Musiktherapie bei chronisch-tonalem Tinnitus

Tinnitus therapy according to the Heidelberg model of music therapy integrates psychological strategies in order to manage the perception and approaches to tinnitus aimed at curing the underlying somatic disorder. The specific musical therapeutic interventions as well as the postulated specific effective factors are explained. Several multidisciplinary studies support the effectiveness of this form of therapy. The results indicate that the therapy is highly advantageous in terms of treatment duration, effectiveness, and follow-up stability compared to customary interventions. Furthermore, the results of brain imaging strongly suggest the usefulness of further investigations and discussion in the realm of neuronal modeling of chronic tinnitus.     

Tonic Activity Level in the Right Prefrontal Cortex Predicts Individuals' Risk Taking

ABSTRACT— Human risk taking is characterized by a large amount of individual heterogeneity. In this study, we applied resting-state electroencephalography, which captures stable individual differences in neural activity, before subjects performed a risk-taking task. Using a source-localization technique, we found that the baseline cortical activity in the right prefrontal cortex predicts individual risk-taking behavior. Individuals with higher baseline cortical activity in this brain area display more risk aversion than do other individuals. This finding demonstrates that neural characteristics that are stable over time can predict a highly complex behavior such as risk-taking behavior and furthermore suggests that hypoactivity in the right prefrontal cortex might serve as a dispositional indicator of lower regulatory abilities, which is expressed in greater risk-taking behavior.     

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.     

Bias and regulation of bias in intergroup interactions: Implicit attitudes toward Muslims and interaction quality

Previous research suggests that automatically activated bias manifests itself in behavior that can jeopardize the quality of intergroup interactions. However, regulation of automatic associations has the potential to attenuate their influence on intergroup interaction. To test this possibility, 46 non-Muslim White participants interacted with a Muslim confederate and completed an implicit measure of attitudes toward Muslims. The Quadruple Process model [Sherman, J. W., Gawronski, B., Gonsalkorale, K., Hugenberg, K., Allen, T. J., & Groom, C. J. (2008). The self-regulation of automatic associations and behavioral impulses. Psychological Review, 115, 314-335] was applied to the implicit measure to estimate participants’ strength of negative associations with Muslims and their ability to overcome those negative associations. The confederate’s ratings of how much he liked the participants were predicted by an interaction between automatic negative associations and the ability to overcome them. Specifically, when the strength of participants’ negative associations with Muslims was low, participants’ level of overcoming bias was unrelated to the confederate’s ratings. In contrast, the ability to regulate automatic negative associations predicted greater liking when those associations were strong.     

Effectance and control as determinants of video game enjoyment.

This article explores video game enjoyment originated by games' key characteristic, interactivity. An online experiment (N=500) tested experiences of effectance (perceived influence on the game world) and of being in control as mechanisms that link interactivity to enjoyment. A video game was manipulated to either allow normal play, reduce perceived effectance, or reduce perceived control. Enjoyment ratings suggest that effectance is an important factor in video game enjoyment but that the relationship between control of the game situation and enjoyment is more complex.     

At your own peril: An ERP study of voluntary task set selection processes in the medial frontal cortex

A tool that is commonly used to investigate selection among different alternatives in a changing environment is the task-switching paradigm. Functional neuroimaging has pointed out a role for the posterior medial frontal cortex and the posterior parietal cortex in the voluntary selection of task sets. In the present study, we set out to investigate the temporal dynamics of these agency-related processes (in task choice vs. no-choice conditions) using event-related brain potentials (ERPs). The results revealed agency-related modulations of a series of ERP components, including (1) an early parieto-occipital activation, taken to reflect the evaluation of choice versus no choice; (2) a subsequent medial frontal expression of the voluntary selection between task sets; (3) a CNV-like sustained negativity in preparation for the target; (4) a target-induced N210—P210 complex, taken to reflect early sensory-perceptual processing; and (5) a target-induced P3, associated with the evaluation of the stimulus and its designated response vis-à-vis the chosen versus competing task sets. Together, these results indicate that the opportunity to choose between tasks invokes activity originating from the medial frontal cortex, associated with voluntary task set selection, but also activation at different time points in a number of other brain areas, not necessarily captured by functional neuroimaging.     

HMMTree: A computer program for latent-class hierarchical multinomial processing tree models

Latent-class hierarchical multinomial models are an important extension of the widely used family of multinomial processing tree models, in that they allow for testing the parameter homogeneity assumption and provide a framework for modeling parameter heterogeneity. In this article, the computer program HMMTree is introduced as a means of implementing latent-class hierarchical multinomial processing tree models. HMMTree computes parameter estimates, confidence intervals, and goodness-of-fit statistics for such models, as well as the Fisher information, expected category means and variances, and posterior probabilities for class membership. A brief guide to using the program is provided.     

Process components of the Implicit Association Test: a diffusion-model analysis

The authors present a diffusion-model analysis of the Implicit Association Test (IAT). In Study 1, the IAT effect was decomposed into 3 dissociable components: Relative to the compatible phase, (a) ease and speed of information accumulation are lowered in the incompatible phase, (b) more cautious speed-accuracy settings are adopted, and (c) nondecision components of processing require more time. Studies 2 and 3 assessed the nature of interindividual differences in these components. Construct-specific variance in the IAT relating to the construct to be measured (such as implicit attitudes) was concentrated in the compatibility effect on information accumulation (Studies 2 and 3), whereas systematic method variance in the IAT was mapped on differential speed-accuracy settings (Study 3). Implications of these dissociations for process theories of the IAT and for applications are discussed.
