Relationship Characteristics and Risk of HIV Infection: Rusbult's Investment Model and Sexual Risk Behavior of Gay Men in Steady Relationships1

This study examined the effects of relationship characteristics, as measured by Rusbult's (1980) investment model, on safer‐sex behavior between steady gay male partners. Analyses showed that low satisfaction with the relationship was associated with more risky unprotected anal intercourse (UAI). High commitment to the relationship was associated with more practice of negotiated safety (i.e., having safe UAI after both partners have tested negative for HIV and have reached sexual safety agreements). High relationship investment was associated with more risky UAI (borderline significant). We conclude that using relationship satisfaction, commitment, and investment as co‐determinants of sexual risk behavior could prove useful in the development of new HIV‐prevention strategies for gay men in relationships.     

From Homeostatic to Hedonic Theories of Eating: Self-Regulatory Failure in Food-Rich Environments

Psychological theories of weight regulation are based on homeostatic feedback assumptions. They mostly attribute the cause of overweight and obesity to lowered sensitivity to internal hunger and satiety cues. Based on the assumption that human food consumption in food-rich environments is increasingly driven by pleasure rather than need for calories, a goal conflict theory of hedonic eating is presented. This theory is not only supported by the outcome of our own research programme but can also account for findings of the research conducted in the context of other psychological theories. Some implications for weight loss strategies are discussed.
Les théories psychologiques sur la régulation du poids sont basées sur des hypothèses d'une rétroaction homéostasique. Elles attribuent généralement la cause de la surcharge pondérale et de l'obésitéà une sensibilité interne amoindrie à la faim et aux indicateurs de satiété. Reposant sur l'hypothèse que la consommation alimentaire humaine dans des environnements riches en nourriture est de plus en plus guidée par le plaisir plutôt que par le besoin de calories, une théorie "goal conflict theory of hedonic eating" est présentée. Cette théorie qui ne s'appuie pas seulement sur les résultats de notre propre programme de recherches, peut aussi expliquer les résultats d'études réalisées dans le cadre d'autres théories psychologiques. Des implications concernant des stratégies de perte de poids sont discutées.     

Functional topography of early periventricular brain lesions in relation to cytoarchitectonic probabilistic maps

Early periventricular brain lesions can not only cause cerebral palsy, but can also induce a reorganization of language. Here, we asked whether these different functional consequences can be attributed to topographically distinct portions of the periventricular white matter damage. Eight patients with pre- and perinatally acquired left-sided periventricular brain lesions underwent focal transcranial magnetic stimulation to assess the integrity of cortico-spinal hand motor projections, and functional MRI to determine the hemispheric organization of language production. MRI lesion-symptom mapping revealed that two distinct portions of the periventricular lesions were critically involved in the disruption of cortico-spinal hand motor projections on the one hand and in the induction of language reorganization into the contra-lesional right hemisphere on the other hand. Both regions are located in a position compatible with the course of cortico-spinal/cortico-nuclear projections of the primary motor cortex in the periventricular white matter, as determined by the stereotaxic probabilistic cytoarchitectonic atlas developed by the Jülich group.     

Delinquenzverläufe jugendlicher Sexualmörder

Sexual homicides by juvenile offenders are statistically rare and until now only a few studies explored this phenomenon. Studies on forensic psychiatric court reports and follow-up data from federal criminal records were used to investigate the delinquency of a sample of 19 juvenile sexual homicide perpetrators from their childhood up to the mean age of 45 years of age. More than the half (58%) committed or attempted sexual assaults prior to the sexual homicide. Seven from 13 who were released from custody (54%) committed sexual or violent reoffences. In a long-time analysis as much favourable as unfavourable developments were found. The results suggest that most of the persons who commit sexual homicides as juveniles already committed sexual offences before and have a high risk of sexual and violent reoffending even a long time after the homicide.     

The allure of forbidden food: On the role of attention in self-regulation

The aim of the present studies was to examine the impact of food cues on restrained eaters’ attention for food. Previous research has shown that restrained eaters spontaneously activate hedonic thoughts in response to palatable food cues, and that such food cues also lead them to inhibit their dieting goal. We argue that as a consequence, restrained eaters’ selective attention will automatically be drawn towards hedonically relevant food items. Consistent with our expectations, the results of two studies revealed that restrained eaters, but not unrestrained eaters, displayed an attentional bias for hedonically rated food items when they had been pre-exposed to food cues. However, this attentional bias did not occur when restrained eaters were primed with the concept of dieting, thereby rendering the regulation of eating behavior more successful. These findings are discussed in the context of implicit processes in self-regulation.     

A social functional approach to emotions in bargaining: when communicating anger pays and when it backfires

Previous research on the communication of emotions has suggested that bargainers obtain higher outcomes if they communicate anger than if they communicate happiness because anger signals higher limits, which in turn leads opponents to give in. Building on a social functional account of communicated emotions, the authors demonstrate that the behavioral consequences of communicated anger strongly depend on structural characteristics of the bargaining situation. The results of 3 experimental studies on ultimatum bargaining corroborate the notion that communicated anger signals higher limits and that emotion effects are contingent on bargainers' expectation that low offers will be rejected. The data also indicate, however, that communicating anger in bargaining may backfire. The findings suggest that bargainers who communicate anger may obtain lower outcomes (a) when their opponent has a possibility to deceive them during bargaining and (b) when the consequences of rejecting their opponent's offer are low. Taken together, the current article reveals the boundary conditions of successful communication of anger in bargaining.     

Husserl and Haugeland on Constitution

Both Husserl and Haugeland develop an account ofconstitution to address the question of howour mental episodes can beabout physical objects and thus, through the intentionalrelation, bridge the gap betweenthe mental and the physical. The respectivetheories of the two philosophers of very differentbackground show not only how mentalepisodes can have empirical content, but also howthis content is shaped by pastexperiences or a holistic background of other mentalepisodes. In this article I first outlineand then contrast their positions in order to showhow the notion of constitution can beadopted to address major problems of contemporaryphilosophy of mind, especially thequestion of how the mind can be related to itsphysical environment.     

The presence of the past: using memory work to search for psychological traces of the Nazi past in contemporary Germans

This study examines how far traces of the Nazi past can still be found in the psychological family environment of college students and academics attending a counselling centre two generations after the end of World War II. It considers how such traces can be elicited in discussions and tackled systematically within a therapeutic context. It was found that many families had never talked about their memories of the Nazi period, ignoring or repressing them. This study showed that the failure to discuss such topics within families was of decisive significance during counselling sessions, and that current problems often relate to an unprocessed family past.     

Sozialmedizinische Begutachtung der beruflichen Leistungsfähigkeit

The ?Interview for the Evaluation of Psychosocial Dimensions of Performance Capability“ represents a potentially suitable instrument for the assessment of performance capability in various contexts. Regarding time expenditure, it is very viable and can be applied without special training. Test statistics for subscales derived from factor analysis are satisfying. The modified scales should be subject to further studies of validity and reliability. However, the instrument is already suited as a tool for the assessment of performance capability, represents an algorithm for decision-making and is related to the concepts of the International Classification of Functioning (ICF).
