Carlos Aparicio

Dr. Aparicio completed his Ph.D. in (1992) at the University of New Hampshire in the Experimental Analysis of Behavior. Since then he has been serving as an associate and full professor at multiple universities including University of Mississippi (1992-95), University of Guadalajara (1998-2007), University of North Carolina Wilmington (2007-2009), George Mason University (2010), and Savannah State University (2010-13). In addition, he was the Head of Research at The Aurora School at the Arc of Loudoun. He came to Salem State as an associate professor in 2013 and in 2016 was promoted to full professor in the Department of Psychology, where he is responsible of the Laboratory for the Experimental Analysis of Behavior in nonhuman animals.

For several years, I have been implementing current procedures in experimental analysis of behavior to assess the effects of dopamine agonists and dopamine antagonists on choice, impulsive behavior, self-control, temporal discrimination, and performance on progressive schedules of reinforcement. The use of mathematical models to fit the data and estimate the sensitivity of behavior to drug effects is the common denominator in all procedures implementing single-subject experimental designs, resulting in contributions to the experimental analysis of behavior.
