Social Influences on Sensorimotor Integration of Speech Production and Perception During Early Vocal Learning

United States120 participantsStarted 2022-10-12

Plain-language summary

The goal of this study is to investigate the role of social factors on speech learning, including production and perception, in infants ranging in age from \~7-18 months. Infants have either typical hearing or sensorineural hearing loss. The main prediction of the study is that social reinforcement will engender improvements in vocal learning above and beyond gains in hearing in infants with hearing loss. As part of this study: * The parent and infant engage in a free play session in the playroom while the investigator cues the parent to say simple nonsense words; * Infants hear playback of the same words during a second phase.
