Music perception (Peretz & Kolinsky, 1993) The authors analyzed the performance of a clinical case, C.N., and a control group using a task in which they had to compare musical fragments. In some of the comparisons, discrimination involved a Stroop-type test situation. Four type of comparisons were used. Music fragments to be compared could differ on the basis of melody or rhythm alone, or they could be similar or different in both dimensions: - DS comparison: fragments differed only in the melody, with change in the third note but with the same duration of all the elements. - SD comparison: the melody was the same but the duration of the second and third elements differed. - SS comparison: similar fragments in both dimensions - DD comparison: fragments differed in both dimensions. In comparisons involving DS or SD fragments (incongruent ones), it was necessary to selectively attend to one dimension and ignore the other one. Results indicate that only the C.N. patient studied could adequately ignore the interference in the incongruent comparisons, precisely because of his selective disorder affecting melodic perception (right hemisphere lesion). The control group participants showed lower performance in these incongruent comparisons because they had difficulties ignoring interference caused by the not-to-be-attended dimension, as in the classic Stroop effect. Question: Why do you think C.N percentage of correct answers in the congruent condition is rather similar to the results from the control group?
