Stimuli in Experiment 3. A set of faces was morphed from happy to sad to angry and back to happy again to create a “circle” of facial expression. After viewing a sequence of faces (similar to Experiment 2, see methods in Experiment 3 for details), observers saw a single test face they adjusted to match the mean expression of the previously displayed set.
