The goal of this clinical trial is to learn if engaging with an digital intervention may improve cognitive function. The main questions it aims to answer are:

1. Does engagement in with a digital intervention improve working memory?
2. Does engagement in with a digital intervention improve inhibitory control?

Researchers will compare two different digital interventions to assess whether they may be helpful in improving cognitive function.

Participants will conduct study activities remotely (e.g., at-home):

1. Baseline Assessment. Complete a series of cognitive assessments and surveys.
2. Intervention. Engage in a digital intervention for up to 8 weeks.
3. Post Intervention Assessment. Complete the same cognitive assessments and surveys as the Baseline Assessment.
4. Follow-Up Assessment. Six months after the intervention ends, participants will complete the same cognitive assessments and surveys as the Baseline Assessment.

During the Baseline Assessment, participants will complete web-based cognitive assessments and surveys. The assessments will address various cognitive functions including working memory, long-term memory, inhibitory control, and sustained attention. Surveys will include a characterization of expectancy for the intervention, ratings of stress, and background health information. The Baseline Assessment will take up to 120 minutes and can be completed across more than one session.

During the Intervention, participants will be provided an iPad tablet to engage with the assigned intervention app. Participants will be randomly assigned to one of two intervention apps. Regardless of the assigned intervention, participants will engage with the app for 25-45 minutes of training per day, 5 days a week for up to 8 weeks for a total of 1000 minutes of training.

After the intervention, participants will complete a Post Intervention Assessment and 6 month later, a Follow-Up Assessment. Both of these assessment periods will consist of the same cognitive assessments and surveys as conducted during the Baseline Assessment.

Upon completion of all study activities, participants will be able to keep the iPad as a gift for their voluntary participation.
