Mean number of words defined correctly in the Dose 4 × Dose Frequency 9 treatment (circles), the Dose 6 × Dose Frequency 6 treatment (squares), and the Dose 9 × Dose Frequency 4 treatment (triangles) prior to treatment (i.e., baseline), during treatment, and posttreatment. Data are collapsed across Treatment 1 and Treatment 2 and usually involve collapsing Set 1 and Set 2 words with two exceptions: (a) Untreated words are Set 2 words tested at baseline, immediately post–Treatment 1, and 2 weeks post–Treatment 1, and (b) longitudinal data are Set 1 words tested immediately post–Treatment 2 and 2 weeks post–Treatment 2. Error bars indicate standard errors.
