Underlying Spatial Skills to Support Navigation Through Large,Unconstrained Environments

Studies of spatial navigation in real‐world settings have been limited to neighborhoods, campuses, and buildings. These locations have structural components, such as roads or hallways, which may direct navigation. The current study assessed navigational skills within a large‐scale forested environment that contained few pre‐established paths. Participants were asked to find flags using only a map and compass; dependent variables included target‐finding accuracy and efficiency. In addition, measurements of sense of direction, strategy, and working memory were taken to identify how these cognitive abilities influence performance. The results demonstrate the expected correlations between sense of direction and navigational success. An unexpected correlation between spatial working memory and navigational success was also found, which was the only significant predictor of performance when all measures were regressed together. These results suggest that studies should not forget basic cognitive abilities, which may predict success more than measures of sense of direction. Copyright © 2015 John Wiley & Sons, Ltd.     

Is Religious Coping Associated with Cumulative Health Risk? An Examination of Religious Coping Styles and Health Behavior Patterns in Alzheimer’s Dementia Caregivers

The current study explored the relationship between religious coping and cumulative health risk associated with health behavior patterns in a sample of 256 Latina and Caucasian female caregivers of elderly relatives with dementia. Primary analyses examined the relationship between religious coping (both positive and negative) and an overall index of cumulative health risk. Secondary analyses were conducted on the individual health behaviors subsumed in the broader index. Findings revealed that negative religious coping was significantly associated with increased cumulative health risk. Positive religious coping was predictive of decreased cumulative health risk among Latina caregivers but not among Caucasians. Negative religious coping was significantly associated with both an increased likelihood for weight gain and increased dietary restriction. Positive religious coping was associated with decreased likelihood for weight gain in Latinas. Implications for both caregivers and clinicians are discussed.     

Evaluating Attitudes and Experience With Emerging Technology in Cadets and Civilian Undergraduates

Existing research on the characteristics of digital natives, traditionally defined as those born after 1980, has shown subtle differences in how they approach technology compared with other cohorts. However, much of the existing research has focused on a limited set of conventional technologies, mostly related to learning. In addition, prior research has shown differences within this cohort in how they respond to autonomous technology (e.g., trust, reliance; Pak, Rovira, McLaughlin, &; Baldwin, 2016 Pak, R., Rovira, E., McLaughlin, A., &; Baldwin, N. (2016). Does the domain of technology impact user trust? Investigating trust in automation across different consumer-oriented domains in young adults, military, and older adults. Theoretical Issues in Ergonomics Science, 18, 199–220. 10.1080/1463922x.2016.1175523[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). The purpose of this short report, representing the first wave of data collection in a larger study examining technology experience and attitude change, is to directly address 2 shortcomings in the literature on digital natives which tends to emphasize: (a) civilian students; and (b) conventional, often learning technologies. We addressed these 2 issues by recruiting 2 subgroups of digital natives (students and military cadets) and assessing attitudes and experience with a wide range of technology spanning from conventional (e.g., mobile) to emerging (e.g., robotics). The results showed that that both groups were surprisingly unfamiliar with emerging consumer technologies. Additionally, contrary to expectations, cadets were significantly, albeit only slightly, less experienced with mobile technologies, VR/augmented reality, social media, and entertainment technology as compared to civilian undergraduates.     

Determinants of religious expression in the workplace

With the importance of religion to many individuals and the legal protections present in various countries, religious expression in the workplace is a phenomenon worthy of greater research and understanding. This study examined several potential antecedents of religious expression in the workplace. Results from a sample of employed individuals suggest that both individual and organisational factors, including individual religiosity, company culture and value congruence, influence the level of workplace religious expression.     

The Meaning of Obesity in the Church: A Pastoral Leader’s Perspective

The purpose of this study is to highlight a unique case regarding obesity and weight loss in the Christian church that emerged when interviewing men who had experienced bariatric surgery. Thirty-four-year-old “Pastor Tom” was removed from his position in the church due to his obesity. Through critical reflection, utilizing an intrinsic case study methodology, the authors explore how this research participant constructed meaning around obesity and weight loss. In this study, two major themes emerged: (1) leading by example and (2) becoming a leader. The study includes a discussion of implications for the church as well as teaching, clinical, and research implications.     

Perfectionism in African American students: relationship to racial identity, GPA, self-esteem, and depression

This study examined 219 African American college students at predominantly White universities using the constructs of perfectionism, academic achievement, self-esteem, depression, and racial identity. Cluster analysis was performed using the Almost Perfect Scale-Revised (APS-R), which yielded three clusters that represented adaptive perfectionists, maladaptive perfectionists, and nonperfectionists. These three groups were compared on their scores on the Rosenberg Self-Esteem Scale (RSES), the Center for Epidemiological Studies-Depression Scale (CES-D), the Cross Racial Identity Scale (CRIS), and Grade Point Average (GPA). Adaptive perfectionists reported higher self-esteem and lower depression scores than both the nonperfectionists and maladaptive perfectionists. Adaptive perfectionists had higher GPAs than nonperfectionists. On the racial identity scales, maladaptive perfectionists had higher scores on Pre-Encounter Self Hatred and Immersion-Emersion Anti-White subscales than adaptive perfectionists. The cultural and counseling implications of this study are discussed and integrated. Finally, recommendations are made for future studies of African American college students and perfectionism.     

Effects of D-amphetamine and ethanol on variable and repetitive key-peck sequences in pigeons

This experiment assessed the effects of d-amphetamine and ethanol on reinforced variable and repetitive key-peck sequences in pigeons. Pigeons responded on two keys under a multiple schedule of Repeat and Vary components. In the Repeat component, completion of a target sequence of right, right, left, left resulted in food. In the Vary component, 4-peck sequences differing from the previous 10 produced food. d-Amphetamine (0.1-3.0 mg/kg, i.m.) was administered in two separate phases, separated by ethanol administration (1.0-2.0 g/kg, i.g.). Under control conditions, measures of variability were high in the Vary component, and lower in the Repeat component. Following administration of the highest dose of d-amphetamine, but not ethanol, response rates decreased in both components. d-Amphetamine and ethanol tended to increase overall sequence variability in the Repeat component, and had less of an effect in the Vary component. Performance in the Repeat component during Phase 2 of d-amphetamine administration was more disrupted than during Phase 1. Measures of variability and repetition based on shifts in the relative frequency distributions of the 16 possible keypeck sequences differed from those based on the overall measure of variability, highlighting the importance of considering both molar and molecular measures when assessing the effects of drugs on reinforced variability and repetition. In addition, the shifts in the relative frequency distribution of response sequences suggest that d-amphetamine produced decrements in repeat performance by decreasing discriminative control within response sequences, whereas ethanol decreased repeat performance by decreasing discriminability between components as well as discriminative control within response sequences.     

Affective responses to abuse in the workplace: The role of hope and affective commitment

Affective responses constitute the mechanism by which abusive supervision received is associated with subordinates’ turnover intentions. Using affective events theory (AET) as a theoretical framework, we suggest that abusive supervision is a contextual event that is associated with subordinates’ affective reactions and corresponding evaluative judgment of their workplace, which ultimately leads to increased turnover intentions, a prominent withdrawal outcome. We examine two affective responses as mediators, hope (a goal-related affective state based on the expectation of positive outcomes) and affective commitment (affect-based evaluation of the organization). Two samples from a field study (n = 209) and an experiment (n = 427) were analyzed using structural equation modeling. Results supported our proposed chain of relationships, suggesting that subordinates are likely to experience decreased hope and affective commitment after having experienced abuse from a supervisor, which subsequently impact their withdrawal intention to leave the organization.     

The influence of egocentrism and focalism on people's optimism in competitions: when what affects us equally affects me more

Six experiments investigated people's optimism in competitions. The studies involved hypothetical and real competitions (course grades in Experiments 1 and 2, a trivia game in Experiments 3-5, and a poker game in Experiment 6) in which the presence of shared adversities and benefits (factors that would generally hinder or help the absolute performance of all competitors) was manipulated. Shared adversities tended to reduce people's subjective likelihoods of winning, whereas shared benefits tended to increase them. The findings suggest that when people judge their likelihood of winning, their assessments of their own strengths and weaknesses have greater impact than their assessments of their competitors' strengths and weaknesses. We identify egocentrism and focalism as two causes of the bias. The experiments revealed moderators of this bias, but also illustrated its robust nature across a variety of conditions.
