“…The study showed that an individual’s typical use of bright (“laughing-with”) and dark (“laughing-at”) humour is linked to the brain’s automatic responses to incoming social-emotional information. Greater typical use of benevolent humour, the goals and intentions of which are in keeping with the characteristics of “laughing-with” humour, was associated with greater relative decreases of prefrontal-posterior coupling during the processing of other people’s happy laughter, allowing the brain to become more affected by this apparently rewarding social-emotional signal 24 25 26 27 28 29 . Greater typical use of the three humour styles that were consistent with malicious intentions of “laughing-at” humour (cynicism, sarcasm, irony 17 ) was associated with greater relative decreases of prefrontal-posterior coupling (i.e., a wider opened perceptual gate) during the processing of other people’s crying.…”

“…The clips were matched for peak sound intensity and sound level range, and were presented over headphones. They have been used in several previous studies 25 26 27 28 29 . The displayed emotions are unambiguous and intense; healthy participants have no difficulties identifying and differentiating the expressed affective states 25 29 .…”

“…More loose prefrontal-posterior coupling during social-emotional processing, especially in the right hemisphere, indicates loosening of control of the prefrontal cortex over the incoming perceptual information, thereby opening up the perceptual gate and allowing the brain to become more affected by the social-emotional signals. By contrast, functional coupling increases during exposure to aversive information, protecting the individual from being unduly affected by the aversive input 24 25 26 27 28 29 .…”

The ways in which humour can be used are related to the manifold interpersonal functions humour can serve, some of which are positive, and some negative. In the present study, phasic changes in the functional coupling of prefrontal and posterior cortex (EEG coherence) during other people’s auditory displays of happy and sad mood were recorded to predict people’s typical use of humour in social interactions. Greater use of benevolent humour, the intentions of which are in keeping with the characteristics of “laughing-with” humour, was associated with greater decreases of prefrontal-posterior coupling during the processing of happy laughter. More loose prefrontal-posterior coupling indicates loosening of control of the prefrontal cortex over the incoming perceptual information, thereby opening up the perceptual gate and allowing the brain to become more affected by the social-emotional signals. Greater use of humour styles linked to malicious intentions of “laughing-at” humour was associated with responses indicating a wider opened perceptual gate during the processing of other people’s crying. The findings are consistent with the idea that typical humour styles develop in line with the rewarding values of their outcomes (e.g., interaction partners are happy or hurt), which in turn are defined through the individuals’ latent interpersonal goals.

“…In our experimental paradigm, we consider the interaction of changes in emotional stimuli and neural responses thereto as potential correlates of self-regulation. Decreases in beta frequency band prefrontal-posterior EEG coherence induced by emotional stimulation reflect a loosening of the prefrontal cortex's regulatory control of parietal regions 9,[11][12][13][14][15] . Therefore, beta coherence plays a critical role in brain networks responding to emotion-cognition interaction.…”

Although emotions often result from dynamic experiences with self-regulation unfolding over time, most research has focused on responses to affective stimuli from a rather static perspective. We studied and analyzed emotion transitions, attempting to reveal brain functions related to affect dynamics. EEG responses were examined during exposure to stable versus changing emotion-eliciting images (static vs dynamic conditions) plus their impact on executive function (EF) assessed with the flanker task. During dynamic conditions, reduced prefrontal to posterior EEG coherence in the beta frequency band and greater left frontal activity occurred compared to the static conditions. Among individuals suffering higher chronic stress, subsequent EF was hindered after dynamic conditions. Furthermore, the adverse effects of emotion transitions on EF for more chronically stressed individuals were mediated by prefrontal-posterior coherence in low beta frequency band during emotional image sequences. Emotion appears to influence EF through changes in large-scale synchronization. Individuals high in chronic stress are vulnerable to these effects.

“…Lastly, in an electroencephalogram (EEG) study, individuals with schizotypy showed impaired processing for social-emotional information. These individuals showed less prefrontal-posterior functional coupling than controls, which is considered to be indicative of a mechanism to protect the individual from becoming overwhelmed by the perception of social-emotion information, during exposure to auditory displays of strong emotion (Papousek et al, 2014 ).…”

Schizotypy refers to the personality trait of experiencing “psychotic” symptoms and can be regarded as a predisposition of schizophrenia-spectrum psychopathology (Raine, 1991). Cumulative evidence has revealed that individuals with schizotypy, as well as schizophrenia patients, have emotional processing deficits. In the present study, we investigated multimodal emotion perception in schizotypy and implemented the machine learning technique to find out whether a schizotypy group (ST) is distinguishable from a control group (NC), using electroencephalogram (EEG) signals. Forty-five subjects (30 ST and 15 NC) were divided into two groups based on their scores on a Schizotypal Personality Questionnaire. All participants performed an audiovisual emotion perception test while EEG was recorded. After the preprocessing stage, the discriminatory features were extracted using a mean subsampling technique. For an accurate estimation of covariance matrices, the shrinkage linear discriminant algorithm was used. The classification attained over 98% accuracy and zero rate of false-positive results. This method may have important clinical implications in discriminating those among the general population who have a subtle risk for schizotypy, requiring intervention in advance.
