Week 4

In the fourth week, participants are asked to take on all three scenarios in sequence, as they would in a real-life travel situation (prospective working memory, planning/execution, and long-term memory). Week 4 serves two purposes. First, it demands greater cognitive flexibility upon participants. Second, it emulates an extended task sequence that one could encounter in daily life (pack for a trip, navigate to a location, and visit a destination). This final week may serve as an important indicator of overall success and performance in week 4 may be most predictive of gains on outcome measures.

Participants will be excluded from further participation if they fail to meet the assigned time on the simulations for any given week. We will afford participants an opportunity to pick up on simulation play the following week, but if they do not meet the 5-h criterion we will move to exclude them. If participants are unable to carry out the activities in any of the weeks of the intervention (or are unwilling to), we will discontinue their enrollment. We will make efforts to retain all enrolled participants by reaching out (at least two times per week during the intervention) to ensure that they understand the intervention and are able to complete it. We will also reach out via email and texting if participants are comfortable with those methods.
