Intervention group
The game-based intelligence test (developed by LTPA solution Co., LTD) with an “audio-visual interactive input interface device” and a “special training course application (APP) on a smart phone or tablet” provides a multi-domain cognitive intelligence system that was used to train experimental group’s memory, attention, and coordination. A research assistant first created an account with their progress being logged in the system database and visualised through charts, after which he selected the training category in the APP and operated the sound and light feedback module. The light feedback function was used to track the long-term effects of the training. The difficulty level of the game was adjusted from one to 10 depending on each participant’s abilities (e.g. reaction time). Based on previous study findings, the training programs in both groups were set to be performed two to three times a week for six to eight weeks [
