Does prosody make the difference? A meta-analysis on relations between prosodic aspects of infant-directed speech and infant outcomes

Many limitations in the existing body of literature were found, such as a lack of empirical papers exploring IDS prosody in relation to infant outcomes using natural observations. The results and limitations were discussed in light of the necessity to examine the interplay between the quality of IDS prosody and other aspects of parental communicative and caregiving competences. To do so, the contribution of scholars from different fields is needed with the aim to fully understand the multidimensional determinants and influential mechanisms of IDS.
