2.4. NeuroDRIVE intervention

The NeuroDRIVE intervention consisted of six 90-minute sessions (9 hours total) conducted over a four-week period. Intervention sessions were designed to allow participants to practice driving skills as well as cognitive skills. Both the examiner and the automated system provided guidance and feedback throughout the session to assist the participant with improving their performance. A typical intervention session included the following key elements: 1) a brief review of training and progress thus far (or an introduction, for the first session); 2) practice of component cognitive skills such as dual processing, working memory, and response inhibition through the use of standardized cognitive driving scenarios; 3) practice of composite driving skills such as following the rules of the road and being vigilant for road hazards while simultaneously performing working memory or visual attention tasks; and 4) finishing with an open-ended race-track course to promote engagement in the process and to allow participants to safely “test the limits” of their skills in a simulated environment. Early sessions focused on fundamental, basic skills, and later sessions incorporated more complex, higher-order skills. Difficulty was also modulated by the examiner in each activity to match the skill level of the participant.
