Set-up was identical at events, but either in a 3m x 3m gazebo or a quiet, screened off area of a community centre. Chairs were placed with the front edges of the seat 20 cm away from one another, so that actors sitting directly next to one another would be within arm’s distance (Peripersonal space) but those sitting further away would not (Extrapersonal space). Participants were seated 120 cm from the screen, in a semi-circle.
Fig 2.
Stimulus presentation sequence for a single trial.
Duration of screen presentation displayed below screen shots. The example shows a Compatible trial, where green is the correct response. For incompatible trials, the finger does not point towards the correct response, but rather to one of the other colours. Peripersonal trials are where the finger points towards the response option directly next to the correct response (yellow or pink in this example), compared to Extrapersonal trials where it points towards a more distant response option (e.g., blue or red).

Fig 6.
Mean response time during peripersonal trials, split into number of peripersonal positions available (1 or 2) and by familiarity to the dyad (familiar, stranger, empty seat or self (i.e., compatible trials).
Error bars represent standard errors.
Fig 7.
Mean response time during peripersonal trials with two peripersonal spaces, split into number of peripersonal familiar individuals present (0, 1 or 2).
Data are split between incompatible and compatible trials. Error bars represent standard errors.
Fig 8.
Mean response time during peripersonal trials with two adjacent spaces, split into the relationship with the incompatible target seat (empty, stranger, familiar) by the relationship with the other adjacent seat.
Error bars represent standard errors.
