Enhancing team coordination through interpersonal neural synchrony achieved with neurofeedback training

Recent studies have indicated that interpersonal neural synchrony (INS) in dyads may be increased through neurofeedback training (NFT), and that there might be a correlation between INS and interpersonal coordination. The current study aims to investigate these recent findings further by examining whether three sessions of INS-NFT can increase the INS and interpersonal coordination between two team members. Two research questions are investigated, namely: RQ1. Is frontal theta and delta INS-CCorr higher during a third session of INS-NFT than during the first session?, and RQ2. Is team coordination higher after three sessions of theta and delta frequency INS-NFT?. To explore these research questions, four teams of two participants have trained INS-NFT for three sessions of twenty-four minutes, receiving either actual or random feedback. Before and after INS-NFT, all teams completed a cooperative interpersonal coordination task during which interpersonal coordination was measured. The two research questions have been investigated through nine statistical analyses, which did not show a clear trend towards INS or interpersonal coordination being trainable through INS-NFT. Future research should examine these findings further.
