Yuri Rassovsky, Junghee Lee, Poorang Nori, Allan D. Wu, Marco Iacoboni, Bruno G. Breitmeyer, Gerhard Hellemann and Michael F. Green Assessing temporal processing of facial emotion perception with transcranial magnetic stimulation Brain and Behavior 3
This project was an effort to understand how the speed of facial emotion processing varies as a function of spatial frequency composition of facial stimuli. Results indicate that although low spatial frequency information is generally more important than high spatial frequency (HSF) information for emotional processing, both low and HSF filtering reduced the speed of extracting emotional information from faces. It appears that intact faces rely primarily on fast feedforward mechanisms for emotional processing, whereas filtered faces can no longer effectively process emotional information without re entrant feedback from higher areas of the brain.
