All in the mind's eye? Anger rumination and reappraisal

Research on rumination has demonstrated that compared with distraction, rumination intensifies and prolongs negative emotion. However, rumination and distraction differ both in what one thinks about and how one thinks about it. Do the negative outcomes of rumination result from how people think about negative events or simply that they think about them at all? To address this question, participants in 2 studies recalled a recent anger-provoking event and then thought about it in 1 of 2 ways: by ruminating or by reappraising. The authors examined the impact of these strategies on subsequent ratings of anger experience (Study 1) as well as on perseverative thinking and physiological responding over time (Study 2). Relative to reappraisal, rumination led to greater anger experience, more cognitive perseveration, and greater sympathetic nervous system activation. These findings provide compelling new evidence that how one thinks about an emotional event can shape the emotional response one has.     

Sleep in children improves memory performance on declarative but not procedural tasks

Sleep supports the consolidation of memory in adults. Childhood is a period hallmarked by huge demands of brain plasticity as well as great amounts of efficient sleep. Whether sleep supports memory consolidation in children as in adults is unclear. We compared effects of nocturnal sleep (versus daytime wakefulness) on consolidation of declarative (word-pair associates, two-dimensional [2D] object location), and procedural memories (finger sequence tapping) in 15 children (6-8 yr) and 15 adults. Beneficial effects of sleep on retention of declarative memories were comparable in children and adults. However, opposite to adults, children showed smaller improvement in finger-tapping skill across retention sleep than wakefulness, indicating that sleep-dependent procedural memory consolidation depends on developmental stage.     

Fear conditioning in posttraumatic stress disorder: evidence for delayed extinction of autonomic, experiential, and behavioural responses

Aversive conditioning has been proposed as an important factor involved in the etiology of posttraumatic stress disorder (PTSD). However, it is not yet fully understood exactly which learning mechanisms are characteristic for PTSD. PTSD patients (n=36), and healthy individuals with and without trauma exposure (TE group, n=21; nTE group, n=34), underwent a differential fear conditioning experiment consisting of habituation, acquisition, and extinction phases. An electrical stimulus served as the unconditioned stimulus (US), and two neutral pictures as conditioned stimuli (CS+, paired; CS-, unpaired). Conditioned responses were quantified by skin conductance responses (SCRs), subjective ratings of CS valence and US-expectancy, and a behavioural test. In contrast to the nTE group, PTSD patients showed delayed extinction of SCRs to the CS+. Online ratings of valence and US-expectancy as well as the behavioural test confirmed this pattern. These findings point to a deficit in extinction learning and highlight the role of affective valence appraisals and cognitive biases in PTSD. In addition, there was some evidence that a subgroup of PTSD patients had difficulties in learning the CS-US contingency, thereby providing preliminary evidence of reduced discrimination learning.     

Perceived teasing experiences in body dysmorphic disorder

Individuals with body dysmorphic disorder (BDD) are excessively concerned about imagined or slight defects in their appearance (e.g., asymmetrical facial features). Cognitive-behavioral models of BDD propose that several factors, including dysfunctional appearance-related beliefs and life experiences, such as teasing, contribute to the avoidance behaviors or rituals (e.g., mirror checking, grooming) characteristic of BDD. Previous research has demonstrated an association between perceived teasing and body dissatisfaction. In the current study, we examined whether individuals with BDD (n = 16) report to have been teased more often than do mentally healthy controls (n = 17). The group comprising individuals with BDD reported more appearance- and competency-related teasing than did control participants. This study provides preliminary evidence for the association between perceived teasing and BDD.     

The structure of cockpit management attitudes

A revised version of the Cockpit Management Attitudes Questionnaire (CMAQ) is introduced. Factor analyses of responses from 3 different samples reveal comparable factor structure (previous attempts to factor analyze this measure had produced equivocal results). Implications for the measurement of attitudes and the assessment of attitude change are discussed. It is argued that the CMAQ will benefit both special training programs and efforts to explore attitude-performance linkages in air-transport operations.     

Selbst das selbst ist nicht selbst

EVEN SELF IS WITHOUT SELF. The Buddhist triad of body, speech and mind and the concept of self as their function are analysed from an analytic philosopher;s point of view. Buddhism is seen as an empirical religion with intersubjective operationalisations of its concepts. The mind is not observable but can be found by empirical methods in the traces of its actions, which can be found in the utterances of speech. Semantical and other paradoxes do not permit the location of mind within the hierarchy of languages. Mind has an active aspect by choosing a suitable frame of reference for every activity of the aspect of speech and is thus irreducible to that aspect. Mind is the space, the essence, indescribable by language, of possible frames of reference for perception and cognition. This absolute aspect of the mind corresponds to an absolute aspect of the self, unique by identitas indiscernibilium, which cannot be perceived, but can be found by the exercise of awareness; while the relative self corresponds to the individual form of cognition and does not therefore presuppose a semantical regress of ever richer metalanguages.     

Technical improvements to the projection tachistoscope

Three disadvantages of the usual projection tachistoscope are discussed. Because of low mechanical precision, stimulus alignment is difficult. Because of rather low focal distances of the projection lenses, the stimuli provide visual angles that are often larger than desired, and the photographic shutters are noisy, are relatively inert, and have a limited service life. A new construction is described that avoids these disadvantages with a modified configuration of commercial elements: stable and precise mounting of the single channels, a double-lens projection system, and a noiseless, fast mechanical shutter based on a limited-rotation motor.
