Attention capacity and task difficulty in visual search

When a visual search task is very difficult (as when a small feature difference defines the target), even detection of a unique element may be substantially slowed by increases in display set size. This has been attributed to the influence of attentional capacity limits. We examined the influence of attentional capacity limits on three kinds of search task: difficult feature search (with a subtle featural difference), difficult conjunction search, and spatial-configuration search. In all 3 tasks, each trial contained sixteen items, divided into two eight-item sets. The two sets were presented either successively or simultaneously. Comparison of accuracy in successive versus simultaneous presentations revealed that attentional capacity limitations are present only in the case of spatial-configuration search. While the other two types of task were inefficient (as reflected in steep search slopes), no capacity limitations were evident. We conclude that the difficulty of a visual search task affects search efficiency but does not necessarily introduce attentional capacity limits.     

Expectation and repetition effects in searching for featural singletons in very brief displays

We studied the effects of expectation and repetition on searching for singletons in very brief displays. In Experiment 1, we found that when a given feature defined the singleton for a whole block--so that in every trial the subject could expect a particular target feature--search accuracy was significantly higher than when the feature setting was randomly redetermined from trial to trial. However, an unexpected repetition triggered almost no advantage. In Experiment 2, we found no advantage for expected alternation. Experiments 3 and 4 demonstrated that there is little or no advantage for perception in conditions allowing only for target-feature facilitation or distractor-feature inhibition. We propose that in singleton search a division of feature space facilitates detection, and that this division works best under conditions of expected repetition. Experiment 5 replicated Experiment 1, but in Experiment 5 we examined response times and long display exposures. Results suggested that previous findings of singleton priming reflect mainly postperceptual factors.     

Explizite und implizite psychoanalytische Behandlungspraxis

Zusammenfassung  Die Psychoanalyse wurde mit dem Ziel konzipiert, Verdrängungen dem Bewusstsein zugänglich zu machen und dadurch die Kindheitsamnesie aufzuheben (Freud 1937). Mit der Ausweitung des psychoanalytischen Behandlungsspektrums auf präödipale Störungen und Verbreitung der Objektbeziehungstheorie entwickelte sich allerdings eine alternative Behandlungsstrategie, die Therapie der emotionalen Erfahrung. Der damit verknüpfte Dualismus führte lange zu einer Kontroverse über eine einheitliche psychoanalytische Behandlungstechnik. Nur langsam setzte sich die Erkenntnis durch, dass angemessene Deutungen und ein entwicklungsfördernder Umgang mit der Übertragung zwei therapeutische Ansätze darstellen, die nicht voneinander zu trennen sind.Vor dem Hintergrund der neueren Gedächtnisforschung zeigt sich, dass beide Ansätze sich einerseits ergänzen, andererseits aber auch gegensätzliche Pole im Indikationsspektrum der psychoanalytischen Praxis repräsentieren. Die Einsichtstherapie der klassischen Analyse hat das episodische, explizite Gedächtnis als Bezugspunkt und in dieser Weise auch weiterhin Gültigkeit. Demgegenüber bezieht sich die Therapie der emotionalen Erfahrung auf implizites Erfahrungswissen, das den Kern der Patienten mit einer Entwicklungspathologie ausmacht.In dieser Arbeit wird die implizite psychoanalytische Behandlungspraxis im Umgang mit archaischen Ich-Zuständen erläutert. Dabei wird die Bedeutung der bekannten Behandlungskonzepte Objektverwendung, Metabolisierung und containment hervorgehoben.

Explicit and implicit psychoanalytical practice

Psychoanalysis was conceived with the aim of making suppressed experiences available to the consciousness and by means of this, reversing childhood amnesia. In the course of the extension of the psychoanalytical treatment spectrum to pre-oedipal disturbances and the increasing influence of the object relation theory an alternative therapeutic strategy, the therapy of emotional experience, was developed. The related dualism led to a long-lasting controversy about a uniform psychoanalytical technique. The insight that adequate interpretations and beneficial handling of the relationship are two therapeutical approaches which have not to be separated from each other, has been accepted slowly.Against the background of recent memory research it turns out that on the one hand both approaches supplement each other, but on the other hand they are contrasting poles in the indication spectrum of psychoanalytical practice. The therapy of insight of classical psychoanalysis has the explicit memory as a reference point and is therefore still valid. On the contrary, the therapy of emotional experience refers to implicit experience which is the core of developmental pathology.In this paper the implicit psychoanalytical practice, dealing with archaic ego states, is discussed, referring to such well-known concepts as object use, metabolization and containment.

Lebensqualität von ärztlichen und psychologischen Psychotherapeuten

In a large empirical cross-sectional study the quality of life of medical and psychological psychotherapists ( n =71, respectively n =103) was examined as well as the influence of the different therapeutic methods used. Instruments used were the Questionnaire on Quality of Life of Physicians (Reimer and Jurkat 2003) respectively the Questionnaire on Quality of Life of Psychologists (Jurkat and Reimer 2003) as well as the SF-36 Health Survey (Bullinger and Kirchberger 1998). The majority of participants in both samples are satisfied with their life. Psychological psychotherapists are comparatively more content with their work situation and judge their own health more positively than their medical colleagues do. Both groups feel their income situation to be a loss in quality of life. A common fear is an even greater bureaucratic burden and financial deterioration. Thus it seems that psychohygienic measures and secure job perspectives may contribute to raising the quality of life of psychotherapists.     

Tinnitus als soziale Infektion?

Background

11 out of 35 male employees of a central alert team with rescue coordination function developed a tinnitus disorder. This clinical case-study highlights the psychodynamic background of this accumulation.

Methods

Employees were investigated by psychometric questionnaires and semistructured psychodynamic biografical interviews. Additionally aspects of group dynamics and organisational structure were assessed.

Results

All staff members reported adverse work conditions. Medical and psychometric examination of the tinnitus patients did not reveal severe pathological findings. The interviews identified psychodynamic conflicts dealing with autonomy and regulation of self-esteem. All tinnitus patients reported a very adverse or punitive father relation and difficulties in performing a stabile male role and self-image. Group dynamics was dominated by paranoid and regressive tendencies complicated by maladaptive coping, crude perception of external facts and a pronounced experience of aggressive impulses.

Conclusion

The remobilisation of infantile powerlessness, ineffectiveness and helplessness triggered by adverse work conditions and the introduction of a new culture of personal responsibility within the work organisation together with an impaired coping of separation conflicts enforced by traumatic aspects of the relation with the father may have promoted the tinnitus symptomatology. Additionally, due to the missing awareness of the importance of such group dynamical processes the employers contributed to an increasing psychosocial distress, which promoted the accumulated manifestation of tinnitus as a conflict expressive symptom.
