Experimental design. The experiment consisted of four conditions: long trial (LT) deviants-only, LT oddball, short trial (ST) deviants-only, and ST oddball paradigms. LTs consisted of two identical 20-min blocks, separated by a break, while STs consisted of single 15-min blocks. The figure shows the stimuli sequence: S = nontarget stimulus (1000 Hz), D (shaded) = target stimulus (1200 Hz). Target stimulus was presented at the same times in each condition. The subject was instructed to compress the hand dynamometer in response to target stimulus.
