| Objective:To investigate whether the influence of music experience on the fluid intelligence of middle-aged and elderly ethnic minorities is mainly reflected in processing speed or executive function.Methods : The processing speed tests(including special symbol search,digital symbol search,simple response time and selective response time tasks)and executive function tests(including N-back,flanker,GO/NO-go and local-global tasks)were used to measure the middle-aged and elderly ethnic minorities with or without music experience.The two groups were matched by age,education level and the GDS scores.Results:Subjects with music experience were faster in special symbol search and digital symbol search tasks than those without music experience.However,two groups performed similarly in simple response time and selective response time tasks.Subjects with music experience showed higher accuracy than those without music experience in 2-back tasks.Subjects with music experience showed lower effects of conflict adaptation than those without music experience.Subjects with music experience showed higher accuracy and less conversion cost in accuracy than those without music experience in local-global tasks.However,two Groups showed no significant difference in GO/NO-go tasks.Conclusion:Music experience gradually accumulated in daily life had a positive impact on the general cognitive ability and specific cognitive ability of the middle-aged and elderly ethnic minorities,and this positive impact was more obvious on the more difficult cognitive tasks. |
