The behavior of two real-time computer simulation models of melody recognition was compared with the performance of human subjects in this study. One of the models, INT1, recognized melodies by comparing specific intervals with stored intervals. The other model, CONT1, performed by comparing the contour of the stimulus melody with an array of melody intervals. The 20 intermediate and advanced psychology majors who volunteered to participate in the study were tested on the speed and accuracy of their recognition of 20 familiar melodies. In regression analyses, these data were regressed against the two computer models, and the results indicated that the contour analysis simulation (CONT1) was a more adequate predictor of human recognition than was the interval analyzer program. Four references are listed, and several graphs depicting the results are appended. (MES)
