EEG hyperscanning and behavioral synchronization during a joint actions

Abstract

Brain-to-brain coupling during cooperation is a core question of study on social interactions. The aim of the present study was to investigate the neural basis of interbrain cooperation and the cognitive performance underlying the execution of jointactions by using EEG coherence measures. Synchronicity of the cognitive variables (response times, RTs, and error rates, ERs) in response to an attentional task, intersubjective coherence analysis on EEG frequency bands, and correlational measures between cognitive and brain activity were considered during some steps of progressive reinforcing conditions. Fifteen couples of subjects performed an attentional task in eight temporal steps, stressing their good performance at the end of each step. The induced feedback affected both the cognitive performance and brain-to-brain coupling by increasing behavioral and brain synchronization when a positive feedback was furnished to the participants for their performance. Secondly, about the cortical contribution, high coherence effect was mainly observed when a positive reinforce was produced, but only for some low frequency bands within the prefrontal left area, compared to the right one. Thus, also a left lateralization effect was reportable. Finally, the cognitive and EEG coherence measures were shown to be correlated, with a significant similar trend anchored to the progressive feedback.

“…A growing body of studies using a new brain imaging technique-hyperscanning, 26 which allows measurement of the activity of multiple brains simultaneously-has revealed that neuronal oscillations are also influenced by social dynamics. 27,28 In particular, natural social interactions produce a brain-to-brain synchrony in neural oscillations during natural social interactions that is linked with behavioral synchrony. In other words, synchronized neuronal oscillations coordinate people physically by regulating how and when their bodies move together.…”

Brain-to-Brain Neural Synchrony During Social Interactions: A Systematic Review on Hyperscanning Studies

“…The motor synchronization application makes up 23% (14/60) of the research done with the MEG/EEG neuro-imaging methodology [41,58,[102][103][104][105][106][107][108][109][110][111][112][113]. The goal of these studies was to look at how participants are able to coordinate their actions with each other.…”

“…The goal of these studies was to look at how participants are able to coordinate their actions with each other. This was most commonly done by asking participants to perform a motor task such as rhythmically tapping their fingers [41,104,105], following someone's lead (imitation) to tap the sensors at the same time [102,106,[108][109][110], or other motor/selective attention tasks [68,107,[111][112][113]. Motor synchronization studies were also done via a computer by asking participants to try to coordinate their response times to different matching/shapes games.…”

L’hyperscanning: o come comunicano i cervelli nelle organizzazioni?

“…Infatti, l'applicazione dell'hyperscanning si è recentemente evoluta passando dall'osservazione dei meccanismi di sintonizzazione neurale e corporea durante lo svolgimento di compiti interattivi (Montague et al, 2002) o economici (King-Casas et al, 2005) a contesti d'interazione reali, come: esibizioni musicali (Lindenberger, Li, Gruber, & Müller, 2009); situazioni cooperative o competitive, che richiedono la sincronizzazione o desincronizzazione delle risposte degli individui durante l'esecuzione di un compito attentivo (Balconi & Vanutelli, 2018); scambi comunicativi che implicano l'osservazione e la riproduzione di differenti categorie di gesti e contesti prosociali, in cui agli individui viene richiesto di svolgere un compito congiunto prima e dopo lo scambio di un dono (Balconi & Vanutelli, 2017a;Balconi et al, 2019;Balconi et al, 2020a).…”
