Musical practice and cognitive aging: two cross-sectional studies point to phonemic fluency as a potential candidate for a use- 2 dependent adaptation Brief running title: Musical practice and cognitive aging: Musical practice and cognitive aging

Abstract : Because of permanent use-dependent brain plasticity, all lifelong individuals' 26 experiences are believed to influence the cognitive aging quality. In older individuals, both 27 former and current musical practices have been associated with better verbal skills, visual 28 memory, processing speed, and planning function. This work sought for an interaction 29 between musical practice and cognitive aging by comparing musician and nonmusician 30 individuals for two lifetimeperiods (middle and late adulthood). Long-term memory, auditory-31 verbal short-term memory, processing speed, nonverbal reasoning, and verbal fluencies were 32 assessed. In Study 1, measures of processing speed and auditory-verbal short-term 33 memoryweresignificantly better performedby musicians compared with controls, but both 34 groups displayed the same age-related differences. For verbal fluencies, musiciansscored 35 higherthan controls and displayeddifferent age effects.In Study2, wefoundthat lifetime period 36 at training onset (childhood vs.adulthood) was associated with phonemic, but not semantic, 37 fluencyperformances (musicians who had started to practice in adulthood did not perform 38 better on phonemic fluency than nonmusicians). Current frequency of training did not account 39 for musicians' scores on either of these two measures. These patterns of results are discussed 40 by settingthe hypothesis of a transformative effect of musical practiceagainst a noncausal 41 explanation.
