Extended Access Addition-like Behavior. Figure 2A. Mean (+/−SEM) number of licks/5 min of 0.15% saccharin over 16 trials for saline, small, and large suppressors. Mean (+/−SEM) number of saline or heroin (.06 mg/0.2ml of heroin) infusions/6 h (Figure 2B) and within in the 1st h (Figure 2C) across 16 trials for saline, small, and large suppressors. Figure 2D. Percent goal directed behavior shown for Trial 1 and Terminal Trial 16 for saline, small, and large suppressors. Figure 2E. Mean (+/−SEM) number of saline or heroin infusions earned during progressive ratio testing for saline, small, and large suppressors. Figure 2F. Mean (+/−SEM) number of drug seeking behaviors/1 h exhibited during the 6 h extinction and 1 h heroin induced reinstatement tests for saline, small, and large suppressors. *p<0.05: large suppressors vs. small suppressors; #p<0.05: large suppressors vs. the saline controls; $p<0.05: small suppressors vs. the saline controls.
