Special online consulting for patients with eating disorders and their relatives: analysis of user characteristics and E-mail content.

In the treatment of chronic diseases, programs that use the internet as a medium are becoming more and more important as a complement to classical intervention techniques. Since 1998, a non-profit information and online consulting service for patients with eating disorders and their friends and relatives (www.ab-server.de) has existed. This was established by members of the Deutsche Forschungsinitiative Essst?rungen e.V. (DFE) [German Research Initiative for Eating Disorders] and members of the Clinic of Psychiatry, University of Leipzig, Germany. For the present study, 2,176 e-mail requests from users of the online consultation service were analyzed qualitatively and quantitatively in order to better understand the differences between different types and groups of users. The analysis was related to the social field of the person requesting the consultation, the type of disorder reported, and the content of the e-mail request. Three main user groups could be identified: people who described themselves as having an eating disorder (57.2%), people who were related socially to the affected person (32.4%), and interested persons (9.8%). The consulting service was predominantly used by persons suffering from bulimia nervosa or their families and friends (63.1%). One third (33.3%) of the posted e-mails were related to behavioral patterns in dealing with the illness and the affected person. They were followed by inquiries for information about the disease (18.7%) and by those seeking help in finding specialized clinics/therapists and places in therapies. The increasing use of the online consulting service indicates that there is a substantial need for information and help in persons with eating disorders and in their relatives, who are able to easily contact professionals using this online service. Online consulting has a high potential for complementary care of affected people.     

From Speculative Nanoethics to Explorative Philosophy of Nanotechnology

In the wake of the emergence and rapid development of nanoethics there swiftly followed fundamental criticism: nanoethics was said to have become much too involved with speculative developments and was concerning itself too little with actually pending questions of nanotechnology design and applications. If this diagnosis is true, then large parts of nanoethics are misguided. Such fundamental criticism must surely either result in a radical reorientation of nanoethics or be refuted for good reasons. In this paper, I will examine the critics’ central arguments and, building on this scrutiny, formulate an answer to these alternatives. The results lead to conclusions which allow explaining and unfolding the thesis of this paper that instead of speculative nanoethics we should better speak of and develop explorative philosophy of nanotechnology.     

The maintenance of fluency after intensive in-patient therapy: Long-term follow-up

Maintenance of fluency after intensive in-patient treatment was studied in eight male stammerers. Reasons for success and failure are discussed in relation to objective and subjective data collected at the final follow-up interview.     

How Interpersonal Coordination Affects Individual Behavior (and Vice Versa): Experimental Analysis and Adaptive HKB Model of Social Memory

How one behaves after interacting with a friend may not be the same as before the interaction. The present study investigated which spontaneous coordination patterns formed between 2 persons and whether a remnant of the interaction remained (“social memory”). Pairs of people sat face-to-face and continuously flexed index fingers while vision between partners was manipulated to allow or prevent information exchange. Trials consisted of 3 successive 20-s intervals: without vision, with vision, and again without vision. Steady, transient, or absent phase coupling was observed during vision. In support of social memory, participants tended to remain near each other's movement frequency after the interaction ended. Furthermore, the greater the stability of interpersonal coordination, the more similar partners' postinteractional frequencies became. Proposing that social memory resulted from prior frequency adaptation, a model based on Haken–Kelso–Bunz (HKB) oscillators reproduced the experimental findings, even for patterns observed on individual trials. Parametric manipulations revealed multiple routes to social memory through the interplay of adaptation and other model parameters. The experimental results, model, and interpretation motivate potential future research and therapeutic applications.     

Quantifying temporal ventriloquism in audiovisual synchrony perception

The integration of visual and auditory inputs in the human brain works properly only if the components are perceived in close temporal proximity. In the present study, we quantified cross-modal interactions in the human brain for audiovisual stimuli with temporal asynchronies, using a paradigm from rhythm perception. In this method, participants had to align the temporal position of a target in a rhythmic sequence of four markers. In the first experiment, target and markers consisted of a visual flash or an auditory noise burst, and all four combinations of target and marker modalities were tested. In the same-modality conditions, no temporal biases and a high precision of the adjusted temporal position of the target were observed. In the different-modality conditions, we found a systematic temporal bias of 25–30 ms. In the second part of the first and in a second experiment, we tested conditions in which audiovisual markers with different stimulus onset asynchronies (SOAs) between the two components and a visual target were used to quantify temporal ventriloquism. The adjusted target positions varied by up to about 50 ms and depended in a systematic way on the SOA and its proximity to the point of subjective synchrony. These data allowed testing different quantitative models. The most satisfying model, based on work by Maij, Brenner, and Smeets (Journal of Neurophysiology 102, 490–495, 2009), linked temporal ventriloquism and the percept of synchrony and was capable of adequately describing the results from the present study, as well as those of some earlier experiments.     

Internalization of the therapeutic process: differences between borderline and neurotic patients

Intersession process in psychotherapy refers to the thoughts, memories, and feelings about each other and about their therapy sessions that participants experience during the intervals between sessions. This study compared the intersession process experienced by patients who had been diagnosed with severe borderline personality disorders (BPD) with others who had not. A total of 76 patients with neurotic disturbances and 20 patients with BPD were treated in a therapeutic day clinic and completed the Intersession Experience Questionnaire (IEQ) before sessions of individual psychotherapy and the Session Questionnaire (Stundenbogen) after those sessions. Comparison of the two groups on these measures of intersession process and postsession outcome showed markedly different patterns in patients' evaluations and internalizations of in-session therapeutic experiences: most prominently, that BPD patients internalize therapy sessions with much more negative and contradictory emotions.
