Acquisition performance was assessed using a 3-factor (group [participants with stroke, control participants] × information (EI, No-EI) × day [1, 2, 3]) analysis of variance (ANOVA), with repeated-measures correction for day and RT change score as the dependent measure. Subsequently, post hoc tests were performed to identify the locus of interactions. These tests separately examined information of the sequence (information × day ANOVA) and between-group differences (group × day ANOVA).
