“…The rationale is that the child is the best contingency manager because she or he can deliver reinforcement immediately at all times and across all settings (Clement, 1973). Despite the logic of this hypothesis, only a handful of studies have investigated the generality of self-control interventions across persons (Fantuzzo & Clement, 1981;Fantuzzo, Harrell, & McLeod, 1979), settings (Burgio, Whitman, & Johnson, 1980;Drabman, Spitalnik, & O'Leary, 1973;Robertson, Simon, Pachman, & Drabman, 1979;Turkewitz, O'Leary, & Ironsmith, 1975;Varni & Henker, 1979), behaviors (Ballard & Glynn, 1975), and time periods (Arnold & Clement, 1981;Brownell et al, 1977;Felixbrod & O'Leary, 1974;Robertson et al, 1979). These studies differ from our investigation in that they were either conducted in contrived settings or the assessment of generalization was not the primary focus.…”
