**An 11-month-old infant from Experiment 2 watches an unexpected outcome in the *Efficient-Agent Task*.** Before seeing this test trial, the infant saw eight familiarization trials in which the orange agent moved efficiently around obstacles in the grid world to its goal, the blue object. Here, that agent is taking an inefficient path to its goal, and the infant exhibits surprise (looks longer) to this outcome compared to an outcome in which the agent takes a novel, but efficient path.
