Table 3: Statistical Effects of Diagnosis, Age, RT, and Sensory Cue on MRCP amplitude. Results of a general linear mixed model evaluating the effect of task parameters (sensory condition: A, V, AV), participant characteristics (age, group) and performance measures (RT within each of four bins: fastest 25% of trials, middle 25-50% of trials, middle 50-75% of trials, slowest 25% of trials) on individual participant amplitude within each of three time windows. (A) Late BP (-350 to 0 ms), (B) Motor Potential [MP] (0 to 25 ms), (C) Reafferent potential [RAP] (90 to 130 ms).
