Effects of Music and Storytelling on Linguistic, Socioemotional, and Adaptive Development in Children Aged 12-36 Months: an Intervention Protocol in Municipal Early Childhood Centers

This randomized clinical trial aims to evaluate the impact of a structured enriched environment on the linguistic, adaptive behavior, and socioemotional development of children aged 12 to 36 months. The study addresses two main questions: Does the intervention improve linguistic, adaptive behavior, and socioemotional development compared to standard care? Does parental guidance amplify the benefits of the intervention? Participants will be randomly assigned to one of two groups: Intervention Group: Children will participate in musical activities twice per week (singing, exploring simple instruments, and musical games) and daily storytelling sessions using interactive and visual aids. Within this group, parents in the "with guidance" subgroup will attend biweekly meetings to learn strategies for reinforcing the intervention at home, while the "without guidance" subgroup will not include parental training. Control Group: Children will receive standard care complemented by alternative artistic and pedagogical activities (e.g., drawing, painting), without the structured intervention.
