Effects of traumatic stress and perceived stress on everyday cognitive functioning

Stressful or traumatic events have been shown to impair cognitive functioning on laboratory-based tasks due to stress-related intrusive thoughts and avoidance. However, research on the effects of stress on everyday cognitive functioning has been lacking. A sample of 909 undergraduates completed measures of perceived stress, PTSD symptoms, and everyday cognitive failures. The results revealed that both perceived stress and PTSD symptoms uniquely predicted cognitive failures, even after controlling for a number of potentially confounding variables. Additionally, there was a significant interaction. Participants with low scores on both measures of stress reported the fewest occurrences of everyday cognitive failures. In contrast, participants with elevated scores on either measure of stress reported higher levels of cognitive failures. These results suggest that there are unique negative effects of perceived stress and PTSD symptoms on everyday cognitive functioning and sharpen our understanding of the relationship between stress and cognition.     

Training fast and frugal heuristics in military decision making

Fast and frugal heuristics have been used to model decision making in applied domains very effectively, suggesting that they could be used to improve applied decision making. We developed a fast and frugal heuristic for infantry decisions using experts from the British Army. This was able to predict around 80% of their decisions using three cues. Next, we examined the benefits of learning to use the fast and frugal heuristic by training junior officers in the British Army to apply the heuristic and assessing their accuracy and mental workload when making decisions. Their performance was compared to a control condition of junior officers who applied standard military decision methods. Participants using the fast and frugal heuristic made decisions as accurately as participants in the control condition, but with reduced mental demand. This demonstrates that fast and frugal heuristics can be learnt and are as effective as analytic decision methods.     

Self-awareness and self-monitoring of cognitive and behavioral deficits in behavioral variant frontotemporal dementia, primary progressive aphasia and probable Alzheimer's disease

Lack of insight is a core diagnostic criterion for behavioral variant frontotemporal dementia (bvFTD), and is believed to be intact in the early stages of primary progressive aphasia (PPA). In other neurological conditions, symptom-specific insight has been noted, with behavioral symptoms appearing especially vulnerable to reduced insight. Different components of insight, self-awareness and self-monitoring, are also often considered separate phenomena. The current study compared insight in patients with PPA, bvFTD, and probable Alzheimer's disease (PrAD) and a group of cognitively intact control subjects. Additionally, differences in insight for the domains primarily affected by the three types of dementia, namely, Behavior, Naming, and Memory, were assessed, and self-awareness and self-monitoring were compared. A total of 55 participants were enrolled. Participants were asked to complete self-estimate scales demonstrating their perceived ability immediately prior to, and immediately following a test in each domain of interest. Results indicated that PPA and normal control groups performed very similarly on control (Weight and Eyesight) and cognitive domains, whereas bvFTD and PrAD patients were unable to accurately assess Memory. All three diagnostic groups failed to accurately assess their behavioral symptoms, suggesting that this domain is vulnerable to loss of insight across diagnoses. Naming ability, in contrast, was either accurately assessed or underestimated in all groups. Finally, there were no notable differences between self-awareness and self-monitoring, potential explanations for this are examined.     

The relationship between self-control and health: The mediating effect of avoidant coping

Trait self-control is related to a number of positive outcomes, including mental health, interpersonal success, academic success and health-related behaviours. This study sought to explore the relationships between self-control, reports of mental and physical health symptoms and coping styles. The results revealed that higher self-control was related to fewer mental and physical health symptoms and less avoidance coping. There was not a significant relationship between self-control and problem-focused or emotion-focused coping styles. Further, the relationships between self-control and mental and physical health outcomes were partially mediated by avoidance coping style. Specifically, the data suggest lower self-control is associated with unhealthy coping strategies (avoidance coping), which in turn are associated with worse mental health outcomes and greater reports of physical health symptoms. Thus lower trait self-control can serve as an indicator, suggesting circumstances in which individuals' tendencies to engage in unhealthy coping strategies are increased. These findings add to a growing body of literature underscoring the importance of trait self-control.     

Deceived and distorted: game outcome retrospectively determines the reported time of action

Previous work suggested the association between intentionality and the reported time of action was exclusive, with intentionality as the primary facilitator to the mental time compression between the reported time of action and its effect (Haggard, Clark, & Kalogeras, 2002). In three experiments, we examined whether mental time compression could also be observed in an unintended action. Participants performed an externally cued key press task that elicited one of two possible tones. The reported time of action shifted closer to the tone when the tone was used to indicate the winner of a race (Exp.2) compared to when the tone was meaningless and did not indicate winning (Exp.1). This suggests that reported time of an unintended action could shift toward the effect in some contexts. Furthermore, the results from Exp.2 and Exp.3 (tones were substituted with verbal feedback) showed that a presumed winning action was judged to occur earlier whereas a presumed losing action was judged to be later. These findings therefore support the view that the reported time of action is reconstructed from known temporal information rather than determined by intentionality.     

Predictors of successful discharge from out-of-home care among children with complex needs

We examined the predictors for successful discharge from out-of-home care of children with complex needs placed in a novel comprehensive service intervention (Manatee Model) and compared their discharge experiences to their out-of-home counterparts from the same county. The study design consisted of a longitudinal two-year comparison of these two groups. A total of 147 cases were included in the analysis, and the propensity scoring technique was used to equate the groups. Among children admitted to the Manatee Model, boys, White children, younger children, those who came from a single-parent family, those who were abused, and those who had a disability (physical or emotional disability or medical condition) were found less likely to successfully exit within the two years when these predictors were examined separately. Multivariate analyses indicated that only age at the time of removal and health status were significantly associated with successful discharge. Implications of the findings are discussed.     

REBT Used with Children and Adolescents who have Emotional and Behavioral Disorders in Educational Settings: A Review of the Literature

This article discusses the need for a comprehensive intervention strategy for students who experience difficulty managing self-defeating emotions and behaviors in educational settings. The review of the literature identifies related research and describes how the application of Rational Emotive Behavior Therapy (REBT), as a comprehensive educational intervention, has been implemented with children and adolescents who have been identified as having emotional disturbance in various educational settings.     

Dialectical Behavior Therapy Techniques for Counseling Incarcerated Female Adolescents: A Case Illustration

Dialectical behavior therapy (DBT) may successfully address the needs of female juvenile offenders, but systemic barriers prohibit adherence to the full DBT protocol. The authors built a rationale for using select DBT techniques with female adolescent offenders and provided a case illustration.
