AbstractClinical motor and non-motor effects of deep brain stimulation (DBS) of the subthalamic nucleus (STN) in Parkinson's disease (PD) seem to depend on the stimulation site within the STN. We analysed the effects of the position of the stimulation electrode within the motor STN on subjective emotional experience, expressed as emotional valence and arousal ratings to pictures representing primary rewards and aversive fearful stimuli in 20 PD patients. Patients’ ratings from both aversive and erotic stimuli matched the mean ratings from a group of 20 control subjects at similar position within the STN. Patients with electrodes located more posteriorly reported both valence and arousal ratings from both the rewarding and aversive pictures as more extreme. Moreover, posterior electrode positions were associated with a higher occurrence of depression at a long-term follow-up. This brain–behavior relationship suggests a complex emotion topography in the motor part of the STN. Both valence and arousal representations overlapped and were uniformly arranged anterior-posteriorly in a gradient-like manner, suggesting a specific spatial organization needed for the coding of the motivational salience of the stimuli. This finding is relevant for our understanding of neuropsychiatric side effects in STN DBS and potentially for optimal electrode placement.

Valence And Arousal

Emotion recognition is a highly noteworthy and challenging work in both cognitive science and affective computing. Currently, neurobiology studies have revealed the partially synchronous oscillating phenomenon within brain, which needs to be analyzed from oscillatory synchronization. This combination of oscillations and synchronism is worthy of further exploration to achieve inspiring learning of the emotion recognition models. In this paper, we propose a novel approach of valence and arousal-based emotion recognition using EEG data. First, we construct the emotional oscillatory brain network (EOBN) inspired by the partially synchronous oscillating phenomenon for emotional valence and arousal. And then, a coefficient of variation and Welch’s [Formula: see text]-test based feature selection method is used to identify the core pattern (cEOBN) within EOBN for different emotional dimensions. Finally, an emotional recognition model (ERM) is built by combining cEOBN-inspired information obtained in the above process and different classifiers. The proposed approach can combine oscillation and synchronization characteristics of multi-channel EEG signals for recognizing different emotional states under the valence and arousal dimensions. The cEOBN-based inspired information can effectively reduce the dimensionality of the data. The experimental results show that the previous method can be used to detect affective state at a reasonable level of accuracy.

Zygomaticus Major

Images of pleasant scenes usually produce increased activity over the zygomaticus major muscle, as measured by electromyography (EMG), while less activity is elicited by unpleasant images. However, increases in zygomaticus major EMG activity while viewing unpleasant images have occasionally been reported in the literature on affective facial expression (i.e., “grimacing”). To examine the possibility that individual differences in emotion regulation might be responsible for this inconsistently observed phenomenon, the habitual emotion regulation tendencies of 63 participants (32 women) were assessed and categorized according to their regulatory tendencies. Participants viewed emotionally salient images while zygomaticus major EMG activity was recorded. Participants also provided self-report ratings of their experienced emotional valence and arousal while viewing the pictures. Despite demonstrating intact affective ratings, the “grimacing” pattern of zygomaticus major activity was observed in those who were less likely to use the cognitive reappraisal strategy to regulate their emotions.

Specific Number

This study investigated the temporal dynamics of emotional and cognitive processing underlying decision-making in moral judgment. Thirty-seven participants were presented with a set of 60 dilemmas varying in whether killing one individual was an intended means to save others (instrumental dilemmas) or a foreseen but unintended consequence (incidental dilemmas). Participants were required to decide between Options A (letting a specific number of people die) and B (killing one person to save a specific number of people). ERPs were recorded to a slide displaying the letters A and B while subjects were deciding between the options, and movement-related potentials were recorded time-locked to the behavioral response, thus allowing the investigation of both stimulus- and response-related processes during decision-making. Ratings of emotional valence and arousal experienced during decision-making were collected after each decision. Compared with incidental dilemmas, instrumental dilemmas prompted a lower number of B choices and significantly more unpleasant decisions. A larger P260 component was found in the frontopolar and frontal areas when subjects were deciding on instrumental than incidental dilemmas, possibly reflecting an immediate affective reaction during the early stage of assessment and formation of preferences between available options. On the other hand, decisions on incidental dilemmas required greater attentional resources during the fairly controlled later processing, as reflected in the larger slow wave amplitudes. In addition, facilitation of action selection and implementation was found for incidental dilemmas during the second stage of decision-making, as supported by the larger amplitudes of both components of the Bereitschaftspotential.

Emotion Concepts

ABSTRACTTwo major semantic features of emotion concepts have been shown to impact performance in emotion perception tasks: valence and arousal. To design psycholinguistic experiments with emotion terms as stimuli, norms are required that indicate valence and arousal values for individual words. Although such norms are usually obtained from ratings of adults, they are often also used in developmental studies. This procedure raises the question of whether children and adults perceive emotional valence and arousal of words in the same way, and consequently, whether adults’ ratings are adequate when constructing stimulus sets for children. The present study obtained valence and arousal ratings for 48 German emotion terms from three different groups: 9-year-old children and adults tested in a controlled laboratory setting, and adults tested via online survey. Results demonstrate high correlations for valence and arousal across settings. The comparison between children and adults also revealed high correlations, suggesting that children at the age of 9 already display adultlike behavior in their evaluation of emotion terms. A small difference was found for absolute rating values of arousal, with children rating words less arousing than adults. Overall, 9-year-olds and adults are sufficiently similar in their perception of emotion to warrant the use of adult valence and arousal ratings in the analysis of children data.
