Study type
Interventional
Description of intervention(s) / exposure
Group 1 is our intervention group and participants in this group will complete working memory game training. Participants will be able to complete their training via an already developed brain training website call the DREAM website. The website was developed by Professor Jan L. Plass of the New York University. Participants will be expected to complete their training online from the comfort of their home. The game is called 'CrushStations' and has similarities with the n-back task, a measure of working memory popularly used in working memory training research studies. The game is made adaptive which means that difficulty level is increased based on participant's performance. Participants will have different types and colors of sea creatures displayed on their screen to remember, and will be asked to recall the type and color of the sea creatures at a later recall test. Participants will be expected to train four days a week for six weeks altogether, and for twenty one minute in each sitting. To monitor adherence to the intervention, participants will be informed via a Plain Language Statement and Consent Form that the DREAM website will share their training information with the Deakin research team about how frequently they completed their training, including number of minutes spent completing training in each sitting, total number of days trained in a week, number of weeks trained altogether and levels completed altogether.

Comparator / control treatment
Group 2 is our active control group. Participants in Group 2 will complete mindfulness training online via the Mindfulness Coach Explorer app. Participants will be asked to listen to recorded guided meditation that facilitates open monitoring of thought processes and promotes acceptance and awareness of thoughts and emotions. Through the recorded meditation script, participants will also practice focused attention meditation where they will be guided to bring their attention on an object such as their breath, and as their mind wanders to distracting thoughts, they will be gently guided to bring their awareness back to their breathing, nonjudgmentally and in an accepting manner. Participants will be expected to train for 21 minutes in each sitting, for 4 days a week and for 6 weeks altogether. Participants consent in Plain Language Statement and Consent Form that the Mindfulness Coach Explorer App will share their training information of research participants with the with the research team. This information includes number of minutes trained in each sitting, number of minutes trained each week, and number of weeks trained altogether.
