Cognitive Multi-Tasking Training in Healthy Older Adults

Not Applicable

Completed

Brief Summary: This study evaluated the feasibility of a remote web-based ecological cognitive training protocol to healthy older adults. The training protocol involves 5 training sessions.

Detailed Description: Previous research demonstrated the relevance in training cognitive abilities that typically decline with age, such as those associated with executive control (e.g., abstract thinking, selective and divided attention, planning, task-switching and inhibitory control). The aim of the present study is to investigate the feasibility of a web-based cognitive training focused on executive control to cognitively healthy older adults. The participants will undergo the web-training in a daily type situation of meal preparation (i.e., Breakfast Game). The training protocol combines the tasks of table setting and cooking in a multi-tasking fashion. In some sessions Emphasis Change approach will be apply to the training, in order to assess it feasibility and potential effects in optimizing the performance. In addition, participants will undergo a brief web-based cognitive evaluation before and after training. If feasible, the investigators protocol will allow training older adults in critical cognitive skills for daily life situations. The web-based training is an advancement since it can be delivered at-home, remotely supervised, and is easily scalable. Recently, remote interventions have been particularly relevant to older adults due to the COVID-19 pandemic, which may limit in-person research participation.

Recruitment & Eligibility

Inclusion Criteria

Exclusion Criteria

Low test scores (below 26 on the Montreal Cognitive Assessment - MoCA)

Subjects which English is not the primary language, or with lack of capacity to consent will not be enrolled.

Arm && Interventions

Group	Intervention	Description
Computerized Cognitive Training (Breakfast Game)	Multi-tasking Training	Participants will undergo a pilot training protocol where they will have to perform two tasks concomitantly, in a multi-tasking fashion. The tasks are related to everyday activities as "cooking" and "setting tables".

Primary Outcome Measures

Name	Time	Method
Change in Cooking Time Discrepancy Scores	Up to 3 weeks	Change in cooking time (milliseconds) in each food type. In the computerized task, participants are asked to cook different food types. Scores reflect the average absolute values of the difference between the required and actual cooking time of each item. Lowers scores (closest to zero) represent a better outcome.
Change in Range of Stop Times Score	Up to 3 weeks	Change in cooking time (milliseconds) between food items. In the computerized task, participants are asked to cook different food types. Scores reflect is the difference between the first and last food item stopped cooking. Lowers scores (closest to zero) represent a better outcome.
Change in the Number of Tables Set Score	Up to 3 weeks	Change in the total number of tables set. In the computerized task, participants are asked to set tables for four guests, when finished, one point is given. Higher scores represent a better outcome.

Secondary Outcome Measures

Name	Time	Method
Post-training feasibility questionnaire	Within one week after the intervention	Questionnaire assessing participant´s opinions about performing the web-based training based on Breakfast Game (e.g., difficulty, satisfaction). Higher scores reflect feasibility of the intervention.
