Paradigm of the audio-tactile interaction task used in the behavioral experiments. Participants responded to a tactile stimulus on their hand, while task-irrelevant sounds either approached toward (IN sounds) or receded from (OUT sounds) their hand. On each trial, the tactile stimulus was delivered at one out of five possible different delays from sound onset, so that it was processed when the sound was perceived at a different distance from the subject's body (from D1, very far, to D5, very close).
