Participants exhibit passive avoidance of the CS+ in VR following de novo fear conditioning. (A) Participants searched for an escape platform in two VR pool contexts. Each pool snapshot shows a view of the southwest (SW) quadrant from a northeast position, with the CS+ present (test pool) or absent (control pool). Participants were instructed that shocks were possible during the navigation task, but none was actually administered. (B) Aerial views of search paths taken by three participants depicting variable amounts of search bias in the test pool (2.3%, 13.3%, or 30.1% time spent in the SW quadrant). The approximate location of the CS+ on the surrounding walls is indicated. (C) In the test pool, participants spent less time searching in the SW quadrant and took longer to first enter the SW quadrant of the test pool relative to the control pool. (*) P < 0.05. Error bars are SEM.
