Children's language abilities predict success in remote communication contexts.

Remote communicative contexts are part of everyday social, familial, and academic interactions for the modern child. We investigated the ability of second-graders to engage in remote discourse, and we determined whether language ability, theory of mind, and shy temperament predicted their success. Fifty 7-to-9-year-old monolingual English speakers with a wide range of language abilities participated in standardized testing and an expository discourse task in which they taught two adults to solve the Tower of London, one in an audiovisual condition to simulate video chat and a second in an audio-only condition to simulate phone communication. The discourse was scored with a rubric of 15 items deemed relevant to the explanation. Children included 27% to 87% of the items, with more items communicated via gesture than spoken word in both conditions. Gesture scores and spoken scores were highly correlated. Children specified more rubric items overall in the audio condition and more rubric items in the spoken modality when in the audio condition than the audiovisual condition. Performance in both conditions was positively associated with scores on independent measures of language ability. There was no relationship between performance and theory of mind, shy temperament, ability to solve the Tower of London, age, or sex. We conclude that 7-to-9-year-olds adjust the modality and content of their message to suit their remote partner's needs, but their success in remote discourse contexts varies significantly from individual to individual. Children with below-average language skills are at risk for functional impairments in remote communication.
