Recruitment and Retention Materials for Longitudinal Studies on Early Prosodic Development

This dataset contains recruitment and retention materials developed for two longitudinal studies investigating the role of visual information in early prosodic development, conducted as part of the NWO VICI project A Sound Start at Utrecht University. The studies examined Dutch-learning infants' and toddlers' learning of German prosodic phrasing and Turkish prosodic focus marking through repeated live exposure to a foreign language. The collection includes recruitment flyers, a promotional video, a PDF version of the recruitment landing page, email templates used for communication with participating families, and a participant communication roadmap. These materials document the recruitment and retention strategies employed in longitudinal developmental research involving young children and their caregivers.
