The limbic system and especially the amygdala have been identified as key structures in emotion induction and regulation. Recently research has additionally focused on the influence of prefrontal areas on emotion processing in the limbic system and the amygdala. Results from fMRI studies indicate that the prefrontal cortex (PFC) is involved not only in emotion induction but also in emotion regulation. However, studies using fNIRS only report prefrontal brain activation during emotion induction. So far it lacks the attempt to compare emotion induction and emotion regulation with regard to prefrontal activation measured with fNIRS, to exclude the possibility that the reported prefrontal brain activation in fNIRS studies are mainly caused by automatic emotion regulation processes. Therefore this work tried to distinguish emotion induction from regulation via fNIRS of the prefrontal cortex. 20 healthy women viewed neutral pictures as a baseline condition, fearful pictures as induction condition and reappraised fearful pictures as regulation condition in randomized order. As predicted, the view-fearful condition led to higher arousal ratings than the view-neutral condition with the reappraise-fearful condition in between. For the fNIRS results the induction condition showed an activation of the bilateral PFC compared to the baseline condition (viewing neutral). The regulation condition showed an activation only of the left PFC compared to the baseline condition, although the direct comparison between induction and regulation condition revealed no significant difference in brain activation. Therefore our study underscores the results of previous fNIRS studies showing prefrontal brain activation during emotion induction and rejects the hypothesis that this prefrontal brain activation might only be a result of automatic emotion regulation processes.

The aims of this study are to assess patients’ preferred and perceived decision-making roles and preference matching in a sample of German breast and colon cancer patients and to investigate how a shared decision-making (SDM) intervention for oncologists influences patients’ preferred and perceived decision-making roles and the attainment of preference matches. This study is a post hoc analysis of a randomised controlled trial (RCT) on the effects of an SDM intervention. The SDM intervention was a 12-h SDM training program for physicians in combination with decision board use. For this study, we analysed a subgroup of 107 breast and colon cancer patients faced with serious treatment decisions who provided data on specific questionnaires with regard to their preferred and perceived decision-making roles (passive, SDM or active). Patients filled in questionnaires immediately following a decision-relevant consultation (t1) with their oncologist. Eleven of these patients’ 27 treating oncologists had received the SDM intervention within the RCT. A majority of cancer patients (60%) preferred SDM. A match between preferred and perceived decision-making roles was reached for 72% of patients. The patients treated by SDM-trained physicians perceived greater autonomy in their decision making (p < 0.05) with more patients perceiving SDM or an active role, but their preference matching was not influenced. A SDM intervention for oncologists boosted patient autonomy but did not improve preference matching. This highlights the already well-known reluctance of physicians to engage in explicit role clarification.Trial Registration: German Clinical Trials Register DRKS00000539; Funding Source: German Cancer Aid.

• " physician-patient-interaction Abstract !The article provides an overview on Shared Decision Making (SDM), which is considered as the ideal form of physician-patient-interaction by many stakeholders of the health care system. SDM is distinguished from other models of physician-patient-interaction such as the paternalistic model and the information model. Besides the degree of acceptance of SDM in the general population and among physicians, barriers for its implementation will be reported. Indications for SDM as well as strategies and support material for its use in individual consultations will be discussed and illustrated by an oncological case study. Effects of SDM for patients as well as for clinicians will be highlighted. After background information on origins of SDM, its significance with regard to health policy in Germany is discussed.

The catechol-O-methyltransferase (COMT) Val158Met polymorphism (rs4680) moderates dopamine degradation in the prefrontal cortex. It has been shown that the Met allele is associated with an increased reactivity to negative stimuli. With regard to the tonic-phasic dopamine model it is hypothesized that this increased reactivity to negative stimuli derives from deficient disengagement from negative stimuli. The aim of this study was therefore to investigate whether this increased reactivity is reflected in prolonged disengagement from negative pictures. We used a novel forced spatial disengagement task in combination with eye tracking. This paradigm allows for varying task difficulty. Interestingly, contrary to our hypothesis, we found increased disengagement latencies for negative pictures in homozygous Val allele carriers compared to heterozygous participants. This effect was only seen in task conditions demanding less cognitive resources (prosaccade condition). We suggest that the COMT effect on emotional processing is task-specific and therefore heterosis effects can occur.
