Table 8. Accuracy rates (mean ± standard deviation) corresponding to congruent (CT), low conflict (LT) and high conflict trials (HT), as well as accuracy rate differences (mean±standard deviation) between the different trial types obtained within each task (PI =  prosody identification, SI =  semantics identification, VI =  vowel identification) and experimental group.

Note: Slight discrepancies between (CT-HT)/(CT-LT)/(LT-HT) subtraction values and mean difference values reported in this table are due to rounding. Similarly discrepancies between overall means and corresponding averages of values reported for the patient group and healthy control group are introduced by rounding effects.
