Verlorenes Objekt, Trennung und Anerkennung

Zusammenfassung. Die Verarbeitung von Trennungserfahrungen ist für die Psychoanalyse ein zentrales Anliegen. Trennungserfahrungen spielen in verschiedenen analytischen Konzepten eine Rolle. Zun?chst mu? daher gekl?rt werden, welche verschiedenen Dimensionen des Themas „Trennung” in der psychoanalytischen Theorie ausgearbeitet worden sind. Da? Trennungen verarbeitet werden k?nnen, ist an bestimmte Voraussetzungen geknüpft. Die Folgen von Trennungserfahrungen sind v.a. aus einer intrapsychischen Perspektive beschrieben worden. Diese Betrachtungsweise mu? durch eine intersubjektive erg?nzt werden. Klinische Konzepte früher Trennungspathologien und die neuere S?uglingsforschung weisen auf die Bedeutung der intersubjektiven Perspektive für die Psychoanalyse hin. Intrapsychische und intersubjektive Perspektive schlie?en einander nicht aus, sondern verschr?nken sich miteinander. Wesentlich für dieses Wechselspiel ist der Begriff der Anerkennung, der in Anlehnung an Benjamin eingeführt wird. Er ist hilfreich, um die ethischen Implikationen der psychoanalytischen Trennungsmodelle zu bedenken.

The lost object, separation and recognition. About the foundation of psychoanalytic therapy and psychoanalytic ethics concerning the experience of separation

Summary. There exists not only one psychoanalytic concept of ”separation”. Instead, it covers a wide range of psychoanalytic constructs, such as separation in Mahler’s terms, object loss, castration, the Lacanian model of psychic representation and so forth. The first aim of the present paper is to clarify the various concepts. As will be shown, most psychoanalytic concepts focus on the intrapsychic dimension of separation processes. Nevertheless, the working through of separation experiences is bound to intersubjective experiences as can be shown in reference to the clinical concepts on very early interpersonal pathology and to the contemporary research on infantile development. The intersubjective and intrapsychic perspectives do not contradict, but supplement each other. J. Benjamin has introduced the term ”recognition” into the psychoanalytic debate. Recognition is a major link between the two perspectives. It is helpful to outline the ethical consequences that can be drawn from the psychoanalytic concepts on ”separations”.

     

Minimal Belief Change and the Pareto Principle

This paper analyzes the notion of a minimal belief change that incorporates new information. I apply the fundamental decision-theoretic principle of Pareto-optimality to derive a notion of minimal belief change, for two different representations of belief: First, for beliefs represented by a theory – a deductively closed set of sentences or propositions – and second for beliefs represented by an axiomatic base for a theory. Three postulates exactly characterize Pareto-minimal revisions of theories, yielding a weaker set of constraints than the standard AGM postulates. The Levi identity characterizes Pareto-minimal revisions of belief bases: a change of belief base is Pareto-minimal if and only if the change satisfies the Levi identity (for “maxichoice” contraction operators). Thus for belief bases, Pareto-minimality imposes constraints that the AGM postulates do not. The Ramsey test is a well-known way of establishing connections between belief revision postulates and axioms for conditionals (“if p, then q”). Pareto-minimal theory change corresponds exactly to three characteristic axioms of counterfactual systems: a theory revision operator that satisfies the Ramsey test validates these axioms if and only if the revision operator is Pareto-minimal. This revised version was published online in June 2006 with corrections to the Cover Date.     

Stimulus-response compatibility and sequential learning in the serial reaction time task

The serial reaction time (SRT) task is a commonly used paradigm to investigate implicit learning. In most studies the settings originally introduced by Nissen and Bullemer are replicated, i.e., subjects respond to a visuo-spatial sequence of stimulus locations by pressing spatially compatible arranged keys. The present experiment was designed to explore to what degree the sequential learning observed under these conditions depends on the use of locational sequences. Under otherwise identical conditions, first the S-R compatibility was reduced by using symbols instead of locations as stimuli, and second, the connectibility, i.e, the ease of connecting successive stimuli into coherent pattern, was varied. Effects on reaction times (RT) in the SRT task and on explicit memory in a generation task were evaluated. The results indicate that the connectibility of the stimuli has no effect at all and that S-R compatibility influences only the general RT level but does not seem to modify the learning process itself. Thus, the data are more consistent with the notion that learning is based primarily on the sequence of responses rather than on the sequence of stimuli. Moreover, a post hoc classification of subjects with regard to the amount of explicit sequence knowledge they have acquired reveals a striking modification of the general result: The RT difference between responses to locations and symbols vanishes in the course of learning for the complete explicit knowledge group. In order to account for this effect, we presume that the response control of these subjects shifts from stimuli to motor programs, so that RTs become increasingly independent of the stimuli used.     

Smells like sib spirit: kin recognition in three-spined sticklebacks (<Emphasis Type="Italic">Gasterosteus aculeatus</Emphasis>) is mediated by olfactory cues

The ability to recognise kin has been demonstrated in several animal species. However, the mechanisms of kin recognition often remain unknown. The most frequently discussed sensory modalities to recognise kin are visual, olfactory and acoustical cues. Three-spined sticklebacks (Gasterosteus aculeatus) are able to differentiate between kin and non-kin when presented visual and olfactory cues combined. To elucidate, which cues they use to recognise kin female sticklebacks were given the choice between two identical computer animations of courting stickleback males. Next to one animation, water conditioned by a brother was added, while near the other, water from an unrelated male was added. In half of the experiments, the brother was familiar while in the other half he was unfamiliar to the female. Both scenarios were carried out with both outbred and inbred fish. The results showed that the females adjusted their choice behaviour according to relatedness. Furthermore, they were able to recognise both familiar as well as unfamiliar brothers. Inbreeding did not affect this ability. Hence, three-spined sticklebacks are able to recognise their relatives using olfactory cues alone. The cognitive mechanisms underlying this ability were independent from familiarity and not impaired by inbreeding.     

Psychische Beschwerden und Störungen von Studierenden

Background

Psychological distress among students is receiving growing attention in the scientific community as well as in the general public. There are counseling services available in student societies and universities which address psychological distress among students but scientific research in this area is rudimentary and poorly represented.

Problem in question

In order to present the prevalence, extent and type of psychological disorders in students and the alterations over time, an investigation was carried out to show which psychological complaints and disorders were present in students who consulted a psychotherapeutic counseling center. These data were compared with the psychological complaints of a student field study population. Furthermore, alterations in the psychological complaints and disorders of students over periods of 10 and 15 years will be presented.

Methods

The prevalence and change over time of psychological syndromes in students were identified by a comparison between an unselected sample of counseling center clients and several student field samples from the previous 15 years. The type of distress and severity of symptoms were measured with a Symptom Checklist (SCL-90-R), the Psychosocial Complaints List (PSB), the Satisfaction With Life And Studies Scale (LSZ), the diagnostic assessment according to International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10), the Complaints Severity Score (BSS) and Global Assessment of Functioning (GAF).

Results

Previous results of investigations which showed that 20–25% of students suffer from psychological disorders could be confirmed in this study. However, 60–65% of the clients of a counseling center suffered from clinically relevant psychological disorders, which is significantly higher. The most common disorders were depressive moods, lack of self-confidence and exam anxiety, which can mostly be diagnostically assigned to adjustment, depression and anxiety disorders. The comparison with previous studies showed that the types and severity of psychological distress among students have remained stable over the last 15 years, with the exception of test anxiety which increased by 51% from 1993 to 2008. With respect to alcohol abuse, considerably less impairments were found than had been assumed based on the earlier investigations.

Conclusions

Psychological complaints and disorders are frequently found among students and they cause individual suffering as well as economic expenses. Noticeable was the obvious increase in clinically relevant exam anxiety. Psychological-psychotherapeutic counseling centers make an important contribution to screening, clinical assessment, primary health care and prevention of severe mental disorders among students and have shown a continuously increasing number of cases in recent years. Further studies especially in a process-outcome design of the mostly eclectic counseling centers are needed and possibilities will be presented.
