Change in response time (RT) for the repeated sequence across acquisition on the serial reaction time (SRT) task for control participants and participants with stroke in the explicit information (EI) and No-EI groups. Error bars are the standard error of the mean. The zero line represents random-sequence RT. Data below this line illustrate faster RT and reflect implicit motor-sequence learning. Solid lines reflect data for participants in the EI group; dashed lines reflect data for participants in the No-EI group. (A) Acquisition performance data across 3 days of practice for the control participants. (B) Acquisition performance data across 3 days of practice for the participants with stroke.
