- Reinforcer magnitude attenuates: apomorphine's effects on operant peckingJonathan W Pinkston
University of Texas Health Science Center at San Antonio, San Antonio, TX 76205, USA
J Exp Anal Behav 98:273-82. 2012..The data are consistent with the literature on behavioral resistance to change and suggest that the effects of apomorphine may be modulated by prevailing stimulus-reinforcer relationships...
- Delay discounting in C57BL/6J and DBA/2J mice: adolescent-limited and life-persistent patterns of impulsivityJonathan W Pinkston
Department of Psychiatry, University of Texas Health Science Center at San Antonio, TX, USA
Behav Neurosci 125:194-201. 2011..The present findings suggest that B6 and D2 strains may be differentially suited to uncovering the biological mechanism of short-term and long-term patterns of impulsive behavior...
- Reinforcement magnitude modulation of rate dependent effects in pigeons and ratsBrett C Ginsburg
Department of Psychiatry, Auburn University, 226 Thach Hall, Auburn, AL 36849, USA
Exp Clin Psychopharmacol 19:285-94. 2011..Subsequent analysis of the rate-dependency data suggest the effects of reinforcement magnitude may be due to a diminution of drug-induced increases in low-rate behavior that occurs early in the fixed-interval...
- The potency of fluvoxamine to reduce ethanol self-administration decreases with concurrent availability of foodBrett C Ginsburg
Department of Psychiatry, Division of Alcohol and Drug Addiction, The University of Texas Health Science Center at San Antonio, San Antonio 78229, USA
Behav Pharmacol 23:134-42. 2012..The results demonstrate that the potency of fluvoxamine in reducing ethanol-maintained behavior depends on whether ethanol is available in isolation or in the context of concurrently scheduled food reinforcement...
- Examination of reinforcement magnitude on the pharmacological disruption of fixed-ratio performanceJonathan W Pinkston
Universityof Texas Health Science Center, Department of Psychiatry, San Antonio, TX 78229, USA
Exp Clin Psychopharmacol 17:237-46. 2009..The results give additional support to the notion that pharmacological disruptors may not behave in the manner predicted by behavioral momentum theory...
