<qa>  How many formal training sessions will participants attend each week?To reduce bias, all assessors will be blinded to group allocation of participants. Participants will be randomly assigned to one of the three groups i.e., FBT, Ex-FBT, or SCT. Participants in the FBT group will be required to attend 3 formal training sessions per week, for 8 weeks, at the Djavad Mowafaghian Centre for Brain Health or the Centre for Hip Health and Mobility. Each session will be for 60 minutes. Additionally, the participants will be asked to complete 3 additional one-hour training sessions at home per week. Thus, the participants will complete a total of 48 hours of cognitive training over 8 weeks.
