از رفتار اجتماعی به هماهنگی مغز: نقد و بررسی و دیدگاه در اسکن کردن بیش از حد

Recently, the neuroscience field took a particular interest in the use of a neuroimaging technique called ‘hyperscanning’. This new technique consists in the simultaneous recording of the hemodynamic or neuroelectric activities of multiple subjects. Behind this small technical step lays a giant methodological leap. Groundbreaking insight in the understanding of social cognition shall be achieved if the right paradigms are implemented. A growing number of studies demonstrate the potential of this recent technique. In this paper, we will focus on current issues and future perspectives of brain studies using hyperscanning. We will also add to this review two studies initiated by Line Garnero. These studies will illustrate the promising possibilities offered by hyperscanning through two different key phenomena pertaining to social interaction: gesture imitation and joint attention.

More and more studies try to take a real look into ecological experimental settings. Some authors plead for cognitive ethology, meaning an observation of what happens in real life or at least creating situations that simulate the real world [41]. Scientific researches desperately need to get more and more real. Bringing the daily life into the lab is clearly a challenge for the next years [34] and more especially in the field of social neuroscience. In continuity with what was started under the direction of Line Garnero, our studies pursue this goal. These studies are compromises between the rigorous constraints of the scientific methods and the ecological needs of realistic tasks. We believe that they make a step further in the investigation of behaviour and brain synchronization during social interaction.
