Whereas in the study of language we have relatively explicit theories of
the relevant primitives (phonemes, morphemes, words, etc.), in the study
of face perception the ontology remains coarse and without strong
theoretical grounding. We know that face perception involves processing
individual features and global configuration, but it is unclear whether
these are the critical primitive components of face processing. Aiming to
replicate and extend Liu, Harris & Kanwisher (2002), we recorded MEG data
while subjects passively viewed upright and inverted faces: normal,
intact-configuration (features blurred out), and intact-features
(features rearranged). Our results suggest that it is optimistic to
expect a direct mapping between component subtype in face processing and
visually-evoked fields, and that we need a more nuanced model.
