AbstractViewing pictures of social interaction can facilitate approach behaviors. We conducted two studies to investigate if social interaction cues, empathy, and/or social touch modulate facial electromyographic (EMG) reactivity (as evidenced by the zygomaticus major and corrugator supercilii muscles) and mood states. We presented bonding pictures (depicting social interaction) and control pictures (without social interaction) while continuously recording zygomatic and corrugator EMG activities. In both studies, picture blocks were paired by valence and arousal. All participants were college students. In study 1, participants (n = 80, 47 women) read relevant priming texts immediately before viewing each block of 14 pictures. In study 2, participants did not read (n = 82, 63 women) priming texts before each block of 28 pictures. In study 1 and study 2, participants also completed mood states questionnaires to assess sociability and altruistic behavior. Empathy and social touch frequency were also assessed by self-reported questionnaires. In both studies, bonding pictures increased the zygomatic activity and the self-reported sociability feeling compared to control pictures. Only in study 2, bonding pictures decreased median corrugator activity compared to control pictures. We concluded that social interaction cues were efficient to increase sociability and prompt a sustained smile expression regardless of priming texts.

And Control

Visual contents such as movies and animation evoke various human emotions. We examine an argument that the emotion from the visual contents may vary according to the contrast control of the scenes contained in the contents. We sample three emotions including positive, neutral and negative to prove our argument. We also sample several scenes of these emotions from visual contents and control the contrast of the scenes. We manipulate the contrast of the scenes and measure the change of valence and arousal from human participants who watch the contents using a deep emotion recognition module based on electroencephalography (EEG) signals. As a result, we conclude that the enhancement of contrast induces the increase of valence, while the reduction of contrast induces the decrease. Meanwhile, the contrast control affects arousal on a very minute scale.

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.

A 9-week leisure education program to increase activity involvement and social interaction of institutionalized mentally retarded adults was investigated. A disproportional stratified (by residential unit) random sampling technique was employed to select 40 subjects from a total population of 243 mentally retarded persons. Subjects were randomly assigned to treatment and control groups. The hypotheses were that there would be no significant increase in activity involvement or social interaction of the subjects who participated in the treatment. Four ANCOVAs were conducted utilizing frequency and duration as the dependent variables for both social interaction and activity involvement. Length of institutionalization was the covariate. The grouping variables were treatment/control and level of retardation. The findings revealed the treatment had a significant effect only on frequency of activity involvement.

We employ cortical mesoscale calcium-imaging to observe brain activity in two head-fixed mice in a staged social touch-like interaction. Using a rail system, mice are brought together to a distance where macrovibrissae of each mouse make contact. Cortical signals were recorded from both mice simultaneously before, during, and after the social contact period. When the mice were together, we observed bouts of mutual whisking and cross-mouse correlated cortical activity in the vibrissae cortex. This correlated activity was specific to individual interactions as the correlations fell in trial-shuffled mouse pairs. Whisk-related global GCAMP6s signals were greater in cagemate pairs during the together period. The effects of social interaction extend outside of regions associated with mutual touch and had global synchronizing effects on cortical activity. We present an open-source platform to investigate the neurobiology of social interaction by including mechanical drawings, protocols, and software necessary for others to extend this work.

Abstract Pleasant touching is an important aspect of social interactions that is widely used as a caregiving technique. To address problems resulting from a lack of available human caregivers, previous research has attempted to develop robots that can perform this kind of pleasant touch. However, it remains unclear whether robots can provide such a pleasant touch in a manner similar to humans. To investigate this issue, we compared the effect of the speed of gentle strokes on the back between human and robot agents on the emotional responses of human participants (n = 28). A robot or a human stroked on the participants’ back at slow and medium speeds (i.e., 2.6 and 8.5 cm/s). Participants’ subjective (valence and arousal ratings) and physiological (facial electromyography (EMG) recorded from the corrugator supercilii and zygomatic major muscles, and skin conductance response) emotional reactions were measured. The subjective ratings demonstrated that the medium speed was more pleasant and arousing than the slow speed for both human and robot strokes. The corrugator supercilii EMG showed that the medium speed resulted in reduced activity in response to both human and robot strokes. These results demonstrate similar speed-dependent modulations of stroke on subjective and physiological positive emotional responses across human and robot agents and suggest that robots can provide a pleasant touch similar to that of humans.

In the current study I examined whether interpretive movement to music enhances emotional experience of the music, in dancers and non-dancers. Participants interacted with a series of musical excerpts, varying in valence and arousal, by either sitting still (still condition), moving arms up and down to the beat of the music (constrained condition), or gesturing their arms freely to the music (free condition), allowing for creative interpretation. Physiological and self-reported emotional responses to these songs were compared post-interaction. I found that after free gesturing, experienced dancers had polarized valence and arousal ratings towards happy vs. sad excerpts as opposed to after still and constrained conditions. Similar results were obtained of skin conductance (sweat) and zygomaticus major (smiling) responses. Non-dancers showed no difference in ratings or physiological responses between interaction conditions. This suggests that the effects of movement on emotional responsiveness to music are mediated by dance training.

The objective of the study was to find out whether the group guidance services could improve students' social interaction. This research uses a quantitative approach through experiment. In this study, the subjects from the study were 26 students divided into an experimental group of 13 students and control group of 13 students. Data collected by questionnaire. Data were analyzed using Wilcoxon signed-rank test. The results showed that social interaction ability of experiment class students can be improved after receiving group guidance service. As for the control class which was not given group guidance service, the result showed that the level of social interaction ability did not increase significantly. These results illustrate that social interaction can be enhanced through group guidance services.

AbstractTime perception relies on the motor system. Involves core brain regions of this system, including those associated with feelings generated from sensorimotor states. Perceptual timing is also distorted when movement occurs during timing tasks, possibly by interfering with sensorimotor afferent feedback. However, it is unknown if the perception of time is an active process associated with specific patterns of muscle activity. We explored this idea based on the phenomenon of electromyographic gradients, which consists of the dynamic increase of muscle activity during cognitive tasks that require sustained attention, a critical function in perceptual timing. We aimed to determine whether facial muscle dynamic activity indexes the subjective representation of time. We asked participants to judge stimuli durations (varying in familiarity) while we monitored the time course of the activity of the zygomaticus-major and corrugator-supercilii muscles, both associated with cognitive and affective feelings. The dynamic electromyographic activity in corrugator-supercilii over time reflected objective time and this relationship predicted subjective judgments of duration. Furthermore, the zygomaticus-major muscle signaled the bias that familiarity introduces in duration judgments. This suggests that subjective duration could be an embodiment process based in motor information changing over time and their associated feelings.
