Study type
Description of intervention(s) / exposure
The Focus Pocus (version 2) neurocognitive training software was developed by NeuroCog Proprietary Limited incorporating intellectual property licensed from UOW. The software consists of a series of wizard-themed, computerised, mini-games targeting inhibitory control (IC), working memory (WM) and state control (SC). During use of the software, participants are required to wear a portable EEG headset; the NeuroSky MindWave. The headset records EEG from a single, dry, sensor resting on the forehead referenced to an ear-clip electrode.

During SC games, participants are instructed to ‘focus’, ‘relax’ or induce a state of ‘zen' (i.e. focused and relaxed), and the corresponding EEG pattern is used to control elements of the game (e.g. the speed of the player in a broomstick race). During WM and IC games, EEG is passively monitored and categorised according to attention level during the game, with attention level then used as a multiplier for game points. Game difficulty adapts constantly based on performance to ensure that games are challenging but not too difficult. Participants receive on-screen feedback about performance following each game.

In the present study, participants will be required to complete 25 sessions of the neurocognitive training, at a rate of 5 sessions per week. Each training session will consist of 6 SC, 4 WM, and 4 IC games, and will take approximately 20 minutes to complete. Participants will self-administer the training in their own homes, using their own personal computer or iOS device and a loan headset. Data regarding training compliance and performance will be sent to an online server, so that researchers can monitor progress.

Brief summary
The primary purpose of the study is to assess the efficacy of a neurocognitive training program for improving executive function and arousal state modulation in adults with traumatic brain injury. It is expected that compared to a waitlist control, those who complete the training will show improvements on a rang of cognitive and behavioural measures of executive function, as well as improvement in their ability to regulate arousal state of the brain (brain activity measured by EEG).
