Enhancing parent language interactions with children beginning in infancy is important because it results in better language abilities, social skills, and academic outcomes in children. A number of researchers have suggested that parent language interactions with children could be enhanced by giving parents feedback about their language interactions using the Language Environment Analysis (LENA) system. The LENA system records communication exchanges between a child and the adult caregiver and provides an automated analysis of adult word count, child vocalization count, and conversational turn count. We did a systematic review of the studies that investigated the use of LENA-based feedback to enhance parent language interactions with children. Although most previous studies have concluded that LENA-based feedback improves parental language interactions with children, methodological factors and confounding of treatment components in almost all of these studies make it impossible to know whether quantitative feedback from interactions recorded by the LENA system enhances parent language interactions with children. The designs and results of previous studies are discussed to suggest how future research can better address this important issue.
