Participants viewed images of virtual scenes with a cylindrical volume of liquid positioned above randomly generated obstacle courses and predicted what fraction of the liquid would flow into the right basin below the obstacles. Participants were randomly assigned to predict the behavior of either a water-like liquid (Experiment 1a) or a honey-like liquid (Experiment 1b). During a practice phase, participants received video feedback showing the liquid flowing. The main test phase consisted of 120 trials without feedback.
