Navigation Task
This study explores how playing a computer game affects memory formation and retrieval. The game is set up as an experiment where players learn the rules on their own. The task is presented on a monitor for the patient which is positioned to suit the patient’s height and seating arrangement. Before they begin, players receive specific audio cues. First, the participant will navigate between two areas (arms of a circle maze), where they will be presented with two colored circles. The participant navigates to one of the corridors, and then they will receive audio feedback, indicating if their choice was right or wrong. The feedback tones vary and the participant will know beforehand which tone represents a correct answer. Therefore, based on the sound feedback, each time the participant chooses a colored object, it is revealed whether their decision was correct or incorrect. The participant has unlimited time to figure out the rule through trial and error. When the participant believes they understand the rules of the game, they will inform the researcher, (without telling them the rules) and then play more trials. This task ranges from 20 minutes to 1 hour. This task can run at any time during iEEG recordings.
