This study investigated determinants of success in a 'synthetic work' task designed to reflect the requirement for multitasking that is common to many occupations. Participants were administered tests of working memory capacity (WMC) and processing speed (PS), and they reported experience with videogames, a type of activity presumed to involve multitasking. Results revealed that WMC was a strong predictor of multitasking in a 'non-emergency' condition when the pace of the tasks was relatively slow, whereas PS was a weaker predictor. Additionally, there was evidence for the incremental validity of videogame experience (VGE), consistent with the possibility that multitasking is supported by a general, trainable skill. Finally, individual differences in strategy use accounted for a large proportion of the variance in multitasking, above and beyond other predictor variables, and WMC predicted use of an effective strategy.

The present research moved beyond focusing on negative dispositions to investigate the influence of positive aspects of personality, namely extraversion and openness, on stress responses including appraisals, affect and task performance. Challenge appraisals occur when stressor demands are deemed commensurate with coping resources, whereas threat appraisals occur when demands are believed to outweigh coping resources. We examined the unique influence of personality on stress responses and the mediating role of appraisals. Personality was assessed, and then participants (N = 152) were exposed to a validated math stressor. We found unique effects on stress responses for neuroticism (high threat and negative affect and low positive affect), extraversion (high positive and low negative affect) and openness (high positive and low negative effect and better performance). Mediation analyses revealed that neuroticism indirectly worsened performance, through threat appraisals, and that openness indirectly increased positive affect through lower threat. These findings highlight the importance of investigating multiple aspects of personality on stress responses and provide an avenue through which stress responses can be changed-appraisals. Only by more broad investigations can interventions be tailored appropriately for different individuals to foster stress resilience.

Guided by regulatory focus theory, we examined whether messages tailored to individuals' promotion-or prevention-goal orientation (regulatory focus) elicit positive thoughts and feelings about physical activity and increase participation in physical activity. Inactive participants (N = 206) were assigned randomly to receive either promotion-focused or prevention-focused messages encouraging physical activity. Two weeks after message exposure, we assessed participants' thoughts and feelings about physical activity and physical activity behavior. Tailored messages that fit individuals' regulatory focus led to greater physical activity participation and more positive feelings than non-fit messages, particularly in the promotion-focused condition. Furthermore, positive retrospective feelings about physical activity mediated the effects of the tailored messages on behavior. These findings provide support for regulatory focus theory and direction for enhancing the effectiveness of messages encouraging physical activity and other health behaviors.

Stability and routine are two words that can rarely be used to describe the present-day workplace. Instead, individuals, teams, and organizations are required to respond to dynamic and changing situations. As a result, researchers have become increasingly interested in understanding performance adaptation, evident in the substantial growth in research over the past two decades. However, what researchers mean when they study adaptation is often broad, vague, and inconsistent—especially at the organizational level—such that drawing solid conclusions is challenging. To move toward integration, we focused the review on individual and team performance adaptation, where the mechanisms of adaptation can be observed. We developed a conceptual taxonomy to map extant research, provide insights for synthesis, and identify directions for future theory building and research. Specifically, we identify four theoretical approaches: (a) a performance construct, (b) an individual difference construct, (c) a change in performance, and (d) a process. Each perspective is reviewed, identifying definitions and key assumptions; discussing conceptual foundations and empirical findings; and highlighting discrepancies, similarities, and opportunities for synthesis. The discussion recommends useful lines of inquiry for future research. Moreover, to promote individual-, team-, and organizational-level integration, we propose a multilevel conceptual architecture specifying the what (nature), where (levels), and how (mechanisms) of adaptation to better define the nature of the phenomenon. In combination, the taxonomy, review content, and conceptual architecture are designed to enhance conceptual clarity and consistency, encourage integration, and advance theory and research on adaptation as a pervasive phenomenon in organizational science.

This study tested several relationships predicted by the Health Action Process Approach (HAPA) in a sample of 175 generally healthy, inactive, middle-aged women (40–65 yrs old) over a 12 week period. Participants’ physical activity, risk perceptions, outcome expectancies, action self-efficacy, and intentions were measured at baseline. Planning and maintenance self-efficacy were measured four weeks later. Physical activity behaviour was measured twelve weeks after baseline. The HAPA relationships were examined using a structural equation model. The data fit the model well and revealed several significant relationships. Action self-efficacy was the best predictor of intention. Maintenance self-efficacy was the best predictor of planning and behaviour. Contrary to the tenets of HAPA and to past research, planning did not predict behaviour. Overall, HAPA provides a useful framework for identifying determinants of physical activity intentions and behaviour within a group of inactive, middle-aged women.

Using gain-framed messages exclusively may be a means of increasing the efficacy of physical activity materials.

Sources of individual differences in scientific problem solving were investigated. Participants representing a wide range of experience in geology completed tests of visuospatial ability and geological knowledge, and performed a geological bedrock mapping task, in which they attempted to infer the geological structure of an area in the Tobacco Root Mountains of Montana. A Visuospatial Ability × Geological Knowledge interaction was found, such that visuospatial ability positively predicted mapping performance at low, but not high, levels of geological knowledge. This finding suggests that high levels of domain knowledge may sometimes enable circumvention of performance limitations associated with cognitive abilities.

Computer-based team training positively impacts teamwork and patient care during simulated patient resuscitations. This low-resource team training intervention may help to address the dissemination and sustainability issues associated with larger, more costly team training programs.
