Relationship between years of practice with perceptual and cognitive measures (musicians only).

Correlations between years of musical experience and the cognitive and perceptual measures for the musician group only. No significant relationships were found between years of musical experience and these cognitive and perceptual measures. However, perceptual and cognitive skills do not improve monotonically over the lifespan, rather they are negatively affected by age. The absence of a significant relationship is not surprising given the linear nature of years of musical experience and these nonlinear perceptual and cognitive measures.
