Ambulante psychotherapeutische Versorgung depressiver Patienten

Background

The effectiveness of psychotherapeutic interventions in treating depressive disorders has been shown in manifold ways. However, information is missing from the point of view of psychotherapists concerning diagnostic and therapeutic procedures, their experienced difficulties and barriers, their self-assessment of their competence in the handling of depressive patients and the satisfaction with the cooperation in routine care.

Method

A cross-sectional survey of cognitive-behavioral (n=61) and psychodynamic psychotherapists (n=78) was carried out.

Results

The concordance of clinical diagnoses with diagnoses using the formal ICD-10 criteria was very low. Both groups feel themselves specifically responsible for early detection and differential diagnosis. They neither differ with regard to the frequency of cooperation contacts to other service providers nor with regard to their satisfaction with them or the experienced barriers in the care for depressed patients.

Conclusion

A good psychotherapeutic care exists with options for improvement concerning diagnostic procedures and a stronger connection network.     

Identifying decision strategies: A process- and outcome-based classification method

This article presents a classification method that makes possible the detection of important decision strategies that people use in nonrisky multiattribute decision tasks. The classification method incorporates a multimethod approach that combines elements of both structural modeling and process tracing. We begin with a discussion of nine common characteristics of decision strategies and then classify 13 decision strategies on the basis of these characteristics. Next, we demonstrate that six of the characteristics can be used to develop one outcome-based and three process-based metrics. In addition, we present an algorithm that shows how to use the metrics. We demonstrate that using our metrics in conjunction with a measure for direction of search allows identification of most of the 13 decision strategies. Finally, we outline the potential of our research for the design of decision support systems such as online shops.     

Judgment and action knowledge in speed adjustment tasks: experiments in a virtual environment

Two experiments were conducted to investigate children's and adults’ knowledge of time and speed in action and judgment tasks. Participants had to set the speed of a moving car to a new speed so that it would reach a target line at the same time as a reference car moving at a higher speed and disappearing in a tunnel at the midway point. In Experiment 1 (24 10‐year‐olds, 24 adults), children's and adults’ speed adjustments followed the normative pattern when responses had to be graded linearly as a function of the car's initial speed. In a non‐linear condition, only adults’ action responses corresponded with the normative function. Simplifying the task by shortening the tunnel systematically in Experiment 2 (24 10‐year‐olds, 24 adults) enabled children to grade the speeds adequately in the action conditions only. Adults now produced normative response patterns in both judgment and action. Whether people show linearization biases was thus shown to depend on the interaction of age, task demands and response mode.     

The origins of word learning: Brain responses of 3‐month‐olds indicate their rapid association of objects and words

The present study explored the origins of word learning in early infancy. Using event‐related potentials (ERP) we monitored the brain activity of 3‐month‐old infants when they were repeatedly exposed to several initially novel words paired consistently with each the same initially novel objects or inconsistently with different objects. Our results provide strong evidence that these young infants extract statistic regularities in the distribution of the co‐occurrences of objects and words extremely quickly. The data suggest that this ability is based on the rapid formation of associations between the neural representations of objects and words, but that the new associations are not retained in long‐term memory until the next day. The type of brain response moreover indicates that, unlike in older infants, in 3‐month‐olds a semantic processing stage is not involved. Their ability to combine words with meaningful information is caused by a primary learning mechanism that enables the formation of proto‐words and acts as a precursor for the acquisition of genuine words.     

Hypnoanalyse – Ein Stiefkind der Psychoanalyse

Goal of this article is to present the manifold methods and techniques of modern hypnotherapy/hypnoanalysis and to show the possibilities for linking them to traditional psychoanalytical methods. In the introduction, clarification of concepts and a short historical overview is given. The phenomenology of the hypnotical state and its assessment from a psychoanalytical and a non-psychoanalytical view either follows. In this connection the topic of meditation is shortly discussed. In the main part a definition of hypnoanalysis is given, the most important hypnoanalytical methods are described and demonstrated by case studies. The question whether psychoanalysis is to be considered as a trance therapy, is also discussed. Free association in hypnotical trance is especially recommended with patients having difficulties to reach their own feelings.     

Viewpoint dependency in the recognition of dynamic scenes

In 3 experiments, the question of viewpoint dependency in mental representations of dynamic scenes was addressed. Participants viewed film clips of soccer episodes from 1 or 2 viewpoints; they were then required to discriminate between video stills of the original episode and distractors. Recognition performance was measured in terms of accuracy and speed. The degree of viewpoint deviation between the initial presentation and the test stimuli was varied, as was both the point of time presented by the video stills and participants' soccer expertise. Findings suggest that viewers develop a viewpoint-dependent mental representation similar to the spatial characteristics of the original episode presentation, even if the presentation was spatially inhomogeneous.     

Do film cuts facilitate the perceptual and cognitive organization of activitiy sequences?

Film depictions of activities possess two kinds of structures--namely, the structural features of the depicted activities themselves and a formal structure defined by film cuts. The former structure is used by everyday observers for perceptually and cognitively unitizing the continuous flow of events into comprehensible entities. It seems conceivable that cuts can serve a similar unitizing purpose for film viewers. For each of two different activity sequences, two film versions were produced. Throughout each film version, cuts were placed either at breakpoints or at nonbreakpoints. In a 2 x 2 (activity sequence x film version) factorial design, 40 subjects segmented the film during viewing and recalled the film content after viewing in a detailed protocol. Segmentation behavior depended primarily on the occurrence of breakpoints and was largely unaffected by the occurrence of cuts. Cuts accompanying a breakpoint lead to more detailed recall protocols for these sections of the film.     

An evaluation of exact methods for the multiple subset maximum cardinality selection problem

The maximum cardinality subset selection problem requires finding the largest possible subset from a set of objects, such that one or more conditions are satisfied. An important extension of this problem is to extract multiple subsets, where the addition of one more object to a larger subset would always be preferred to increases in the size of one or more smaller subsets. We refer to this as the multiple subset maximum cardinality selection problem (MSMCSP). A recently published branch‐and‐bound algorithm solves the MSMCSP as a partitioning problem. Unfortunately, the computational requirement associated with the algorithm is often enormous, thus rendering the method infeasible from a practical standpoint. In this paper, we present an alternative approach that successively solves a series of binary integer linear programs to obtain a globally optimal solution to the MSMCSP. Computational comparisons of the methods using published similarity data for 45 food items reveal that the proposed sequential method is computationally far more efficient than the branch‐and‐bound approach.
