Symptomattributionsstile bei Hypochondrie

Background

Somatic symptom attributions are of central importance in cognitive-behavioral models of the development, maintenance and treatment of hypochondriasis. However, the mode of symptom attribution has rarely been systematically investigated in these patients. Is a somatic mode of symptom attribution indeed specific for hypochondriasis and furthermore, how strongly is it associated with “doctor shopping”, a typical behavioral consequence of hypochondriasis?

Patients and methods

In this study 88 hypochondriacal, 52 depressive and 52 healthy persons were asked to complete the symptom interpretations questionnaire and several standardized symptom questionnaires. They also took part in two structured clinical interviews for the diagnosis of hypochondriasis and various other psychological disorders according to DSM-IV.

Results

Somatic symptom attributions were associated specifically with hypochondriasis, while normalizing attributions characterized persons with low health anxiety. When examined as predictors in multiple regression models, in particular somatic attributions and the total of somatoform complaints predicted the intensity of health anxiety (R ²?=?0.69) and “doctor shopping” (R ²?=?0.48).

Conclusion

In the cognitive-behavioral treatment of hypochondriasis, patients should be encouraged to test normalizing explanations as alternatives to habitual somatic attributions of somatic disturbances.     

Kant's Pragmatism

This article offers a definition of the term ‘pragmatic’, as it is used in Kant's Critique of Pure Reason. The definition offered does not make any reference to the affinities between Kant's pragmatism and the philosophies of the American or other pragmatists but draws its definiens entirely from the Kantian conceptual framework. It states that the term ‘pragmatic’ denotes imperatives, laws and beliefs of a specific type: an imperative is pragmatic if and only if it is concerned with the choice of means to individual or universal happiness; a law is pragmatic if and only if our willingness to presuppose it results from our obedience to a pragmatic imperative; and a belief is pragmatic if and only if it relates to the objective validity of pragmatic laws. This article also discusses two rival definitions of the term ‘pragmatic’ (as used by Kant) that have been brought forward by Sidney Axinn and Nicholas Rescher.     

Persuasive Effects of Fictional Narratives Increase Over Time

Fact-related information contained in fictional narratives may induce substantial changes in readers' real-world beliefs. Current models of persuasion through fiction assume that these effects occur because readers are psychologically transported into the fictional world of the narrative. Contrary to general dual-process models of persuasion, models of persuasion through fiction also imply that persuasive effects of fictional narratives are persistent and even increase over time (absolute sleeper effect). In an experiment designed to test this prediction, 81 participants read either a fictional story that contained true as well as false assertions about real-world topics or a control story. There were large short-term persuasive effects of false information, and these effects were even larger for a group with a 2-week assessment delay. Belief certainty was weakened immediately after reading but returned to baseline level after 2 weeks, indicating that beliefs acquired by reading fictional narratives are integrated into real-world knowledge.     

Transportation and Need for Affect in Narrative Persuasion: A Mediated Moderation Model

Two experiments investigated the idea that individual differences in need for affect are critical for narrative persuasion. Need for affect, that is, the disposition to approach emotions, was assumed to facilitate the experience of being transported into the mental world of the narrative. An intense experience of transportation, in turn, should enhance the persuasive impact of narrative information on readers' beliefs. A mediated moderation analysis was used to test these assumptions. In both experiments (N = 314), need for affect (approach) and transportation moderated the persuasive effects of a fictional narrative compared to a belief-irrelevant control story (Experiment 1) and the persuasive effects of a story with high emotional content compared to a story with low emotional content (Experiment 2). The moderator effects of need for affect were shown to be mediated by the moderator effects of transportation. In sum, the magnitude of a person's need for affect determines whether and to what extent the person experiences transportation into the story world and is persuaded by the information presented in the narrative.     

Music and aggression: the impact of sexual-aggressive song lyrics on aggression-related thoughts, emotions, and behavior toward the same and the opposite sex

Three studies examined the impact of sexual-aggressive song lyrics on aggressive thoughts, emotions, and behavior toward the same and the opposite sex. In Study 1, the authors directly manipulated whether male or female participants listened to misogynous or neutral song lyrics and measured actual aggressive behavior. Male participants who were exposed to misogynous song lyrics administered more hot chili sauce to a female than to a male confederate. Study 2 shed some light on the underlying psychological processes: Male participants who heard misogynous song lyrics recalled more negative attributes of women and reported more feelings of vengeance than when they heard neutral song lyrics. In addition, men-hating song lyrics had a similar effect on aggression-related responses of female participants toward men. Finally, Study 3 replicated the findings of the previous two studies with an alternative measure of aggressive behavior as well as a more subtle measure of aggressive cognitions. The results are discussed in the framework of the General Aggression Model.     

Recognition is used as one cue among others in judgment and decision making

Three experiments with paired comparisons were conducted to test the non-compensatory character of the recognition heuristic (D. G. Goldstein & G. Gigerenzer, 2002) in judgment and decision making. Recognition and knowledge about the recognized alternative were manipulated. In Experiment 1, participants were presented pairs of animal names where the task was to select the animal with the larger population. In Experiment 2, participants chose the safer 1 out of 2 airlines, and 3 knowledge cues were varied simultaneously. Recognition effects were partly compensated by task-relevant knowledge. The compensatory effects were additive. Decisions were slower when recognition and knowledge were incongruent. In Experiment 3, compensatory effects of knowledge and recognition were found for the city-size task which had originally been used to demonstrate the non-compensatory character of the recognition heuristic. These results suggest that recognition information is not used in an all-or-none fashion but is integrated with other types of knowledge in judgment and decision making.     

Dissociable contributions within the medial temporal lobe to encoding of object-location associations

The crucial role of the medial temporal lobe (MTL) in episodic memory is well established. Although there is little doubt that its anatomical subregions-the hippocampus, peri-, entorhinal and parahippocampal cortex (PHC)-contribute differentially to mnemonic processes, their specific functions in episodic memory are under debate. Data from animal, human lesion, and neuroimaging studies suggest somewhat contradictory perspectives on this functional specialization: a general participation in declarative memory, an exclusive involvement in associative mnemonic processes, and a specific contribution to spatial memory are reported for the hippocampus, adjacent cortices, and the PHC. A functional lateralization in humans dependent on the verbalizability of the material is also discussed herein. To further elucidate the differential contributions of the various MTL subregions to encoding, we employed an object-location association memory paradigm. The memory for each of the studied associations was tested twice: by the object, and by the location serving as retrieval cue. The memory accuracy in response to both cue types was also assessed parametrically. Brain activity during encoding which leads to different degrees of subsequent memory accuracy under the two retrieval conditions was compared. We found the bilateral posterior PHC to participate in encoding of both the object associated with a location and the location associated with an object. In contrast, activity in an area in the left anterior PHC and the right anterior MTL was only correlated with the memory for the location associated with an object.     

Absorption, openness to experience, and hypnotizability

Absorption, a correlate of hypnotizability, is conceptually related to openness to experience. Study 1 found no evidence that gender moderated the correlation between absorption and hypnotizability, or of nonlinear trends. Study 2 showed that openness was factorially complex, and that absorption was related to imaginative involvement, but not to social-political liberalism. Study 3 found small quadratic trends in the relations between these variables and hypnotizability; hypnotizability was related to imaginative involvement, but not liberalism. Study 4 confirmed differential correlations between absorption subscales and hypnotizability but failed to confirm the nonlinear trends. Implications for future studies of the correlates of hypnotizability, and for the nature of the "fifth factor" in personality structure, are discussed.     

How Emotional Are Populists Really? Factors Explaining Emotional Appeals in the Communication of Political Parties

Are populists really more emotional than mainstream parties? The alleged link between populism and emotional communication has barely been subject to systematic empirical scrutiny. I use literature on populist communication and appraisal theory to generate expectations about which political parties use which emotional appeals. I test these claims by applying a novel emotional dictionary to a large set of text data including more than 700,000 press releases and tweets from three European countries. As expected, I find that populist parties use significantly more negative emotional appeals (anger, fear, disgust, sadness) and less positive emotional appeals (joy, enthusiasm, pride, hope) than mainstream parties. Furthermore, I find that political actors adapt the usage of emotional appeals to different purposes depending on the communication medium and the politicians' status level. This study entails important implications for the research on emotional appeals in politics and populist communication.
