Standards nichtstrafrechtlicher psychiatrischer Begutachtung

The introduction of the certificate for forensic psychiatry of the German Association of Psychiatry, Psychotherapy, Psychosomatics (DGPPN) in 2000 was a significant contribution to raising awareness of the formal and substantive requirements for forensic psychiatric evaluations and to develop a systematic quality improvement in forensic psychiatric expert services. By the special dominance of the certification in the field of penal law assessment, this proved to be problematic for many predominantly non-penal experts. This led to a requirement to develop a qualification for the non-penal expert opinions. In particular the increasing specialization of the psychiatric disciplines and the diversity of the legal issues and framework require a continuing education in the field of non-penal psychiatric assessments. Substantive and formal requirements are discussed and a continuous process of quality improvement and assurance is outlined. Last but not least a plea is made for close interdisciplinary exchange with the jurisprudence and the courts in the context of quality circles.     

Sensory memory of illusory depth in structure-from-motion

When multistable displays (stimuli consistent with two or more equally plausible perceptual interpretations) are presented intermittently, their perceptions are stabilized by sensory memory. Independent memory traces are generated not only for different types of multistable displays (Maier, Wilke, Logothetis, & Leopold, Current Biology 13:1076–1085, 2003), but also for different ambiguous features of binocular rivalry (Pearson & Clifford, Journal of Vision 4:196–202, 2004). In the present study, we examined whether a similar independence of sensory memories is observed in structure-from-motion (SFM), a multistable display with two ambiguous properties. In SFM, a 2-D planar motion creates a vivid impression of a rotating 3-D volume. Both the illusory rotation and illusory depth (i.e., how close parts of an object appear to the observer) of an SFM object are ambiguous. We dissociated the sensory memories of these two ambiguous properties by using an intermittent presentation in combination with a forced-ambiguous-switch paradigm (Pastukhov, Vonau, & Braun, PLoS ONE 7:e37734, 2012). We demonstrated that the illusory depth of SFM generates a sensory memory trace that is independent from that of illusory rotation. Despite this independence, the specificities levels of the sensory memories were identical for illusory depth and illusory rotation. The history effect was weakened by a change in the volumetric property of a shape (whether it was a hollow band or a filled drum volume), but not by changes in color or size. We discuss how these new results constrain models of sensory memory and SFM processing.     

Perceived sources and levels of stress,general self-efficacy and coping strategies in preclinical dental students

Dental education programs are known to be highly stressful and stress can affect general health. The aims were to identify sources of stress among preclinical students and to evaluate their perceived levels of stress, self-efficacy and effective coping strategies in a private dental school. One hundred preclinical students in a Turkish private dental school were surveyed using dental environment stress (DES), perceived stress (PSS), general self-efficacy (G-SES) and brief coping scales (Brief-COPE). Age, gender, history of psychiatric treatment, factors that affected the choice of dentistry, choice rank of dental school, scholarship and income was recorded. ‘Exams and grades’ followed by ‘Fear of failing course or year’ were found to be the most stressprovoking factors. The most and the least stressprovoking DES domains were ‘Workload’ and ‘Social stressors’, respectively. ‘Social stressors’ affected male more than female (p < .05). The most and the least common coping strategies were found to be ‘Planning’, and ‘Drug’, respectively. Female used ‘Instrumental support’ more than male (p < .05). Demographic factors had impact on the perceived stress factors and levels, as well as coping strategies. Unlike previous studies establishing high stress levels in dental students, preclinical students displayed moderate level of stress. Clinical dental education might be more responsible for creating stress.     

Alternative death rituals in Switzerland: building a community of shared emotions and practices

New alternative death rituals are gaining significance in Switzerland, like in other contemporary Western societies. This article discusses how celebrants who are independent of any religious community shape alternative funerals and why such rituals may be able to function as a coping resource for a certain kind of participants. I argue that these rituals, co-produced by celebrants and the bereaved and including actively involved participants, can be seen as a re-conquest of ritual agency for lay people. By encouraging physical and mental contact with the deceased, the celebrants try to enable emotional arousal and create a temporary community of shared experiences and emotions and of the living and the dead. Elements of an individually crafted spirituality and a kind of nature religion represent both separation and continuing bonds between the living and the dead. As a consequence, such funerals serve as a resource in the face of death by integrating a singular death with the wider context.     

Mediating and Moderating Effects of Social Support in the Relationship Between Social Anxiety and Hope Levels in Children

This study aims to examine whether hope levels are predicted by social anxiety and social support and to investigate if the relationship between social anxiety and children’s hope levels is mediated and moderated by the social support of children. The Social Anxiety Scale for Children, Children’s Hope Scale, and Social Support Appraisals Scale for Children were administrated to a sample of 289 children (148 males and 141 females) enrolled in public school. To determine the relationships between variables, a Pearson correlation coefficient was utilized. Regression-based mediation and moderation analyses assessed whether social support mediates and moderates the relationship between social anxiety and children’s hope levels. Social anxiety and social support both correlated significantly with children’s hope levels; social anxiety had a negative correlation with children’s hope levels, while social support was positively correlated. Regression-based mediation and moderation analyses showed that social support mediates and moderates the relationship between social anxiety and children’s hope levels. The results of the present study emphasized the effects of social support on children; it had a positive effect on hope levels and a negative effect on social anxiety. Based on these results, it is recommended that the social support of children is increased via psycho-education programs for parents, caregivers, and teachers. It is further recommended that social-support-seeking behavior programs are developed in educational and mental health settings.     

Interspecies transmission of emotional information via chemosignals: from humans to dogs (<Emphasis Type="Italic">Canis lupus familiaris</Emphasis>)

We report a study examining interspecies emotion transfer via body odors (chemosignals). Do human body odors (chemosignals) produced under emotional conditions of happiness and fear provide information that is detectable by pet dogs (Labrador and Golden retrievers)? The odor samples were collected from the axilla of male donors not involved in the main experiment. The experimental setup involved the co-presence of the dog’s owner, a stranger and the odor dispenser in a space where the dogs could move freely. There were three odor conditions [fear, happiness, and control (no sweat)] to which the dogs were assigned randomly. The dependent variables were the relevant behaviors of the dogs (e.g., approaching, interacting and gazing) directed to the three targets (owner, stranger, sweat dispenser) aside from the dogs’ stress and heart rate indicators. The results indicated with high accuracy that the dogs manifested the predicted behaviors in the three conditions. There were fewer and shorter owner directed behaviors and more stranger directed behaviors when they were in the “happy odor condition” compared to the fear odor and control conditions. In the fear odor condition, they displayed more stressful behaviors. The heart rate data in the control and happy conditions were significantly lower than in the fear condition. Our findings suggest that interspecies emotional communication is facilitated by chemosignals.     

Eye blink detection for different driver states in conditionally automated driving and manual driving using EOG and a driver camera

In this article, we examine the performance of different eye blink detection algorithms under various constraints. The goal of the present study was to evaluate the performance of an electrooculogram- and camera-based blink detection process in both manually and conditionally automated driving phases. A further comparison between alert and drowsy drivers was performed in order to evaluate the impact of drowsiness on the performance of blink detection algorithms in both driving modes. Data snippets from 14 monotonous manually driven sessions (mean 2 h 46 min) and 16 monotonous conditionally automated driven sessions (mean 2 h 45 min) were used. In addition to comparing two data-sampling frequencies for the electrooculogram measures (50 vs. 25 Hz) and four different signal-processing algorithms for the camera videos, we compared the blink detection performance of 24 reference groups. The analysis of the videos was based on very detailed definitions of eyelid closure events. The correct detection rates for the alert and manual driving phases (maximum 94%) decreased significantly in the drowsy (minus 2% or more) and conditionally automated (minus 9% or more) phases. Blinking behavior is therefore significantly impacted by drowsiness as well as by automated driving, resulting in less accurate blink detection.     

Reappraisal inventiveness: impact of appropriate brain activation during efforts to generate alternative appraisals on the perception of chronic stress in women*

Background and objectives: Previous research indicated that more left-lateralized prefrontal activation during cognitive reappraisal efforts was linked to a greater capacity for generating reappraisals, which is a prerequisite for the effective implementation of cognitive reappraisal in everyday life. The present study examined whether the supposedly appropriate brain activation is relevant in terms of more distal outcomes, i.e., chronic stress perception.

Design and methods: Prefrontal EEG alpha asymmetry was recorded while female participants were generating reappraisals for stressful events and was correlated with their self-reported chronic stress levels in everyday life (n?=?80).

Results: Women showing less left-lateralized brain activity in the ventrolateral prefrontal cortex during cognitive reappraisal efforts reported experiencing more stress in their daily lives. This effect was independent of self-efficacy beliefs in managing negative emotions.

Conclusion: These findings underline the practical relevance of individual differences in appropriate brain activation during emotion regulation efforts and the assumedly related basic capacity for the generation of cognitive reappraisals to the feeling of being stressed. Implications include the selection of interventions for the improvement of coping with stress in women in whom the capability for appropriate brain activation during reappraisal efforts may be impaired, e.g., due to depression or old age.
