“…Likewise, making teacher attention contingent upon the individual behaviors of all students in a classroom has been reported to increase the rate of study behavior (Hall, Panyon, Rabon, and Broden, 1968;Kazdin and Klock, 1973), to decrease the rate of disruptive behavior (Hall, Fox, Willard, Goldsmith, Emerson, Owen, Davis, and Porcia, 1971;Madsen, Becker, Thomas, Koser, and Plager, 1968;McAllister, Stachowiak, Baer, and Conderman, 1969), and to increase the rate of following instructions (Schutte and Hopkins, 1970). Finally, the use of individually administered token reinforcers for whole classes has been reported to increase the rate of study behavior and academic performance (Bednar, Zelhart, Greathouse, and Weinberg, 1970;Bijou, Birnbrauer, Kidder, and Tague, 1966;Birnbrauer, Bijou, Wolf, and Kidder, 1965;Birnbrauer and Lawler, 1964;Bushell, Wrobel, and Michaelis, 1968;Chadwick and Day, 1971;Clark, Lachowicz, and Wolf, 1968;Ferritor, Buckholdt, Hamblin, and Smith, 1972;Glynn, 1970;Haring and Hauck, 1969;Hewett, Taylor, and Artuso, 1967;Knapczyk and Livingston, 1973;McIntire, Davis, and Pumroy, 1970;McKenzie, Clark, Wolf, Kothers, and Benson, 1968;McLaughlin and Malaby, 1972a;Nolen, Kunzelmann, and Haring, 1967;Wolf et al, 1970;Wolf, Giles, and Hall, 1968;Zimmerman, Zimmerman, and Russell, 1969) and to decrease the rate of disruptive behavior (Ayllon and Roberts, 1974;Broden, Hall, Dunlap, and Clark, 1970;Drabman, 1973;Drabman, Spitalnik, and O'Leary, 1973;Kuypers, Becker, and O'Leary, 1968;…”
