Cognitive neutralising strategies and their use across differing stressor types

Abstract

Three studies are described which investigate the kinds of strategies that individuals use to devalue the threatening meaning of a stressor (cognitive neutralising strategies, CNS). These studies identified seven factorially independent constructs corresponding to Downward Comparison, Positive Reappraisal, Cognitive Disengagement, Optimism, Faith in Social Support, Denial and Life Perspective. The use of CNS was highly correlated with the use of problem-focused coping strategies regardless of stressor type, but associated with the use of avoidance coping and emotion-focused coping only in the case of certain stressor types. The role of CNS in the coping process is discussed in the light of the present results.     

Anxiety sensitivity and distress tolerance typologies and relations to posttraumatic stress disorder: A cluster analytic approach

A growing literature suggests a relationship between a high anxiety sensitivity (AS; the fear of anxiety and its related consequences)/low distress tolerance (DT; the capacity tolerate internal negative states) profile and posttraumatic stress disorder (PTSD) symptoms. However, specific profiles have not been identified or examined specifically in Veteran samples. Thus, the aims of the present study were to establish empirically derived profiles created from response patterns on the Anxiety Sensitivity Index and Distress Tolerance Scale and to examine associations with PTSD symptom clusters among a sample of combat-exposed Veterans (N = 250). A cluster analytic approach was used to identify AS/DT profiles, and a series of multivariate analyses of variance with post hoc analyses was conducted to examine the relationship between each AS/DT profile and each PTSD symptom cluster. Results indicated a 3-cluster solution including a high AS/low DT “at risk” profile, a low AS/high DT “resilient” profile, and an average AS/DT “intermediate” profile. The at-risk profile was associated with significantly greater symptoms in each PTSD cluster (i.e., hyperarousal, avoidance, re-experiencing) when compared to the other two profiles. The at-risk profile was also associated with greater depressive symptoms and lower self-reported resilience. These findings extend the previous literature by identifying a high AS/low DT “at risk” profile and its associations with PTSD symptoms, underscoring the potential utility in targeting these affect-regulation constructs for clinical intervention.     

Assessment of Occupational Burnout in United States Air Force Predator/Reaper “Drone” Operators

This study investigates the self-reported levels of occupational burnout among 1,094 U.S. Air Force drone operators stationed within the borders of the United States who are supporting a wide range of around-the-clock military surveillance and weapons strike missions across the globe. Data were gathered from a Web-based survey of demographic items and the Maslach Burnout Inventory assessing the facets of occupational burnout (exhaustion, cynicism, and professional efficacy). The overall survey response rate was 49%. Approximately 20% reported high levels of exhaustion, and 11% reported high levels of cynicism, but only 3% reported low levels of professional efficacy. Predictors of exhaustion, as well as between group differences, were identified along with recommendations for performance improvement and mitigating risks to safety.

Asking Parents to Prepare Children for an Event: Altering Parental Instructions Influences Children's Recall

The authors investigated whether manipulating parents' goals regarding their discussion of an upcoming staged event with their 6-year-old children differentially influenced the children's recall. Parents (n = 62) were asked to prepare their child for a staged novel event—“visiting the pretend zoo”—to take place 1 day later. One group (inform) was asked to simply tell their child about the event, whereas a second group (discuss) was asked to engage their child in conversation and seek their child's perspective. A third group of parents (control) read an unrelated story to their child. Relative to parents in the control and inform conditions, parents in the discuss condition engaged their children in richer, more diverse, and complex conversation and their children made more contributions to the conversation. When their recall was tested 1 week later, however, children in the inform condition, relative to the discuss and control conditions, recalled more correct information overall. The reports of children in the inform and discuss conditions were highly accurate, and more so than those of children in the control condition. The findings and their possible underlying mechanisms are discussed.     

Error-related psychophysiology and negative affect

The error-related negativity (ERN/Ne) and error positivity (Pe) have been associated with error detection and response monitoring. More recently, heart rate (HR) and skin conductance (SC) have also been shown to be sensitive to the internal detection of errors. An enhanced ERN has consistently been observed in anxious subjects and there is some suggestion that the ERN is related to general negative affective experience (NA). The ERN has been source localized to the anterior cingulate cortex-a structure implicated in the regulation of affective, response selection, and autonomic resources. Thus, the findings that autonomic measures and affective distress are related to response monitoring are consistent with anterior cingulate cortex function. In the present experiment, we sought to evaluate more comprehensively the relationship between self-reported negative affect and error-related physiology in a between-groups design. Results indicate that high NA was associated with significantly greater ERN and error-related SCR, and smaller Pe. These results are discussed in terms of anterior cingulate cortex function, psychopathology, and response monitoring.     

Multiple memory systems: the power of interactions

Two relatively simple theories of brain function will be used to demonstrate the explanatory power of multiple memory systems in your brain interacting cooperatively or competitively to directly or indirectly influence cognition and behaviour. The view put forth in this mini-review is that interactions between memory systems produce normal and abnormal manifestations of behaviour, and by logical extension, an understanding of these complex interactions holds the key to understanding debilitating brain and psychiatric disorders.     

The relative deprivation-gratification continuum and the attitudes of South Africans toward immigrants: a test of the V-curve hypothesis

It has long been established that there is a linear and positive relationship between relative deprivation and prejudice. However, a recent experiment suggests that the converse of relative deprivation, relative gratification, may also be associated with prejudice (S. Guimond & M. Dambrun, 2002). Specifically, the evidence suggests that the usual test for a linear relationship between relative deprivation-gratification and prejudice might conceal the existence of a bilinear relationship. This function, labeled the V-curve hypothesis, predicts that both relative deprivation and relative gratification are associated with higher levels of prejudice. This hypothesis was tested with a representative sample of South Africans (N=1,600). Results provide strong support for the V-curve hypothesis. Furthermore, strength of ethnic identification emerged as a partial mediator for the effect of relative gratification on prejudice.     

Multiple parallel memory systems in the brain of the rat

A theory of multiple parallel memory systems in the brain of the rat is described. Each system consists of a series of interconnected neural structures. The "central structures" of the three systems described are the hippocampus, the matrix compartment of the dorsal striatum (caudate-putamen), and the amygdala. Information, coded as neural signals, flows independently through each system. All systems have access to the same information from situations in which learning occurs, but each system is specialized to represent a different kind of relationship among the elements (stimulus events, responses, reinforcers) of the information that flows through it. The speed and accuracy with which a system forms a coherent representation of a learning situation depend on the correspondence between the specialization of the system and the relationship among the elements of the situation. The coherence of these stored representations determines the degree of control exerted by each system on behavior in the situation. Although they process information independently the systems interact in at least two ways: by simultaneous parallel influence on behavioral output and by directly influencing each other. These interactions can be cooperative (leading to similar behaviors) or competitive (leading to different behaviors). Experimental findings consistent with these ideas, mostly from experiments with rats, are reviewed.     

Toward an appropriate baseline for measures of eye movement behavior during reading

In empirical studies of human eye movement behavior during reading, it is common to compute various summary measures from the data, but these measures are typically not evaluated with respect to corresponding measures of baseline performance. The authors present a method for deriving an appropriate baseline by mapping the actual behavior to a random perturbation of the text being read, and they find surprising similarities between the baseline and the empirical data. The practical message from these findings is that the importance of a particular factor in explaining either empirical or simulated eye movement patterns should be evaluated using an appropriate baseline. In addition to this methodological point, the authors suggest that eye movement behavior in reading may be constrained by the properties of an eye-guidance system that has adapted to the coarse-grained statistical properties of written language.
