Parental rearing behavior prospectively predicts adolescents’ risky decision‐making and feedback‐related electrical brain activity

The present study examined the role of parental rearing behavior in adolescents’ risky decision‐making and the brain's feedback processing mechanisms. Healthy adolescent participants (n = 110) completed the EMBU‐C, a self‐report questionnaire on perceived parental rearing behaviors between 2006 and 2008 (T1). Subsequently, after an average of 3.5 years, we assessed (a) risky decision‐making during performance of the Balloon Analogue Risk Task (BART); (b) event‐related brain potentials (ERPs) elicited by positive (gain) and negative feedback (loss) during the BART; and (c) self‐reported substance use behavior (T2). Age‐corrected regression analyses showed that parental rejection at T1 accounted for a unique and significant proportion of the variance in risk‐taking during the BART; the more adolescents perceived their parents as rejecting, the more risky decisions were made. Higher levels of perceived emotional warmth predicted increased P300 amplitudes in response to positive feedback at T2. Moreover, these larger P300 amplitudes (gain) significantly predicted risky decision‐making during the BART. Parental rearing behaviors during childhood thus seem to be significant predictors of both behavioral and electrophysiological indices of risky decision‐making in adolescence several years later. This is in keeping with the notion that environmental factors such as parental rearing are important in explaining adolescents’ risk‐taking propensities.     

Humor Types Show Different Patterns of Self-Regulation, Self-Esteem, and Well-Being

Humor styles have been found to be associated with well-being, however, no study has addressed the distinct well-being associations of combinations of humor styles, that is, humor types, yet. The present study thus aimed at investigating which combinations of humor styles exist and to which extent these humor types are associated with well-being. In an online questionnaire, the Humor Styles Questionnaire (HSQ, Martin et al. J Res Pers 37:48–75, 2003), self-regulatory strategies, self-esteem, and well-being instruments were administered to a German sample. Exploratory and confirmatory factor analyses replicated the underlying structure of the HSQ. With hierarchical clustering, we found evidence for three humor types (endorsers, humor deniers, and self-enhancers), which differed in group means for self-esteem, self-regulatory strategies, and well-being. Findings provide further evidence for the positive well-being correlates of self-enhancing humor, and distinctly address the positive correlates of aggressive and self-defeating humor being absent. It is discussed that humor styles cannot be conceptualized as beneficial or detrimental per se, but have to be regarded in context.     

Non-Local Correlations in Therapeutic Settings? A Qualitative Study on the Basis of Weak Quantum Theory and the Model of Pragmatic Information

Weak Quantum Theory (WQT) and the Model of Pragmatic Information (MPI) are two psychophysical concepts developed on the basis of quantum physics. The present study contributes to their empirical examination. The issue of the study is whether WQT and MPI can not only explain ‘psi’-phenomena theoretically but also prove to be consistent with the empirical phenomenology of extrasensory perception (ESP). From the main statements of both models, 33 deductions for psychic readings are derived. Psychic readings are defined as settings, in which psychics support or counsel clients by using information not mediated through the five senses. A qualitative approach is chosen to explore how the psychics experience extrasensory perceptions. Eight psychics are interviewed with a half-structured method. The reports are examined regarding deductive and inductive aspects, using a multi-level structured content analysis. The vast majority of deductions is clearly confirmed by the reports. Even though the study has to be seen as an explorative attempt with many aspects to be specified, WQT and MPI prove to be coherent and helpful concepts to explain ESP in psychic readings.     

Sinnorientierte Interventionen in der Psychoonkologie

Patients with advanced cancer often suffer from existential distress. Although a variety of effective psychotherapeutic interventions for the treatment of psychological distress in cancer patients are available, concerns such as hope and meaning of life are only occasionally at the center of therapeutic attention. During recent years growing efforts have been made to develop and evaluate meaning-based interventions for cancer patients, particularly in the Anglo-American research literature. Meaning-based interventions are often realized as group therapy approaches to reduce emotional and spiritual distress and to promote hope, courage and control, to mobilize internal resources and to discuss future goals despite a noticeable limited life expectancy. Further aims include strengthening a patient??s self-esteem and sense of dignity, to appreciate strengths and past achievements, to reduce feelings of isolation, to strengthen the relationship with the partner and family members and to improve communication with the professional healthcare team.     

The influence of dichotical fusion on the redundant signals effect,localization performance,and the mismatch negativity

In two experiments, each including a simple reaction time (RT) task, a localization task, and a passive oddball paradigm, the physical similarity between two dichotically presented auditory stimuli was manipulated. In both experiments, a redundant signals effect (RSE), high localization performance, and a reliable mismatch negativity (MMN) was observed for largely differing stimuli, suggesting that these are coded separately in auditory memory. In contrast, no RSE and a localization rate close to chance level (experiment 1) or at chance (experiment 2) were observed for stimuli differing to a lesser degree. Crucially, for such stimuli a small (experiment 1) or no (experiment 2) MMN were observed. These MMN results indicate that such stimuli tend to fuse into a single percept and that this fusion occurs rather early within information processing.     

Chronic psychosocial stress increases the risk for inflammation-related colon carcinogenesis in male mice

Patients with inflammatory bowel diseases (IBDs) have a higher risk of developing colorectal cancer (CRC) than the general population. Furthermore, chronic psychosocial stress increases the likelihood of developing IBD and multiple types of malignant neoplasms, including CRC. Here, for the first time, we investigate the effects of chronic psychosocial stress in male mice on an artificially induced CRC, by employing the chronic subordinate colony (CSC) housing paradigm in combination with the reliable azoxymethane (AOM)/dextran sodium sulfate (DSS) CRC model. Colonoscopy revealed that CSC mice showed accelerated macroscopic suspect lesions. In addition, more CSC mice developed low-grade dysplasia (LGD) and/or high-grade dysplasia (HGD) in the colonic tissue compared to the single-housed control mice (SHC). CSC mice showed an increased number of Ki67+ and a decreased number of terminal deoxynucleotidyl transferase dUTP nick end labeling epithelial cells in colonic tissue. Colonic liver receptor homolog-1 (LRH-1), cyclooxygenase II (COXII), tumor necrosis factor, forkhead box P3 (FoxP3) mRNA as well as colonic ?-catenin, COXII, and LRH-1 protein expression were also increased in CSC compared with SHC mice. Although the number of CD4+ Th cells was increased, a tendency toward a decreased colonic interferon-γ (IFN-γ) mRNA expression was observed. Furthermore, despite an increased percentage of CD3+ cells and CD3+/FoxP3+ double-positive cells within mesenteric lymph node cells of CSC mice, IFN-γ secretion from these cells was unaffected. Altogether, our results suggest that chronic psychosocial stress increases the risk for AOM/DSS-induced and, thus, inflammation-related CRC. Finally, assessment of additional time points may test whether the shift from tumor-protective Th1 cell to regulatory T-cell immunity represents a consequence of increased carcinogenesis or a causal factor involved in its development.
