This thesis aimed to analyze the findings of behavioral and electrophysiological auditory assessments of Central Auditory Processing (CAP) in children and adolescents undergoing musical auditory training, and to verify the effect of a structured Musical Auditory Training (MAT) protocol in children diagnosed with Central Auditory Processing Disorder (CAPD). The first article consisted of a systematic literature review, conducted according to PRISMA guidelines and registered in the Open Science Framework (OSF). Studies investigating the effects of musical auditory training in children and adolescents through behavioral and electrophysiological assessments were included. The findings demonstrated that musical auditory training promotes neural plasticity, as evidenced by improvements in auditory skills such as temporal discrimination and listening in noisy environments, in addition to inducing changes in auditory evoked potentials. These results reinforce its clinical applicability in CAPD rehabilitation. The second article was developed as a randomized clinical trial (RCT). Children diagnosed with CAPD were randomly allocated into experimental and control groups, receiving either the MAT protocol or a placebo intervention, with both participants and evaluators blinded to group allocation. Pre- and post-intervention analyses included CAP behavioral tests, parental perception questionnaires, and Long-Latency Auditory Evoked Potentials. Results revealed significant improvements in auditory skills and favorable electrophysiological changes only in the group that underwent MAT, confirming its effectiveness as an evidence-based therapeutic strategy. Taken together, the two studies—a systematic review and a randomized clinical trial—represent the highest levels of scientific evidence available. Thus, this thesis contributes to consolidating MAT as a promising and scientifically validated intervention for children with CAPD, providing relevant support for clinical practice in Speech-Language Pathology and for the development of public policies in child health and educativo.
