OverviewAI-generated summary
R Landes, a Research Assistant in Biostatistics at the University of Arkansas for Medical Sciences College of Medicine, has focused research efforts on understanding the relationship between cognitive processes and substance abuse treatment outcomes. Their work has explored how factors like working memory and delay discounting influence treatment success in individuals with stimulant addiction and opioid dependence. Landes has also investigated predictors of tobacco dependence treatment outcomes, particularly within lower socioeconomic groups, examining the roles of delay discounting, locus of control, and cognitive impulsiveness. Their research has been published in peer-reviewed journals, with publications dating from 2000 to 2014. Key collaborators include Pearman D. Parker, C. Barone, and T Bogan, all affiliated with the University of Arkansas for Medical Sciences.
