Science and Art: physics as a symbolic formation

The reflection on the preconditions and evolution of science has played a decisive role in the development of Ernst Cassirer’s philosophy, contributing to its functional and thus inherently pluralistic and holistic view of knowledge. To present Cassirer’s conception of physics as an open symbolic formation enables us to reveal and study the radical features of his epistemological model:

Testing the effects of an expectancy-based intervention among adolescents: Can placebos be used to enhance physical health?

It has been suggested that the well-known health benefits associated with exercise can be explained by a placebo effect, and that greater effort should be given to convince people that their current behaviors have desirable health consequences. The overall purpose of this study was to test the efficacy of this "mind-set matters" hypothesis through the use of an expectancy-based intervention with adolescents. The study involved a four week randomized controlled trial with 348 Grade 9 adolescents (M (age)?=?14.07 yrs, SD?=?0.30), from four high schools, taking part in either a placebo-intervention condition (n?=?188) or a control condition (n?=?160). Participants in the placebo-intervention condition were informed that what they are already doing in school physical education lessons fulfills current recommendations for an active lifestyle. Participants in the control condition were not given this information. Four weeks after the intervention, adolescents in the placebo-intervention condition did not demonstrate significant changes in physiological health-related measures (diet, weight, body mass index, percentage body fat, heart rate, mean arterial pressure). The findings question the external validity of the "mind-set matters" hypothesis with adolescents, and suggest that simply encouraging adolescents to believe that they are healthy may not enable them to respond with improved indicators of physical health.     

The goal to be accepted by friends as underlying function of overt aggressive behaviour in immigrant adolescents

This study investigated (1) to what extent the goal to be accepted by friends is an underlying function of overt aggressive behavior in adolescents, and (2) whether this function is more predictive than reactive aggression for overt aggressive behavior in first and second generation immigrants compared with natives. The sample comprised 339 native Austrians (51.6% girls), 126 first generation immigrants (48.4% girls), and 175 second generation immigrants (54.3% girls) aged 14 to 19 (M = 15.61). Data were collected via self-assessments. Multiple group latent means and covariance structures (MACS) models revealed that the goal to be accepted by friends was a stronger predictor than reactive aggression for overt aggressive behavior in first generation immigrants compared with second generation immigrants and natives. Furthermore, gender moderated these associations. The goal to be accepted by friends was a very strong predictor of overt aggressive behavior in first generation immigrant boys, but not in first generation immigrant girls. Results are discussed regarding the process of acculturation in first generation immigrant youth.     

Depressive symptoms in native and immigrant adolescents: the role of critical life events and daily hassles

The present study compared native Austrian, first and second generation immigrant adolescents regarding their level of depressive symptoms, critical live events, and daily hassles. Furthermore, the associations between these constructs were tested in the three groups. The sample comprised 330 native Austrian (52.1% girls), 120 first generation immigrants (49.2% girls and 159 second generation immigrants (54.2% girls) aged 14-19 (M=15.61). Compared with native adolescents, first generation immigrant adolescents reported more depressive symptoms and daily hassles related to parents, the self, leisure, romantic partner, and future, whilst second generation immigrant adolescents reported more daily hassles related to parents, school, and romantic partner. Controlling for gender, multiple group structural equation models revealed that daily hassles fully mediated the path between critical live events and depressive symptoms in all three groups of adolescents. Implications for future research on immigrant adolescents' psychological well-being are discussed.     

Gender-specific contribution of a visual cognition network to reading abilities

Based on the assumption that boys are more likely to tackle reading based on the visual modality, we assessed reading skills, visual short-term memory (VSTM), visual long-term memory for details (VLTM-D), and general non-verbal cognitive ability in primary school children. Reading was within the normal range in both accuracy and understanding. There was no reading performance gap in favour of girls, on the contrary, in this sample boys read better. An entire array of visual, non-verbal processes was associated directly or indirectly with reading in boys, whereas this pattern was not observed for the girls.     

Less is more: the effects of very brief versus clearly visible exposure

This study compared the effects of exposure to masked and unmasked phobic stimuli on phobic behavior. Participants were identified as spider-phobic with a questionnaire and a Behavioral Avoidance Test (BAT) with a live tarantula (N = 101). One week later, they were administered one of three types of exposure: very brief (25 ms) or clearly visible (120 ms) images of spiders, or very brief images of flowers. They reported ratings of subjective distress just before and after these exposures, and engaged in the BAT again thereafter. Two weeks later, 57 participants returned for a follow-up BAT. The results indicated a double dissociation between the effects of very brief and clearly visible exposure: the former reduced avoidance of the tarantula and did not affect distress, whereas the latter increased distress but did not affect avoidance. The behavioral effect lasted for two weeks. These findings suggest that avoidance of a feared object can be reduced without full conscious awareness. The theoretical implications are discussed.     

Wandlerin zwischen den Welten

Anneliese Schnurmann belongs to the first generation of Anna Freud’s coworkers in the war nurseries and psycho-analytical child experts, as pediatric analytical training was called, which were established by Anna Freud. Although Anneliese Schnurmann later completed a training at the British Psychoanalytical Institute as an adult psychoanalyst, she remained a lifelong follower of Anna Freud’s concept. This might be due the fact that she had found a replacement homeland as had many emigrants from Germany and Austria in the circle around Anna Freud. Even during her time in Berlin, Anneliese Schnurmann, who was befriended with the Bonhoeffer family, established the “Jugendstube Charlottenburg” (Youth Home Charlottenburg) for unemployed youth, together with Dietrich Bonhoeffer.     

Genes and the parsing of cognitive processes

Now that the human genome has been sequenced there exists the possibility of identifying specific genes that affect human cognition. In this article, recent studies that have found associations between common gene variants and specific cognitive processes are reviewed. Several principles for evaluating this new field are also discussed. The interpretation of results is far from simple because a single gene can affect multiple processes, multiple genes can impact on a single process, and multiple cognitive processes are intercorrelated. In general, functional neuroimaging has been a more sensitive assay of cognitive processing than behavioral measures used alone, although there are important caveats regarding its use. Replicated findings so far involve associations between a COMT polymorphism and prefrontally-based executive functions and neurophysiology, and a BDNF polymorphism and medial-temporal-cortex based declarative memory processes. Implicit in this review is a concern that many of the cognitive paradigms used evolved for purposes well outside those described here. As such it may be necessary to view cognition in novel ways, based on constraints imposed by genomics and neurobiology, in order to increase the effect size of genotypic influences on cognition.     

Person—Situation Predictors of Maximum and Typical Performance

We examined the main and interactive effects of general mental ability (GMA) and perceived organizational support (POS) on typical performance and maximum performance. Data from two field samples (96 programmers and 181 cash vault employees) empirically supported distinguishing between typical performance and maximum performance. GMA was related to maximum performance but not to typical performance, and POS was related to two out of three measures of typical performance. Interactive effects of GMA and POS were detected in both samples for maximum performance outcomes but not found for typical performance outcomes.     

Psychotherapeuten und Internet

Background

Communication is part and parcel of every interaction. This raises the question of the role of modern media in mental health care. The aim of this explorative study was to investigate the use of modern media in the clinical practice.

Material and methodology

In an Internet survey 234 psychotherapists from Nordrhein-Westfalen (NRW) were surveyed about the extent to which they integrate new media in the practice and their opinion about this integration. For this purpose a questionnaire was developed based on the questionnaire of Wangberg et al. (2007).

Results

Most of the psychotherapists already use e-mails as well as mobile communication to contact their patients. The main reason for choosing this modern way of communication is the possibility to simplify the management of formal issues. Psychotherapists were indifferent about the idea of web-based counseling.

Conclusion

Forms of digital media are used as an addition to conventional ways of therapeutic communication but face-to-face interaction cannot be replaced completely which is also indicated by the fact that professionals still highly value personal contact.
