Sound perception: Index δ = (SP - H)/(SP+H) according to the number of perceived holistic (H) and spectral (SP) items of the sound perception test [1]. Age (years), musical expertise (hours of training per day) and sound perception index (δ) are presented as mean ± standard error (s.e.m.). ANOVA: p-value of WS vs. control group of spectral listeners (CSP) and WS vs. control group of holistic listeners (CH).
