Study: NCT05162781

Intervention type: BEHAVIORAL
Group type: ACTIVE_COMPARATOR
Intervention: Speed of Processing Training
Description: This training component targets cognitive processing speed, i.e., how quickly individuals process information that they receive through their senses. Cognitive processing speed is thought to be a basic capacity of the brain that underlies several other cognitive functions. Training is implemented using a web-based computer game, in which participants are required to fixate on a target at the center of the screen and identify targets in the periphery. The game is made progressively more difficult, in small increments, as participants gain mastery by increasing the speed at which targets are presented and increasing the number of distractors.

Group type: EXPERIMENTAL
Intervention: Instrumental Activities of Daily Living In-lab Training
Description: The training component is thought to bridge SOPT training, which targets a basic cognitive capacity, and IADL performance in daily life. This training component will involve repeated trials in which participants will practice carrying out simulated IADL tasks in the lab under the supervision of the trainer. The training will follow shaping principles, i.e., task requirements will be made progressively more challenging, in small increments, as participants gain mastery. Frequent, positive feedback will be provided.

Intervention: Cognitive Transfer Packagke
Description: This training component is designed to transfer improvements in cognition from the treatment setting to everyday life. Elements of this package include negotiating a behavioral contract about the roles of the participant and family caregiver in the treatment, monitoring behavior outside the lab, and assigning performance of IADL as homework.

Intervention: Family Caregiver Coaching
Description: One or more family members of the participant will receive coaching on how to best support the participant in carrying out the in-home components of the intervention.
