(A) Average eyeblink frequency for each block. (B) Average eyeblink duration for each block. (C) Average saccades frequency for each block. (D) Average saccades amplitude for each block. All figures’ y-axes show their value respectively, and x-axes show blocks, where odd blocks represented by square markers are the low motivation blocks. Error bars in each block represent standard errors.
