The intersection of individual differences,personality variation, & military service: A twin comparison design

ABSTRACT

In societies where military service is voluntary multiple factors are likely to affect the decision to enlist. Past research has produced evidence that a handful of personality and social factors seem to predict service in the military. However, recent quantitative genetic research has illustrated that enlistment in the military appears to be partially heritable and thus past research is potentially subject to genetic confounding. To assess the extent to which genetic confounding exists, the current study examined a wide range of individual-level factors using a subsample of twins (n = 1,232) from the restricted-use version of the National Longitudinal Study of Adolescent to Adult Health. The results of a series of longitudinal twin comparison models, which control for the latent sources of influence that cluster within families (i.e., shared genetic and family factors), illustrated generally null findings. However, individuals with higher scores on measures of extraversion and the general factor of personality were more likely to enlist in the military, after correction for familial confounding. Nonetheless, the overall results suggest that familial confounding should be a methodological concern in this area of research, and future work is encouraged to employ genetically informed methodologies in assessments of predictors of military enlistment.     

Ethical leadership,person-organizational fit,and productive energy: a South African sectoral comparative study

ABSTRACT

Research suggests that ethical leadership (EL) affects employee behavior and organizational functioning. This study aimed to determine the relationship between EL and productive energy (PE), as mediated by person-organizational fit (POF). The study used assumptions of the social learning and social exchange theories that posit that leadership has a direct impact on employee behavior, mainly through role modeling and the reciprocal nature thereof. An empirical paradigm using a cross sectional quantitative design was used. The PE instrument (developed in the USA) was assessed for construct validity within the South African context (exploratory and confirmatory factor analysis). The analysis included a comparison between the private and public sectors, emphasizing the importance of context as differentiator. Relatively high, statistically significant correlations were found between the variables for both sectors and the combined sample. The hierarchical regression analysis indicated that 18% of the variance in PE is explained by EL. This model was improved by the inclusion of POF (total variance of 32% explained). The conceptual model was confirmed with structural equation modeling (SEM). The findings of this study suggest that EL has a significantly positive effect on PE and POF, which mediates the relationship between EL and PE. Sectoral differences were reported.     

Comparing theories of consciousness: Object position,not probe modality,reliably influences experience and accuracy in object recognition tasks

People often claim seeing images completely despite performing poorly. This highlights an issue with conscious representations. We introduce an experimental manipulation aiming to disentangle two prevalent positions: Rich views posit that people virtually represent the external world with unlimited capacity; Sparse views state that representations are reconstructed from expectations and information. In two experiments using the object recognition task, we tested two probe types: Images, which should aid reconstruction more, and Words, which should aid it less. From a sparse view, one should expect that Images lead to greater accuracy and reported experience. We found no reliable differences in accuracy and reported experience across probe types; however, we observed that the object positions influenced both accuracy and reported experience, which is surprising from a Rich view as it seemingly requires assumptions of different access across the visual field. Both theoretical positions thus currently need further development to explain our results.     

Influence of internal and external factors on early language skills: A cross-linguistic study

Cross-linguistic studies can provide information about general and language specific features of language development, but relatively few such studies are available in literature. The main aim of the present study was to investigate, from a cross-linguistic perspective, the roles of the internal factor of gender and external factors of birth order and parental education level on the development of language in 2-year-old children. We examined 351 children growing up in three European language contexts: Croatian (N = 104), Estonian (N = 141) and Finnish (N = 106). Information on lexical skills and word combination ability was collected using the short form of the MacArthur-Bates Communicative Development Inventories and the influence of background factors on these aspects of language development was investigated. No significant differences were found in lexical skills or word combination ability among the three language groups. These aspects of language development varied significantly with gender, but not with external factors. Our findings suggest that internal factors may influence early language development more than external factors.     

Cross-Sectional Survey on Burnout and Musculoskeletal Disorders in Greek and Cypriot Occupational Therapists

Abstract

Background: Occupational therapy is a physically, psychologically and cognitively demanding job. This study aims to explore the epidemiology of musculoskeletal injuries, mental issues, and burnout in occupational therapy practitioners in Greece and Cyprus.

Method: A survey was conducted, including the Patient Health Questionnaire (PHQ-9), the Oldenburg Burnout Inventory, and the Nordic Musculoskeletal Questionnaire.

Results: Out of 247 respondents, 70% reported severe lower back pain, 9.7% of Greek occupational therapists were in the moderate and high PHQ-9 scale, while disengagement and exhaustion were found 2.026 (±0.54) and 2.592 (±0.533) respectively.

Conclusion: High rates of burnout, correlated with psychological and musculoskeletal disorders were identified in both countries. Work-related stress and musculoskeletal disorders may be more evident in countries hit by recession.     

It’s not just “us” versus “them”: Moving beyond binary perspectives on intergroup processes

ABSTRACT

The social psychology of intergroup relations has emerged largely from studies of how one group of people (e.g., whites) think and feel about another (e.g., blacks). By reducing the social world to binary categories, this approach has provided an effective and efficient methodological framework. However, it has also obscured important features of social relations in historically divided societies. This paper highlights the importance of investigating intergroup relationships involving more than two groups and of exploring not only their psychological but also their political significance. Exemplifying this argument, we discuss the conditions under which members of disadvantaged groups either dissolve into internecine competition or unite to challenge the status quo, highlighting the role of complex forms of social comparison, identification, contact, and third-party support for collective action. Binary conceptualizations of intergroup relations, we conclude, are the product of specific sociohistorical practices rather than a natural starting point for psychological research.     

Trajectories of perceived superiority across the transition to marriage

ABSTRACT

Perceived superiority, the tendency to regard one’s own relationship as better than other people’s relationships, is a key relationship maintenance mechanism. Little is known about whether and how it changes during the transition to marriage, a pivotal moment in most couples’ life cycle. In a longitudinal study following 97 couples for three waves across the transition, men presented stable perceived superiority, whereas women presented a curvilinear change in superiority perceptions, with a substantial increase in perceived superiority between T1 and T2 and a significantly reduced change between T2 and T3. In addition, trajectories differed according to partners’ commitment level. More committed and less committed partners both showed a curvilinear change in perceived superiority, though following different patterns. Results point to the functional value of perceived superiority, which emerges as a strategy aimed at sustaining partners through the challenges deriving from the transition to marriage.     

Kierkegaard on Imitation and Ethics: Toward a Secular Project?

This essay demonstrates the prominence of imitation in Kierkegaard’s ethics. I move beyond his idea of authentic existence modeled on Christ and explore the secular dimension of Kierkegaard’s insights about human nature and imitation. I start with presenting imitation as key to understanding the ethical dimension of the relationship between the universal and individual aspects of the human self in Kierkegaard. I then show that Kierkegaard’s moral concepts of “primitivity” and “comparison” are a response to his sociological and psychological observations about imitation from an ethical point of view. In the final section of this paper, I briefly engage Friedrich Schleiermacher’s “ethics of individuality” and Gabriel Tarde’s “laws of imitation” to explore Kierkegaard’s consideration of ethics and imitation as situated within the context of a broader conversation on imitation.
