The grating stimuli and experimental setup used in experiments 1 and 2. Grating stimulus pairs consisting of two square wave gratings mounted either side of a single card as shown in (a). Participants attended to the target grating, touched by their right thumb while the experimenter held the card in place (b). Distractor gratings were touched simultaneously by the right index finger (in one-handed conditions) or left index finger (two-handed conditions). Hand postures are shown in (c).
