Construct Validity of the Need to Belong Scale: Mapping the Nomological Network

Nine studies examined the construct validity of the Need to Belong Scale. The desire for acceptance and belonging correlated with, but was distinct from, variables that involve a desire for social contact, such as extraversion and affiliation motivation. Furthermore, need to belong scores were not related to insecure attachment or unfulfilled needs for acceptance. Need to belong was positively correlated with extraversion, agreeableness, and neuroticism and with having an identity that is defined in terms of social attributes. Need to belong was associated with emotional reactions to rejection, values involving interpersonal relationships, and subclinical manifestations of certain personality disorders.     

False Memories in Individuals at Risk for Developing an Eating Disorder

In the present study, the authors used the Roediger and McDermott paradigm (H. L. Roediger & K. B. McDermott, 1995) to examine the creation of false memories in individuals at risk for developing an eating disorder. Thirty-three controls and 34 individuals at risk for eating disorders studied 6 word lists taken from the paradigm. Three lists were food related (bread, fruit, sweet), and 3 were not food related (king, doctor, black). Both groups produced false memories (i.e., recalled or recollected words that were not presented in the lists), and controls actually produced more false memories than the at-risk individuals produced in the recall of the food-related items. Groups did not differ in their recall of items not related to food.     

The factor structure and composite reliability of the Rosenberg Self-Esteem Scale among ex-prisoners

The aim of this study was to examine the factor structure and composite reliability of the Rosenberg Self-Esteem Scale (RSES) using a sample of 669 ex-prisoners identified in the National Survey of American Life. Six distinct factor models, with uncorrelated measurement error terms, were specified and tested using confirmatory factor analysis (CFA). Results indicated that the two-factor model consisting of positive and negative latent variables provided a better fit to the data than the alternative models. Moreover, only positive self-esteem was a significant predictor of recidivism. Composite reliability indicated that the two factors were measured with very good reliability. The results consequently provide additional support for a two-dimensional model of the RSES within offender populations.     

Two for the Price of One: Assessment Center Training to Focus on Behaviors Can Transfer to Performance Appraisals

The purpose of this study was to evaluate whether the training and experience of assessors to record behaviors as part of an actual organizational assessment center (AC) would transfer to another context: performance appraisals. Specifically, we examined the effects of transfer of training on managers' behavioral specificity in comments on performance evaluations. Performance appraisal comments from managers who had received training and participated as an assessor and from managers who had not were compared. Analyses revealed significant differences between managers who were trained as assessors compared with managers who were not, suggesting transfer of training effects. Results provide the first empirical evidence for an added benefit of AC assessor participation and training.     

The Mediating Effects of Adaptive Skill on Values-Performance Relationships

Researchers posit that adaptability is an important contributor of performance and that it mediates the effects of distal predictors on performance. As limited empirical evidence supports these relationships, the present research examined whether adaptive skill mediated the effects of values on performance for military leaders. We found that adaptive skill was a distinct construct which uniquely contributed to overall performance. Further, we found that adaptive skill fully mediated the effects of values on technical-administrative behaviors and partially mediated the effects of values on contextual performance and leader behaviors. We discuss the need to further test the nomological network of KSAO–adaptability–performance relationships.     

Associations between cortical thickness and general intelligence in children,adolescents and young adults

Neuroimaging research indicates that human intellectual ability is related to brain structure including the thickness of the cerebral cortex. Most studies indicate that general intelligence is positively associated with cortical thickness in areas of association cortex distributed throughout both brain hemispheres. In this study, we performed a cortical thickness mapping analysis on data from 182 healthy typically developing males and females ages 9 to 24 years to identify correlates of general intelligence (g) scores. To determine if these correlates also mediate associations of specific cognitive abilities with cortical thickness, we regressed specific cognitive test scores on g scores and analyzed the residuals with respect to cortical thickness. The effect of age on the association between cortical thickness and intelligence was examined. We found a widely distributed pattern of positive associations between cortical thickness and g scores, as derived from the first unrotated principal factor of a factor analysis of Wechsler Abbreviated Scale of Intelligence (WASI) subtest scores. After WASI specific cognitive subtest scores were regressed on g factor scores, the residual score variances did not correlate significantly with cortical thickness in the full sample with age covaried. When participants were grouped at the age median, significant positive associations of cortical thickness were obtained in the older group for g-residualized scores on Block Design (a measure of visual-motor integrative processing) while significant negative associations of cortical thickness were observed in the younger group for g-residualized Vocabulary scores. These results regarding correlates of general intelligence are concordant with the existing literature, while the findings from younger versus older subgroups have implications for future research on brain structural correlates of specific cognitive abilities, as well as the cognitive domain specificity of behavioral performance correlates of normative gray matter thinning during adolescence.     

An Eastern Orthodox Theological Basis for Interplanetary Environmental Ethics

As a result of our technological advances in space exploration, human enterprise is no longer limited to the confines of planet Earth. Although several philosophical approaches to environmental ethics have already been advocated for human encounters with other planets such as Mars, it may be argued that various religious worldviews will significantly influence these suggested value systems. In this article, we present an Eastern Orthodox Christian interpretation of Creation and explore the theological meaning of the human vocation as Priests of Creation. An appropriate application of these two principles provides a theological basis for an interplanetary eco-praxis.     

Disgust sensitivity and fear of animals: Effect of exposure to violent or revulsive material

Subjects were asked to rate their fear of four categories of animals both before and after viewing one of three brief video films. Subjects watched either (a) a video depicting extreme violence, (b) a video depicting revulsive scenes from a hospital operation, or (c) a video showing neutral landscape scenes. The results suggested that exposure to violent material produced an increase in fear ratings for animals in the Hi Fear/Hi Predatory category (e.g., lion, tiger, shark) which was significantly different from a decrease in fear ratings recorded for all other categories of animals. However, exposure to revulsive material produced an increase in fear ratings to animals in both the Hi Fear/Lo Predatory category (e.g., rat, spider, snake) and the Hi Revulsion category (e.g., slug, maggot, snail) which was significantly different to the decrease in fear ratings recorded for animals in the remaining categories. The neutral landscape scenes produced a decrease in mean fear ratings for all categories of animals. These results are considered further support for a disease-avoidance model of common animal fears, and suggest a causal link between disgust sensitivity and fear of certain fear-relevant animals.     

Investigating the Role of Emotion in Science Center Visitor Learning

ABSTRACT

A number of investigators have argued that emotion plays an important role in free-choice learning in settings such as museums, science centers, zoos, and aquariums, particularly given the relationship between emotion and cognition. Despite considerable research on the cognitive aspects of visits, empirical studies on emotion in such settings are virtually non-existent. This study investigated the role that emotion plays in facilitating and enhancing learning at a science center. Three major research questions were addressed: (a) Can emotion be measured using Russell's Affect Grid in a non-laboratory setting such as an interactive science center? (b) If so, do different types of science center experiences create measurably different levels of emotional arousal and/or valence in visitors? and (c) If so, was there evidence that elevated arousal and/or valence enhanced or retarded visitors' long-term cognitive science learning? The study provided evidence that emotion could be measured using a modified Affect Grid technique and that a particular traveling exhibition generated arousal levels above baseline levels as determined by a control group. Findings suggest a relationship between emotional arousal and positive changes in visitor long-term cognition, attitudes, and behaviors.     

Perceptual constraints on implicit learning of spatial context

If perspective views of an object in two orientations are displayed in alternation, observers will experience the object rotating back and forth in three-dimensional space. Rotational motion is perceived even though only two views are displayed and each view is two-dimensional. The results of 5 experiments converge on the conclusion that the perception of apparent rotational motion produces representations in visual memory corresponding to the spatial structure of the object along its arc of rotation. These representations are view-dependent, preserving information about spatial structure from particular perspectives, but do not preserve low-level perceptual details of the stimulus.
