Auditory concept identification as a function of subject sex and stimulus dimensions

Binary stimulus dimensions of duration, laterality, frequency, amplitude, and number were compared for their respective information values in auditory concept identification of males and females. Amplitude, without irrelevant information, was shown to provide significantly less information than the other dimensions with the exception of number. Males performed significantly poorer than females with laterality relevant under conditions of 1, 2, and 3 irrelevant dimensions. Sex differences in laterality were replicated with additional Ss.
