 **Task (permanence memory).** A ball is hidden under one of three cups and the cups are swapped; the robot picks up the chips can and places it on the pad of that cup's final slot. The cue (cups swapped (about 3.6 s)) has ended before the robot acts on it, and the instruction does not name the answer.
