Experimental protocols. A| The detection threshold experiment: the detection threshold was measured before and after a 2 minute conditioning stimulus. In each trial sequence, two 1-s stimulus intervals were presented with a 1-s intervening period. Only one interval contained a stimulus and the location of the stimulus in interval 1 or 2 was randomized. The response interval was 4 s long and contained a 3-s “boost” of the conditioning stimulus in the adapted threshold trials, but not in the unadapted threshold trials. B| The intensity tracking experiment: the intensity of a constant stimulus was rated every ten seconds for 3 minutes.
