"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.     

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.     

A System for Relational Reasoning in Human Prefrontal Cortex

The integration of multiple relations between mental representations is critical for higher level cognition. For both deductive- and inductive-reasoning tasks, patients with prefrontal damage exhibited a selective and catastrophic deficit in the integration of relations, whereas patients with anterior temporal lobe damage, matched for overall IQ but with intact prefrontal cortex, exhibited normal relational integration. In contrast, prefrontal patients performed more accurately than temporal patients on tests of both episodic memory and semantic knowledge. These double dissociations suggest that integration of relations is a specific source of cognitive complexity for which intact prefrontal cortex is essential. The integration of relations may be the fundamental common factor linking the diverse abilities that depend on prefrontal function, such as planning, problem solving, and fluid intelligence.     

Signing an Organ Donation Letter: The Prediction of Behavior From Behavioral Intentions1

The signing of an organ donation letter was examined among 149 unmarried university students. The letter was developed for the purpose of conveying one's wishes regarding posthumous donation to one's next of kin. Predictors of letter signing were examined that explain hypothesized inconsistencies between the behavioral intention to sign and actual letter-signing behavior. Respondents were offered the opportunity to sign and send the donation letter to their parents. As predicted, reported willingness to sign the letter was only moderately related to actual behavior. Decision confidence, organ donation knowledge, and perceived decision importance positively influenced signing, independent of willingness. Unfavorability toward defending one's donation decision to one's parents inhibited signing, even among those expressing a high initial willingness to sign.     

Effects of the Acquisition of Prerequisite Behavior on the Learning of Nonvocal Verbal Behavior and Vocal Imitation in Children With Severe Retardation

The effects of acquisition and maintenance of prerequisite interactions, such as attending behavior, nonverbal imitative behavior, and disruptive behavior, on the learning of nonvocal verbal behavior and vocal imitation were evaluated. Four severely retarded children were selected on the basis of low level or absence of the target behaviors (nonvocal verbal behavior and vocal imitation) and failure to reach the acquisition criterion on prerequisite behavior. The results were evaluated visually and by time series analysis. Findings indicated that the acquisition of prerequisite interactions led to superior performance and fewer trials to reach criteria in this language intervention.

     

The perceived impact of tax and regulatory changes

People believe that shared events, events that impact everyone to the same degree, will nonetheless impact them more than others. Across four studies we examined whether this impacts people's reactions to proposed changes to tax and regulatory policies. We found that participants thought that tax (Study 1a and 1b) and regulatory (Study 2) changes would have more of an impact on their own lives than on the lives of people in their same financial situation. We then examined whether these findings are the product of a broad focalism bias or its narrower relative, egocentrism. Because we observed the bias both when participants were asked about their own financial situation or that of someone else, the former appears to be the better explanation (Study 3). We discuss the implications of this bias for people's willingness to embrace policy proposals designed to advance the common good.     

Neurobiological and endocrine correlates of individual differences in spatial learning ability

The polysialylated neural cell adhesion molecule (PSA-NCAM) has been implicated in activity-dependent synaptic remodeling and memory formation. Here, we questioned whether training-induced modulation of PSA-NCAM expression might be related to individual differences in spatial learning abilities. At 12 h posttraining, immunohistochemical analyses revealed a learning-induced up-regulation of PSA-NCAM in the hippocampal dentate gyrus that was related to the spatial learning abilities displayed by rats during training. Specifically, a positive correlation was found between latency to find the platform and subsequent activated PSA levels, indicating that greater induction of polysialylation was observed in rats with the slower acquisition curve. At posttraining times when no learning-associated activation of PSA was observed, no such correlation was found. Further experiments revealed that performance in the massed water maze training is related to a pattern of spatial learning and memory abilities, and to learning-related glucocorticoid responsiveness. Taken together, our findings suggest that the learning-related neural circuits of fast learners are better suited to solving the water maze task than those of slow learners, the latter relying more on structural reorganization to form memory, rather than the relatively economic mechanism of altering synaptic efficacy that is likely used by the former.
