Perceiving subjectivity in bodily movement: The case of dancers

This paper is about one of the puzzles of bodily self-consciousness: can an experience be both and at the same time an experience of one′s physicality and of one′s subjectivity? We will answer this question positively by determining a form of experience where the body′s physicality is experienced in a non-reifying manner. We will consider a form of experience of oneself as bodily which is different from both “prenoetic embodiment” and “pre-reflective bodily consciousness” and rather corresponds to a form of reflective access to subjectivity at the bodily level. In particular, we argue that subjectivity is bodily expressed, thereby allowing the experience of the body′s subjectivity directly during perceptual experiences of the body. We use an interweaving of phenomenological explorations and ethnographical methods which allows validating this proposal by considering the experience of body experts (dancers).     

Psychosomatik der umweltbezogenen Gesundheitsstörungen

Environmental medicine focuses on acute and chronic effects of chemical and physical environmental influences on health as measured objectively and perceived subjectively. Since these influences are very complex, continuously changing and only partially accessible in scientific experiments, subjective causal attributions can be difficult to prove or disprove. Patients with symptoms attributed to environmental triggers perceive health threats from commonly used chemical agents or electromagnetic radiation, frequently without objective findings. Typical examples are “multiple chemical sensitivity (MCS)”, a generalized self-reported hypersensitivity towards ubiquitous chemicals, or “amalgam sensitivity”, where symptoms are attributed to amalgam from dental fillings. Here, the reported symptoms are almost invariably unspecific and show a high overlap with other medically unexplained syndromes. Based on modern psychosomatic conceptualizations, many environment associated illnesses can be regarded as somatoform disorders and treated as such. Apart from a high psychiatric comorbidity, special attention should be paid to dysfunctional cognitions, emotions and behaviour, and the patient’s often limited quality of life.     

Der Arztbrief

The right of inspection in the hospital documents, the hospital discharge report for example, is often refused to patients in in-patient psychotherapeutic treatment (psychiatry, psychosomatic and psychotherapeutic medicine) with reference to the protection of the patients themselves, their doctors or relatives. Within a systemic therapy approach patients of an acute psychosomatic care unit in a hospital the patients could inspect the report of their hospital treatment including all ?objective” and ?subjective” data of their hospital stay. The conversation with patients and their relatives about this report and modifications of the details and addresses of the report in case of patients’ objections is considered as a psychotherapeutic tool (narrative of doctor and patient) in order to improve the transparency of the diagnostic and therapeutic process and the insights in the psychosomatic mechanisms of the patient’s disease. We discuss our organisation of cocreating the hospital discharge report and our experiences with this type of patient-doctor-communication.     

Überlegungen zur theoretischen Fundierung der Disziplin Wirtschaftsinformatik, ausgehend von der allgemeinen Systemtheorie

Using general system theory as a theoretical foundation of business information systems science. The science of business information systems is looking for its theoretical foundations. In this article general system theory is adapted to serve as such a theoretical foundation. The adapted general system theory is reconstructed using the structuralistic approach to reveal the empirical claims of this theory and to analyse scientific progress in the science of business information systems. This revised version was published online in August 2006 with corrections to the Cover Date.

Children's initial sleep‐associated changes in motor skill are unrelated to long‐term skill levels

Sleep is considered to support the formation of skill memory. In juvenile but not adult song birds learning a tutor's song, a stronger initial deterioration of song performance over night‐sleep predicts better song performance in the long run. This and similar observations have stimulated the view of sleep supporting skill formation during development in an unsupervised off‐line learning process that, in the absence of external feedback, can initially also enhance inaccuracies in skill performance. Here we explored whether in children learning a motor sequence task, as in song‐learning juvenile birds, changes across sleep after initial practice predict performance levels achieved in the long run. The task was a serial reaction time task (SRTT) where subjects had to press buttons which were lighted up in a repeating eight‐element sequence as fast as possible. Twenty‐five children (8–12 years) practised the task in the evening before nocturnal sleep which was recorded polysomnographically. Retrieval was tested on the following morning and again 1 week later after daily training on the SRTT. As expected, changes in response speed over the initial night of sleep were negatively correlated with final performance speed after the 1‐week training. However, unlike in song birds, this correlation was driven by the baseline speed level achieved before sleep. Baseline‐corrected changes in speed or variability over the initial sleep period did not predict final performance on the trained SRTT sequence, or on different sequences introduced to assess generalization of the trained behaviour. The lack of correlation between initial sleep‐dependent changes and long‐term performance might reflect that the children were too experienced for the simple SRTT, possibly also favouring ceiling effects in performance. A consistent association found between sleep spindle activity and explicit sequence knowledge alternatively suggests that the expected correlation was masked by explicit memory systems interacting with skill memory formation.     

Positive schizotypal symptoms predict treatment outcome in obsessive-compulsive disorder

Previous research has suggested that the presence of schizotypal personality disorder may represent a risk factor for treatment failure in obsessive-compulsive disorder (OCD). Relying on a dimensional approach, the present study investigated whether the predictive importance of schizotypal personality is shared by all of its features to the same extent or whether it is confined to a subset of symptoms. Fifty-three patients underwent multi-modal cognitive-behavioral therapy with or without adjunctive antidepressive medication. Therapy response was defined as a 35% decline of the Y-BOCS total score. At baseline assessment, patients were asked to fill out the schizotypal personality questionnaire, the perceptual aberration scale and the Beck depression inventory. Stepwise regression analysis and group comparisons conducted with the schizotypal and depression scales revealed that elevated scores in the positive schizotypal scales, especially perceptual aberrations, were highly predictive for treatment failure. Responders to treatment and non-responders did not significantly differ on other variables or on scores in two scales which measured response biases. The study provides evidence that positive schizotypal symptoms are antecendents for treatment failure in OCD. It needs to be evaluated whether these at-risk individuals benefit from additional intervention, such as the adminstration of low-dose atypical neuroleptics and specifically tailored behavorial intervention.     

Aspects of temporal information processing: A dimensional analysis

A major controversy in the field of prospective temporal information processing refers to the question of whether performance in various temporal tasks can be accounted for by the general assumption of an internal clock rather than by distinct, task-specific timing mechanisms. Therefore, the present study was designed to identify dimensions of temporal information processing. For this purpose, 120 subjects performed eight psychophysical temporal tasks. Correlational and principal factor analyses suggested a common pacemaker-based interval timing mechanism involved in duration discrimination, temporal generalization, and temporal order judgment. On the other hand, rhythm perception and perceived simultaneity/successiveness appeared to be controlled by task-specific processes unrelated to interval-based timing.     

Evidence for episodic retrieval of inadequate prime responses in auditory negative priming

Four experiments are reported in which the mechanisms underlying auditory negative priming were investigated. In Experiments 1A and 1B, preprime-prime intervals and prime-probe intervals were manipulated. The ratio between the 2 intervals determined the size of the negative priming effect. Results are compatible with the episodic retrieval account, according to which the retrieval of inappropriate response information associated with the previous distractor slows down responding when that stimulus becomes the target. Experiment 2 tested a variant of this account, according to which the retrieval of the prime response rather than the retrieval of nonresponse information interferes with responding. Consistent with this variant, participants erroneously responded with the prime response more frequently in the ignored repetition condition than in the control condition. Experiment 3 replicated this finding and generalized it to the visual modality. The authors conclude that the retrieval of the inappropriate prime response is a determinant of the negative priming phenomenon.
