Differential skills of perception of frequency.

This study aimed to develop tests for differentiating auditory perception skills, e.g., to test drug effects. In Exp. 1 (N = 60), discrimination of succeeding frequencies, frequency identification assessed by a choice reaction task, and the perception of pitch contour assessed by frequency deviants in binaural melodies showed zero partial correlations. In Exp. 2 (N = 36), discrimination correlated with performance on a field dependence test; fast frequency identification correlated with verbal fluency. The auditory tests are likely suitable for assessing distinct skills, but correlations with general cognitive abilities require further investigations.
