  • In Phase 1, positive stimulus signaled a loss outcome and neutral stimulus signaled a no-loss outcome. In Phase 2, neutral stimulus signaled a loss outcome, and positive stimulus signaled a no-loss outcome. The t(34) and corresponding p values are based on a one-sample t test against the chance value (50%).
