“…Results of numerous basic studies have shown that prior experience with the punishing stimulus either contingently or noncontingently can decrease a behavior's sensitivity to punishment (e.g., Capaldi, Sheffer, Viveiros, Davidson, & Campbell, 1985;Halevy, Feldon, & Weiner, 1987). For example, research findings with rats indicate that exposure to intermittent punishment with shock decreases the efficacy of continuous punishment with shock, even when several days or weeks lapse between intermittent and continuous punishment (Banks, 1967;Halevy et al;Shemer & Feldon, 1984). Deur and Parke (1970) replicated this effect with normally developing children and a loud buzzer as the punishing stimulus.…”
