Betty Hart Dies at 85; Studied Disparities in Children’s Vocabulary Growth

Betty Hart, whose research documenting how poor, working-class and professional parents speak to their young children helped establish the critical role that communicating with babies and toddlers has in their later development, died on Sept. 28 in Tucson. She was 85...At the time, a prevalent view was that poor children were essentially beyond help, victims of circumstances and genetics. But Dr. Hart and some of her colleagues suspected otherwise and revisited the issue in the early 1980s, beginning research that would continue for a decade. “Rather than concede to the unmalleable forces of heredity, we decided that we would undertake research that would allow us to understand the disparate developmental trajectories we saw,” she and her former graduate supervisor, Todd R. Risley, wrote in 1995 in Meaningful Differences in the Everyday Experience of Young American Children, a book about their findings, which were reported in 1992. more
