From: Neural hypersensitivity to pleasant touch in women remitted from anorexia nervosa
The soft touch continuous performance task. Participants were presented with either a left- or rightward pointing arrow on a gray background for 3 s and were asked to press the left or right button of a button box, using the index and middle finger of the right hand, which corresponded with the direction of the arrow. The arrow's background color indicated one of three conditions: 1) baseline, in which no stimulus was expected or administered (three consecutive arrow trials, or ~9 s duration); 2) anticipation of soft touch of the left forearm (yellow background, 6 s), for which the participant could expect a subsequent soft brushing of the forearm; and 3) anticipation of soft touch of the left palm (blue background, 6 s), which indicated the participant should expect a soft brushing of the palm. Following the anticipatory periods, the participant would experience a soft brush on either for forearm or palm (2 s)
