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.     

Interventionism and Supervenience: A New Problem and Provisional Solution

The causal exclusion argument suggests that mental causes are excluded in favour of the underlying physical causes that do all the causal work. Recently, a debate has emerged concerning the possibility of avoiding this conclusion by adopting Woodward's interventionist theory of causation. Both proponents and opponents of the interventionist solution crucially rely on the notion of supervenience when formulating their positions. In this article, we consider the relation between interventionism and supervenience in detail and argue that importing supervenience relations into the interventionist framework is deeply problematic. However, rather than reject interventionist solutions to exclusion wholesale, we wish to propose that the problem lies with the concept of supervenience. This would open the door for a moderate defence of the interventionist solution to the exclusion argument.     

The focus of attention in working memory: evidence from a word updating task

Three experiments examined the cognitive costs of item switching within working memory with a novel word updating task, thereby extending previous research to the field of linguistic stimuli and linguistic-graphemic updating operations. In Experiments 1 and 2 costs for switching between working memory items were evident on the word level, and they increased with an increasing word set size (Experiment 2). In contrast, a surprisingly similar switch effect on the level of letters was not affected by word set size (Experiment 2). Experiment 3 showed that this effect is not simply based on the need for re-orienting visual spatial attention. To account for the overall picture of results, a recursive model of attentional foci is proposed. Moreover, individual working memory span appears to be associated with the accuracy of item switching, but not with its speed.     

Coping with disturbances

Motion systems must cope with internal and external disturbances affecting the envisioned movement program. In science responses to disturbances are used to characterize system properties. Recently, evidence has been collected that self-stability due to the mechanical response of a system can greatly contribute to safe guarding proper operation of the system and to follow up an envisioned task. Here we review research in our laboratory on the kinematic response of standing subjects to sudden pulls inflicted by a motor, and the kinetics of runners crossing a track with a bump. We find that in both cases the first responses are dominated by system compliance. Thereby damage is avoided and the tasks are secured. Preparation to the observed disturbance does not seem to have the goal to compensate quickly but to enhance the scope of the reaction and its economy.     

Adult Age Invariance in Sentence Unitization

We examined age differences on a letter detection task that was performed on four-word sentences in order to examine how letter-level and word-level processing is integrated with sentence-level unitization. Sentence-level unitization is defined as the formation of a sentence-level code that delays access to letter-level or word-level codes. There was a consistent word-frequency disadvantage for both age groups in which it took longer to detect letters within high and medium high frequency words than in low frequency words. This finding suggested that word-level and letter-level input channels were involved in a parallel “horse race” to the central processor while simultaneously outputting codes to the sentence-level at the second tier of processing. The present data also revealed that both age groups showed a larger relative increase in reaction time for letter detection for the fourth word position compared to the third word position on syntactically “intact” sentences relative to syntactically “scrambled” sentences. These data indicated that both age groups formed sentence-level codes that made letter-level codes more difficult to access. Finally, older adults' data showed a larger cost than younger adults' data for scrambled sentences than for intact sentences. These results suggest that older adults are more reliant on a syntactical processor that facilitates the parafoveal preview during the reading of syntactically intact sentences. These data suggest that whereas there are age differences in the perceptual processing of letters and words, sentence unitization and syntactical processing remain intact with increasing adult age.     

Sexual imprinting on facial traits of opposite-sex parents in humans

Positive sexual imprinting is a process by which individuals use the phenotype of their opposite-sex parent as a template for acquiring mates. Recent studies in humans have concluded that an imprinting-like mechanism influences human mate choice in facial traits. However, some of the previous studies have had methodological problems or flaws which might have invalidated or led to an overgeneralization of the original interpretation of their results. In this study, 70 heterosexual adults were used to test if their partners resembled facially their opposite-sex parent as the sexual imprinting hypothesis predicts. Judges assessed the subjective facial similarity between each participant's partner and their parent. We found that there was no perceived facial similarity between women's partners and their fathers. However, men tended to pair more often with women that were perceived as resembling the men's own mothers. In contrast to previous studies, the quality of the relationship between participants and their parents did not predict the level of facial resemblance between the participant's spouse and their parent.     

Asymmetries in the processing of Arabic digits and number words

Numbers can be represented as Arabic digits ("6") or as number words ("six"). The present study investigated potential processing differences between the two notational formats. In view of the previous finding (e.g., Potter & Faulconer, 1975) that objects are named slower, but semantically categorized faster, than corresponding words, it was investigated whether a similar interaction between stimulus format and task could be obtained with numbers. Experiment 1 established that number words were named faster than corresponding digits, but only if the two notation formats were presented in separate experimental blocks. Experiment 2 contrasted naming with a numerical magnitude judgment task and demonstrated an interaction between notation and task, with slower naming but faster magnitude judgment latencies for digits than for number words. These findings suggest that processing of the two notation formats is asymmetric, with digits gaining rapid access to numerical magnitude representations, but slower access to lexical codes, and the reverse for number words.     

Improving the 'how' and 'what' decisions of elite table tennis players

Training methods in sport usually focus on improving either technical or tactical aspects of performance, ignoring the fact that successful performance requires the athlete to simultaneously decide what movement to perform and how it should be executed. Young elite table tennis players were trained, in a first phase, to improve their forehand and backhand movements and, in a second phase, to make a tactical switch between forehand and backhand movements. Half of the players took part in behavioral training focusing on how to perform the required movements, whereas half received additional video feedback about their technical and tactical performance (decision training). The results indicate that improvements of how decisions (techniques) and what decisions (tactics) can occur as a consequence of combining technical and tactical training. These results were stable in delayed Post-test analyses of competitive matches. It was concluded that a combination of both technical and tactical training is beneficial to elite table tennis performers, particularly during early seasonal training programs.     

Does self-consciousness mediate the relation between self-talk and self-knowledge?

Building on Morin's understanding of the relations among self-talk, self-consciousness, and self-knowledge, this study examined the hypothesis that functional and dysfunctional self-consciousness mediate between self-talk and self-knowledge. A self-report questionnaire including 10 scales assessing different aspects of Self-talk, Self-consciousness, and Self-knowledge was administered to 200 German undergraduate university students (95 women, 105 men). Mediation analysis showed that the observed negative relationship between Self-talk and Self-knowledge was mediated by Dysfunctional Self-consciousness, while Functional Self-consciousness acted like a supressor variable. The discussion focuses on limitations of the present measures of Self-talk.
