Health and Well-Being in Highly Cohesive Units of the U.S. Army1

A large civilian literature on the role of social support in health and well-being suggests that military units high in unit cohesion should provide their members both significant protection from physical and mental illness and high levels of job satisfaction. This hypothesis was tested with a questionnaire survey of soldiers in Special Forces “A-teams”, generally viewed as the U.S. Army's most cohesive permanent units. As predicted, A-team soldiers reported greater physical and psychological well-being and greater satisfaction with job and career than did soldiers in conventionally organized units, be they Special Forces, airborne, or mechanized infantry. The best predictors in our battery of demographic, personality, and cohesion measures were ratings of social support from and satisfaction with one's Army unit, and relatively more “internal” scores on the Rotter locus-of-control scale. From these data and extensive participant observation we conclude that unit cohesion provides the soldier considerable protection from the stresses of military life, even in peace, and that it is organizational rather than individual variables that are primarily responsible for the very high levels of cohesion and/or social support in Special Forces A-teams.     

Parallel Processing Response Times and Experimental Determination of the Stopping Rule

It was formerly demonstrated that virtually all reasonable exhaustive serial models, and a more constrained set of exhaustive parallel models, cannot predict critical effects associated with self-terminating models. The present investigation greatly generalizes the parallel class of models covered by similar "impossibility" theorems. Specifically, we prove that if an exhaustive parallel model is not super capacity, and if targets are processed at least as fast as non-targets, then it cannot predict such (self-terminating) effects. Such effects are ubiquitous in the experimental literature, offering strong confirmation for self-terminating processing. Copyright 1997 Academic Press. Copyright 1997 Academic Press     

The use of self-efficacy scaling in training student clinicians: Implications for working with stutterers

A scaling technique developed by Bandura for determining an individual's personal performance expectations (self efficacy) was applied to student clinicians working with stutterers. The self-efficacy scores of clinicians conducting treatment increased significantly while the scores of clinicians without treatment experience showed no significant change. As the student clinicians gained clinical experience there appeared to be a corresponding reduction in fear and avoidance of the treatment situation. Clinician fear concerning stuttering treatment appeared to have little relation to performance in treatment as rated by supervisors. The results indicate that self-efficacy scaling may be used to indicate clinician avoidance of working with stuttering clients.     

Listener response to stuttering modification techniques

In two investigations, nonprofessional listeners used a 25-item bi-polar adjective scale to evaluate an adult male speaker who stuttered. In investigation one, 24 listeners evaluated the speaker during a Stuttering Only and a Stuttering + Cancellation condition. In investigation two, 50 listeners evaluated the speaker in a Stuttering Only and a Stuttering + Pullout condition. Listeners in the first investigation did not assign significantly different ratings to the Stuttering Only and Stuttering + Cancellation conditions. In the second investigation listeners rated the Stuttering Only condition more positively than the Stuttering + Pullout condition (p < 0.05). Analysis of listener response to four open-ended questions indicated significantly more positive reaction to the Stuttering Only condition than either of the Stuttering + Modification conditions. Finally, listeners rated the speaker using the cancellation and pullout techniques as being significantly more handicapped than when he was stuttering only. The findings provided preliminary evidence indicating that everyday listeners may react less favorably to an adult male speaker who is modifying his stuttered speech than when this same speaker is simply stuttering.     

Wearable Cameras Are Useful Tools to Investigate and Remediate Autobiographical Memory Impairment: A Systematic PRISMA Review

Autobiographical memory, central in human cognition and every day functioning, enables past experienced events to be remembered. A variety of disorders affecting autobiographical memory are characterized by the difficulty of retrieving specific detailed memories of past personal events. Owing to the impact of autobiographical memory impairment on patients’ daily life, it is necessary to better understand these deficits and develop relevant methods to improve autobiographical memory. The primary objective of the present systematic PRISMA review was to give an overview of the first empirical evidence of the potential of wearable cameras in autobiographical memory investigation in remediating autobiographical memory impairments. The peer-reviewed literature published since 2004 on the usefulness of wearable cameras in research protocols was explored in 3 databases (PUBMED, PsycINFO, and Google Scholar). Twenty-eight published studies that used a protocol involving wearable camera, either to explore wearable camera functioning and impact on daily life, or to investigate autobiographical memory processing or remediate autobiographical memory impairment, were included. This review analyzed the potential of wearable cameras for 1) investigating autobiographical memory processes in healthy volunteers without memory impairment and in clinical populations, and 2) remediating autobiographical memory in patients with various kinds of memory disorder. Mechanisms to account for the efficacy of wearable cameras are also discussed. The review concludes by discussing certain limitations inherent to using cameras, and new research perspectives. Finally, ethical issues raised by this new technology are considered.
