Dissoziative Störungen (Konversionsstörungen)

The ICD-10 diagnostic category of dissociative disorders encompasses very different clinical pictures. The so called dissociative disorders of consciousness are characterized by functional disturbances to the psychic domains of consciousness, identity, autobiographic memory and experience of self and the world. The core features of conversion disorders are functional alterations in the sensorimotor systems. The phenomenological heterogeneity is reflected by prevalence rates ranging from very rare to 30% in clinical populations. Traumatic experiences play a crucial role in the etiology and pathogenesis of these disorders. High rates of comorbid disorders, a tendency to a chronic course and a somatic illness concept in patients with conversion disorders complicate the psychotherapeutic approach. Depending on the therapeutic goals, both psychodynamic and cognitive-behavioral treatment forms are suitable.     

GROUP-LEVEL COPING AS A MODERATOR BETWEEN HETEROSEXISM AND SEXISM AND PSYCHOLOGICAL DISTRESS IN SEXUAL MINORITY WOMEN

The purpose of this study was: (1) to examine concurrently the relationship between heterosexist events and sexist events and psychological distress and (2) to investigate sexual orientation–based and gender-based group-level coping as potential moderators of the heterosexism–distress and sexism–distress links among 282 lesbian and bisexual women. Findings from the Internet survey revealed that, when examined together, both heterosexism and sexism were unique and additive predictors of psychological distress. Results also supported a moderating role of feminist group-level coping in the link between number of sexist events and psychological distress, with the difference between the high– and low–feminist-activity groups occurring at the lower levels of sexism. Thus, it appears that high involvement in feminist activities may provide a buffer against the negative effects of sexism, but only when sexist events are relatively low in number.     

Testimony and Assertion

Two models of assertion are described and their epistemological implications considered. The assurance model draws a parallel between the ethical norms surrounding promising and the epistemic norms which facilitate the transmission of testimonial knowledge. This model is rejected in favour of the view that assertion transmits knowledge by expressing belief. I go on to compare the epistemology of testimony with the epistemology of memory.     

Effects of reduced contrast on the perception and control of speed when driving

Misperception of speed under low-contrast conditions has been identified as a possible contributor to motor vehicle crashes in fog. To test this hypothesis, we investigated the effects of reduced contrast on drivers' perception and control of speed while driving under real-world conditions. Fourteen participants drove around a 2.85 km closed road course under three visual conditions: clear view and with two levels of reduced contrast created by diffusing filters on the windscreen and side windows. Three dependent measures were obtained, without view of the speedometer, on separate laps around the road course: verbal estimates of speed; adjustment of speed to instructed levels (25 to 70 km h(-1)); and estimation of minimum stopping distance. The results showed that drivers traveled more slowly under low-contrast conditions. Reduced contrast had little or no effect on either verbal judgments of speed or estimates of minimum stopping distance. Speed adjustments were significantly slower under low-contrast than clear conditions, indicating that, contrary to studies of object motion, drivers perceived themselves to be traveling faster under conditions of reduced contrast. Under real-world driving conditions, drivers' ability to perceive and control their speed was not adversely affected by large variations in the contrast of their surroundings. These findings suggest that perceptions of self-motion and object motion involve neural processes that are differentially affected by variations in stimulus contrast as encountered in fog.     

Psychologische Mess- und Testverfahren

The use of psychological assessment methods is flawed by incorrect assumptions of their capacity. Some of these assumptions are discussed. It is argued that psychological tests are necessary to expand the database for expert reports about the impact of mental disorders on work and different levels of functioning. Tests help to protect psychological assessments against errors and chance bias. With respect to levels of functioning, examples of German tests and questionnaires are given. Test-based information requires objective validation methods and should not be subordinated to an intuitive assessment strategy.     

Die Sachverständigenexpertise im Spannungsfeld zwischen Justiz und Psychiatrie am Beispiel des Hangbegriffes des § 66 StGB (Sicherungsverwahrung)

Using the example of psychiatric expert opinions in trials leading to preventive detention, we analysed how far the corresponding orders by the courts were suited to guide the psychiatric experts and restrict them to their area of expertise. Furthermore we concentrated on the question, what reasons were given for preventive detention on both psychiatric and judicial side and how psychiatric arguments were adopted by the judges. Our results show clearly, that placing an order with the psychiatric expert as well as adopting the psychiatric arguments for preventive detention occur mainly in a stereotypic way. Psychiatric and judicial arguments for preventive detention refer both to previous delinquency. Aspects concerning the offenders personality appear to be secondary, although they play a major role in the decision for preventive detention. The article shows the controversy associated with forensic-psychiatric expertise in the courtroom and the need for communication and clarification between psychiatry and law.     

Children’s ADHD Symptoms and Friendship Patterns across a School Year

Symptoms of attention-deficit/hyperactivity disorder (ADHD) in elementary school-age children are associated with poor relationships with classroom peers, as indicated by poor social preference, low peer support, and peer victimization. Less is known about how friendship patterns relate to ADHD symptoms, or how friendships may buffer risk for negative peer experiences. Participants were 558 children in 34 classrooms (grades K-5). At the beginning (fall) and end (spring) of an academic year, children completed (a) sociometric interviews to index friendship patterns and social preference, and (b) self-report questionnaires about their support and victimization experiences from classmates. In fall, higher teacher-reported ADHD symptoms were associated with children having more classmates with no friendship ties (non-friends) and who the child nominated but did not receive a nomination in return (unreciprocated friends), and with having fewer classmates with mutual friendship ties (reciprocated friends) and who nominated the child but the child did not nominate in return (unchosen friends). Higher fall ADHD symptoms predicted more non-friend classmates, poorer social preference, and more victimization in the spring, after accounting for the same variables in fall. However, having many reciprocated friends (and to a lesser extent, many unchosen friends) in fall buffered against the trajectory between fall ADHD symptoms and poor peer functioning in spring. By contrast, having many unreciprocated friends in fall exacerbated the trajectory between fall ADHD symptoms and poor peer functioning in spring. Thus, elevated ADHD symptoms are associated with poorer friendship patterns, but reciprocated friendship may protect against negative classroom peer experiences over time.
