Child word learning in song and speech

Area of Science:

• Developmental Psychology
• Cognitive Science
• Music Cognition

Background:

• Previous research indicates that music aids word learning and memory in adults and older children.
• The developmental trajectory of this music-based learning advantage in early childhood remains less understood.

Purpose of the Study:

• To investigate the impact of sung versus spoken words on word learning and long-term memory (LTM) in young children.
• To examine developmental changes in the reliance on musical features for word acquisition.

Main Methods:

• An intermodal preferential looking paradigm was used to assess word learning (word-object associations) in 1- to 4-year-olds.
• Long-term memory for learned words was assessed in 4- to 5-year-olds several days post-learning.
• Children were exposed to novel words presented in either adult-directed speech (ADS) or sung format.

Main Results:

• Sung words led to significantly better word learning than ADS words across all age groups (1- to 2-year-olds, 3- to 4-year-olds, and 4- to 5-year-olds).
• 1- to 2-year-olds exclusively learned sung words, while 3- to 4-year-olds learned both sung and ADS words, indicating a developmental decrease in music reliance.
• 4- to 5-year-olds demonstrated reliable long-term recall of sung words but not spoken words, with the benefit stemming from initial learning exposure.

Conclusions:

• Music provides a robust benefit for word learning and recognition in young children, evident from 1 year of age.
• While reliance on music for initial word learning decreases with age, sung words continue to show advantages for long-term recall in preschool-aged children.
• The observed benefits of song on word learning and memory are not attributable to attentional effects alone.
