Chen, Kao & Tyler (2007, Cerebral Cortex)

Faces from the FERET database,

filtered in a 4th-power Gaussian

aperture and normalized to the full contrast range

Scrambling the phase

destroys the local features global structure but

retains the Fourier energy and net

activation of linear receptive fields

Zeroing the phase

and reflecting destroys the local

features global structure but retains the

symmetry as well Fourier energy and

net linear RF activation

Rotating the face

varies the local features and

Fourier energy, but retains

individuality and emotional

recognition

Inverting the face

retains all the local features and

Fourier energy, but reduces

individuality and emotional

recognition

Facial Inversion Effect

Inverting these full-cue faces shows a large facial inversion effect in both ventral and dorsal regions
