Virtual Corridor Navigation Task (IMAGE)
Caption
Virtual corridor navigation task. Illustrated on the top (1) are example frames from a right-turning corridor animation. At the end of each corridor, navigators were presented with a screen showing different arrows, and had to choose which one they thought pointed to the beginning of the corridor. (2) is a schematic of the possible corridor turns, including the eccentricity of the turn relative to the heading defined by the initial segment (?120°, ?90°, ?45°, 45°, 90°, 120°). The top-view head representations in (3) illustrate cognitive headings based on Allocentric (A) and Egocentric (E) frames during a right-turning (90°) corridor. Note that using an egocentric strategy will lead participants to perceive the corridor start behind them and to the right, so they would choose the right pointing arrow. Conversely, using an allocentric frame a participant would choose the left arrow in the same scenario, because their cognitive heading remains the same throughout the trial, and matches the heading of the initial corridor segment.
