approached significancep = 0.03
Planned contrasts comparing TIW within expertise groups, between stimulus instrument categories, showed that pianists had a narrower TIW for piano stimuli than for clarinet stimuli, which approached significance at a Bonferroni-adjusted alpha of 0.02, z = 2.5, p = 0.03, and a significantly narrower TIW for piano stimuli than for violin stimuli, z = 2.8, p = 0.01.
