Parents' education and children's achievement: The role of personality

The reasons for the positive association between families' background variables, such as parents' education, and children's academic achievement have not fully been clarified yet. The present study investigates children's intelligence and personality as potential mediators. A sample of 580 German high school students (mean age: M = 17.0; SD = 0.7) indicated the highest education of their parents and completed measures assessing their own personality and intelligence. Children's academic achievement was operationalized by grade point average. Children's intelligence, openness to experience and, marginally, conscientiousness partially mediated the association between parents' education and children's academic achievement. Even after controlling for children's intelligence, the mediating effects of those personality traits held. Results are discussed with regard to potential underlying processes.

A randomized controlled trial of Internet-based self-help training for recurrent headache in childhood and adolescence

Two different self-help training programs (multimodal cognitive-behavioral training (CBT) and applied relaxation (AR)) presented via the Internet were compared with an educational intervention (EDU) in an RCT. Sixty-five children and adolescents (mean age: 12.7 years) with recurrent headache (at least 2 attacks per month) were each assigned to one of the three treatment conditions. The main outcome variables related to changes in headache frequency, intensity and duration as well as the responder rate (50% reduction of headache frequency) and NNTs. Secondary outcome variables were pain catastrophizing and general well-being (depression, psychopathological symptoms and health-related quality of life). All groups showed significant reduction in headache frequency, duration and pain catastrophizing, but not in headache intensity, depression, psychopathological symptoms or health-related quality of life at post-assessment. NNTs were 2.0 for the comparison CBT and EDU; 5.2 for the comparison of AR and EDU at post-treatment. The highest responder rates at post were from CBT (63%), significantly different compared to AR (32%) and EDU (19%), whereas at follow-up no significant differences were found (CBT: 63%, AR: 56%, EDU: 55%) reflecting in the NNTs.The effects remain stable in headache frequency, pain catastrophizing and psychopathological symptoms across all groups at follow-up assessment. CBT showed the highest within-effect size in headache frequency, duration and pain catastrophizing. The results support the use of Internet programs for pediatric recurrent headache, especially given their accessibility and suitability for children and adolescents. Further studies are needed to improve their quality and efficacy.     

Subjective randomness and natural scene statistics

Accounts of subjective randomness suggest that people consider a stimulus random when they cannot detect any regularities characterizing the structure of that stimulus. We explored the possibility that the regularities people detect are shaped by the statistics of their natural environment. We did this by testing the hypothesis that people’s perception of randomness in two-dimensional binary arrays (images with two levels of intensity) is inversely related to the probability with which the array’s pattern would be encountered in nature. We estimated natural scene probabilities for small binary arrays by tabulating the frequencies with which each pattern of cell values appears. We then conducted an experiment in which we collected human randomness judgments. The results show an inverse relationship between people’s perceived randomness of an array pattern and the probability of the pattern appearing in nature.     

How elevated blood alcohol concentration level and identification format affect eyewitness memory: A field study

Research shows that alcohol has a small and inconsistent effect on eyewitness recall and no effect on witnesses' lineup decisions. Much of this literature has tested participants with low‐to‐moderate blood alcohol concentration (BAC) levels, and no study has directly examined how identification procedure impacts intoxicated witnesses' decisions. In the present study, bar patrons' (N = 132) BAC levels were recorded before participating in a task. Midway through the task, they were interrupted by an intruder. Participants then recalled the incident via a staged interview and attempted to identify the intruder from a target‐present or target‐absent showup or lineup. Although elevated BAC levels (high as 0.24%) reduced the quantity and quality of information provided, BAC had no effect on witnesses' identification decisions regardless of format. Results highlight the importance of testing witness memory across a broad BAC spectrum and provide evidence that alcohol does not affect witnesses' identification ability.     

Psychotropic medication from an object relations theory perspective: an analysis of vignettes from group psychotherapy

In this article we explore the content and dynamics of patients' verbalizations within a "living with medications" group. Patients' perceptions of their psychotropic medications are interpreted and classified within the framework of object relations theory. One's perception of the role of medication in one's life can serve as a gateway to one's inner world and the way that he or she perceives authority figures, peers, and oneself. We suggest that working through patients' relationships with their medications can help them to achieve better integration of internal object relations. Discussing patients' views about medications should therefore be seen as an important part of psychotherapy with many individuals. Such a discussion may enhance and improve efficacy of both psychotherapy and pharmacotherapy. It is of particular importance in group therapy, within milieu environments and with individuals reluctant to explicitly discuss interpersonal matters. Vignettes from the group sessions illustrate the way in which discussing medication advances group process.     

Somatoforme Störungen bei ambulanten dermatologischen Patienten

Zusammenfassung In der vorliegenden Studie wurde die Häufigkeit somatoformer Symptome in einer dermatologischen Universitätsambulanz untersucht. An der Studie nahmen n=195 Patienten teil, die Screeningfragen zu somatoformen, dermatologischen und depressiven Symptomen ausfüllten. Zusätzlich wurde eine dermatologische Beurteilung der Symptome hinsichtlich der Ätiologie erfasst. Danach wiesen 26,2% der Patienten Hinweise auf eine somatoforme Störung auf; am häufigsten waren somatoforme Schmerzstörung (16,9%) und körperdysmorphe Störung (15,4%). Unter den spezifischen dermatologischen Symptomen wurde Juckreiz besonders häufig (10,3%) als somatoform klassifiziert. Der Anteil von Patienten mit erhöhten depressiven Beschwerden lag bei 17,3%. Die Ergebnisse sprechen für eine erhöhte Prävalenz somatoformer Störungen bei dermatologischen Patienten. Die Identifizierung und psychotherapeutische Versorgung dieser Patientengruppe sollte in der dermatologischen Routineversorgung mehr Beachtung finden.     

Prior beliefs and methodological concepts in scientific reasoning

This investigation focuses on the relations between prior beliefs, methodological concepts, and college students' (N=211) scientific reasoning in different problem contexts. Participants were presented with exercises that described the method and results of experiments, and were asked to draw conclusions about the causal status of variables that violated their prior beliefs. Participants drew conclusions in both abstract (i.e. recommend a conclusion for the fictional experimenter), and personal settings (i.e. draw their own conclusions about the phenomenon). Participants' recommendations for the hypothetical experimenter were predicted by their understanding of two methodological concepts: the function of empirical evidence and experimental control. Students' personal conclusions were predicted by their prior beliefs and their appreciation of the objectivity of inquiry. Thus, even when students understand in the abstract how data should relate to scientific conclusions, prior beliefs often take precedence in their own conclusions, especially when they do not understand the issue of objectivity.
