Stimulus sequence, Experiments 2a, 2b. a: Experiments 2a and 2b were identical to Experiment 1, save for the addition of the second adaptor on each trial, as shown. There was always one happy and one sad adaptor presented during each trial and the hemifield they were respectively presented in varied randomly on a trial by trial basis. b: Experiment 2b varied the location of the saccade cue (red dot, on or near the cued target face), rather than locking it to the center of the adaptor, as in Experiment 1a–c and 2a.
