Facial Expression Aftereffect Revealed by Adaption to Emotion-Invisible Dynamic Bubbled Faces
Fig 2
Trial sequence for the static emotion-unrecognizable adaptation condition in Experiment 1.
Example is condition “SU”. Subjects fixated on the cross and pressed the space bar to initiate a trial block. After 506 ms, the adapting face appeared for 4 s. After a 506 ms inter-stimulus-interval (ISI), a test face appeared for 200 ms. A beep was played to remind subjects to press the appropriate key to report a happy or sad expression of the test face. In actual experiments, the fixation cross was always at the center of the screen.
