摘      要：Objective:To test for pre-attentive auditory discrimination skills in Indian classical vocal musicians and ***:Mismatch negativity(MMN) was recorded to test for pre-attentive auditory discrimination skills with a pair of stimuli of /1000 Hz/ and/1100 Hz/,with /1000 Hz/ as the frequent stimulus and /1100 Hz/ as the infrequent ***,offset and peak latencies were the considered latency parameters,whereas peak amplitude and area under the curve were considered for amplitude *** sample:Exactly 50 participants,out of which the experimental group had 25 adult Indian classical vocal musicians and 25 age-matched non-musicians served as the control group,were included in the *** group participants had a minimum professional music experience in Indian classic vocal music of 10 ***,control group participants did not have any formal training in ***:Descriptive statistics showed better waveform morphology in the experimental group as compared to the *** showed significantly better onset latency,peak amplitude and area under the curve in the experimental group but no significant difference in the offset and peak latencies between the two ***:The present study probably points towards the enhancement of pre-attentive auditory discrimination skills in Indian classical vocal musicians compared to *** indicates that Indian classical musical training enhances pre-attentive auditory discrimination skills in musicians,leading to higher peak amplitude and a greater area under the curve compared to non-musicians.
