“…This study investigated an approach that has not previously been reported with hyperactive children: correspondence training (Israel, 1978;Karlan & Rusch, 1982). Basic research in the area of correspondence training suggests that correspondence procedures can produce rapid changes in nonverbal (target) behavior by strengthening the appropriate verbal-nonverbal relationship (Baer, Williams, Osnes, & Stokes, 1984;Israel, 1973;Israel & Brown, 1977;Israel & O'Leary, 1973;Paniagua, Stella, Holt, Etzel, & Baer, 1982;Risley & Hart, 1968;Rogers-Warren & Baer, 1976;Williams & Stokes, 1982). Several investigators have emphasized the clinical effects of correspondence training (e.g., Baer, Osnes, & Stokes, 1983;Brodsky, 1968;Finney, Russo, & Cataldo, 1982;Jewett & Clark, 1979;Keogh, Burgio, Whitman, & Johnson, 1983;Paniagua, 1985;Wacker & Greenebaum, 1984;Whitman, Scibak, Buttler, Richter, & Johnson, 1982).…”
