Fig 1. Trial sequence.
Each trial started with a fixation cross (400 ms.) and a brief blank screen. Each action started with an image showing one of the two individuals (John, left; Claire, right) in one of the two situations (at a computer, top; near a soccer ball, bottom). They then either interacted with the object or turned away from it, with one individual typically interacting with one object and turning away from the other, and vice versa for the other individual.
