Behavior task. (A) Subjects faced a screen with a target (blue) that moved vertically up and down, and controlled a cursor (yellow) using a joystick. The error difference (Δ) between the actual positions of the target and cursor was amplified by a scaling factor (α): Δ ×α = displayed visual error feedback. In the ‘Better’ (B) condition, α was set to 0.3, and in the ‘Worse’ (W) condition, α was set to 2, such that it appeared that subjects performed better or worse respectively based on their visual error feedback. (B) Trials (90 s) alternated between B and W conditions (each condition 30 s). Each trial was followed by a break of 30 s until a culmination of eight trials total were completed for the experiment.
