The role of spatial frequency information for ERP components sensitive to faces and emotional facial expression [PDF]
, 2005 To investigate the impact of spatial frequency on emotional facial expression analysis, ERPs were recorded in response to low spatial frequency (LSF), high spatial frequency (HSF), and unfiltered broad spatial frequency (BSF) faces with fearful or ...

EMPATH: A Neural Network that Categorizes Facial Expressions [PDF]
, 2002 There are two competing theories of facial expression recognition. Some researchers have suggested that it is an example of "categorical perception." In this view, expression categories are considered to be discrete entities with sharp boundaries, and ...
