A cognitive‐emotional account of the shape of the probability weighting function

Research has shown a tendency of decision makers to overweight small probabilities and to underweight moderate and large probabilities. In standard treatments this is graphically modeled by an inverse S‐shaped probability weighting function. We suggest that emotions play a significant role in the shaping of the probability weighting function. In particular, the weighting function is proposed to be some function of objective probability, expected elation, and expected disappointment. The overweighting of small probabilities results from the anticipated elation after having won, given that winning was very unlikely. The underweighting of large probabilities results from anticipated disappointment after having failed to win, given that winning was very likely. Hence, probability is assumed to influence utility. Three experiments investigate these hypotheses. Experiments 1 and 2 show that a convex function relates probability to surprise. Experiment 3 elicits choice data and further supports the proposed hypotheses. The model adds to the understanding of the cognitive and emotional processes underlying the shape of the probability weighting function. Copyright © 2002 John Wiley & Sons, Ltd.     

Entwicklungstendenzen psychotherapeutischer Praxis und Forschung

This review presents an analysis of articles in the journal “Psychotherapeut” during the years 2000 and 2001 with the focus on new efforts in the field of psychotherapeutic practice and research. The main topics of the journal are the presentation of new therapeutic approaches, some of them integrating different theoretical orientations, and the emphasis on the therapeutic relationship as a specific contribution to the process and the results of psychotherapy. In addition, this article presents a survey of the various subjects in psychotherapeutic research including a) the application and testing of new questionnaires to measure the effectiveness and the process of psychotherapy and b) research in the epidemiology of selected forms of stress, their consequences and lasting effects.     

“You be Sure Now to be Honest in Your Assessment”: Teaching and Learning Self-Assessment

When taking part in the everyday practices of the school, the pupil ‘metalearns’ implicit institutional knowledge about educability and its proper criteria. The aim of this study was to examine one important school practice, self-assessment: How is self-assessment ‘taught’ to children, what is assessed through the self-assessment method, how is self-assessment introduced to children, and how do they perceive those situations? The ethnographic research focused on the classroom situations of one class of first-graders during one autumn term. The data were collected by means of regular observation, video recordings, short interviews, documents, and informal conversations with the teachers, pupils and parents. The findings indicated that the frequency of self-assessment episodes was particularly high in the domains of writing, mathematics, and social skills and behaviour; self-assessment situations were a ‘natural’ part of everyday teaching practices. According to our observations, the result of the self-assessment was considerably explicit. The teacher made sure that the pupils assessed their performance in the way she wanted. The teaching of self-assessment also teaches the child what assessment criteria the school regards as important and how well the child fulfils these criteria. According to our analysis, these important assessment criteria are objectiveness (compliance to standard), honesty, and individuality (a product that ‘looks like’ its author). The children practised self-assessment actively and were apparently capable of assessing their own performance. Our results suggest that ‘the self’ in self-assessment is paradoxical: you can assess yourself as long as you assess the right things in the right way.     

Hearing Impairment, Coping Strategies, and Anxiety Sensitivity

The aim was to study coping strategies among hearing-impaired individuals by using a validated coping instrument—The Ways of Coping Questionnaire (WOCQ; S. Folkman & R. Lazarus, 1988)—and to relate the use of coping with anxiety sensitivity and experience of hearing impairment. A questionnaire booklet was sent out to the members of the local branch of the Swedish Hard of Hearing Association. Ninety-four members responded to the questionnaire, yielding a 53% response rate. Primary outcome measures were the WOCQ, the Anxiety Sensitivity Index, and visual analogue scale rating of discomfort from hearing impairment. Repeated measures analysis of WOCQ subscales showed that the participants used planful problem solving and self-controlling coping strategies whereas escape/avoidance responses were less frequently used than the other coping strategies. Anxiety sensitivity was associated with escape/avoidance coping (r = .63, p < .0001). In conclusion, hearing-impaired individuals do not use escape/avoidance coping more than other coping strategies. However, escape/avoidance coping is associated with anxiety sensitivity, suggesting that sensitivity to anxiety sensations is an important associated factor. Coping strategies were not associated with discomfort from hearing impairment in any meaningful way.     

Musiktherapie in der deutschen Psychosomatik

The authors report about the clinical implementation of music therapy in psychosomatic hospitals in FRG based on a survey among practising music therapists: attending especially to the qualification of music therapists, their integration and the problem of indication. The coverage of music therapy in the standard textbooks on psychosomatic medicine is discussed.Finally the state of research on music therapy in psychosomatic hospitals is reviewed.     

Virtual reality and the new psychophysics

Virtual reality (VR) promises methodological rigour with the extra benefit of allowing us to study the context-dependent behaviour of individuals in their natural environment. Pan and Hamilton (2018, Br. J. Psychol.) provide a useful overview of methodological recommendations for using VR. Here, we highlight some other aspects of the use of VR. Our first argument is that VR can be useful by virtue of its differences from the normal perceptual environment. That is, by virtue of its relative non-realism and poverty of its perceptual elements, it can actually offer increased clarity with respect to the features of interest for the researcher. Our second argument is that VR exerts its measurable influence more by eliciting an acceptance of the virtual world (i.e., ‘suspension of disbelief’) rather than by eliciting a true belief of the realism of the VR environment. We conclude by providing a novel suggestion for combining neuroimaging methods with embodied VR that relies on the suspension of disbelief.
