Das Messie-Syndrom

Messie ist abgeleitet von mess (englisch für Chaos, Unordnung). Betroffene, die als Messies bezeichnet werden, leiden darunter insbesondere im privaten Bereich keine zeitliche und / oder r?umliche Ordnung herstellen oder halten zu k?nnen. Eine eindeutige diagnostische Zuordnung ist bis jetzt nicht m?glich. Je nach Auspr?gungsgrad und Leidensdruck kommen verschiedene therapeutische Ma?nahmen zur Anwendung: Hilfestellung, Coaching, Selbsthilfegruppen, Psychotherapie (kognitive Verhaltenstherapie) und medikament?se Therapie (selektive Serotonin-Wiederaufnahmehemmer).     

Mediators of the relationship between childhood sexual abuse and suicidal behavior in borderline personality disorder

A history of childhood sexual abuse (CSA) increases the risk of suicidal behavior and the lifetime number of suicide attempts in adults with BPD. Despite a strong association, specific variables mediating the relationship between CSA and adult suicidal behavior in BPD have not been identified. This study examined risk factors for suicidal behavior as potential mediators of the relationship between CSA and suicide attempts in 151 men and women with BPD. Diagnostic, clinical, and psychosocial risk factors, as well as CSA, and suicidal behaviors, were assessed by standardized interviews or self-rated measures. Psychotic and schizotypal symptoms, and poor social adjustment, were associated with both CSA and suicidal behavior, and partially mediated the relationship between CSA and attempter status. Psychotic and schizotypal symptoms in BPD define a vulnerability to cognitive and perceptual distortions under stress. They increase the likelihood of suicidal behavior in BPD, especially in the absence of mitigating social support. A theoretical model for suicidal behavior in BPD is presented which integrates direct, mediated, and moderated pathways between childhood sexual abuse and temperament, adolescent and adult risk factors, and suicidal behavior.     

Visual categorization of natural stimuli by domestic dogs

One of the fundamental issues in the study of animal cognition concerns categorization. Although domestic dogs (Canis familiaris) are on the brink to become one of the model animals in animal psychology, their categorization abilities are unknown. This is probably largely due to the absence of an adequate method for testing dogs’ ability to discriminate between large sets of pictures in the absence of human cueing. Here we present a computer-automated touch-screen testing procedure, which enabled us to test visual discrimination in dogs while social cueing was ruled out. Using a simultaneous discrimination procedure, we first trained dogs (N = 4) to differentiate between a set of dog pictures (N = 40) and an equally large set of landscape pictures. All subjects learned to discriminate between the two sets and showed successful transfer to novel pictures. Interestingly, presentation of pictures providing contradictive information (novel dog pictures mounted on familiar landscape pictures) did not disrupt performance, which suggests that the dogs made use of a category-based response rule with classification being coupled to category-relevant features (of the dog) rather than to item-specific features (of the background). We conclude that dogs are able to classify photographs of natural stimuli by means of a perceptual response rule using a newly established touch-screen procedure.

A Bayesian Approach to Informal Argument Fallacies

We examine in detail three classic reasoning fallacies, that is, supposedly ``incorrect' forms of argument. These are the so-called argumentam ad ignorantiam, the circular argument or petitio principii, and the slippery slope argument. In each case, the argument type is shown to match structurally arguments which are widely accepted. This suggests that it is not the form of the arguments as such that is problematic but rather something about the content of those examples with which they are typically justified. This leads to a Bayesian reanalysis of these classic argument forms and a reformulation of the conditions under which they do or do not constitute legitimate forms of argumentation.     

Comparing switch costs: alternating runs and explicit cuing

The task-switching literature routinely conflates different operational definitions of switch cost, its predominant behavioral measure. This article is an attempt to draw attention to differences between the two most common definitions, alternating-runs switch cost (ARS) and explicit-cuing switch cost (ECS). ARS appears to include both the costs of switching tasks and the switch-independent costs specific to the first trial of a run, with the implication that it should generally be larger than ECS, but worse is that the alternating-runs procedure does not allow these costs to be separated. New data are presented to make these issues concrete, existing data are surveyed for evidence that ARS is larger than ECS, and implications of conflating these measures are examined for existing theoretical constructs.     

Assessment of risk for substance use disorder consequent to consumption of illegal drugs: psychometric validation of the neurobehavior disinhibition trait.

Previous research has shown that the trait neurobehavior disinhibition (ND), which consists of affect, behavior, and cognitive indicators of self-regulation, is a significant predictor of substance use disorder (SUD) between childhood and young adulthood. The authors evaluated the psychometric properties of the ND trait in 278 boys evaluated at ages 10-12 and 16 years. ND score significantly predicted SUD and outcomes that commonly manifest in tandem with SUD by age 19, such as violence, arrests, committing crime while intoxicated, and concussion injury. In addition to predictive validity, the ND trait was found to have good construct, discriminative, and concurrent validity, as well as good test-retest and internal reliability. The ND trait may be useful for detecting youths at high risk for developing SUD and related outcomes.     

Comparison of treatment seeking compulsive buyers in Germany and the United States

OBJECTIVE: The aim of this pilot study was to compare a German (Bavaria) and an American (North Dakota) sample of women suffering from compulsive buying. METHOD: Thirty-eight German and 39 American female compulsive buyers were screened with the Compulsive Buying Scale (CBS), and the Yale-Brown Obsessive Compulsive Scale-Shopping Version (Y-BOCS-SV) prior to entering a group treatment study. Psychiatric co-morbidity was assessed with the Structured Clinical Interview for DSM-IV Axis I disorders (SCID). RESULTS: There were no statistically significant differences between the German sample and the American sample with regard to age (mean 43.7 and 45 years, respectively), and with regard to the scores on the CBS and the Y-BOCS-SV. A high lifetime co-morbidity rate with Axis I disorders, especially mood disorders, anxiety disorders, substance use disorders, OCD, and binge eating disorder was detected in both samples. Almost all participants met criteria for at least one lifetime Axis I disorder. However, German compulsive buyers showed significantly higher current prevalence rates of any affective disorder, and higher current and lifetime prevalence rates of any anxiety disorder and somatoform disorder. In addition, German compulsive buyers were significantly more likely to have more than one Axis I disorder. CONCLUSION: The groups did not differ with regard to age and with regard to the severity of compulsive buying and showed a high co-morbidity with Axis I disorders. However, the German compulsive buying sample presented with significantly more psychiatric co-morbidity compared to the American sample. Further research is needed to provide a better understanding of this disorder in general and cross-culturally.     

Children do show negative priming: further evidence for early development of an intact selective control mechanism

Reactions to stimuli that were shortly before presented as distractors are usually slowed down; this phenomenon is known as negative priming. Negative priming is an accepted index for tapping into selective control mechanisms. Although this effect is well established for adults, it has been claimed that children do not show negative priming. Recently, however, V. E. Pritchard and E. Neumann challenged this view and concluded that selective control mechanisms are already fully developed in young children. The authors of the present study analyzed differences between older studies, in which no negative priming had been observed, and the Pritchard and Neumann (2004) study. In sum, the present study yielded further evidence for an intact selective control mechanism in young children. The authors also linked this empirical finding to the broader literature on negative priming by a direct comparison with an adult sample.     

Infant observation: A range of questions and challenges for contemporary psychoanalysis1

The author attempts to integrate several perspectives within the field of infant observation that reflect the analyst's personal experience as a clinician, as a professor at the analytic institute and as a researcher in the field of psychoanalysis. Can infant observation contribute to analytic technique, theory and training? If so, what would be the nature of such contribution? To answer these questions, the author reviews the literature on infant observation from Freud to the present, highlighting Latin American contributions to this subject. She makes reference to the role of technological innovations, which have allowed videotaping, repeated observations, temporal segmentation and computerized programs, thus giving rise to microanalytic research. This discussion prompts the question about the contributions made by systematic research to clinical practice. To tackle this question, the author presents both a clinical vignette taken from her personal experience, and the current debate on this subject as it appears in the work of Daniel Stern and André Green. Finally, she presents some conclusions that are part of an ongoing debate in the psychoanalytic field.
