Description of intervention(s) / exposure
Behaviour - Perceptual-based memory encoding
Behaviour - Semantic-based memory encoding
Behaviour - Cognitive stimulation

Experimental: Perceptual-based memory encoding - It will involve the use of visual imagery and the method of loci. To achieve this, each of the 15 daily tasks will be filmed and a short video created. In addition, each task will be broken down into 5-6 photographed steps based on activity analysis and task breakdown. The program will prompt the user to indicate in which room of the house the task would usually be completed. Once correct location is identified, the program will prompt the user to watch a chosen daily task video and then visualise themselves completing the task in their home environment.

Experimental: Semantic-based memory encoding - It will incorporate association-based strategies to assist with recalling the steps of daily tasks. The steps of a given daily task will be provided and the user will be prompted to link the steps using a honeycomb concept, which makes use of the chunking method to encode the sequenced steps. Following this, the program will prompt the user to categorise the steps according to their association with given words cues. The word cues will represent time, places, objects, and people. The program will then take the user response and form a verbal and visual story according to the responses given. The program will help identify any problems in the sequencing and prompt the user to re-categorise if required.

Active Comparator: Cognitive stimulation - Participants will complete an online cognitive exercise program, Lumosity (Sarkar, Scanlon, & Drescher, 2007). A study conducted by Hardy, Drescher, Sarkar, Kellett, and Scanlon (2011) indicated that participants who engaged in Lumosity showed greater improvements in memory in comparison to a non-intervention control group.


Behaviour: Perceptual-based memory encoding
It will run for 12 weeks with a 1-hour training session each week, supervised by a rehabilitation professional.
In addition, two 30-minute home-based training sessions will be completed by participants. In the home training session, participants will practice specific daily tasks that are covered in the previous professional-led session through the use of the computer-based intervention.

Summary
Brief summary
This study will adopt a newly developed computer-based cognitive rehabilitation program
targeting the encoding stage of memory. The aims of the study are:

1. To test the feasibility of conducting a newly developed computer-based cognitive
rehabilitation program for healthy older adults, people with MCI and mild dementia.

2. To test the effectiveness of the newly developed program in improving cognitive function
and enabling maintenance of occupational performance in healthy older adults, people
with MCI or mild dementia.

Using an iPad application, study participants will learn a memory encoding strategy to
support completion of their daily activities. By implementing memory encoding strategies
during the mild stages of cognitive decline, the project aims to prolong independence in
functional performance. It is anticipated that adoption of the same memory strategies will
enable maintain performance as they may experience ongoing cognitive decline.
