“…As well as its development, researchers have explored a variety of different aspects of children’s private speech, including its relations with children’s task performance and on-task behavior (Berk, 1986; Fernyhough & Fraley, 2005; Winsler, Diaz, & Montero, 1997); task and setting influences on such speech (Fuson, 1979; Winsler, Carlton, & Barry, 2000); its use among children with behavior, learning, and/or attention problems (Berk & Landau, 1993; Ostad & Sorensen, 2007; Winsler, 1998); and task-related utterances to self during problem-solving processes (Winsler, Feder, Way, & Manfra, 2006). It is the last aspect—task-related private speech during problem solving in mathematics—that will be the main focus of the present study.…”
