Reuse and Recycle: The Development of Adaptive Expertise,Routine Expertise,and Novelty in a Large Research Team

Combining innovation and efficiency is ideal in many organizational settings. Adaptive expertise represents a cognitive explanation of how individuals and teams can learn to achieve simultaneous innovation and efficiency. In 2004, scientists led twin rovers on Mars in the search for historical water. The science team experienced a remarkable increase in efficiency, adapting with flexibility to unexpected events and dynamic, dwindling resources. After discussing the conceptual differences between adaptive expertise and related team learning and innovation concepts, we examine longitudinal behavioral data on novelty, routine and adaptive expertise. Sequential time series ARIMA analyses reveal that novelty fluctuated randomly, but both routine and adaptive expertise significantly increased over time. In addition, novelty, routine expertise, and adaptive expertise did not significantly predict each other directly or at a lag, suggesting that these are indeed three distinct constructs. Implications for theory and research on efficiency and innovation are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Authentic leadership and its relationships with work engagement and organizational citizenship behaviors in military units: The role of identification as a mediating variable

The objective of the study is to explore the relationship of authentic leadership with work engagement and organizational citizenship behaviors (OCB) in military units, measuring the mediating effect of personal identification with the leader and social identification with the military unit. We used the Structural Equation Modeling (SEM) technique to analyze data from a sample of 225 Spanish military troops. The results showed that social identification with the military unit influenced the relationship of authentic leadership with the outcome variables.     

Rehabilitating civilian victims of war through psychosocial intervention in Sierra Leone

This research assessed an intervention (involving drug therapy and psychoeducational counseling) for war trauma in Sierra Leone. We examine the impact of the intervention on symptoms of post‐traumatic stress disorder (PTSD) and indicators of intergroup emotions and attitudes. Civilian war victims were drawn from a rehabilitation program (Intervention, N=50) or a waiting list Control group (N=50). The rehabilitation program combined general psychiatric treatment with additional life skills support. Those in the Intervention group had significantly lower PTSD symptoms and also scored lower on Intergroup Anxiety and Outgroup Blame, than those in Control. The intervention had an indirect effect on PTSD symptoms through Intergroup Anxiety. The reduction in PTSD in the intervention was greater for participants with a stronger identification with Sierra Leone.     

Revision: is visual perception a requisite for visual imagery?

Vision is the most highly developed sense in man and represents the doorway through which most of our knowledge of the external world arises. Visual imagery can be defined as the representation of perceptual information in the absence of visual input. Visual imagery has been shown to complement vision in this acquisition of knowledge--it is used in memory retrieval, problem solving, and the recognition of properties of objects. The processes underlying visual imagery have been assimilated to those of the visual system and are believed to share a neural substrate. However, results from studies in congenitally and cortically blind subjects have opposed this hypothesis. Here I review the currently available evidence.     

Behavioral Unit of Selection and the Operant-Respondent Distinction: The role of Neurophysiological Events in Controlling the Verbal Behavior of Theorizing about Behavior

A Controlled Study of Suicide in Middle‐Aged and Older People: Personality Traits,Age, and Psychiatric Disorders

Personality traits were examined using the NEO Five‐Factor Inventory–Revised in an Australian psychological autopsy study involving 259 suicide deaths and 181 sudden death controls aged 35 years and over. Interviews included the Structured Clinical Interview for DSM‐IV to determine the presence of psychiatric disorder. Personality traits of suicide deaths differed significantly from those of controls, scoring higher in the Neuroticism and Openness to Experience domains and lower on the Agreeableness and Extraversion domains. These findings varied with the presence of psychiatric disorder and by age. High Neuroticism scores were the most consistent finding in people who died by suicide, although these scores decreased in older suicides.
