情绪对内隐刻板印象表达的调节

采用IAT范式探讨不同情绪对内隐刻板印象表达的调节作用：实验1通过音乐唤醒被试的不同弥散性情绪状态(悲伤vs.愉悦), 并操纵其即时观念(刻板一致vs.刻板冲突), 探讨二者对内隐性别刻板印象表达的影响。实验2通过视频诱发被试不同的指向性情绪(同情vs.厌恶), 研究其如何调节大学生对不同感染途径的艾滋病患者和病毒携带者的内隐刻板印象表达。在此基础上引入四重模型(Quad Model)分析技术, 进一步细化情绪的调节作用究竟发生在认知加工的自动加工过程还是控制加工过程, 以及不同情绪是通过哪些心理成分调节内隐刻板印象的表达。结果表明：(1)当即时观念与刻板印象内容一致时, 积极弥散性情绪促进内隐刻板印象的表达; 反之则会抑制其表达; (2)弥散性情绪通过调节认知加工的自动化加工过程, 进而调节内隐刻板印象的表达, 但未参与调节控制性加工过程; (3)积极效价的指向性情绪会抑制被试对艾滋病患者的内隐刻板印象表达, 消极效价的指向性情绪会促进其表达; (4)指向性情绪通过自动激活成分, 调节内隐刻板印象表达的自动化加工过程; 同时也通过辨识力成分, 参与调节内隐刻板印象表达的控制性加工过程。     

Measuring model flexibility with parameter space partitioning: an introduction and application example

A primary criterion on which models of cognition are evaluated is their ability to fit empirical data. To understand the reason why a model yields a good or poor fit, it is necessary to determine the data-fitting potential (i.e., flexibility) of the model. In the first part of this article, methods for comparing models and studying their flexibility are reviewed, with a focus on parameter space partitioning (PSP), a general-purpose method for analyzing and comparing all classes of cognitive models. PSP is then demonstrated in the second part of the article in which two connectionist models of speech perception (TRACE and ARTphone) are compared to learn how design differences affect model flexibility.     

AN ANALYTIC FORM FOR THE INTERRESPONSE TIME ANALYSIS OF SHULL, GAYNOR, AND GRIMES WITH APPLICATIONS AND EXTENSIONS

Shull, Gaynor and Grimes advanced a model for interresponse time distribution using probabilistic cycling between a higher-rate and a lower-rate response process. Both response processes are assumed to be random in time with a constant rate. The cycling between the two processes is assumed to have a constant transition probability that is independent of bout length. This report develops an analytic form of the model which has a natural parametrization for a higher-rate within-bout responding and a lower-rate visit-initiation responding. The analytic form provides a convenient basis for both a nonlinear least-squares data reduction technique to estimate the model's parameters and Monte Carlo simulations of the model. In addition, the analytic formulation is extended to both a refractory period for the rats' behavior and, separately, the strongly-banded behavior seen with pigeons.     

Limited information estimation and testing of discretized multivariate normal structural models

Discretized multivariate normal structural models are often estimated using multistage estimation procedures. The asymptotic properties of parameter estimates, standard errors, and tests of structural restrictions on thresholds and polychoric correlations are well known. It was not clear how to assess the overall discrepancy between the contingency table and the model for these estimators. It is shown that the overall discrepancy can be decomposed into a distributional discrepancy and a structural discrepancy. A test of the overall model specification is proposed, as well as a test of the distributional specification (i.e., discretized multivariate normality). Also, the small sample performance of overall, distributional, and structural tests, as well as of parameter estimates and standard errors is investigated under conditions of correct model specification and also under mild structural and/or distributional misspecification. It is found that relatively small samples are needed for parameter estimates, standard errors, and structural tests. Larger samples are needed for the distributional and overall tests. Furthermore, parameter estimates, standard errors, and structural tests are surprisingly robust to distributional misspecification. This research was supported by the Department of Universities, Research and Information Society (DURSI) of the Catalan Government, and by grants BSO2000-0661 and BSO2003-08507 of the Spanish Ministry of Science and Technology.     

A spherical conceptualization of personality traits

This research utilizes the geometric structure of the two‐dimensional Interpersonal Circumplex (IPC), and adds the Five‐Factor Model (FFM) dimension of conscientiousness to create a three‐dimensional spherical model of personality; the interpersonal sphere (IPS). A sample of 250 participants was initially used to select items that conformed to the geometric locations of 26 different characteristics on the IPS. A separate sample of 251 participants confirmed the geometric structure of these characteristic measures using randomization tests. To demonstrate an application of this three‐dimensional model, the IPS was employed as a geometric taxonomy to map various personality constructs. The combined sample of 501 participants was used to cartographically locate 164 scales from the NEO Personality Inventory, (NEO‐PI‐R), the 16 Personality Factor Questionnaire (16PF), the California Psychological Inventory (CPI), the Hogan Personality Inventory (HPI), the Temperament and Character Inventory (TCI), the Multidimensional Personality Questionnaire (MPQ), and the Jackson Personality Inventory (JPI‐R) onto the IPS. The spherical conception of traits provided by the three‐dimensional IPS is discussed as both an extension of the FFM and the two‐dimensional IPC. Copyright © 2006 John Wiley & Sons, Ltd.     

National Character and Personality

ABSTRACT— People in all cultures have shared perceptions about the personality characteristics of the typical member of their own culture and of typical members of other cultures. Recent collaborative work has provided validated assessments of the personality profiles of over 50 cultures, and judged by these criteria, perceptions of national character are unfounded stereotypes. An appreciation of that fact by the public might improve international relations, so research is needed to understand the origins and persistence of national-character stereotypes. Psychologists have begun to explore the utility of aggregate personality profiles, which reflect subtle but real differences between cultures in mean levels of personality traits.

The intervening role of social worldviews in the relationship between the five‐factor model of personality and social attitudes

The present research investigates in a student (N = 183) and a voter sample (N = 276) whether the relationships between the Five‐Factor Model (FFM) personality dimensions and social attitudes (i.e. Right‐Wing Authoritarianism [RWA] and Social Dominance Orientation [SDO]) are mediated by social worldviews (i.e. dangerous and jungle worldviews). Two important results were obtained. First, the perception of the world as inherently dangerous and chaotic partially mediated the relationships of the personality dimensions Openness and Neuroticism and the social attitude RWA. Second, the jungle worldview completely mediated the relationships between Agreeableness and SDO, but considerable item overlap between the jungle worldview and SDO was also noted. It was further revealed that acquiescence response set and item overlap had an impact on social worldviews and attitudes, but that their relationships were hardly affected by these biases. The discussion focuses on the status of social worldviews to explain social attitudes. Copyright © 2006 John Wiley & Sons, Ltd.     

类别不确定下的特征推理是基于类别还是基于特征联结

共有3个实验探讨归类不确定情况下的特征推理是基于类别进行还是基于特征联结进行。实验1在中文条件下重复了Verde等人2005的实验,得出了与之相符的结果,这个结果用基于类别的理性模型的设想或者是用基于特征联结的设想都可以解释。实验2考察被试在靶类别的类别特征频次并且特征结合出现频次高低不同的条件下特征推理的情况,实验2的结果表明,高集中与低集中两种条件下特征推理没有显著差异,不符合特征推理是基于类别进行的设想,而与特征推理是基于特征联结进行的设想吻合。实验3进一步考察被试在特征结合出现的总频次并且靶类别中特征结合出现的总频次高低不同的条件下特征推理的情况,结果表明,在高结合条件下进行特征推理要优于在低结合条件,支持了在归类不确定情况下的特征推理是基于特征联结进行的设想。据此可以认为,人们的特征推理是基于特征之间联结的频次进行,而不是基于类别进行
