The non-native group was comprised of native German-speaking, proficient non-native speakers of English. Both participant groups showed evidence of linking fronted indirect objects to the subcategorizing verb when this was encountered, reflected in an N400 component. Evidence for continued filler activation beyond the verb was seen only in the non-native group, in the shape of a prolonged left-anterior negativity. Both participant groups showed sensitivity to filled indirect object gaps reflected in a P600 response, which was more pronounced and more globally distributed in our non-native group. Taken together, our results indicate that resolving indirect object dependencies is a two-step process in both native and non-native sentence comprehension, with greater processing cost incurred in non-native compared to native comprehension.

We pooled two independently collected longitudinal data sets (N = 760 at Wave 1) and used time-varying effect modeling (TVEM) to show that the frequency of parent-adolescent conflict increased during early adolescence (12 years), peaked at mid adolescence (16 years), and gradually decreased throughout late adolescence and young adulthood. In general, parent-adolescent conflict was associated with negative adjustment (more depressive symptoms and lower GPA) more strongly during mid-to late-adolescence (15 to 17 years) compared with other developmental periods. These time-varying associations differed slightly by gender, at least for GPA. Our findings provide important developmental knowledge of parent-adolescent conflict for Chinese American youth and suggest that attention to conflict and links to adjustment is especially relevant during mid to late adolescence. Our study also illustrates the usefulness of integrative data analysis and TVEM to investigate how the strength of conflict-adjustment associations might change throughout development.

Latent profile analysis yielded three configurations of risk factors, made up of a non-risk group, a risk group scoring high on measures of social rejection (SR), and a risk group scoring high on measures of affiliation with aggressive peers and academic failure (APAF). Latent path analysis revealed that, as predicted, only membership in the SR group at T1 predicted reactive aggression at T2 17 months later.

Ergebnisse: Das auf Basis der Interviews erstellte Kategoriensystem umfasste die Kategorien „Erwartungen an das Feedback“, „Wahrnehmung des Feedbacks“, „Verarbeitung von und Umgang mit Feedback“, „Folgen, Auswirkungen und Veränderungen durch Feedback“ sowie „Verbesserungswünsche“. Schlussfolgerungen: Therapeuten streben eine Umsetzung des Feedbacks an, welches sich auf die Behandlung, die Supervision, die eigene Person und die therapeutische Beziehung auswirkt. N2 - Background: To date, the influence of therapist-oriented feedback in psychotherapy training has rarely been investigated. Objective: How do therapists in training deal with competence feedback? What influence does a regular competence feedback have on treatment quality (especially therapy sessions, therapeutic alliance, the therapist, supervision)? Method: We interviewed 11 therapists using a semistructured interview guide. The text material was analyzed with qualitative content analysis (Mayring, 2015). Results: The interview-based system of categories consists of: expectations toward feedback; perception of feedback; processing of feedback; consequences, effects, and changes due to feedback; and suggestions for improvement. Conclusion: Therapists strive to implement feedback. Competence feedback has an impact on treatment, supervision, the therapist, and the therapeutic alliance.

Although previous reviews have focused chiefly on design pitfalls and instances of false reasoning, we show in this study that the choice of analysis pathway can have severe effects on the statistical output when applied to bCFS data. Using a representative dataset designed to address a specific controversy in the realm of language processing under bCFS, namely whether psycholinguistic variables affect access to awareness, we present a range of analysis methods based on real instances in the published literature, and indicate how each approach affects the perceived outcome. We provide a summary of published bCFS studies indicating the use of data transformation and trimming, and highlight that more compelling analysis methods are sparsely used in this field. We discuss potential interpretations based on both classical and more complex analyses, to highlight how these differ. We conclude that an adherence to openly available data and analysis pathways could provide a great benefit to this field, so that conclusions can be tested against multiple analyses as standard practices are updated.

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.

The present study related positive and negative facets of a masculine and feminine self-concept to aggressive and adaptive forms of anger expression while driving. A sample of 417 drivers (194 women, 46.5%) in Germany completed the Positive-Negative Sex Role Inventory (PN-SRI) as a measure of positive and negative masculinity and femininity and the Driving Anger Expression Inventory (DAX) as a measure of driving anger expression. Aggressive forms of expressing driving anger were unrelated to gender but differed significantly in relation to gendered self-concept. Negative but not positive masculinity was found to predict higher aggressive and lower adaptive anger expression. No main effects of positive or negative femininity were found. However, the link between negative masculinity and aggressive anger expression was buffered by positive femininity: Negative masculinity was unrelated to aggressive anger expression when accompanied by positive femininity. Adaptive anger expression showed negative links with negative masculinity and positive links with positive masculinity. The findings held for both men and women and support the theoretical distinction between positive and negative facets of the gendered self-concept. The implications for the conceptualization of both gendered self-concept and anger expression on the road are discussed.

Method: Male and female college students (N = 2,425) in Germany participated in the study that comprised 3 data waves in their first, second, and third year of university, separated by 12-month intervals. Sexual assault victimization was assessed at Time 1 (T1) since the age of 14 and at Time 2 (T2) and Time 3 (T3) for the last 12 months. Depression and sexual self-esteem were measured at each wave. Results: Random-intercept cross-lagged panel analyses, controlling for individual differences in depression and sexual self-esteem, showed that sexual assault at T1 predicted depression and lower sexual self-esteem at T2, and depression and lower self-esteem at T2 predicted sexual assault victimization at T3. In addition, significant paths were found from T1 depression to T2 sexual assault victimization and from T2 sexual assault victimization to depression at T3. Sexual victimization at T1 was indirectly linked to sexual victimization at T3 via depression at T2. Both depression and sexual self-esteem at T1 were indirectly linked to sexual victimization at T3. The paths did not differ significantly between men and women. Conclusion: Sexual assault victimization was shown to be a risk factor for both depression as a general mental health indicator and lowered sexual self-esteem as a specific outcome in the domain of sexuality. Moreover, depression and sexual self-esteem increased the vulnerability for sexual assault victimization, which has implications for prevention and intervention efforts.

In three experiments, participants had to detect a physically large (or small) target item among physically small (or large) distractors in a search task comprising single-digit numbers. The relative numerical size of the digits was varied, such that the target item was either among the numerically large or small numbers in the search display and the relation between numerical and physical size was either congruent or incongruent. Perceptual differences of the stimuli were controlled by a condition in which participants had to search for a differently coloured target item with the same physical size and by the usage of LCD-style numbers that were matched in visual similarity by shape transformations. The results of all three experiments consistently revealed that detecting a physically large target item is significantly faster when the numerical size of the target item is large as well (congruent), compared to when it is small (incongruent). This novel finding of a size congruity effect in visual search demonstrates an interaction between numerical and physical size in an experimental setting beyond typically used binary comparison tasks, and provides important new evidence for the notion of shared cognitive codes for numbers and sensorimotor magnitudes. Theoretical consequences for recent models on attention, magnitude representation and their interactions are discussed.

One of the first-line recommended treatment options is eye movement desensitization and reprocessing (EMDR). The number of studies assessing the effectiveness of EMDR in German soldiers under routine conditions is currently almost nil. Methods: A retrospective, quasi-experimental effectiveness study on EMDR in an inpatient setting is presented using a prepost design. The study compares symptom reduction in soldiers (N = 78) with a wait-list (N = 18). Effect sizes of EMDR were measured for PTSD, symptoms of depression, and general mental health. Results: Effect size for EMDR treatment of PTSD was d = 0.77; 95% confidence interval (CI): 0.51 to 1.36, for symptoms of depression d = 0.99; 95% CI: 0.31 to 1.36, and for general psychiatric symptoms d = 0.53; 95% CI: 0.17 to 1.21. The effects resulting from EMDR treatment were somewhat weaker than those reported in comparable studies in civilians. Conclusion: EMDR therapy is an effective treatment to reduce symptoms of PTSD and depression. However, in the military context it needs to be complemented by treatment options that specifically address further conditions perpetuating the disorders.

The present study assessed the lifetime prevalence of controlled performance and appearance enhancing substances ( PAES), and used behavioral reasoning theory to identify the reasons for using and for avoiding using controlled PAES in young exercisers across five European countries, in the context of the "SAFE YOU" Project. Participants were 915 young amateur athletes and exercisers (M = 21.62; SD = 2.62) from Cyprus, Germany, Greece, Italy, and UK who completed an anonymous questionnaire that included measures of self-reported use of controlled PAES, as well as reasons for using and not using controlled PAES. The results of the descriptive analyses demonstrated that almost one out five exercisers in the sample had a previous experience with controlled PAES. Higher prevalence rates were found in Greece and Cyprus and lower in Italy. The most frequently reported reasons for using controlled PAES included achieving the desired results faster; pushing the self to the (physical) limits; and recovering faster after exercise/training. Furthermore, the most frequently reported reasons for not using controlled PAES involved worry about any possible adverse health effects; not feeling the need for using them; and wanting to see what can be achieved naturally without using any controlled PAES. The findings of the present study indicate that the use of controlled PAES is fast becoming a crisis in amateur sports and exercise settings and highlight the need for preventive action and concerted anti-doping education efforts.

The current study extended this approach to situated aggression control to withdrawal-related negative emotions. We proposed that even a negative affective state can be incompatible with aggression if its basic motivational orientation counteracts the approach orientation underlying anger and aggression. Specifically, we predicted that although it is inherently negative, sadness may reduce anger-driven aggressive behavior. Method: An experiment was conducted (N = 149) in which half the participants were angered by means of a frustrating number-sequences task, whereas the other half were asked to engage in a similar but nonfrustrating task. To counteract anger-driven aggressive behavior, sadness was induced in half the participants by asking them to recall a sad personal episode. Participants in the no-sadness group recalled an affectively neutral episode. Finally, participants were asked to choose the difficulty level of the number sequences that would ostensibly be assigned to future participants, with the number of difficult sequences chosen indicating the strength of the aggressive response. Results: As predicted, the induction of sadness buffered anger-related aggressive behavior. Anger translated into aggression in the control condition but not in the sadness condition. The aggression-inhibiting effect of the experience of sadness was found to be driven by the compensating coactivation of anger and sadness. Conclusions: The results support the extension of the incompatible response hypothesis to withdrawal-related negative emotions and shed further light on the underlying processes.

Over 400 items relating to four types of discounting were generated. Next, a study followed by a series of psychometric analyses of data obtained from a group of 2843 individuals was conducted. Principal Component Analysis yielded a four-factor structure of data, reflecting the four types of discounting. The results of Confirmatory Factor Analysis showed good fit of the four-factor model to data. Through several iterations of retaining and deleting items on the basis of their component loadings, item intercorrelations, and contribution to coefficient alphas, the total number of items was reduced to 48. The final 48-item version of the inventory has satisfactory psychometric characteristics, including Cronbach's alpha and test-retest stability. In addition, significant correlations were observed between the DI and traditional discounting instruments, suggesting that the DI measures a construct similar to the behavioral discounting process. The development of the tool was based on the assumption that discounting is a personality trait. However, the present data suggest that discounting may reflect more a state than trait function.

However, the concept of academic language is generally the subject of much debate, and there is no consensus yet on what constitutes academic listening comprehension. To date, it remains unclear whether listening comprehension of academic language may be regarded as a distinct construct. The present study investigates the distinction of academic and everyday listening comprehension in 459 ninth-grade students speaking German as a first language or as a second language. Empirical results provide preliminary evidence that academic listening forms a separate facet of listening comprehension. Contrary to theoretical assumptions, second language students were not particularly disadvantaged in terms of academic listening comprehension.

Some of these interactions actually arise from the presence of unspecified nonlinear main effects and statistically dependent covariates in the statistical model. Importantly, such nonlinear main effects may be compatible (or, at least, not incompatible) with the current theoretical framework. In the present literature, this issue has only been studied in terms of correlated (linearly dependent) covariates. Here we generalize to nonlinear main effects (i.e., main effects of arbitrary shape) and dependent covariates. We propose a novel nonparametric method to test for ambiguous interactions where present parametric methods fail. We illustrate the method with a set of simulations and with reanalyses (a) of effects of parental education on their children’s educational expectations and (b) of effects of word properties on fixation locations during reading of natural sentences, specifically of effects of length and morphological complexity of the word to be fixated next. The resolution of such ambiguities facilitates theoretical progress.

T1 - EEG Source Imaging Indices of Cognitive Control Show Associations with Dopamine System Genes JF - Brain Topography N2 - Cognitive or executive control is a critical mental ability, an important marker of mental illness, and among the most heritable of neurocognitive traits. Two candidate genes, catechol-O-methyltransferase (COMT) and DRD4, which both have a roles in the regulation of cortical dopamine, have been consistently associated with cognitive control. Here, we predicted that individuals with the COMT Met/Met allele would show improved response execution and inhibition as indexed by event-related potentials in a Go/NoGo task, while individuals with the DRD4 7-repeat allele would show impaired brain activity. We used independent component analysis (ICA) to separate brain source processes contributing to high-density EEG scalp signals recorded during the task. As expected, individuals with the DRD4 7-repeat polymorphism had reduced parietal P3 source and scalp responses to response (Go) compared to those without the 7-repeat. Contrary to our expectation, the COMT homozygous Met allele was associated with a smaller frontal P3 source and scalp response to response-inhibition (NoGo) stimuli, suggesting that while more dopamine in frontal cortical areas has advantages in some tasks, it may also compromise response inhibition function. An interaction effect emerged for P3 source responses to Go stimuli. These were reduced in those with both the 7-repeat DRD4 allele and either the COMT Val/Val or the Met/Met homozygous polymorphisms but not in those with the heterozygous Val/Met polymorphism. This epistatic interaction between DRD4 and COMT replicates findings that too little or too much dopamine impairs cognitive control. The anatomic and functional separated maximally independent cortical EEG sources proved more informative than scalp channel measures for genetic studies of brain function and thus better elucidate the complex mechanisms in psychiatric illness.

A community sample of N = 924 German children and early adolescents (51.8% male) completed depressive symptoms and dysfunctional attitudes measures at T1 and again 20 months later (T2). Stressful life events were reported at T2. Dysfunctional attitudes were unrelated to stress generation. Interpersonal, but not noninterpersonal, dependent stress partially mediated the relationship between initial and later depressive symptoms, with girls being more likely to generate interpersonal stress in response to depressive symptoms. Findings underscore the role of interpersonal stress generation in the early development of depressive symptomatology, and in the gender difference in depression prevalence emerging around puberty.

An initially asymptomatic sample of 889 youths aged 9–18 years completed measures of dysfunctional attitudes and depressive symptoms. Twenty months later, participants reported stressful life events and current depressive symptoms. Results support a threshold view of cognitive vulnerability as only dysfunctional attitudes above a certain threshold significantly interacted with life events to predict depressive symptoms. Thus, findings suggest that dysfunctional attitudes must exceed a certain threshold to confer vulnerability to depressive symptomatology in youth. The term “dysfunctional” might therefore only apply to higher levels of the “dysfunctional attitudes” proposed by A. T. Beck. Results also indicate that studies using non-clinical samples may systematically underestimate the effect of dysfunctional attitudes when relying on conventional linear methods.
