Influence of Activity Type and Setting on Toddler Language Environment

Early childhood language environment has an important effect on developmental language outcomes. Intervention and parent training for children who have speech and language delays often focuses on the implementation of strategies designed to enhance the language environment. With quantitative information on different aspects of the language environment, intervention and parent training can be better tailored to the needs of each child and can be made easier for parents to implement. This study uses the Language Environmental Analysis (LENA) system to explore differences in language environment across participants, settings (toddler group and home), and activities (general, outside, and organized playtime, story time, meal time, naptime, transition, public outside visits, travel time, TV time, personal care, and other). Participants were five children, ages 20-35 months who had speech and language delays. The children wore the LENA for one day and the adult words to the child, child vocalizations and turn-taking were analyzed during each activity and setting. We found that general and outside playtime activities, meal time, and personal care times were activities that consistently resulted in high levels of child vocalization across participants. Structured play and story time did not result in high levels of child vocalization. We also found that, for some children, there were differences in the quantity of adult language addressed to the child in language group and home settings. These findings have implications for training parents to provide language rich environments for their child.
