Implicit learning of SEQA in controls. A: mean spatial errors (±SE) per cycle of control groups 1 and 3 are plotted for RAN (filled gray squares), CCW (empty gray squares), SEQAtrain (filled black circles), and SEQAtest (empty black circles). Empty diamonds and dotted lines represent the mean MT for correct anticipatory movements in SEQAtrain. Data for the 2 control groups were combined because no difference was found between them. Spatial errors decreased over the course of SEQAtrain and further improvement occurred on day 2. B: mean MTs (±SE) per cycle of the 2 control groups combined are plotted for RAN, CCW, SEQAtrain, and SEQAtest and correct anticipatory movements in SEQAtrain. Symbols are the same as in A.
