Joint attention is not the same for both individuals because one initiates it and the other responds. In a recent paper, researchers studied shared attention (Takahiko Koike etal; Neural substrates of shared attention as social memory: A hyperscanning functional magnetic resonance imaging study ; NeuroImage 125 (2016) 401–412). This cannot be done on an individual level as it involves social exchange and so the researchers used fMRI hyperscanning. Real time video recording and projection allowed two individuals in
