Control Participants

Dawn Senathi-Raja

Given the lack of objective evidence of MR's premorbid perceptual musical abilities, the use of a control group was considered necessary. MR's performance on a range of auditory processing tasks was compared to a group of five male control participants matched for age, handedness, education, and musical background, as shown in Table 2.1. Each control was individually tested under conditions similar to MR including assessment in a quiet area of the home environment using identical task instructions and administration.
