Summary
The purpose of this study is to examine the effects of a cognitive training program in persons with Human Immunodeficiency Virus (HIV) infection who have used cocaine. This study tests the feasibility and preliminary efficacy of a computerized cognitive training program to improve working memory and decrease impulsivity (delay discounting) among HIV-infected individuals.
