Improving Memory Performance by Applying Cognitive Training

The proposed study will test the efficacy of a cognitive training program to improve working memory in a sample of HIV-infected persons. Investigators will assign 40 HIV-infected adults with poor medication adherence to one of two conditions (20/group): the experimental cognitive training intervention or a control training condition. Participants will complete 12 training sessions across 10 weeks and will complete assessments at baseline and post-training. The specific aims are to: 1. Investigate the effects of the cognitive training intervention on working memory and delay discounting in HIV-infected persons. Hypothesis 1: Participants assigned to active cognitive training, compared to those in the attention-matched control group, will have greater improvements in working memory and reductions in delay discounting. 2. Characterize adherence to antiretroviral medications in this population and examine medication adherence after cognitive training. Hypothesis 2: Participants assigned to active cognitive training, compared to those in the attention-matched control group, will have greater improvements in medication adherence.
