A1 - Engbert, Ralf T1 - Likelihood-based parameter estimation and comparison of dynamical cognitive models JF - Psychological Review N2 - Dynamical models of cognition play an increasingly important role in driving theoretical and experimental research in psychology. Therefore, parameter estimation, model analysis and comparison of dynamical models are of essential importance. In this article, we propose a maximum likelihood approach for model analysis in a fully dynamical framework that includes time-ordered experimental data. Our methods can be applied to dynamical models for the prediction of discrete behavior (e.g., movement onsets); in particular, we use a dynamical model of saccade generation in scene viewing as a case study for our approach. For this model, the likelihood function can be computed directly by numerical simulation, which enables more efficient parameter estimation including Bayesian inference to obtain reliable estimates and corresponding credible intervals. Using hierarchical models inference is even possible for individual observers. Furthermore, our likelihood approach can be used to compare different models. In our example, the dynamical framework is shown to outperform nondynamical statistical models. Additionally, the likelihood based evaluation differentiates model variants, which produced indistinguishable predictions on hitherto used statistics. Our results indicate that the likelihood approach is a promising framework for dynamical cognitive models.

However, the interrelatedness of these two number couplings is still unclear. The present study examines the simultaneous occurrence of space- and size-numerical congruency effects and their interactions both within and across trials, in a magnitude judgment task physically small or large digits were presented left or right from screen center. The reaction times analysis revealed that space- and size-congruency effects coexisted in parallel and combined additively. Moreover, a selective sequential modulation of the two congruency effects was found. The size-congruency effect was reduced after size incongruent trials. The space-congruency effect, however, was only affected by the previous space congruency. The observed independence of spatial-numerical and within magnitude associations is interpreted as evidence that the two couplings reflect Different attributes of numerical meaning possibly related to orginality and cardinality.

In clinical practice, it has been found that the implementation of clinical supervision varies substantially and often differs from the recommendations made in the literature. The objective of the current study was to investigate the frequency of topics (e.g. ethical issues) and techniques (e.g. role play) in the clinical supervision of psychotherapy trainees in Germany. To this end, we considered supervisions in cognitive behavioural therapy (CBT) and psychodynamic therapy (PT). A total of 791 psychotherapy trainees (533 CBT and 242 PT) were asked via the internet to provide information about their current supervision sessions. We found that clinical supervision in psychotherapy training addressed topics that are central for the effective treatment of supervised patients (i.e. therapeutic interventions, therapeutic alliance, maintaining factors, and therapeutic goals). However, the most frequently used intervention in clinical supervision in psychotherapy training was case discussion. Rarely were techniques used that allowed the supervisor to give the supervisee feedback based on the supervisee's demonstrated competencies. For example, 46% of the supervisors never used audiotapes or videotapes in the supervision. Differences between CBT and PT were rather small. Current practice regarding the techniques used in clinical supervision for psychotherapy trainees contradicts recommendations for active and feedback-oriented clinical supervision. Thus the potential of clinical supervision might not be fully used in clinical practice.

B. T1 - Personality disorders in hypochondriasis BT - a comparison to panic disorder and healthy controls JF - Journal of personality disorders N2 - Previous studies found high prevalence rates of personality disorders (PDs) in patients with hypochondriasis; however, assessment was often based only on questionnaires. In the current study, a sample of 68 patients with hypochondriasis was compared to 31 patients with panic disorder and to 94 healthy controls. Participants were investigated with the Structured Clinical Interview for DSM-IV Personality Disorders questionnaire (SCID-II questionnaire) and the SCID-II interview. Based on the cut-off scores of the SCID-II questionnaire, we found a prevalence rate of 45.6% for PD in patients with hypochondriasis. In comparison to healthy controls, patients with hypochondriasis showed characteristics of paranoid, borderline, avoid ant, and-dependent PDs in the dimensional assessment significantly more often. However, no significant differences were found between the clinical samples. Based on the SCID-II interview, only 2.9% of the patients with hypochondriasis fulfilled the criteria for a PD. These results suggest that PDs are not a specific characteristic of hypochondriasis.

However, to date, underlying neuronal mechanisms of these WM load-dependent activation changes in aging remain poorly understood. The aim of this study was to investigate these mechanisms in terms of effective connectivity by application of dynamic causal modeling with Bayesian Model Selection. Eighteen healthy younger (age: 20-32 years) and 32 older (60-75 years) participants performed an n-back task with 3 WM load levels during functional magnetic resonance imaging (fMRI). Behavioral and conventional fMRI results replicated age group by WM load interactions. Importantly, the analysis of effective connectivity derived from dynamic causal modeling, indicated an age-and performance-related reduction in WM load-dependent modulation of connectivity from dorsolateral prefrontal cortex to inferior parietal lobule. This finding provides evidence for the proposal that age-related WM decline manifests as deficient WM load-dependent modulation of neuronal top-down control and can integrate implications from theoretical models and previous studies of functional changes in the aging brain.

Participants (N-1 = 32, N-2 = 40) read sentences with subject- and object-extracted relative clauses, where thematic agents and patients remained ambiguous until the end of the relative clause. The results reveal a linguistic gender bias: agent roles are assigned more easily to grammatically masculine than feminine role nouns and stereotypically neutral than female ones. The opposite pattern is observed in the assignment of patient roles for stereotypical but not grammatical gender. The findings are discussed within the framework of situation model theories as well as in constraint-based and similarity-based interference accounts, while gender is viewed as a dimension of prominence.

Design: Cross-sectional observation study. Setting: Neurology, orthopedic, and cardiology rehabilitation clinics. Participants: Patients (N=4610; age, 18-65y) with work anxieties. Interventions: Not applicable. Main Outcome Measures: Patients who scored high on at least 2 of 9 items in the work-anxiety screening questionnaire and who reported impairment were investigated with a differential diagnostic interview on work anxieties and with the Mini-International Neuropsychiatric Interview on non work-related common mental disorders. Patients also filled out a self-rating questionnaire on their subjective symptom load and sociodemographic data. Results: Approximately 20% to 27% of the investigated inpatients in somatic rehabilitation (altogether n=393) received a work-anxiety diagnosis. Patients with orthopedic illness report highest work anxiety and have previous longest sick leave (20.6wk in the past 12mo). Patients with orthopedic illness suffer from work-related adjustment disorder with anxiety, social anxieties, and workplace phobias, whereas patients with cardiac illness are more often affected by hypochondriac anxieties. Anxieties of insufficiency and worrying occur equally in all indications. Conclusions: About a quarter of patients in somatic rehabilitation are in need of additional diagnostic attention owing to work anxieties. Differential diagnostic of work anxiety is needed for initiating adequate therapeutic action. Somatic rehabilitation physicians should be aware of work anxieties in their patients, especially in patients with orthopedic illness with previous long-term sick leave.

We investigated the comprehension of subject and object wh-questions in both Turkish, a wh-in-situ language, and German, a wh-fronting language, in two bilingual PWA using a sentence-to-picture matching task. Both PWA showed differential impairment patterns in their two languages. SK, an early bilingual PWA, had particular difficulty comprehending subject which-questions in Turkish but performed normal across all conditions in German. CT, a late bilingual PWA, performed more poorly for object which-questions in German than in all other conditions, whilst in Turkish his accuracy was at chance level across all conditions. We conclude that the observed patterns of selective cross-linguistic impairments cannot solely be attributed either to difficulty with wh-movement or to problems with the integration of discourse-level information. Instead our results suggest that differences between our PWA’s individual bilingualism profiles (e.g. onset of bilingualism, premorbid language dominance) considerably affected the nature and extent of their impairments.

In this study, discourse coherence in non-brain-damaged (NBD) speakers and speakers with anomic aphasia was investigated quantitatively and qualitatively. Method: Fifteen native speakers of Cantonese with anomic aphasia and 15 NBD participants produced 60 language samples. Elicitation tasks included story-telling induced by a picture series and a procedural description. The samples were annotated for discourse structure in the framework of Rhetorical Structure Theory (RST) in order to analyse a number of structural parameters. After that 20 naive listeners rated coherence of each sample. Result: Disordered discourse was rated as significantly less coherent. The NBD group demonstrated a higher production fluency than the participants with aphasia and used a richer set of semantic relations to create discourse, particularly in the description of settings, expression of causality, and extent of elaboration. People with aphasia also tended to omit essential information content. Conclusion: Reduced essential information content, lower degree of elaboration, and a larger amount of structural disruptions may have contributed to the reduced overall discourse coherence in speakers with anomic aphasia.

A1 - Lensing, Johanna Nele A1 - Fay, Doris T1 - Personal initiative BT - Developmental predictors and positive outcomes from childhood to early adolescence JF - Journal of Applied Developmental Psychology N2 - Although the effects of personal initiative (PI) on adults' performance and other favorable outcomes are well documented, research has only recently begun to study PI in childhood. This study aimed at examining the development of PI, its predictors, and its developmental effects from childhood to early adolescence. A total of 1,593 German children participated in a longitudinal study starting at Grades 2 to 4, with a second measurement wave two years later. Latent change score analyses revealed that 1) children differed significantly in their change scores of PI, that 2) executive functions and positive parenting predicted change scores in PI, and that 3) high initial levels and change scores in PI reduced the development of internalizing and externalizing problems and supported the development of prosocial behavior and academic competencies. These findings endorse the plasticity of PI and shed light on the active part of children in promoting their own development.
