Confirmation and reduction: a Bayesian account

Various scientific theories stand in a reductive relation to each other. In a recent article, we have argued that a generalized version of the Nagel-Schaffner model (GNS) is the right account of this relation. In this article, we present a Bayesian analysis of how GNS impacts on confirmation. We formalize the relation between the reducing and the reduced theory before and after the reduction using Bayesian networks, and thereby show that, post-reduction, the two theories are confirmatory of each other. We then ask when a purported reduction should be accepted on epistemic grounds. To do so, we compare the prior and posterior probabilities of the conjunction of both theories before and after the reduction and ask how well each is confirmed by the available evidence.     

Übertragung und Übertragungsneurose

The authors investigate Freud's concepts of transference, transference neurosis and their mutual relationship. They discuss the current criticism made on the concept of transference neurosis and raise the question, why patients accept the analyst's interpretations? They suggest understanding transference neurosis as conscious manifestations of transference referring to the analyst which are the outcome of successive interpretations of the type "just-like" followed, changed, and removed again by "just-like-it-was"-interpretations. They conclude that the patient does accept these interpretations not for reasons that are rational, but for reasons pertaining the transference situation.     

Stationäre oder teilstationäre Psychotherapie?

In a pilot study we compared two groups, one of inpatients and one of day clinic patients who were treated between January 1999 and December 2001 at the Department of Psychosomatics and Psychotherapeutic Medicine in Freiburg/Germany. Both settings offer a similar, multimodal and intensive psychotherapy program on a psychodynamic background. In a first explorative data analysis (sociodemographic data, SCL-90-R, IIP-C) we studied differences in severity of initial symptomatology and differences in outcome (prae/post). Patients with anorexia nervosa and a very low weight were preferentially treated in the inpatient setting. In addition the inpatient group of patients with a somatoform disorder showed higher degrees of somatization, as compared to patients with a somatoform disorder in the day clinic. Therapeutic change with respect to psychopathology however did not differ between the two settings: both groups showed a significant improvement during the course of therapy.
