The other side of we: when outgroup members express common identity

Previous research on the common ingroup identity model has focused on how one's representations of members of the ingroup and outgroup influence intergroup attitudes. Two studies reported here investigated how learning how others, ingroup or outgroup members, conceive of the groups within a superordinate category affects intergroup bias and willingness to engage in intergroup contact. Across both studies, high school students who learned that other ingroup members categorized students at both schools within the common identity of "students" showed less intergroup bias in evaluations and greater willingness for contact. However, consistent with the hypothesized effects of identity threat, when participants read that outgroup members saw the groups within the superordinate category, they exhibited a relatively negative orientation, except when ingroup members also endorsed a superordinate identity (Study 1). This result occurred even when the relative status of the groups was manipulated (Study 2).     

Clinical validation of the trait and state versions of the Food Craving Questionnaire

This is the first study to evaluate the psychometric properties of the Food Craving Questionnaire-Trait (FCQ-T), and Food Craving Questionnaire-State (FCQ-S) measures using a clinically heterogeneous sample of eating disorder patients (N = 177) recruited from seven different outpatient eating disorder treatment centers in Spain. Confirmatory factor analyses (CFAs) corroborated the factor structures of the FCQ-T and FCQ-S. The measures' scores and their factor-derived scale-scores yielded internal consistency reliability indexes that ranged from adequate to excellent. The measures were predictive of eating disorder symptoms. As expected, the FCQ-T was more strongly associated with eating disorder psychopathology than the FCQ-S. The results replicated the psychometric properties of the FCQ-T and FCQ-S in eating disorder populations and could become useful tools in clinical and research settings.     

Vicarious intergroup contact and the role of authorities in prejudice reduction

The present study focuses on the effect of vicarious intergroup contact and the support of an authority figure on the improvement of outgroup and meta-stereotype evaluations. Meta-stereotype refers to the shared beliefs of ingroup members about how they consider outgroup members to perceive their group. Three preliminary studies were carried out to determine desirable and undesirable characteristics for a good basketball performance, the task that best demonstrates the application of these characteristics, and the two groups (basketball teams) that should be involved in the vicarious intergroup contact. Fans of one of the basketball teams participated in the current study. Vicarious intergroup contact improved outgroup and meta-stereotype evaluations as compared with a no contact condition. In addition, the positive effects of vicarious intergroup contact significantly increased when it was supported by an authority figure. More importantly, our study also shows that the improvement of outgroup evaluation was partially mediated by changes on meta-stereotypes.     

"Did you have a nice evening?" A day-level study on recovery experiences, sleep, and affect

In this study, the authors used a within-person design to examine the relation between recovery experiences (psychological detachment, relaxation, mastery experiences) during leisure time, sleep, and affect in the next morning. Daily survey data gathered over the course of 1 work week from 166 public administration employees analyzed with a hierarchical linear modeling approach showed that low psychological detachment from work during the evening predicted negative activation and fatigue, whereas mastery experiences during the evening predicted positive activation and relaxation predicted serenity. Sleep quality showed relations with all affective states variables. This study adds to research on job-stress recovery and affect regulation by showing which specific experiences from the nonwork domain may improve affect before the start of the next working day.     

Managing discrimination in selection: the influence of directives from an authority and social dominance orientation

The authors examined one manner in which to decrease the negative impact of social dominance orientation (SDO), an individual difference variable that indicates support for the "domination of 'inferior' groups by 'superior' groups" (J. Sidanius & F. Pratto, 1999, p. 48), on the selection of candidates from low-status groups within society. Consistent with the tenets of social dominance theory, in 2 studies we found that those high in SDO reported that they were less likely to select a potential team member who is a member of a low-status group (i.e., a White female in Study 1 and a Black male in Study 2) than those low in SDO. However, explicit directives from an authority moderated this effect such that those high in SDO were more likely to select both candidates when authority figures clearly communicated that job performance indicators should be used when choosing team members. Thus, our studies suggest that the negative effects of SDO may be attenuated if those high in SDO are instructed by superiors to use legitimate performance criteria to evaluate job candidates.     

Police officers' credibility judgments: Accuracy and estimated ability

A study was conducted to examine Spanish police officers' and nonofficers' lie‐ and truth‐detection accuracy, as well as their estimated detection ability. The participants were 121 police officers and 146 undergraduates who watched videotaped truthful and deceptive statements. They had to indicate: (1) whether each statement was truthful or deceptive, and (2) how good police officers were, in comparison with the general population, at detecting the truthfulness or deceptiveness of a statement. Results indicate that police officers' accuracy was not higher than that of nonofficers, rather, while the officers reached an accuracy rate close to chance probability, the undergraduates surpassed that probability. Officers had a very strong tendency to judge the statements as deceptive; this made them less accurate than the students in judging the truthful accounts, while both groups reached a similar accuracy when judging the deceptive ones. Both occupational samples considered that the police are more capable of identifying truths and lies than the general population. However, this belief was stronger among the officers themselves than among the nonofficers. No significant correlation between estimated ability and accuracy was found for either sample. The results are explained in terms of the participants' wrong beliefs about the cues to deceit and the socialization process that police officers undergo, which would increase their confidence and perceived ability while hindering their learning of the actual indicators of deceit. The need for officers to receive training is emphasized, and some directions are given on how this training should be carried out.     

Open Problems in the Philosophy of Information

Abstract: The philosophy of information (PI) is a new area of research with its own field of investigation and methodology. This article, based on the Herbert A. Simon Lecture of Computing and Philosophy I gave at Carnegie Mellon University in 2001, analyses the eighteen principal open problems in PI. Section 1 introduces the analysis by outlining Herbert Simon's approach to PI. Section 2 discusses some methodological considerations about what counts as a good philosophical problem. The discussion centers on Hilbert's famous analysis of the central problems in mathematics. The rest of the article is devoted to the eighteen problems. These are organized into five sections: problems in the analysis of the concept of information, in semantics, in the study of intelligence, in the relation between information and nature, and in the investigation of values.

The Psychometric Properties of the Orthogonal Cultural Identification Scale in Asian Americans

Reliability (internal consistency and test‐retest) and validity (construct and factorial) of the Orthogonal Cultural Identification Scale (OCIS; E. R. Oetting & F. Beauvais, 1990–1991) were evaluated in a sample of Asian American university students. Ethnic identification, measured using the OCIS, and acculturation, measured using the Suinn‐Lew Asian Self‐Identity Acculturation Scale (R. M. Suinn, K. Rickard‐Fugueroa, S. Lew, & P. Vigil, 1987), are hypothesized to measure related but separate constructs. Análisis de fiabilidad (consistencia interna y estabilidad temporal), y de validez (conceptual y factorial) de la Escala Ortagonal de Identificación Cultural (OCIS; E. R. Oetting & F. Beauvais, 1990–1991) fueron evaluados en un grupo de estudiantes universitarios Asiáticos Americanos. La identificación étnica fue medida usando la OCIS, y la aculturación fue medida usando la Escala de Identidad de Ser y Aculturación Asiática de Suinn‐Lew (R. M. Suinn, K. Rickard‐Figueroa, S. Lew, & P. Vigil, 1987). Se presenta la hipótesis que la identificación étnica y la aculturación miden conceptos separados que estan relacionados.
