“…In addition, we predicted heightened ERP responses, manifested as increased positivity over parietal electrodes in response to targets (P3b) and to emotional IAPS stimuli (LPP). Lastly, in line with previous studies we expected to find stronger alpha suppression in the shared condition, indicating increased attentional processing 45 as well as stronger mu suppression, indicating more social involvement, as was previously found in response to social context 37,38 .

“…When executing or observing actions, sensorimotor mu rhythms show a desynchronization of activity, as reflected in suppressed power relative to pre-action levels [34][35][36] . Moreover, greater mu suppression is found in social compared to non-social contexts, such as when one is participating in a social interaction 37,38 , deciphering the intentions of others from biological motion 39,40 , and understanding facial expressions 41 , or levels of pain 36 of others. Note that apart from mu suppression, alpha suppression, measured in the same frequency range, but over parietal-occipital areas has been repeatedly shown to be affected by visual attention 31,36,[42][43][44] .…”

Shared attention experiments examine the potential differences in function or behavior when stimuli are experienced alone or in the presence of others, and when simultaneous attention of the participants to the same stimulus or set is involved. Previous work has found enhanced reactions to emotional stimuli in social situations, yet these changes might represent enhanced communicative or motivational purposes. This study examines whether viewing emotional stimuli in the presence of another person influences attention to or memory for the stimulus. Participants passively viewed emotionally-valenced stimuli while completing another task (counting flowers). Each participant performed this task both alone and in a shared attention condition (simultaneously with another person in the same room) while EEG signals were measured. Recognition of the emotional pictures was later measured. A significant shared attention behavioral effect was found in the attention task but not in the recognition task. Compared to event-related potential responses for neutral pictures, we found higher P3b response for task relevant stimuli (flowers), and higher Late Positive Potential (LPP) responses for emotional stimuli. However, no main effect was found for shared attention between presence conditions. To conclude, shared attention may therefore have a more limited effect on cognitive processes than previously suggested. Humans are social animals that often prefer acting together, rather than alone 1,2. Potential differences in function or behavior when experienced alone or in the presence of others are referred to as co-presence effects that can be either generated from the mere presence of another or from a shared experience that occurs in the physical or psychological presence of another person 3-5. When simultaneous attention of the participants to the same stimulus or set is involved, shared experience overlaps with the term shared attention 4,6. Indeed, both shared experience and shared attention have been found to affect cognitive function and behavior, such as attention to a target stimuli 3,7 , social learning 8 , memory 9,10 , motivation 11 , judgment 12 and inhibitory control 13. Specifically, shared attention has been found to amplify these processes (etc. memories, emotions, and behavioral learning) 4,6. For example, higher manifestation of social learning was found in the shared attention condition compared to an unshared condition 8. Several 5,14,15 studies have examined the effect of shared attention in emotional contexts, but yielded mixed results. For example, Shteynberg and colleagues examined online shared attention effects on reactions to emotional stimuli. In a series of studies, they presented either short clips or pictures to participants and found enhancement of the subjective feelings (self-reported) for emotional stimuli in the online presence of another person. Specifically, scary advertisements led to higher "scariness" scores in the shared attention condition compared to the same stimuli viewed alone. Similar...

“…Also consistent with our predictions, specification of the individual actions as well as of the joint configuration by the pre-cue resulted in enhancement of the alpha/mu rhythm and of the late CNV amplitude. Suppression of the sensorimotor alpha/mu rhythm prior to an action is related to planning processes (Behmer and Fournier, 2014; Kourtis et al, 2013a, 2013b) and it may also reflect processing of interpersonal coordination (Yin et al, 2017). Importantly, the alpha/mu suppression in the present study was lateralized over primary sensorimotor areas contralateral to the acting hand, which strongly suggests that it reflected action preparation and not simply anticipation of the centrally-presented Go cue (Pfurtscheller et al, 1997).…”

Do people engaged in joint action form action plans that specify joint outcomes at the group level? EEG was recorded from pairs of participants who performed coordinated actions that could result in different postural configurations. To isolate individual and joint action planning processes, a pre-cue specified in advance the individual actions and/or the joint configuration. Participants had 1200 ms to prepare their actions. Then a Go cue specified all action parameters and participants performed a synchronized action as quickly as possible. Action onsets were shorter when the pre-cue specified the joint configuration, regardless of whether individual action was also specified. EEG analyses showed that specifying joint action parameters in advance reduced ambiguity in a structured joint action plan (reflected in the decrease of the amplitude of the P600) and helped with representing action goals and interpersonal coordination patterns in sensorimotor brain areas (reflected in increased alpha/mu suppression and CNV amplitudes). These results provide clear evidence that joint action is driven not only by action plans that specify individual contributions, but also by action plans that specify joint action outcomes at the group level.

“…Compte tenu en outre du développement important de la littérature relative aux neurones miroirs, une compréhension précise des propriétés et des fonctions présumées de ces neurones paraît primordiale pour éviter les simplifications abusives. Par ailleurs, le développement de nouvelles approches expérimentales tant chez l'animal que chez l'homme, devrait permettre de renforcer les différents modèles relatifs aux phénomènes complexes qui impliquent les neurones miroirs, telle que l'imitation [106,107], l'empathie [108], la coordination sociale [109][110][111] ou encore l'autisme [112].…”
