Internetbasierte Vorbereitung auf eine station?re psychosomatisch-psychotherapeutische Behandlung

Background

Encouraged by promising results of online aftercare programs, this study adapted the concept of internet-based minimal interventions in order to use the time between referral and actual admission to inpatient treatment. The online intervention includes information about the hospital and the treatment and sections which aim to enhance motivation, provide support and allow contact.

Methods

A comprehensive cohort study was conducted with 379 participants in the randomized subcohort. Primary endpoint was the speed of change of the physical, mental and social impairment and of the psychological well-being in the first 2 weeks of inpatient treatment as well as the rates of reliable change 2 weeks after admission.

Results

Both the control and intervention group of the randomized subcohort showed statistically significant improvements in health status. No significant difference in the rate of change was found. The degree of achieved improvement in the physical impairment was equal to the expected intervention effect. A difference in the rates of change was found for the psychological well-being: the intervention group showed 19% more reliable improvements.

Conclusions

The study design and the contents of the intervention were accepted by the patients. The internet-based intervention can help to prepare for treatment and to shorten the settling-in period.     

Category priming with aliens: analysing the influence of targets' prototypicality on the centre surround inhibition mechanism

Marginally perceptible prototypes as primes lead to slowed reactions to related category exemplars as compared to unrelated ones. This at first glance counterintuitive finding has been interpreted as evidence for a particular mechanism of lateral inhibition, namely the centre surround inhibition mechanism. We investigated the semantic surround of category labels by experimentally manipulating the prototypicality of stimuli. Participants first learned two new categories of fantasy creatures in a 5-day-long learning phase before they worked through a semantic priming task with the category prototypes as primes and category exemplars as targets. For high-prototypical targets we observed benefit effects from related primes, whereas for low-prototypical targets we observed cost effects. The results define when the centre surround inhibition mechanism is applied, and furthermore might explain why previous studies with word stimuli (i.e., material that prevents experimental manipulation of prototypicality) observed mixed results concerning the prototypicality of targets.     

On the positive aspects of customers: Customer‐initiated support and affective crossover in employee–customer dyads

This study examines psychological resources for service employees and their customers, which enhance the service experiences of both parties during service conversations. We investigate whether customer behaviour (customer‐initiated support) positively impacts on employees’ affect. We also examine the crossover of employees’ affect on customers’ affect. State positive affect (PA) was assessed in 82 employees of car dealerships and 421 customers on 2 occasions (before and after the conversation). Multi‐level analyses showed the hypothesized positive impact of customer behaviour on employees’ PA and in turn of employees’ PA on customers’ PA. Results are integrated in an overall process model whereby customers’ PA leads to customer‐initiated support, which increases employees’ PA and in turn enhances customers’ PA. Results suggest direct and indirect crossover effects. This study extends research on customer behaviour offering a positive slant on customer behaviour and suggests to actively involve customers in the service process in order to promote their positive behaviour towards employees.     

Nanomaterials and the environmental risk: is there some room left for ethics and law?

How legitimate may be the concern posed by the nanotechnologies for health and environment,this effort for reaching a better knowledge of the biotoxicity of nanomaterials is not enough. As Pr Didier Sicard noted, we believe that the ethical reflection should not be the good conscience that may help science in getting rid of social fears. But the ethical reflection is there also to discuss taboo issues in the perspective of a better societal understanding.     

Contemplative Pedagogy: Frequently Asked Questions

Contemplative Pedagogy is a new and sometimes controversial pedagogical practice. Faculty often have basic questions about how to implement the pedagogy in their classrooms, in addition to questions that challenge the educational value and appropriateness of the practice. Assembled here are the most frequently asked questions about Contemplative Pedagogy, with responses from six contemplative professors, each from a different institutional and philosophical location. The respondents are founding members of the Contemplative Studies Consultation of the American Academy of Religion. The diversity of views expressed by the respondents invites the reader to see that there is no single theory or praxis of contemplative pedagogy.     

Poetry as anti-discourse: formalism,hermeneutics, and the poetics of Paul Celan

I argue from a hermeneutic point of view that formal elements of poetry can only be identified because poetry is based on both the phenomenon and the conception of poetry, both of which precede the attempt to identify formal elements as the defining moment of poetry. Furthermore, I argue with Gadamer that poetry is based on a rupture with and an epoche of our non-poetic use of language in such a way that it liberates “fixed” universal aspects of everyday language, and that through establishing itself in a new, self-referential and monologue unity, it individualizes speech. From the hermeneutic position, poetry is a form of speaking rather than a “fixed” object. As such, I will try to make sense of what Paul Celan said in his famous “Meridian” speech: namely, that the poem is “actualized language, set free under the sign of a radical individuation, which at the same time stays mindful of the limits drawn by language, the possibilities opened by language.”     

The nicotinic acetylcholine receptor gene CHRNA4 is associated with negative emotionality

Knock-out studies in mice suggest a role of the CHRNA4 gene in anxiety. In the present study we extend this finding to humans by means of a genetic association study. In a sample of N = 574 healthy White participants, the CHRNA4 rs1044396 polymorphism is related to the common variance of several conceptualizations of negative emotionality. Compared to carriers of at least one T-allele, carriers of the homozygous C/C genotype described themselves as more anxious and emotionally unstable on various psychometric personality questionnaires. The scope of the genetic effect is remarkable because other prominent genetic markers for anxiety show specificity for the diagnostic tool used. The present study is the first study that demonstrates the relevance of the CHRNA4 gene for negative emotionality in humans and sets a starting point for further investigations that could inform on the treatment of various affective psychiatric disorders.     

The effect of induced anxiety on cognition: threat of shock enhances aversive processing in healthy individuals

Individuals with anxiety disorders demonstrate altered cognitive performance including (1) cognitive biases towards negative stimuli (affective biases) and (2) increased cognitive rigidity (e.g., impaired conflict adaptation) on affective Stroop tasks. Threat of electric shock is frequently used to induce anxiety in healthy individuals, but the extent to which this manipulation mimics the cognitive impairment seen in anxiety disorders is unclear. In this study, 31 healthy individuals completed an affective Stroop task under safe and threat-of-shock conditions. We showed that threat (1) enhanced aversive processing and abolished a positive affective bias but (2) had no effect on conflict adaptation. Threat of shock thus partially models the effects of anxiety disorders on affective Stroop tasks. We suggest that the affective state of anxiety—which is common to both threat and anxiety disorders—modulates the neural inhibition of subcortical aversive processing, whilst pathologies unique to anxiety disorders modulate conflict adaptation.     

Motor planning and execution in left- and right-handed individuals during a bimanual grasping and placing task

The issue of handedness has been the topic of great interest for researchers in a number of scientific domains. It is typically observed that the dominant hand yields numerous behavioral advantages over the non-dominant hand during unimanual tasks, which provides evidence of hemispheric specialization. In contrast to advantages for the dominant hand during motor execution, recent research has demonstrated that the right hand has advantages during motor planning (regardless of handedness), indicating that motor planning is a specialized function of the left hemisphere. In the present study we explored hemispheric advantages in motor planning and execution in left- and right-handed individuals during a bimanual grasping and placing task. Replicating previous findings, both motor planning and execution was influenced by object end-orientation congruency. In addition, although motor planning (i.e., end-state comfort) was not influenced by hand or handedness, motor execution differed between left and right hand, with shorter object transport times observed for the left hand, regardless of handedness. These results demonstrate that the hemispheric advantages often observed in unimanual tasks do not extend to discrete bimanual tasks. We propose that the differences in object transport time between the two hands arise from overt shifting visual fixation between the two hands/objects.
