序列学习的意识成分随年级的升高而增加。     

老年人短时记忆特点的研究

本工作以50名青年作对照,对240名65—90岁正常老人的短时记忆特点进行了研究。结果看到:1.在逻辑故事记忆、图象自由回忆、数字广度和指向记忆四项记忆成绩上,均有随年老而衰退的明显趋势。其中除数字广度外,其他三项记忆在入老年后(65岁至90岁)有继续减退的趋势。在逻辑故事、指向记忆和总分上还见到有65岁和70岁组、75岁和80岁组成绩接近的现象;2.老年人顺背数字成绩较好,对刺激序列中末端刺激的正确回忆率较高,均说明老年人的初级记忆受损较少;3.四项记忆成绩比较,青年组故事分节分最高,然后依次为图象自由回忆、顺背数字和指向记忆,而老年组则无此明显顺序;4.文化因素对记忆成绩有明显影响。     

心理理论和语言发展的关系

大量的研究表明心理理论和语言之间存在着密切的关系,但具体关系如何,一直存在争议。文章介绍了心理理论和语言关系的新近研究,着重阐述了目前关于二者关系的两种观点： （1）心理理论和语言发展之间不仅是早期揭示的一般相关关系,而是可能存在着因果关系——或以语言为因,或以心理理论为因;（2）心理理论和语言都受第三种因素影响,如执行功能和生长环境,但这些因素是究竟如何影响心理理论和语言发展的,还需深入探讨。文章最后对该领域今后的研究提出了新的见解和思路,包括对不同语言能力间的比较研究,对二者关系的跨文化研究和毕生取向研究等     

Sexual Harassment,Racial Harassment,and Well-Being among Asian American Women: An Intersectional Approach

ABSTRACT

Harassment of Asian American (AA) women has received little attention in popular culture and academic research despite their long legacy of sexualized racial stereotyping (e.g., Geisha, sexually submissive; Shimizu, 2007) and additional risk of mistreatment due to their membership in both marginalized gender and racial groups (Beale, 1970 Beale, F. (1970). Double jeopardy: To be Black and female. In T. C. Bambara (Ed.), The Black woman: An anthology (pp. 90–100). New York: New American Library. [Google Scholar]; Settles & Buchanan, 2014 Settles, I. H., & Buchanan, N. T. (2014). Intersectionality: Multiple categories of identity and difference. In V. Benet-Martinez and Y. Hong (Eds.), The Oxford Handbook of Multicultural Identity (pp. 160–180). New York, NY: Oxford University Press, Inc. [Google Scholar]). This study addresses this dearth of research using an intersectional theoretical framework to comprehensively examine sexual and racial harassment with a sample of AA women. Results validated the underlying factor structure of the Sexual Experiences Questionnaire (Fitzgerald, Gelfand, & Drasgow, 1995 Fitzgerald, L. F., Gelfand, M. J., & Drasgow, F. (1995). Measuring sexual harassment: Theoretical and psychometric advances. Basic and Applied Social Psychology, 17, 425–445. doi:10.1207/s15324834basp1704_2[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) and the Racial Acts, Crimes, and Experiences Scale (RACES; Bergman & Buchanan, 2008 Bergman, M., & Buchanan, N. T. (2008). Development of the Racial Acts, Crimes, and Experiences Survey (RACES). Unpublished instrument. [Google Scholar]) for AA women. Additionally, our results replicated previous research indicating that participants often reported experiencing behaviors that constitute harassment, but did not label them as such. This supports the use of behavioral measures over items that require individuals to label their experiences as harassment. Finally, we examined the associations between these forms of harassment and two indicators of psychological well-being, depression, and posttraumatic stress (PTS). Our results found that gender harassment was associated with more depression, whereas unwanted sexual attention, sexual coercion, and racial harassment were associated with increased PTS. This supports the utility of including both sexual and racial harassment in providing a more nuanced understanding of AA women’s harassment experiences overall and the relationship of harassment to psychological well-being. We discuss theoretical and clinical implications of these findings.     

Alteration of cingulate long-term plasticity and behavioral sensitization to inflammation by environmental enrichment

Exposure to an enriched environment (EE) has been shown to induce cortical plasticity. Considerable amount of research is focused on the effects of EE in the hippocampus; however, effects of EE on other brain regions and the mechanisms involved are not well known. To investigate this, we induced cortical plasticity by placing mice in an EE for one month and measured the effects of EE in the anterior cingulate cortex (ACC). Here, we show that EE enhanced the expression of the plasticity gene, egr-1, in the ACC of EE animals accompanied by enhanced cingulate long-term potentiation (LTP) and decreased cingulate long-term depression (LTD). The increased NMDA receptor NR2B/NR2A subunits current ratio is associated with the plasticity seen in the ACC while total protein levels remain unchanged. Furthermore, behavioral experiments show that these mice exposed to EE demonstrate enhanced responses to acute and long-term inflammation. Our findings suggest that exposure to EE alters physiological properties within the ACC which results in enhanced responses to inflammation.     

现代性语境下人的生存境界提升问题

现代性在将自我推至无以复加程度的同时,也对自我作了片面化处理,自我成为了不依赖自然、社会和他者而独立存在的东西,进而丧失了外在的禁忌,成为自我占有、欲望至上的存在者。在无限的消费和无尽的欲望的满足过程中,自我所获得的只是一种暂时的、粗鄙的、狭隘的满足。被欲望驱使的现代人应该实现欲望的合理化,激发神圣感,提高自身的生存境界,以便在资本逻辑推动下的骚动不安的世界中寻求心灵上的宁静和思绪上的久远。

Changes in step variability of new walkers with typical development and with Down syndrome

Models of human gait are based on adult locomotion. C. E. Bauby and A. D. Kuo (2000) proposed that adults rely on passive mechanisms at the spinal level to control motion in the anteroposterior direction and rely on direct monitoring of postural control in the lateral direction. The authors' purpose in this study was to determine if that model applies to control at the onset of walking in typically developing toddlers (n = 9) and in toddlers with Down syndrome (n = 6). Their longitudinal data suggested that toddlers control gait in a distinctly different manner than adults do. An adult pattern of control emerges with experience. In addition, the effect of experience on the emergence of that pattern is magnified by task-specific early intervention. The present data support the emergence and discovery of efficient patterns of control in this fundamental human behavior.     

Mode of grasp, materials, and grooved chopstick tip on gripping performance and evaluation

This study evaluated the effects of the mode of grasping, chopstick materials, and the groove of the chopstick-tip on gripping performance of 32 participants, among whom 16 were accustomed to using chopsticks with a pliers-grasping mode and the other 16 with a scissors-grasping mode. Based on a random sequence, 8 kinds of chopsticks with different combinations (materials: bamboo, wood, plastic, and stainless steel, with and without grooves in the chopstick-tip) were used to carry out the action of gripping two different objects (peanuts and longan). The time to finish gripping 50 pieces of peanut and longan, the number which fell on the table when gripping, the subjective effort and the subjective preference were measures of efficiency of pinching for 8 kinds of chopsticks. Analysis showed that chopstick materials significantly affect time of gripping. The large object (such as longan) could be gripped more easily with the pliers-grasping mode or gripped with the grooved chopstick-tip. However, for small objects (such as peanuts), there was no significant difference in performance whether the chopstick-tip was grooved or not. A combination of bamboo chopsticks with grooved tips used with a pliers-grasping seem preferrable for more favorable gripping performance.
