The goal of the study is to understand how well cognitive training improves reaction time in people with head and neck cancer (HNC). Aim 1. Evaluate the preliminary clinical effectiveness of a 10-week home- and video game-based SOPT on cognitive functioning and driving performance in HNC survivors. This study will include completing five questionnaires and simulated driving in a simulator at two different times, 10 weeks of participating in 2 sessions per week of video-game cognitive training at home and being interviewed once at the end of the 10-week training.
