Ginkgo biloba and memory for a maze.

A number of sources suggest that the natural herb ginkgo biloba enhances mental sharpness by increasing blood flow to the brain. A preliminary study was designed to examine whether memory for a maze would be enhanced in 5 mice who received a dietary supplement containing ginkgo biloba. The mice showed an improved memory for the maze as evidenced by a decrease in the number of errors in reaching the goal box when they received gingko biloba as a dietary supplement.     

Pending intentions: Effects of prospective task encoding on the performance of another task

A number of recent studies casts doubt on the empirical separability of processes of task preparation from the actual execution of the respective task. We report two experiments in which we separated the precueing of a task from its execution by an intervening task. In addition, for the precued task we employed imperative stimuli that in most cases were associated with a competing task, making the execution of this task dependent on an internal representation of the information provided by the precue. Under these conditions, the performance of the intervening task suffered specific interference as a function of its relation to the precued task. This suggests that the encoding of the precue resulted in specific preparation for the precued task. Furthermore, the transition between the intervening task and the precued task was associated with relatively small costs that did not vary as a function of the interval that separated the two tasks. This also suggests that a great deal of preparation for the second task already took place during the encoding of the precue. Further observations suggest that the resolution of the interference between a memory-based task representation, as well as a perceptually induced task representation, and the representation of the currently relevant task took place on the level of individual task features.     

Qualifizierung und Qualitätskontrolle in der forensischen Psychiatrie – die aktuelle Situation in der Schweiz

The practice of civil expert opinions in Switzerland is in a period of upheaval due to fundamental alterations regarding the legal foundations which were implemented on 1 January 2013. The new civil code displaces the authority to order measures which restrict people’s liberty based on an endangerment to themselves or third parties from a lay institution to a newly created expert committee. Moreover, patient’s rights are greatly enhanced. The subsequent consequences for expert opinion activities are not yet appraisable. The development in the practice of insurance legal expert opinion is influenced by new legal measures which aim at reducing the growing number of new disability retirements most notably due to psychiatric disorders. In contrast to the civil area there are already clearly defined standards for the insurance legal area which were established by the Swiss Society of Psychiatry and Psychotherapy in 2012. The legal foundations as well as the practice of expert opinions in the context of the Swiss civil and insurance law are comparable with the German situation but there are still some important differences related to the content and terminology. This paper outlines the current situation and recent developments in Switzerland as well as pointing out differences in comparison to Germany.     

Diagnostik der Hypochondrie

In the current review the criteria for the diagnosis of hypochondriasis in the fourth edition of the Diagnostic and Statistical Manual (DSM-IV) are compared with the criteria for illness anxiety disorder in DSM-5 and differences are discussed. A current review of instruments for the dimensional assessment of the severity of hypochondriasis and associated characteristics (illness-related cognitions and safety behavior) is given. Possible ways of implementing these instruments for planning and evaluating therapy are specified. Furthermore, economical screening methods, which could be broadly applied in medical contexts to identify patients with pronounced illness anxiety in order to offer effective treatment are described and discussed. This procedure would not only lead to a reduction of strain in the person concerned, it would also be connected with financial relief for the health care system.     

Aktuelle Entwicklungslinien in der Pers?nlichkeitsforschung im Jugendalter

Personality disorders in juveniles are still a controversially discussed topic. The aim of this paper is to describe the recent trend in personality research in adolescence and to outline perspectives in research and assessment. Recent study results have pointed out that personality disorders in juveniles can be reliably assessed with diagnostic instruments that have been developed for adults. At the same time there is a lack of specific instruments that can represent the characteristics during adolescence and that can differentiate personality disorders from youth crises. As some personality disorder dimensions also describe unstable developmental criteria we will focus separately on this differential diagnosis and meaning of stable versus transient personality characteristics in youth. The prevalence of personality disorders seems to be higher in adolescence than in adulthood. The stability, however, is comparable in adolescence and adulthood. Psychopathy as a subtype of the antisocial personality disorder ?C that can also be assessed in juveniles ?C will be discussed regarding its core and behavioral dimensions as well as primary and secondary subtypes. Furthermore, we discuss forensic issues when assessing personality disorders with respect to criminal responsibility. Overall we can show that more diagnostic longitudinal studies are essential in order to clarify under which conditions personality disorders develop, which factors influence its course and which interventions can change them.
