A group-level model of safety climate: testing the effect of group climate on microaccidents in manufacturing jobs

This article presents and tests a group-level model of safety climate to supplement the available organization-level model. Climate perceptions in this case are related to supervisory safety practices rather than to company policies and procedures. The study included 53 work groups in a single manufacturing company. Safety climate perceptions, measured with a newly developed scale, revealed both within-group homogeneity and between-groups variation. Predictive validity was measured with a new outcome measure, microaccidents, that refers to behavior-dependent on-the-job minor injuries requiring medical attention. Climate perceptions significantly predicted microaccident records during the 5-month recording period that followed climate measurement, when the effects of group- and individual-level risk factors were controlled. The study establishes an empirical link between safety climate perceptions and objective injury data.     

Does each hemisphere monitor the ongoing process in the contralateral one?

The present study was conducted to examine hemispheric division of labor in the initial processing and error monitoring in tasks for which hemispheric specialization exists. We used lexical decision as a left hemisphere task and bargraph judgment as a right hemisphere task, and manipulated cognitive load. Participants had to respond to one of two stimuli presented to both visual fields and were instructed to correct their errors. To achieve enough correctable errors, participants were encouraged to respond quickly by using a bonus system. The results showed the classical asymmetry for initial responses in both tasks and reversed asymmetry for corrections in the bargraph task at both load conditions, and in the lexical decision task at the high load condition. The results suggest that each hemisphere monitors the ongoing process in the contralateral one and that the dissociation of initial process and its monitoring grows with load of task.     

Prolonged exposure therapy for chronic combat-related PTSD: a case report of five veterans

Prolonged exposure (PE) therapy has been found efficient in reducing posttraumatic stress disorder (PTSD) symptoms mostly among rape victims, but has not been explored in combat-related PTSD. Five patients with severe chronic PTSD, unresponsive to previous treatment (medication and supportive therapy) are described. Patients were evaluated with the PTSD Symptom Scale-Interview, and Beck Depression Inventory, before and after 10-15 sessions of PE therapy. All five patients showed marked improvement with PE, with a mean decrease of 48% in PTSD Symptom Scale-Interview score and 69% in Beck Depression Inventory score. Moreover, four patients maintained treatment gains or kept improving 6-18 months after the treatment. The results suggest that PE was effective in reducing combat-related chronic PTSD symptoms.

Pitting intuitive and analytical thinking against each other: The case of transitivity

Identifying which thinking mode, intuitive or analytical, yields better decisions has been a major subject of inquiry by decision-making researchers. Yet studies show contradictory results. One possibility is that the ambiguity is due to the variability in experimental conditions across studies. Our hypothesis is that decision quality depends critically on the level of compatibility between the thinking mode employed in the decision and the nature of the decision-making task. In two experiments, we pitted intuition and analytical thinking against each other on tasks that were either mainly intuitive or mainly analytical. Thinking modes, as well as task characteristics, were manipulated in a factorial design, with choice transitivity as the dependent measure. Results showed higher choice consistency (transitivity) when thinking mode and the characteristics of the decision task were compatible.     

Must coping options be severely limited during stressful events: Testing the interaction between primary and secondary appraisals

Abstract

It is assumed that psychological stress develops in personally relevant events when situational demands tax or exceed coping resources (i.e., when coping options are severely limited). Despite the central role of this proposition in defining stress, it has been little investigated due to conceptual overlap in definitions of primary and secondary appraisals. In the present work, the interaction between primary and secondary appraisals was used in order to test this proposition, employing non-overlapping definitions of appraisal components. Appraisals were manipulated independently, using written scenarios of stressful occupational episodes, each with three levels of personal stakes and three levels of coping options. Results indicated that the appraisal factors exerted main, but not interaction, effects on negative and positive moods. This means that emotional response increases in proportion to the level of personal stakes in the encounter, with coping potential acting as independent predictor, rather than moderator variable. Contrary to expectations, therefore, emotional distress might develop under conditions where situational demands fall short of exerting all the available resources for coping. The theoretical implications of these results are discussed.     

A multilevel model of safety climate: cross-level relationships between organization and group-level climates

Organizational climates have been investigated separately at organization and subunit levels. This article tests a multilevel model of safety climate, covering both levels of analysis. Results indicate that organization-level and group-level climates are globally aligned, and the effect of organization climate on safety behavior is fully mediated by group climate level. However, the data also revealed meaningful group-level variation in a single organization, attributable to supervisory discretion in implementing formal procedures associated with competing demands like safety versus productivity. Variables that limit supervisory discretion (i.e., organization climate strength and procedural formalization) reduce both between-groups climate variation and within-group variability (i.e., increased group climate strength), although effect sizes were smaller than those associated with cross-level climate relationships. Implications for climate theory are discussed.     

A small step for rats alters spatial behavior: rats on a bi-level arena explore each level separately

Animal Cognition - We tested rats on a ‘bi-level open-field’ whose two halves were separated vertically by an 8-cm step that the rats could easily ascend/descend. We sought to determine...
