Table 3.
Summary of training study data for each individual and group averages. Accuracy and RT are computed per letter. Observations for Accuracy Analysis = number of letters attempted over the course of the study. Observations for RT Analysis = number of words spelled correctly over the course of the study. S = seconds. First or last 25% indicates the mean during the initial or final quarter of the training program and follow-up accuracy refers to accuracy approximately 3 months after the end of treatment.
