Cognitive,Affective, and Behavioral Responses to Ingroup’s Devalued Social Status: a Field Study at a Public University

In this study based on an actual event, we examined how group members cognitively, affectively, and behaviorally respond to devaluation of ingroup’s social status. Integrating predictions from Social Identity Theory (SIT; Tajfel and Turner 1986) and Intergroup Emotions Theory (IET; Smith et al. Journal of Personality and Social Psychology, 93(3), 431–446 (2007)), we explored how appraisals about ingroup’s perceived decrease in status (i.e., stability and legitimacy of status change and permeability of group boundaries) are associated with discrete group-level emotions (e.g., anger, shame), and how those emotions in turn predict different coping strategies Blanz et al. European Journal of Social Psychology, 28(5), 697–729 (1998). Analyses of the results showed that: First, preference for each coping strategy varied according to appraisals of ingroup status, and the patterns were largely consistent with what SIT predicts. Second, different group-level emotions were reported according to appraisals of ingroup status. Third, inclusion of group-level emotions as mediators of associations between ingroup status appraisals and coping strategies significantly increased the explanatory power of the path models. In sum, this study demonstrated how the two theories on intergroup relations can be used together to offer a more detailed account of group identity management. For future direction, experimental or longitudinal designs as well as cross-cultural comparisons were suggested.     

Ridge structural equation modelling with correlation matrices for ordinal and continuous data

This paper develops a ridge procedure for structural equation modelling (SEM) with ordinal and continuous data by modelling the polychoric/polyserial/product‐moment correlation matrix R . Rather than directly fitting R , the procedure fits a structural model to R _a= R +a I by minimizing the normal distribution‐based discrepancy function, where a > 0. Statistical properties of the parameter estimates are obtained. Four statistics for overall model evaluation are proposed. Empirical results indicate that the ridge procedure for SEM with ordinal data has better convergence rate, smaller bias, smaller mean square error, and better overall model evaluation than the widely used maximum likelihood procedure.     

Cognitive effects of language on human navigation

Language has been linked to spatial representation and behavior in humans, but the nature of this effect is debated. Here, we test whether simple verbal expressions improve 4-year-old children’s performance in a disoriented search task in a small rectangular room with a single red landmark wall. Disoriented children’s landmark-guided search for a hidden object was dramatically enhanced when the experimenter used certain verbal expressions to designate the landmark during the hiding event. Both a spatial expression (“I’m hiding the sticker at the red/white wall”) and a non-spatial but task-relevant expression (“The red/white wall can help you get the sticker”) enhanced children’s search, relative to uncued controls. By contrast, a verbal expression that drew attention to the landmark in a task-irrelevant manner (“Look at this pretty red/white wall”) produced no such enhancement. These findings provide further evidence that language changes spatial behavior in children and illuminate one mechanism through which language exerts its effect: by helping children understand the relevance of landmarks for encoding locations.     

the role of career stress in the relationship between maladaptive perfectionism and career attitude maturity in south korean undergraduates

Given the central role of career stress in college students' lives, this research examined whether career stress mediated the relationship between maladaptive perfectionism and career attitude maturity in a sample of 185 undergraduate students in South Korea. The results indicated that career ambiguity stress, as measured by a career stress inventory, fully mediated the relationship between maladaptive perfectionism and career attitude maturity. That is, maladaptive perfectionism correlated with greater levels of career ambiguity stress, and greater career ambiguity stress correlated with an unconstructive level of career attitude maturity. The authors discuss the findings' implications for career counselors in college settings.     

NR3C1基因多态性及单倍型、父母教养方式对青少年焦虑障碍的影响

NR3C1参与HPA轴调节,与应激相关的身心疾病关系密切。以往针对NR3C1与焦虑障碍的研究基本以成人为考察对象,且大多关注负性生活事件等个体层面环境变量。本研究采用病例-对照设计,以238名青少年为被试(焦虑障碍117人,对照121人),旨在考察NR3C1常见位点rs6191、rs6196、rs41423247的多态性、单倍型以及父母不同类型教养方式对焦虑障碍的影响。结果表明rs6191 GG基因型、rs6196 AA基因型、rs41423247 GG基因型与低焦虑障碍风险相关。父母过多的过度保护与冷漠拒绝、父亲过少的温暖关怀可预测较高的焦虑障碍风险。rs41423247多态性与母亲温暖关怀存在交互作用:rs41423247 GG基因型只在母亲温暖关怀较多时能降低焦虑障碍风险,在母亲温暖关怀较少时与焦虑障碍并无显著相关。此外,rs6191-rs6196-rs41423247构成的单倍型GAG与低焦虑障碍风险显著关联,TGC与高焦虑障碍风险显著关联,且二者与母亲温暖关怀、母亲过度保护分别存在交互作用。未来可采用追踪研究,从表观遗传层面探讨教养方式与NR3C1影响焦虑障碍的内在机制。     

Perirhinal cortex is necessary for acquiring,but not for retrieving object–place paired association

Remembering events frequently involves associating objects and their associated locations in space, and it has been implicated that the areas associated with the hippocampus are important in this function. The current study examined the role of the perirhinal cortex in retrieving familiar object–place paired associates, as well as in acquiring novel ones. Rats were required to visit one of two locations of a radial-arm maze and choose one of the objects (from a pair of different toy objects) exclusively associated with a given arm. Excitotoxic lesions of the perirhinal cortex initially impaired the normal retrieval of object–place paired-associative memories that had been learned presurgically, but the animals relearned gradually to the level of controls. In contrast, when required to associate a novel pair of objects with the same locations of the maze, the same lesioned rats were severely impaired with minimal learning, if any, taking place throughout an extensive testing period. However, the lesioned rats were normal in discriminating two different objects presented in a fixed arm in the maze. The results suggest that the perirhinal cortex is indispensable to forming discrete representations for object–place paired associates. Its role, however, may be compensated for by other structures when familiar object–place paired associative memories need to be retrieved.Remembering an event in space often requires associating objects and their locations. Associating object and place information into a unitary event representation is believed to be a foundation of episodic memory (Cahusac et al. 1989; Gaffan 1994; Davachi 2006). It has been suggested that the hippocampus and its associated regions in the medial temporal lobe (MTL) are essential in this cognitive process, and amnesic patients with damage in the MTL structures exhibit severe deficits in associating object and place information (Smith and Milner 1981; Vargha-Khadem et al. 1997; Stepankova et al. 2004). Animal models produced by localized lesions in the hippocampus and other MTL structures also support the idea by showing that the lesioned animals are impaired in associating objects and places (Parkinson et al. 1988; Gaffan and Parker 1996; Sziklas et al. 1998; Bussey et al. 2001; Gilbert and Kesner 2003, 2004; Malkova and Mishkin 2003; Lee et al. 2005; Bachevalier and Nemanic 2008; Kesner et al. 2008; Lee and Solivan 2008). Although the theoretical importance of the MTL structures in object–place association has been well acknowledged, specific contributions of the MTL structures in object–place associative memory are poorly understood. The current study examined the role of the perirhinal cortex, one of the extra hippocampal regions in the MTL, using a behavioral paradigm previously shown to be dependent on the intact hippocampus (Lee and Solivan 2008).The literature suggests that the role of the hippocampus in the object–place paired-associate task is to put together object and place information into a unified and distinct event representation. It has been suggested that spatial information and nonspatial information (such as object information) may be streamed into the hippocampus in a relatively segregated fashion, the former information mostly fed through the medial entorhinal cortex to the hippocampus via the postrhinal cortex and the latter being fed through the lateral entorhinal cortex via the perirhinal cortex (Mishkin et al. 1997; Suzuki et al. 1997; Burwell 2000; Fyhn et al. 2004; Witter and Amaral 2004; Hafting et al. 2005; Hargreaves et al. 2005; Furtak et al. 2007; Kerr et al. 2007). In our previous study (Lee and Solivan 2008) in which rats were required to discriminate rewarding versus nonrewarding pairs of similar object–place paired associates, the hippocampal lesioned rats demonstrated severe and irrecoverable deficits. The results from the study not only corroborate the long-held view that the hippocampus associates object and place information, but also demonstrate that the hippocampus is critical for disambiguating similar object–place paired associates. However, it requires examining functions of other upstream structures of the hippocampus to conclusively assign the role of associating object and place information to the hippocampus. If, for example, lesions produced in the perirhinal cortex produce similar deficits, it would be premature to conclude that the association between object and place information uniquely occurs in the hippocampus.To elucidate the relative contributions of the MTL structures in the hippocampal-dependent object–place paired-associate task (Fig. 1), we manipulated the perirhinal cortex in the current study, one of the regions implicated as an object-information provider to the hippocampus (Knierim et al. 2006; Eichenbaum and Lipton 2008). Here we tested whether the perirhinal cortex was involved in the acquisition of new object–place paired associations. Importantly, we also tested the perirhinal cortical contributions to retrieving learned paired associates between objects and places. In the current study, the rats needed to pay attention to both object and place information. Therefore, if the perirhinal cortex is unique in its function for providing object information to the hippocampus, it is predicted that lesions in the perirhinal cortex will produce severe deficits as seen in the hippocampal lesioned animals in our previous study. A simple object-discrimination task that did not require spatial information was also employed to further examine the role of the perirhinal cortex only in specific conditions.Open in a separate windowFigure 1.Illustration of the radial arm maze and behavioral paradigms. (A) Phase 1: Two objects (Spider-Man and LEGO block) were presented on arms 3 and 5 in gray color. Only one of the objects was rewarded in arm 3 (Spider-Man) and arm 5 (LEGO block) irrespective of its locations in the choice platform. Possible configuration of objects and appropriate choices are provided for both arms. In each trial, only one arm was open in the maze and objects were available in that open arm. (B) Phase 2: For acquisition of novel object–place paired associations, a pair of new objects (Barney and Girl) was presented on arms 3 and 5. Possible locations of the objects are shown as in A. Each object was rewarded only in a particular arm (Barney in arm 3 and Girl in arm 5) irrespective of its location in the choice platform. (C) Phase 3: Illustration of the task using only one arm (arm 4) in the maze. Two new objects (Mr. Potatohead and Cylinder) were used and the Mr. Potatohead choice was rewarded regardless of its location in the choice platform.     

个人-组织匹配的概念、测量策略及应用:基于互动性与灵活性的反思

个人-组织匹配(Person-Organization Fit,简称P-O匹配)的提出契合了组织行为学中人与情境双向互动的研究趋势,同时也符合组织及其成员灵活应对动态格局的现实要求。这种以双边互动性和匹配灵活性为出发点和立足点的研究是P-O匹配的特色所在。然而,目前该领域考察呈现出淡化原有独特立意的倾向。为此,我们在梳理P-O匹配学术背景和社会背景的基础上,强调将互动性和灵活性这两点基本要求融入其概念界定、测量策略的选取及应用课题当中,是为P-O匹配特色的重拾。
