Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The present study investigates how individual differences in cognitive processing contribute to the efficacy of working memory training programs in an older adult population. In a randomized crossover design, different types of working memory training interventions will be evaluated within the same participants.

Adding game-like elements to working memory training programs can increase motivation and engagement, which can increase learning. However this process, termed gamification, adds sensory complexity that can lead to increased mental load and/or distraction in older adults. Investigators hypothesize that gamification of training tasks will be beneficial to some and counterproductive to other participants. The investigators will test two models; the first assumes that participants with difficulty inhibiting distracting information will show better learning and transfer when assigned to non-gamified training, whereas those with more distractor tolerance will show better learning and transfer when assigned to gamified training. The second model states that the outcomes of the intervention will be better predicted by performance on measures of general cognitive ability.

In a separate study, the investigators will compare working memory training that contains rich, multisensory information with a training program that contains only visual information. Here they will also test two models; the first assumes that participants with difficulty binding two stimulus streams will show better learning and transfer when assigned to visual-only working memory training, whereas participants who do not have this difficulty will show better learning and transfer when assigned to multisensory working memory training. The second model states that the outcomes of the intervention will be better predicted by performance on measures of general cognitive ability.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Three randomized cross-over trials will be conducted to obtain within-subject comparisons of training with enriched (game-like) versions of working memory training tasks compared to basic (non-gamified) versions of these tasks. In the N-back trial, participants will be assigned to Non-Gamified N-back training and Gamified N-back training. In the Span trial, they will be assigned to Non-Gamified Span training and Gamified Span training and in the Multisensory trial, they will be assigned to Non-gamified Unisensory N-back training and Non-gamified Multisensory N-back training.

Each trial involves a total of 50 sessions per participant: the first few sessions consist of completing questionnaires and computerized cognitive assessments (pre-test). Participants then complete 20 sessions of working memory training. After a mid-test, they complete 20 sessions of a different type of working memory training. Post-test is administered upon training completion, and at least a month later, participants complete 3 follow-up sessions. The study can be administered either in person or remotely; however, the investigators anticipate that most participants will complete the study remotely.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

Three randomized crossover trials (N-back, Span and Multisensory) will be conducted and in each trial, participants will be randomly assigned to 1 of 2 conditions: Condition 1 consists of training type 1 followed by training type 2, whereas Condition 2 consists of training type 2 followed by training type 1. In the N-back trial, participants will be assigned to Non-Gamified N-back training and Gamified N-back training. In the Span trial, they will be assigned to Non-Gamified Span training and Gamified Span training and in the Multisensory trial, they will be assigned to Non-gamified Unisensory N-back training and Non-gamified Multisensory N-back training.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Condition 1

Training type 1 will be administered in the first part of the crossover trial and Training type 2 will be administered in the second part of the trial. Each training part consists of 20 twenty-minute long sessions with the recommended frequency of 2 sessions per work day. Thus each training part can be completed in 10 work days (2 weeks).

Group Type ACTIVE_COMPARATOR

N-back

Intervention Type BEHAVIORAL

The training program is a personal device-based adaptive version of a visual N-back task, either devoid of game elements or embedded in a gamified platform game

Span

Intervention Type BEHAVIORAL

The training program is a personal device-based adaptive version of a visual working memory span task, either devoid of game elements or embedded in a gamified platform game

Multisensory

Intervention Type BEHAVIORAL

The training program is a personal device-based adaptive version of an N-back task that features visual stimuli (Unisensory) or visual stimuli paired with unique sounds (Multisensory) and is devoid of game elements

Condition 2

Training type 2 will be administered in the first part of the crossover trial and Training type 1 will be administered in the second part of the trial. Each training part consists of 20 twenty-minute long sessions with the recommended frequency of 2 sessions per work day. Thus each training part can be completed in 10 work days (2 weeks).
