Erwachsenenschutz bei dementen Patienten aus rechtlicher Sicht

Das 2. Erwachsenenschutz-Gesetz brachte 2017 eine gewisse Neupositionierung in Bezug auf nicht entscheidungsfähige Patienten. Im neuen Recht liegt es wie bisher am Arzt selbst, die Entscheidungsfähigkeit zu beurteilen. Vor Einschalten eines Vertreters greift eine spezielle Unterstützungspflicht (Beiziehung einer Vertrauensperson), um eine Entscheidungsfähigkeit doch noch zu erlangen. Ansonsten erfolgt – abgesehen von Fällen einer Gefahr in Verzug – die Aufklärung gegenüber dem Vertreter des Patienten, der eine allfällige Einwilligung zu erteilen hat. Eine gerichtliche Zustimmung ist grundsätzlich nicht mehr einzuholen.     

Hippocampal Activations during Repetitive Learning and Recall of Geometric Patterns

Hippocampal activation is required for episodic memory. Encoding and retrieval of novel and memorable items have been related to different locations in the hippocampus; however, the data remain ambiguous. The application of a newly designed keyboard allowed investigation of brain activation during encoding and free immediate and delayed recall with functional magnetic resonance imaging (fMRI) in young healthy controls (n=12). Because of the repetitive learning and recall conditions, an individual learning gradient was used to contrast neural activity at different individual levels of novelty. During learning, subjects were asked to memorize 10 geometric patterns requiring the establishment of intra-item associations for memorization. After learning, subjects were asked to recall the items actively via the keyboard. Learning and recall were alternated five times. Delayed recall was scanned about 15 min after the fifth immediate recall condition without subjects having seen the items again. Left-sided anterior hippocampal activity was observed during conditions of initial learning as well as maximum recall. Neural activity during delayed recall did not reveal hippocampal responses and was characterized by a transition of neural activity from occipitoparietal regions to bilateral temporal cortices. We conclude that both lateralization and segregation depend on the specific relational characteristics of the stimuli requiring establishment of intra-item associations for encoding as well as retrieval. The absence of hippocampal activation during delayed recall together with the increase of lateral temporal involvement possibly corresponds with an emerging transition from episodic to long-term memory.     

Rape myths as neutralizing cognitions: evidence for a causal impact of anti-victim attitudes on men's self-reported likelihood of raping

Men's rape myth acceptance (RMA; prejudiced beliefs that serve to exonerate the rapist and blame the victim) has been shown to correlate positively with self-reported rape proclivity (RP). To explore the causal pathway underlying this correlation, two experiments were conducted in which the relative cognitive accessibility of RMA and RP was varied. Male students were asked to report their RP in the context of a scale assessing attraction toward sexual aggression (Experiment 1) or in response to five realistic date-rape scenarios (Experiment 2), either before or after they filled out a 20-item RMA scale. In both studies, the correlation of RMA and RP was significantly greater in the after than in the before condition, suggesting that the belief in rape myths has a causal influence on men's proclivity to rape. © 1998 John Wiley & Sons, Ltd.     

Limitations of Mental Health Case Management: A Rational Emotive and Cognitive Therapy Perspective

Since the closure of many psychiatric hospitals, case management has come to be accepted worldwide as a method of community care for the seriously mentally ill. Although case management has many commendable values, it falls short of providing a comprehensive treatment. It focuses almost exclusively on environmental interventions and largely ignores psychological elements of an individual's functioning. In particular, case management rarely provides clients with evidence-based therapy techniques, such as those developed from a cognitive-behavioral perspective. Consequently, clients with mental illness are not being provided with skills which could help them systematically reduce their emotional disturbance. It is hypothesized that the effectiveness of mental health case management may be enhanced by incorporating evidence-based psychological therapies within a community care model.     

Need for Cognition and the process of lie detection

Four experiments investigated the influence of Need for Cognition on the process of lie detection. According to the basic assumptions of dual process models, only higher Need for Cognition leads to the use of verbal information when making judgments of veracity. People with lower Need for Cognition predominantly use stereotypical nonverbal information for their judgments. In both Experiments 1 and 2, participants saw a film in which nonverbal cues (fidgety vs. calm movements) and verbal cues (low vs. high plausibility) were manipulated. As predicted, when Need for Cognition was lower, only the nonverbal cues influenced participants' judgments of veracity. In contrast, participants with higher Need for Cognition also used the verbal cues. Experiments 3 and 4 tested the hypothesis that higher Need for Cognition leads to better discrimination of truthful from deceptive messages. Both experiments found that participants with higher Need for Cognition achieved higher accuracy at classifying truthful and deceptive messages than participants with lower Need for Cognition.     

An ordinal evaluation of categorical judgement data by random utilities and a corresponding correlation analysis

Categorical judgement data are analyzed along the lines of random utility theory. A class of orders is introduced (categorical weak orders); their characteristic vectors are regarded as points in a Euclidean space; their convex hull forms a polytope whose facets are fully characterized. This polytope is shown to correspond to an order polytope. Furthermore, its relation to the biorder polytope is pointed out. The convex representations of a given point of the polytope are discussed. The impact of these results on the methods of analyzing data arising from a categorical judgement procedure is outlined. In particular, some consequences are drawn with respect to the usual evaluation of correlations of such data.     

Zeitordnung und Zeitpunkte

In many of his writings Russell developed a theory of time,highly interesting bothfrom a philosophical and from a logical point of view.Strangely enough, this has not acquired generalattention. The most important relational propertiesof the duration and points of time will be presented.In addition, Russell's considerations on the existenceand density of time points will becritically analysed and systematically reconstructed.A. G. Walker's explication of the concept of timepoint is unlike that of Russell. His theory oftime reflects the Dedekindian concept of cut.Walker's constructions will be modified in a suitableway and supplemented so that it becomes possileto prove the continuity of the temporal series.
