…An international group of experts has carried out an in-depth study into how we process emotional expressions, looking at the pattern of cerebral asymmetry in the perception of positive and negative facial signals…
The results, published in the latest issue of the journal Laterality, show that the right hemisphere performs better in processing emotions. “However, this advantage appears to be more evident when it comes to processing happy and surprised faces than sad or frightened ones”, [study co-author J. Antonio Aznar-Casanova] points out.
“Positive expressions, or expressions of approach, are perceived more quickly and more precisely than negative, or withdrawal, ones. So happiness and surprise are processed faster than sadness and fear”, explains Aznar-Casanova.
This research study adds to previous ones, which had revealed asymmetries in the way the brain processes emotions, and enriches the international debate in cognitive-emotional neuroscience in terms of how to define the exact way in which human beings process these facial expressions.
