Findley, a law clerk in an Arizona juvenile court, and Sales (criminal justice, Indiana U.-Bloomington) critically review the scientific support for the advocacy recommendations by trial commentators, and identify the limitations on these recommendations. They use research that directly addresses the matter, and also research that was conducted for other purposes but sheds light on the issues of trail advocacy. They discuss an attorney's demeanor, verbal communications, paralinguistic communications, kinesic communications, relationship with the client, and storytelling.
