Strategy Induction Enhances Creativity in Figural Divergent Thinking

Instructional effects in creative‐thinking tasks are important to understand in order to promote creative performance of individuals. In divergent‐thinking tasks, for example, instructional and strategic enhancement effects have been extensively studied for verbal tasks. However, while studies on instructional enhancement effects on creative drawing tasks exist, it is surprising that strategy enhancement in figural divergent thinking is still underresearched. In this study, we used a strategy manipulation approach to reassess the role of executive strategy implementation and the moderating role of an indicator of fluid intelligence, figural analogical reasoning, in two types of figural divergent‐thinking tasks (abstract vs. concrete). The sample comprised N = 75 high‐school students. Importantly, we found strategic enhancement effects by combining strategy instructions with a prompt to “be creative.” This combined instruction was contrasted with a standard instruction, and main effects were found for overall, concrete, and abstract creativity. Moreover, we found in a regression analysis a main effect for figural analogical reasoning on overall creativity and creativity for only the concrete object tasks. An expected interaction effect of instruction and figural analogical reasoning was not found. As another addition, the role of current motivation in figural divergent thinking was explored.     

Mixing costs and switch costs when switching stimulus dimensions in serial predictions

Mixing costs and switch costs are two markers for the costs that arise in multitasking situations. To further explore mixing costs and switch costs, we used a serial prediction task in which subjects switched between stimulus dimensions (i.e., color, form, and position). Using this task, we demonstrate that both mixing costs and switch costs are influenced by task conflict and the resolution of interference. Here, we show that both mixing costs and switch costs are affected by a local factor, namely the necessity to resolve interference in the current trial in mixed blocks. However, whereas mixing costs can be sufficiently explained by interference resolution in the current trial, switch costs are also affected by carry-over effects from the preceding trial. As regards these carry-over effects, the present paradigm enabled us to demonstrate the influence of both persisting activation and persisting inhibition on the performance in switch trials.     

Cross-cultural examination of the tripartite model in adults

Clark and Watson's (1991) tripartite model is commonly viewed as the preferred model for examining the relationship between anxiety and depression. The tripartite model proposes that the overlap and distinction between anxiety and depression can be best understood along three dimensions: positive affect, negative affect, and physiological hyperarousal. Although the tripartite model has received support in a wide variety of samples, little has been done to examine whether the tripartite model holds cross-culturally. Using a highly diverse sample of undergraduate students (n = 923), this study set out to determine the generalizability of the tripartite model among students who identified themselves as African American/Black (non-Hispanic), Caucasian/White (non-Hispanic), Hispanic/Latino(a), and Asian. The results of the present study suggest that the model fits generally for each group, but the study did not find cross-group equivalence in the relationships between constructs. Possible reasons for the lack of cross-group equivalence, as well as limitations of this study, are also discussed.     

Paruresis

The paruretic disorder, a special subtype of social phobia, is presented. It has been almost completely neglected by German research. The disorder manifests in an inability to urinate in public rest rooms. The corresponding fears concern the loss of visual and/or acoustic privacy. Based on considerations about its etiology and pathogenesis a cognitive behavior-therapeutic intervention is recommended. This is illustrated by a case vignette of a 29-year-old male patient.     

Behavioral phenotyping of a murine model of Alzheimer’s disease in a seminaturalistic environment using RFID tracking

Neurodegen erative disorders such as Alzheimer’s disease (AD) are increasingly threatening public health. Most animal models of AD consist of transgenic mice that are usually housed singly or in unisexual groups in small barren cages. Such restricted environments, however, prevent the mice from showing a variety of speciesspecific behaviors and consequently may constrain comprehensive behavioral phenotyping. On the other hand, allowing the animals to freely organize their lives in a spacious physically and socially enriched environment makes behavioral phenotyping laborious and time consuming. Radio frequency identification (RFID) using a network of antennae and small glass-coated transponders labeling each individual allows for gathering spatiotemporal information about a large number of individuals in parallel. The aim of this project was to use the RFID technique to facilitate the characterization of mice carrying a genetic disposition to develop AD-like pathology and of their wild-type conspecifics in a spacious seminaturalistic environment.     

Beyond “accident-proneness”: Using Five-Factor Model prototypes to predict driving behavior

Research on the association between personality traits and driving behavior as well as accident involvement has produced mixed results. In order to obtain empirical evidence for a consistent relation between personality and driving behavior, a prototype approach based on the Five-Factor Model (FFM) was applied. In two samples of drivers, cluster analyses of FFM scales revealed three prototypes that replicate previous ones. The prototypes, labeled Resilient, Overcontrolled, and Undercontrolled, were found to differ reliably in accident involvement and driving behavior, indicating differential accident liability. Undercontrollers are the most problematic drivers followed by Resilients, whereas Overcontrollers most consistently obey traffic rules and drive accordingly.     

Family relations as perceived by emotionally disturbed and normal boys

The perception of feelings within the family of 9-13-year-old boys were studied. The purpose was to determine the sensitivity of the Family Relations Test (FRT) in discriminating between inpatients, outpatients, and normal controls. Both patient groups more frequently identified family members as sources of negative feelings than normal controls. Inpatients expressed more self-flattery and self-criticism and an absence of a reciprocal, positive relationship with their fathers. The FRT is only able to make a few quantitative differentiations between a clinical and a normal sample of boys but certain qualitative aspects of the responses were particularly noteworthy.     

Psychosis in German prisoners: Comparison of the clinical appearance of psychotic disorder of an imprisoned population with a not detained community group

Surveys confirm risk factors for the incarceration of patients with psychosis including homelessness and comorbidity. There is also agreement that severe psychosis can lead to violence. Data describing prisoners with psychosis in Germany are scarce. We aimed to compare patients with psychosis in a prison hospital and patients with psychosis in a community hospital. Demographic data were collected, as well as comorbidity in the form of substance dependence and a psychiatric assessment using the German version of the 18-item Brief Psychiatric Rating Scale (BPRS) and the Positive and Negative Syndrome Scale (PANSS). In the prison hospital group more patients were homeless (17 versus 2%) and non-German (36 versus 4%). There were also more patients with substance dependence or abuse in the prison hospital group. The total scores of BPRS and PANSS were lower in the prison hospital group (BPRS, 43.8 versus 51.2; PANSS, 71.5 versus 83.7). We assume that social disintegration for mentally disturbed offenders prior to incarceration hindered effective treatment. To avoid further social disintegration and possible further deterioration of mental health status of released offenders, which may lead to reoffending after imprisonment, discharge management after release from prison should be improved.     

A Predictive Approach to Nonparametric Inference for Adaptive Sequential Sampling of Psychophysical Experiments

We present a predictive account on adaptive sequential sampling of stimulus-response relations in psychophysical experiments. Our discussion applies to experimental situations with ordinal stimuli when there is only weak structural knowledge available such that parametric modeling is no option. By introducing a certain form of partial exchangeability, we successively develop a hierarchical Bayesian model based on a mixture of Pólya urn processes. Suitable utility measures permit us to optimize the overall experimental sampling process. We provide several measures that are either based on simple count statistics or more elaborate information theoretic quantities. The actual computation of information theoretic utilities often turns out to be infeasible. This is not the case with our sampling method, which relies on an efficient algorithm to compute exact solutions of our posterior predictions and utility measures. Finally, we demonstrate the advantages of our framework on a hypothetical sampling problem.     

Schematic influences of rape myth acceptance on visual information processing: An eye-tracking approach

Schematic influences of rape myth acceptance (RMA) on visual information processing were studied. After reading a short text on a rape case, students viewed a “police photograph” of the plaintiff's living room, where the rape allegedly happened, while their eye-movements were recorded. The photograph contained two myth-consistent cues, one being expected in the situation (wine bottle and glasses), the other unexpected (poster of a nude male). Results of Study 1 (N = 60) showed that participants higher in RMA fixated the expected cue both earlier and less long, which may indicate hypervigilance and greater ease of processing, respectively. Higher RMA also predicted longer initial fixation of the unexpected cue. These processing differences mediated participants' verdicts and blame judgments. In Study 2 (N = 30), participants' level of RMA was manipulated experimentally via social norm feedback. This manipulation significantly affected eye-movement patterns for the expected myth-consistent cue. Results support the notion that RMA actively guides visual information processing of relevant stimuli.
