Means and SDs of the first fixation probabilities for angry, happy, and pain faces vs. paired neutral faces both for pain patients and controls.
* p < 0.05.
Fig 2.
Means (± SE) of the absolute fixation durations for the three emotional stimulus classes (pain, angry and happy faces) compared to neutral faces over 4 epochs of 500 ms during stimulus presentation separately for pain patients and controls and for both groups combined.
Asterisks indicate significant differences.
