Physiological synchrony (PS) refers to the degree to which physiological measures of multiple individuals uniformly change (Palumbo et al., 2017). In a controlled laboratory study, we found that physiological synchrony reflects selective attention: The electroencephalogram (EEG), heart rate and electrodermal activity (EDA) of participants showed...

Interpersonal EEG synchrony derived from the hyperscanning technique has the potential to reveal brain mechanisms beyond the border of traditional analysis within an individual subject. However, the inter-brain connectivity has not been fully investigated using wearable consumer-grade EEG devices which can enable a variety of application in a...

Measuring concurrent changes in autonomic physiological responses aggregated across individuals (Physiological Synchrony - PS) can provide insight into group-level cognitive or emotional processes. Utilizing cheap and easy-to-use wearable sensors to measure physiology rather than their high-end laboratory counterparts is desirable. Since it is...

Physiological measures such as brain potentials as measured through electroencephalography (EEG), skin conductance or electrodermal activity (EDA) and heart rate can be informative of individuals’ attentional engagement. We are interested in exploiting such measures in real life situations. A challenge of interpreting physiological signals as...

We are interested in monitoring physiology out of the lab because of its potential informative value about mental state, such as stress. For real life studies or applications utilizing physiology, we need to equip individuals with wearables that are designed to be compatible with individuals performing their daily activities, which can come at...

Measuring psychophysiological signals of adolescents using unobtrusive wearable sensors may contribute to understanding the development of emotional disorders. This study investigated the feasibility of measuring high quality physiological data and examined the validity of signal processing in a school setting. Among 86 adolescents, a total of...

Interpersonal physiological synchrony (PS), or the similarity of physiological signals between individuals over time, may be used to detect attentionally engaging moments in time. We here investigated whether PS in the electroencephalogram (EEG), electrodermal activity (EDA), heart rate and a multimodal metric signals the occurrence of...

OBJECTIVE: Concurrent changes in physiological signals across multiple listeners (physiological synchrony-PS), as caused by shared affective or cognitive processes, may be a suitable marker of selective attentional focus. We aimed to identify the selective attention of participants based on PS with individuals sharing attention with respect to...

Physiological synchrony (PS) refers to the similar-ity in physiological responses of two or more individuals and may be an informative source of information in the field of affec-tive computing. Up to now, PS has been assessed using either autonomic measures or neural measures. While in literature multiple physiological channels have already...

Skin conductance or electrodermal activity (EDA) has been shown to be a reliable indicator of emotional arousal. With the current development to record EDA with wearable sensors attached to individuals who freely move around, detecting EDA artefacts is essential. Current practice of detecting EDA artefacts relies heavily on expert judgments....

Monitoring directed auditory attention in groups can be helpful in a range of contexts. Concurrent change in physiological variables across multiple listeners (physiological synchrony – PS) may be a suitable marker of attentional focus as caused by shared affective or cognitive processes. We here determine PS for EEG (electroencephalography),...
