The impact of a music enrichment program during infancy and early toddlerhood on effortful control at age 3: A preliminary investigation

Abstract

Effortful control (EC), a self‐regulation skill, is associated with long‐term developmental outcomes. Music has been associated with infant self‐regulation and may be an intervention strategy for enhancing EC during toddlerhood. This investigation included 32 parent‐child dyads from a previously conducted randomized controlled trial (RCT). Participants (9‐15‐months old at baseline) attended either a music enrichment program or a playdate control once a week for 1 year and monthly for an additional year. At age 3, participants completed snack and gift delay effortful control tasks. Groups were compared using one‐way ANOVA. We found that participants in the music group had a significantly higher score during snack delay (music mean = 3.47 ± 0.94; control mean = 2.45 ± 1.51; p = 0.03; Cohen's d = 0.84). We did not find a significant group difference for latency to peek (music mean = 39.10 ± 20.10; control mean = 30.90 ± 19.88; p = 0.25; d = 0.57) or latency to touch (music mean = 105.73 ± 417.69; control mean = 98.35 ± 28.84; p = 0.38; d = 0.29) for the gift task. This study provides initial evidence that early participation in a music enrichment program may benefit later development of EC. This study is registered at ClinicalTrials.gov (NCT02936284).
