Table 6. Reaction times (mean ± standard deviation, measurement unit: ms) corresponding to congruent (CT), low conflict (LT) and high conflict trials (HT) as well as reaction time differences (mean ± standard deviation, measurement unit: ms) among trials obtained within each task (PI =  prosody identification, SI =  semantics identification, VI =  vowel identification).
