“…Studies focused on maintenance indicate that it is possible to maintain correspondence by simply reinforcing the verbalization (Baer, Blount, Detrich, & Stokes, 1987;Baer, Williams, Osnes, & Stokes, 1984;Guevremont, Osnes, & Stokes, 1986b;Osnes, Grevremont, & Stokes, 1986;Paniagua & Black, 1990;Ward & Stare, 1990;Whitman, Scibak, Butler, Richter, & Johnson, 1982) or through intermittent reinforcement of the correspondence (Baer et aI., 1987) and indiscriminable or almost random contingencies (Guevremont et aI., 1986b). Research into the generalization of say-do correspondence has suggested that a number of variables may be involved in promoting successful generalization (Guevremont et aI., 1986a;Rogers-Warren & Baer, 1976;Whitman et aI., 1982).…”
