Time-dependent discrimination advantages for harmonic sounds suggest efficient coding for memory	2020-10-15		.txt	text/plain	13309	653	48	The similarity in performance between harmonic and inharmonic tones without a delay provides circumstantial evidence that listeners are computing changes in the same way for both types of stimuli, presumably using a representation of the spectrum in both cases. We examined the relationship between pitch perception and memory by measuring the discrimination of harmonic and inharmonic sounds with and without a time delay between stimuli. The results provide evidence for two distinct mechanisms for pitch discrimination, reveal the constraints that determine when they are used, and demonstrate a form of abstraction within the auditory system whereby the representations of memory differ in format from those used for rapid on-line judgments about sounds. We found consistent overall pitch discrimination advantages for musicians compared to non-musicians ( Supplementary Figures 1-3 ), but found no evidence that this benefit was specific to f0 representations: musicianship did not interact with the effects of inharmonicity or inter-stimulus delay.	./cache/cord-103757-fed21fhu.txt	./txt/cord-103757-fed21fhu.txt
