Preparatory processes in the task-switching paradigm: evidence from the use of probability cues

The purpose of the investigations was to dissociate processes of task preparation from task execution in the task-switching paradigm. The basic assumption was that task repetitions have 2 advantages over task shifts: an activation advantage as a result of the execution of the same task type in the pretrial, and an expectation advantage, because participants, in general, implicitly expect a repetition. In Experiments 1-3, the authors explicitly manipulated expectancies by presenting cues that announced a shift and/or a repetition with probabilities of 1.00, .75, .50, or .25. Increasing latencies with decreasing probability for shifts and repetitions show that the expectation advantage can be equalized by preparation. However, the activation advantage represented by constant shift costs between tasks of the same probability is not penetrable by preparation. In Experiments 4 and 5, the authors found evidence that preparation involves activation of the expected task and inhibition of distracting tasks.     

Emotion und Psychotherapie

Considering the fact that all psychic disturbances are emotional disturbances as well, we develop based on our research on the modular structure of the emotional system a systematisation of the disturbance-specific concatenation of these modules within the patient’s social relationships. Subsequently, we discuss treatment possibilities and contraindications for each clinical empirically validated constellation. We describe a fundamental mechanism of affect induction keeping the disturbances alive and transporting them to the next generation. We conclude in stating that treatment recommendations focusing on a standard algorithm of handling the emotions system fail because there is no general indication for such enterprises.     

Optimism, pessimism, and change of psychological well-being in cancer patients

Whereas most previous studies have assessed optimism/pessimism as a unidimensional construct, there is increasing awareness that optimism and pessimism may represent two partially independent dimensions. In this study, the role of optimism and pessimism for the maintenance of psychological well-being was assessed in 161 newly diagnosed cancer patients. Before the start of chemotherapy, more positive affect balance was associated with higher optimism and lower pessimism. Over the course of 9 months following diagnosis, pessimism predicted negative change in affect balance, whereas no effect of optimism appeared. Higher levels of perceived side-effects of chemotherapy were associated with negative change in affect balance. However, an interaction effect of perceived side-effects with pessimism indicated that this was only the case in patients with above-median levels of pessimism. The conclusion is drawn that it may be more important to be less pessimistic than to be optimistic when diagnosed with cancer.

Coping with occupational uncertainty and formal volunteering across the life span

Common wisdom suggests that individuals confronted with occupational uncertainty (e.g., job insecurity and difficulties with career planning) may withdraw from volunteering. We argue that volunteering may be useful to workers in some career stages and that stage-appropriate coping with occupational uncertainty may increase individuals' readiness to volunteer. In Study 1, we used cross-sectional and 1-year follow-up data from Germany that covered three age groups: 16–29 (N_T1 = 1253, N_T2 = 224), 30–43 (N_T1 = 1560, N_T2 = 371), and 56–75 (N_T1 = 518, N_T2 = 215). High engagement and low disengagement in coping with occupational uncertainty were associated with concurrent volunteering in the youngest group but not in the other groups. Over 1 year, high disengagement reduced the likelihood of starting volunteering in the youngest group and increased this likelihood in the oldest group. Study 2 used an independent, cross-sectional German sample that included two age groups: 20–29 (N = 326) and 30–40 (N = 367). Using a different measure of volunteering, Study 2 partly replicated the cross-sectional findings from Study 1. Results suggest that individual agency is a decisive link between occupational uncertainty and the readiness to volunteer, particularly among young labor market entrants.     

You'd Better Ask an Expert: Mitigating the Comprehensibility Effect on Laypeople's Decisions About Science‐Based Knowledge Claims

Research shows that laypeople rely more on their capabilities to make decisions about science‐based knowledge claims after reading comprehensible compared with less comprehensible topic information. This can be problematic, because complex science‐based issues usually cannot be understood fully without experts' further advice. The present study investigated whether making readers aware of the ‘epistemic topic complexity’ of an issue (i.e., the extent of existing topic knowledge, the complexity of relationships between concepts, and the existence of multiple expert perspectives) can mitigate this influence of comprehensibility. Undergraduate students read comprehensible or less comprehensible health texts with topic knowledge being described as complex, uncomplex, or not described at all. They reported whether they agreed with the claim and would rely on their decision. Results showed that after reading comprehensible information, participants' reliance on their decision increased less when they considered topic knowledge to be complex. Practical implications of the findings are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Nichtspezifische,funktionelle und somatoforme Körperbeschwerden

In the S3 guidelines on non-specific, functional and somatoform bodily complaints, a broad group of medical and psychological societies as well as patient representatives have for the first time achieved an evidence-based consensus on terminology and care of these patients. This paper summarizes the main background information and recommendations for psychotherapists. For mild courses treatment by the general practitioner with establishment of a biopsychosocial explanatory model and physical as well as social activation is usually sufficient. More severe courses call for cooperative, coordinated management, including regular appointments with the general practitioner, graded activation and psychotherapy, especially cognitive behavioral, in addition to psychodynamic interpersonal or hypnotherapeutic imaginative psychotherapy. In particularly severe courses multimodal and if necessary day clinic or inpatient treatment is needed. Additionally the patient guidelines for affected people and their relatives are presented.     

Why Do Members of Disadvantaged Groups Strike Back at Perceived Negativity Towards the In‐group?

Against the background of riots in communities across London in 2011, this paper examines the implications of negative meta‐stereotypes on stigmatized group members' reactions towards members of privileged out‐groups within their communities. We hypothesized that concerns over negative opinions that the dominant out‐group is expected to hold of the in‐group (i.e. meta‐stereotypes) would be negatively associated with group members' perceptions of societal fairness and that this relationship would be mediated by members' recall of personal experiences with discrimination. We further hypothesized that views about societal fairness that are challenged in this way would lower an inclination to express discontent with the status quo via normative means while at the same time, increase nonnormative expressions. Results from two surveys (study 1, N = 50; study 2, N = 132) provided support for these hypotheses and are discussed in terms of their meaning for community relations.
