ENSEMBLE RECORDINGS IN AWAKE RATS: ACHIEVING BEHAVIORAL REGULARITY DURING MULTIMODAL STIMULUS PROCESSING AND DISCRIMINATIVE LEARNING

To meet an increasing need to examine the neurophysiological underpinnings of behavior in rats, we developed a behavioral system for studying sensory processing, attention and discrimination learning in rats while recording firing patterns of neurons in one or more brain areas of interest. Because neuronal activity is sensitive to variations in behavior which may confound the identification of neural correlates, a specific aim of the study was to allow rats to sample sensory stimuli under conditions of strong behavioral regularity. Our behavioral system allows multimodal stimulus presentation and is coupled to modules for delivering reinforcement, simultaneous monitoring of behavior and recording of ensembles of well isolated single neurons. Using training protocols for simple and compound discrimination, we validated the behavioral system with a group of 4 rats. Within these tasks, a majority of medial prefrontal neurons showed significant firing‐rate changes correlated to one or more trial events that could not be explained from significant variation in head position. Thus, ensemble recordings can be combined with discriminative learning tasks under conditions of strong behavioral regularity.     

Equivalents for a Quasivariety to be Generated by a Single Structure

We present some equivalent conditions for a quasivariety of structures to be generated by a single structure. The first such condition, called the embedding property was found by A.I. Mal′tsev in [6]. It says that if are nontrivial, then there exists such that A and B are embeddable into C. One of our equivalent conditions states that the set of quasi-identities valid in is closed under a certain Gentzen type rule which is due to J. Łoś and R. Suszko [5].

Youth Action Research for Prevention: A Multi-level Intervention Designed to Increase Efficacy and Empowerment Among Urban Youth

Youth Action Research for Prevention (YARP), a federally funded research and demonstration intervention, utilizes youth empowerment as the cornerstone of a multi-level intervention designed to reduce and/or delay onset of drug and sex risk, while increasing individual and collective efficacy and educational expectations. The intervention, located in Hartford Connecticut, served 114 African-Caribbean and Latino high school youth in a community education setting and a matched comparison group of 202 youth from 2001 to 2004. The strategy used in YARP begins with individuals, forges group identity and cohesion, trains youth as a group to use research to understand their community better (formative community ethnography), and then engages them in using the research for social action at multiple levels in community settings (policy, school-based, parental etc.) Engagement in community activism has, in turn, an effect on individual and collective efficacy and individual behavioral change. This approach is unique insofar as it differs from multilevel interventions that create approaches to attack multiple levels simultaneously. We describe the YARP intervention and employ qualitative and quantitative data from the quasi-experimental evaluation study design to assess the way in which the YARP approach empowered individual youth and groups of youth (youth networks) to engage in social action in their schools, communities and at the policy level, which in turn affected their attitudes and behaviors.     

社会建构论与心理学理论的未来发展

社会建构论是当代西方心理学中的一股重要学术思潮。它认为知识不是一种科学发现,而是一种社会建构。知识的生产过程不是个体理性决定的,而是一种文化历史的过程,是社会协商和互动的结果。有关心理现象的分类、心理活动的形式方面的知识都是一定文化历史条件的产物。从社会建构论的视角看心理学的研究成果会有许多新的收获。从社会建构论的观点来看,理论不是经验事实的概括和抽象,而是一种社会建构。理论先于经验观察,也高于经验观察,这种观点将理论建构置于经验工作之首,为心理学理论的未来发展开辟了全新的视角。     

Leadership and Organizational Culture: Linking CEO Characteristics to Cultural Values

Purpose  The purpose of this study was to empirically examine organizational culture theorists’ assertions about the linkages between leadership and the cultures that emerge in the organizations they lead. Specific hypotheses were developed and tested regarding relationships between chief executive officers’ (CEO’s) personality traits, and the cultural values that are shared among their organization’s members. Design/Methodology/Approach  Thirty-two CEOs completed measures of the Big-Five personality traits and personal values. A total of 467 employees across the 32 organizations completed a competing values measure of organizational culture. Findings  Results indicate support for several hypothesized relationships between CEO personality and cultural values. Exploratory analyses indicated that several CEO personal values were related to culture values. Implications  Organizations need to seriously consider the “fit” between the current or desired organizational culture and CEO characteristics. Organizations attempting to change fundamental aspects of its functioning may need significant behavioral—or personnel—changes at the top of the organization in order to achieve those changes. Originality/Value  This is the first empirical study to establish a link between specific CEO characteristics and the cultural values of their organizations. This study provides evidence that CEO characteristics are felt throughout the organization by impacting the norms that sanction or discourage member behavior and decision making, and the patterns of behavior and interaction among members.     

Personality traits of Russians from the observer's perspective

Data were collected by the members of the Russian character and personality survey from 39 samples in 33 administrative areas of the Russian Federation. Respondents (N = 7065) identified an ethnically Russian adult or college‐aged man or woman whom they knew well and rated the target using the Russian observer rating version of the Revised NEO Personality Inventory, which measures neuroticism, extraversion, openness to experience, agreeableness and conscientiousness. Factor analyses within samples showed that the factor structure of an international sample combining data from 50 different cultures was well replicated in all 39 Russian samples. Sex differences replicated the known pattern in all samples, demonstrating that women scored higher than men on most of the neuroticism, openness, agreeableness and conscientiousness facet scales. Cross‐sectional analyses demonstrated consistent age differences for four factors: Older individuals compared to younger ones were less extraverted and open but more agreeable and conscientious. The mean levels of traits were similar in all 39 samples. Although in general personality traits in Russians closely followed the universal pattern, some reliable culture‐specific effects were also found that future studies can help interpret.

The influence of experiences of discrimination on psychological stress: a comparison of seven immigrant groups

The aim of this study was to compare experiences of discrimination and their influence on trust in authorities and psychological distress among immigrants in Finland. A sample of 1146 immigrants, aged between 20 and 36 and representing seven immigrant groups (Russians, Ingrian/Finnish returnees, Estonians, Somalis, Arabs, Vietnamese and Turks), answered a mailed questionnaire based on traditional acculturation research as well as victim research. In accordance with our expectations, discrimination experiences in various realms of life were highly predictive of the psychological well‐being of all immigrants, as well as of lack of trust in the Finnish authorities. However, contrary to our hypotheses regarding the effects of visibility and cultural proximity, group differences in psychological distress did not correspond to the group differences observed in perceived discrimination. These results are discussed in the light of the opposing predictions concerning self‐damage effects of discrimination, made by social identity theory on the one hand and the theory on self‐protecting functions of external attributions (Crocker and Major, 1989) on the other. It is concluded that the low level of stress observed in the most visible and most culturally distant group, despite high levels of perceived discrimination, is better explained by the latter than the former.

抱怨行为的形成机制：基于质性访谈

为了解个体的抱怨行为特点,研究采用质性访谈法,分别对13位抱怨者和配对的26位倾听者进行半结构式访谈,并运用扎根理论分析程序对访谈资料进行三级编码。结果发现,抱怨行为在本质、内容、动机、对象选择、表现形式、效果以及影响因素七大方面具有一般特征;抱怨的本质是在情绪性动机或工具性动机驱使下产生的间接性行为,这些间接性行为可能会产生负能量,传递给第三者。研究从实证角度为抱怨的双重路径模型提供了证据支撑,同时也深化了对日常情景中的抱怨的认识。     

Cross‐Species Chimeras: Exploring a Possible Christian Perspective

Various entities that combine material from humans and other animals at either the cellular or subcellular level have attracted growing public interest. I explore the controversy by considering both the scientific rationale behind creating various entities that have prompted the greatest public concern and possible ethical implications. I note a number of potentially relevant biblical passages and reflect on the imago Dei and considerations of telos in order to prompt wider discussion regarding how Christians might respond to such emerging bioethical issues.     

Capturing excellence in applied settings: A participant conceptualizer and praxis explicator role for community psychologists

Community psychology faces a crisis of personpower similar to that which Albee identified in the clinical field four decades ago. It is clear that there are not, and likely never will be, a sufficient number of community psychologists to be able to provide assessment, consultation, and planned change toward facilitating an inclusive psychological sense of community and sound health and prosocial development in all settings that could benefit from such assistance. To help resolve this crisis, an expanded role for community psychologists is proposed: that of participant conceptualizer and praxis explicator. A participant conceptualizer and praxis explicator has the role not only of working within settings to understand and help conceptualize change processes but also of reflecting on action processes that are a part of the setting, of reflecting on theory, and of generating products that share relevant learnings. How action research serves as the methodology that allows the flow and interplay of theory and action to take place also is discussed. Illustrations are drawn from the work of Leonard Bernstein, Jim Henson and Kermit the Frog, and the author's work in area of school-based social competence promotion. This article is based on much further reflection after my Distinguished Contribution to Practice in Community Psychology award address at APA in Toronto, August 1993. The latter was designed as a talk and featured musical excepts from Leonard Bernstein and Kermit the Frog, who also made an appearance at the talk and spoke briefly. A tape of the talk can be obtained from APA, for the curious. I think of my work as a public corporation, shares of which belong to many colleagues, friends, and mentors, far too numerous to mention. I give special thanks to Jim Kelly and Ed Trickett, to Irma Serrano-Garcia and Jim Dalton, to Emory Cowen and Roger Weissberg, to George Spivack and Myrna Shure, to Jack Chinsky and George Allen, to Tom Schuyler and to my parents, to those who generously shared selective truths about me that Jim Kelly compiled into marvelous and deeply appreciated introductory comments, and to my chief shareholders, my family, Ellen, Sara, and Samara, whose daily love, patience, and support I am honored to receive.
