Curvilinear relationships between role stress and innovative performance: Moderating effects of perceived support for innovation

Curvilinear relationships between role stress and innovative performance were explored in a study conducted in Taiwan and mainland China. Results showed that when perceived support for innovation was low, role conflict showed a U‐shaped relationship with both self‐rated and supervisor‐rated innovative performance, which contrasts sharply with the well known inverted U‐shaped relationship between challenge stress and performance. Role ambiguity showed a similar but weaker pattern with regard to supervisor‐rated innovative performance. When perceived support for innovation was high, role conflict showed a generally positive relationship with both self‐rated and supervisor‐rated innovative performance, but role ambiguity showed no significant relationship with supervisor‐rated innovative performance. Theoretical and applied implications of these findings are discussed.     

When shared group membership signifies shared subjective experience: I-sharing and the minimal group paradigm

Ingroup favoritism is pervasive. It emerges even in the minimal group paradigm, where participants are assigned to novel groups based on seemingly insignificant characteristics. Yet many of the grouping schemes used in minimal group research may imply something significant: namely, that ingroup members will share in-the-moment subjective experience, or I-share. Two studies examine the role of inferred I-sharing in the minimal group paradigm. We found that (1) people inferred that they would I-share with ingroup members more than outgroup members; (2) inferred I-sharing increased ingroup favoritism; and (3) inferred I-sharing accounted for this ingroup favoritism. Moreover, expecting to I-share with the outgroup improved participants’ attitudes toward the outgroup. These results converge with other research suggesting that people favor ingroup members, in part, because they expect to I-share with them.     

囚徒困境决策中分离效应验证性与机制研究

Savage于1954年提出"确定事件原则"这一概念,Tversky和Slafir(1992)通过实验发现,人们在不确定条件下的决策过程中,会出现违背确定事件原则的现象,并把这种现象称为"分离效应"。尽管已经有很多对于二次赌博中分离效应的机制研究并产生很多分歧,但对于囚徒困境范式中是否存在分离效应以及其机制并没有一致的结果。本文对囚徒困境中的分离效应进行了验证性实验,虽然整体结果上与Shafir与Tversky(1992)的结论相吻合,但被试专业背景对结果有显著效应。同时,按照Lambdin和Burdsal(2007)对分离效应的操作定义,结果发现分离效应没有出现,文章对其原因进行了讨论。     

An examination of the construct validity of posttraumatic stress disorder with veterans using a revised criterion set

Ongoing concerns exist in the literature regarding the construct of posttraumatic stress disorder (PTSD) and how to best conceptualize and measure this disorder. We compared the traditional DSM-IV PTSD symptom criteria (i.e., symptoms from clusters B, C, and D) to a revised criterion set that omits overlapping mood and other anxiety symptoms on PTSD prevalence, PTSD diagnostic caseness, associated psychiatric comorbidity, functional status, and structural validity using a cross-sectional, multi-site primary care sample of 747 veterans. After removing items theorized to overlap with mood and other anxiety disorders, PTSD prevalence was identical using both criterion sets (i.e., 12%). Overall, there were few statistically significant differences in PTSD caseness, associated psychiatric comorbidity, functional status, and structural validity across the two diagnostic criterion sets. These data provide further support that removing items that overlap with other psychiatric disorders does not significantly impact the prevalence of PTSD, its associated comorbidity and functional impairment, or its structural validity. Although the revised criterion set represents a more parsimonious model, the current study findings generally support the strong construct validity of PTSD. The implications of these study findings for research and clinical practice are discussed.     

Generalizability of interest structure to China: Application of the Personal Globe Inventory

Two Chinese samples of the high school students (N=721) and the college students (N=943) were administered a translated version of the Personal Globe Inventory (PGI, Tracey, 2002), and the responses were examined with respect to their structure. Results of separate factor analyses demonstrated that there were three substantive factors: People/Things, Data/Ideas, and Prestige, similar to the structure of the PGI. The fit of the data to the PGI spherical model and the circular model of eight and six (i.e., RIASEC) types were examined using the randomized test of hypothesized order relations. The results demonstrated that the spherical model and the eight-type model fit the Chinese data equally well as data from the United States. However, unlike the Japanese results, Holland's six-type model fit the data as well as the eight-type model in the present study. No structure differences were found in the high school and the college samples or across gender within the high school and the college samples. The results support the structural validity of the PGI in Chinese applications.     

Maslow and Miller: An Exploration of Gender and Affiliation in the Journey to Competence

This article shows that although neither Abraham Maslow nor Jean Baker Miller reference each other in their writings, they are following different paths to the same conclusion: competence proceeds from connection. Miller and Maslow both describe a developmental model that applies equally to women and men. The conclusion of the authors of this article is that there is no need for separate developmental models for men and women because all self‐actualization and optimum mental health evolves from affiliation.

中年Ⅱ型糖尿病人记忆损伤特点

本研究主要探讨中年Ⅱ型糖尿病人的记忆损伤特征。研究选取病人和对照各30人,控制年龄(65岁以下。病人组平均53岁,正常组52岁)、教育水平和相关疾病等因素。测试数字符号、数字工作记忆广度、动作记忆和无意义图形再认4项认知任务。结果发现：(1)病人组数字符号测试显著低于正常组;(2)在支持性条件记忆自由回忆中,病人组在有动作演练的高语义关联和无动作演练的低语义关联项目上显著低于对照组。出现分离现象;(3)在线索回忆中,病人组与对照组差异不显著;(4)两组数字工作记忆广度、无意义图形再认的成绩无差异。根据SPT(subject—performed task)研究理论对结果进行了分析,得出结论：中年Ⅱ型糖尿病人记忆的一般性信息加工能力未表现出受损,但特异信息加工受到损伤,并可能预测随年龄及病程进行而表现出一般性信息加工能力受损。     

"实践"的内在张力与话语转换契机的开启--当代马克思主义法律理论研究新探

当代马克思主义法律理论的研究面临着从批判性导向向建设性导向的话语转换的需要。而传统马克思主义法律理论对法律规范意义的一贯抛弃态度,是实现话语转换的困难所在。本文通过回溯马克思的实践思想,发现否弃法律的规范意义并非马克思思想的固有逻辑。而籍由马克思实践思想中所蕴涵着的实践的内在张力性框架,可以把法律的规范意义容纳进来,并在此基础上开启出马克思主义法律理论研究谋求自身内部话语转换的可能和契机。     

Differential effects of alcohol on associative versus item memory

Alcohol has detrimental effects on a range of cognitive processes, the most prominent being episodic memory. These deficits appear functionally similar to those observed within the normal aging population. We investigated whether an associative memory deficit, as found in older adults, would also be evident in young adults moderately intoxicated by alcohol. Participants were shown unrelated word pairs and then tested on both their item recognition (old/new item?) and associative recognition (intact/recombined pair?). Half the participants were under the influence of alcohol whereas the other half were sober. Alcohol impaired memory performance but significantly more so for associative than for item memory. Moreover, within the alcohol group, the associative memory deficit was significantly related to the amount of alcohol consumed. The findings suggest that not all aspects of episodic memory are equally impaired by alcohol, which may have practical implications for criminal investigations involving eye witnesses who have consumed alcohol.
