Posttraumatic Stress,Depression, and Insomnia Among U.S. Air Force Pararescuemen

Few studies have examined rates of mental health problems among special duty military personnel, who often have frequent deployments and high exposure to operational stressors and trauma. The current study examined the severity and rates of positive screening for posttraumatic stress, depression, and insomnia among 194 U.S. Air Force pararescuemen (PJs) in the active duty (AD) and National Guard/Reserve (NG/R) components. Overall estimated rates were 11.6% for probable posttraumatic stress disorder (PTSD), 1.6% for probable depression, and 16.1% for clinical insomnia. PJs in the NG/R reported significantly more severe posttraumatic stress symptoms (F(1, 162) = 10.031, p = .002, partial η² = .058) and were approximately twice as likely to screen positive for probable PTSD (8.5% vs. 19.1%; χ²[1] = 3.679, p = .055). No differences in the rate or severity of depression or insomnia symptoms were found. Rates of positive screens are comparable to or lower than previously published rates among military personnel.     

Sad mood reduces inadvertent plagiarism: Effects of affective state on source monitoring in cryptomnesia

In two experiments, we explored the influence of affective state, or mood, on inadvertent plagiarism, a memory failure in which individuals either misattribute the source of an idea to themselves rather than to the true originator or simply do not recall having encountered the idea before and claim it as novel. Using a paradigm in which participants generate word puzzle solutions and later recall these solutions, we created an opportunity for participants to mistakenly claim ownership of items that were, in fact, initially generated by their computer ‘partner.’ Results of both experiments suggest that participants induced into a sad mood before solving the word puzzles made fewer source memory errors than did those induced into a happy mood. Results of Experiment 2 also imply that sad mood reduces some item memory errors. Implications for appraisal theories, such as the affect-as-information hypothesis, are discussed.     

Self-Stigma in Substance Abuse: Development of a New Measure

Little attention has been paid to the examination and measurement of self-stigma in substance misuse. This paper aims to fill this gap by reporting on the development of a new scale to measure self-stigma experienced by people who are misusing substances, the Substance Abuse Self-Stigma Scale. Content validity and item refinement occurred through an iterative process involving a literature search, focus groups, and expert judges. Psychometric properties were examined in a cross-sectional study of individuals (n?=?352) receiving treatment for substance misuse. Factor analyses resulted in a 40-item measure with self devaluation, fear of enacted stigma, stigma avoidance, and values disengagement subscales. The measure showed a strong factor structure and good reliability and validity overall, though the values disengagement subscale showed a mixed pattern. Results are discussed in terms of their implications for studies of stigma impact and intervention.     

The health benefits of writing about positive experiences: The role of broadened cognition

This study tested the potential to elicit a broadened attentional focus through writing about a positive life experience and to derive health benefits from such writing. Participants (n = 38) wrote for 20 min each day for 3 consecutive days about either a positive life experience or a control topic. Writing about positive experiences led to improved physical health (measured 4–6 weeks after writing) compared to control and higher levels of global cognitive focus after writing mediated this effect. Notably, while the positive writing condition was more broadened than control, positive affect was not responsible for this difference. Implications for disclosive writing and the broaden and build model are discussed.     

No templates for rejection: a failure to configure attention to ignore task-irrelevant features

ABSTRACT

Knowing the colour of an upcoming target allows one to bias attention towards objects of that colour. It is far less clear whether knowing the colour of an up-coming distractor can allow one to suppress attention to items of that colour. Arita, Carlisle, and Woodman (2012) suggest that people can create a template for rejection. However, the method used in Arita et al. may have allowed people to adopt a strategy of internally generating a positive cue for the target colour or target hemifield. Here we use a method very similar to theirs, but manipulate the display layouts and the number of un-cued colours in ways that should thwart such strategies. Across three experiments, we find a negative cuing benefit only in a very special circumstance that encourages a strategic shift to internally generating a positive cue (the same circumstance used by Arita et al.). We conclude that people are unable to use a negative feature-cue on a trial-by-trial basis to suppress attention to upcoming distractors, and attribute the finding in Arita et al. to a strategic shift rather than a template for rejection.     

Refining Measurement of Career Indecision Types: A Validity Study

The authors conducted this study to address some of the limitations in previous indecision typology research and to provide validity evidence for the indecision types that were derived. The participants were 566 first‐semester, undecided students enrolled in a career exploration course. Career indecision, personality, and ability measures were used to derive career indecision types through cluster analysis. Four distinct career indecision types were identified. Subsequently, the effect of indecision type on response to a career exploration course was examined. Level of career indecision, the criterion variable, was not differentially affected by indecision type. Implications of the findings for career counseling are discussed.     

A Biodata Inventory Administered via Interactive Voice Response (IVR) Technology: Predictive Validity, Utility, and Subgroup Differences

Although organizations are increasingly using interactive voice response (IVR) systems to help screen and select job applicants, few if any published studies have investigated the effectiveness of such systems. The current study responded to this need by evaluating a biodata inventory administered via IVR technology. A predictive validity study revealed that both a 42-item biodata measure and a more parsimonious 6-item composite correlated with supervisor ratings of performance and did not result in adverse impact or differential prediction. In addition, a utility analysis indicated that both IVR biodata measures would likely result in considerable financial gains to the hiring organization. The implications of these results for selection research and practice are discussed.     

Confidence and Eyewitness Identifications: The Cross‐Race Effect,Decision Time and Accuracy

Participants encountered same‐race and cross‐race faces at encoding, completed a series of line‐up identification tests and provided confidence ratings by using one of nine different confidence scales. Confidence was less well calibrated with identification accuracy when participants selected a cross‐race than a same‐race face because of overconfidence. By contrast, there was no cross‐race effect on confidence–accuracy calibration when participants responded ‘not present’. Whereas confidence was a very strong predictor of accuracy for fast identifications of a line‐up face, this was much less the case for slower decisions. Highly confident identifications showed a dramatic drop in accuracy from faster decisions to slower decisions, whereas there was little change in accuracy between faster and slower decisions for moderately confident or weakly confident identifications. Finally, we observed little influence of the format of the nine different confidence scales: numerical and verbal scales produced comparable calibration scores, as did scales with few or many points.

Conflicting demands of abstract and specific visual object processing resolved by frontoparietal networks

Object categorization and exemplar identification place conflicting demands on the visual system, yet humans easily perform these fundamentally contradictory tasks. Previous studies suggest the existence of dissociable visual processing subsystems to accomplish the two abilities—an abstract category (AC) subsystem that operates effectively in the left hemisphere and a specific exemplar (SE) subsystem that operates effectively in the right hemisphere. This multiple subsystems theory explains a range of visual abilities, but previous studies have not explored what mechanisms exist for coordinating the function of multiple subsystems and/or resolving the conflicts that would arise between them. We collected functional MRI data while participants performed two variants of a cue–probe working memory task that required AC or SE processing. During the maintenance phase of the task, the bilateral intraparietal sulcus (IPS) exhibited hemispheric asymmetries in functional connectivity consistent with exerting proactive control over the two visual subsystems: greater connectivity to the left hemisphere during the AC task, and greater connectivity to the right hemisphere during the SE task. Moreover, probe-evoked activation revealed activity in a broad frontoparietal network (containing IPS) associated with reactive control when the two visual subsystems were in conflict, and variations in this conflict signal across trials was related to the visual similarity of the cue–probe stimulus pairs. Although many studies have confirmed the existence of multiple visual processing subsystems, this study is the first to identify the mechanisms responsible for coordinating their operations.     

Effects of negative incentive shifts in food reward on rats' consumption of concurrent ethanol solutions

Frustration stress, typically operationalized as the unexpected loss of reinforcement, has been shown to engender substance use. Abrupt reductions in reinforcer magnitude likely also function as frustration stressors. These negative incentive shifts were previously shown to produce tap‐ and sweetened‐water drinking in rats. The purpose of this study was to investigate whether these shifts in food reward would occasion oral ethanol self‐administration. Nine male Long‐Evans rats operated on a two‐component multiple fixed‐ratio schedule with signaled components producing either a large (4 pellets) or small (1pellet) reinforcer. Components were pseudorandomly arranged to present 4 transitions between past and upcoming reinforcer magnitudes: small‐to‐large, small‐to‐small, large‐to‐large, and large‐to‐small (negative incentive shift). Experiment 1 investigated the effects of negative incentive shifts on consumption of concurrent, freely available 10% sucrose, 10% sucrose plus 10% ethanol, and following sucrose fading, 10% ethanol. Experiment 2 entailed continuation of schedule contingencies with a dose manipulation of 4 ethanol concentrations (0, 5, 10, and 20%) to assess dose‐dependent differences in transition‐type control and consumption. A lever‐press extinction condition was then conducted with 10% ethanol availability. In this novel model of frustration stress, negative incentive shifts prompted ethanol self‐administration at each dose investigated, whereas the other transitions did not.
