Stationäre Kinder- und Jugendpsychiatrie sowie Psychotherapie bei substanzabhängigen Jungen und Mädchen

This study examines post-treatment outcomes (6 and 12 months post-release) of a multimodal child and adolescent psychiatric and psychotherapeutic inpatient treatment program for boys and girls diagnosed with substance use disorders (n=71) in 2 centres. Up to now there has been a lack of outcome research in this field in Germany. Outcome measures included drug use patterns and psychopathology. The greatest reductions in prevalence at 1 year follow-up occurred for cannabis, methamphetamine, cocaine and heroin use. Additionally the patients and their parents also reported significant improvements in adolescent’s psychopathology at the 1 year follow-up. The results underline the importance of disorder-specific, multimodal inpatient programs for the treatment of children and adolescents with substance use disorders.     

Emotions as metarepresentational states of mind: Naturalizing the belief–desire theory of emotion

Describes the outlines of a computational explication of the belief–desire theory of emotion, a variant of cognitive emotion theory. According to the proposed explication, a core subset of emotions including surprise are nonconceptual products of hardwired mechanisms whose primary function is to subserve the monitoring and updating of the central representational system of humans, the belief–desire system. The posited emotion-producing mechanisms are analogous to sensory transducers; however, instead of sensing the world, they sense the state of the belief–desire system and signal important changes in this system, in particular the fulfillment and frustration of desires and the confirmation and disconfirmation of beliefs. Because emotions represent this information about the state of the representational system in a nonconceptual format, emotions are nonconceptual metarepresentations. It is argued that this theory of emotions provides for a deepened understanding of the role of emotions in cognitive systems and solves several problems of psychological emotion theory.     

Rhythm histograms and musical meter: A corpus study of Malian percussion music

Studies of musical corpora have given empirical grounding to the various features that characterize particular musical styles and genres. Palmer & Krumhansl (1990) found that in Western classical music the likeliest places for a note to occur are the most strongly accented beats in a measure, and this was also found in subsequent studies using both Western classical and folk music corpora (Huron & Ommen, 2006; Temperley, 2010). We present a rhythmic analysis of a corpus of 15 performances of percussion music from Bamako, Mali. In our corpus, the relative frequency of note onsets in a given metrical position does not correspond to patterns of metrical accent, though there is a stable relationship between onset frequency and metrical position. The implications of this non-congruence between simple statistical likelihood and metrical structure for the ways in which meter and metrical accent may be learned and understood are discussed, along with importance of cross-cultural studies for psychological research.     

Who Reaps the Benefits of Social Change? Exploration and Its Socioecological Boundaries

We investigated the interplay between the personality trait exploration and objective socioecological conditions in shaping individual differences in the experience of two individual‐level benefits of current social change: new lifestyle options, which arise from the societal trend toward individualization, and new learning opportunities, which accrue from the societal trend toward lifelong learning. We hypothesized that people with higher trait exploration experience a greater increase in lifestyle options and learning opportunities––but more so in social ecologies in which individualization and lifelong learning are stronger, thus offering greater latitude for exploring the benefits of these trends. We employed structural equation modeling in two parallel adult samples from Germany (N = 2,448) and Poland (N = 2,571), using regional divorce rates as a proxy for individualization and Internet domain registration rates as a proxy for lifelong learning. Higher exploration was related to a greater perceived increase in lifestyle options and in learning opportunities over the past 5 years. These associations were stronger in regions in which the trends toward individualization and lifelong learning, respectively, were more prominent. Individuals higher in exploration are better equipped to reap the benefits of current social change––but the effects of exploration are bounded by the conditions in the social ecology.     

Belonging to a majority reduces the immediate need threat from ostracism in individuals with a high need to belong

Ostracism—being ignored and excluded—threatens the basic human needs for belonging, self‐esteem, control, and meaningful existence. This work introduces belonging to a majority as a buffer against the immediate negative impact of ostracism on basic needs for individuals with a high need to belong, for whom social groups are especially relevant. Three studies show that for individuals high in the need to belong, need threat was attenuated by membership in a majority group, but not by membership in a minority group (Studies 1 and 3) or a group of unknown size (Study 2). By contrast, individuals low in the need to belong—who place less importance on group membership in general—did not benefit from belonging to a majority group. The general pattern replicated across different manipulations of group membership and social exclusion, with two measures of need threat, and with participants from two different countries.     

D-optimal design for the Rasch counts model with multiple binary predictors

In this paper we derive optimal designs for the Rasch Poisson counts model and its extended version of the (generalized) negative binomial counts model incorporating several binary predictors for the difficulty parameter. To efficiently estimate the regression coefficients of the predictors, locally D-optimal designs are developed. After an introduction to the Rasch Poisson counts model and its extension, we will specify these models as particular generalized linear models. Based on this embedding, optimal designs for both models including several binary explanatory variables will be presented. Therefore, we will derive conditions on the effect sizes for certain designs to be locally D-optimal. Finally, it is pointed out that the results derived for the Rasch Poisson models can be applied for more general Poisson regression models which should receive more attention in future psychological research.     

Substance and artifact in the higher-order factors of the Big Five

J. M. Digman (1997) proposed that the Big Five personality traits showed a higher-order structure with 2 factors he labeled alpha and beta. These factors have been alternatively interpreted as heritable components of personality or as artifacts of evaluative bias. Using structural equation modeling, the authors reanalyzed data from a cross-national twin study and from American cross-observer studies and analyzed new multimethod data from a German twin study. In all analyses, artifact models outperformed substance models by root-mean-square error of approximation criteria, but models combining both artifact and substance were slightly better. These findings suggest that the search for the biological basis of personality traits may be more profitably focused on the 5 factors themselves and their specific facets, especially in monomethod studies.     

The Medical Humanities Today: Humane Health Care or Tool of Governance?

The medical humanities have been presented as a panacea for medical reductionism; a means for 'humanizing' medicine. However, there is a lack of consensus about the appropriate contributing disciplines and how curricula should be taught and assessed. This special issue critically examines the role of the medical humanities in medical education and their potential to serve, inadvertently or otherwise, as a tool of governance. The contributors, who include medical educators and medical practitioners, employ a range of perspectives for analysing the pertinent issues.
