The study involves playing a working memory training program, completing a few cognitive tests and filling out some questionnaires. In total you will be asked to complete a Participant Questionnaire and then 22 assessment and training sessions (20-30 min each). All sessions can be completed at home on your own tablet or smartphone, and we ask you to do so in a quiet environment. We ask that you complete 2 sessions a day and to complete at least 10 sessions a week. The main study can be completed in 11 business days! Then you will be reminded to complete a short follow-up session 3 months later. Upon completion of the study, you will be entered into a monthly Grand Prize drawing for a chance to win a brand new iPad (10.2 Retina display with 32 GB of storage) or a gift card valued $20-100. You will also earn entries into a weekly give-away for a chance to win $5 or $10 gift cards. Entries are given for each completed session and these will be confirmed in weekly e-mails. Odds of winning depend upon the number of eligible entries. The giveaway is only open to legal residents of the United States.
