CogT pSOPT Intervention Study

(JUSTIFICATION: This is the R33 stage of an NIH funded R21/R33 study. R21 stage (IRB-61727) was focused on intervention development; R33 stage will focus on pilot testing the effect of the intervention. The R21 phase was not considered a NIH defined clinical trial; R33 will be considered a NIH defined clinical trial) The purpose is to develop and test the effect of a \"personalized\" computer-based cognitive training program. The personalized program tailors the difficulty of the training tasks using a participant\'s biofeedback (i.e., heart rate) and cognitive performance. Such a personalization will ensure that the participant can perform at his/her ideal training capacity. Participants will be randomized into one of 2 groups and each group will play a different version of computerized training game and have ECG collected to allow subject blinding.
