N-Back Working Memory Primary · Baseline to post test. Post test will occur approximately two weeks following baseline.

Change in working memory performance on the N back working memory MRI task from baseline to post test will be assessed. Post test will occur approximately two weeks following baseline. The N-back working memory task will be completed during the MRI scan at both baseline and post test assessments. Working memory performance will be defined as a composite of reaction time and accuracy for two back trials. Specifically Target Accuracy percent correct and average correct target reaction time in milliseconds. Percent changes were calculated for Target Accuracy and Reaction Time in the form of (pos

Sponsor's own description

The current study will investigate methods for enhancing cognitive training (CT) effects in healthy older adults by employing a combination of interventions facilitating neural plasticity and optimizing readiness for learning. A pilot randomized clinical trial will examine the individual and combined impact of pairing cognitive training with transcranial direct current stimulation (tDCS). A precision dosing algorithm will be used to determine the appropriate levels of current and location of electrodes to deliver current using tDCS.
