"I look in your eyes, honey": internal face features induce spatial frequency preference for human face processing.

Numerous psychophysical experiments found that humans preferably rely on a narrow band of spatial frequencies for recognition of face identity. A recently conducted theoretical study by the author suggests that this frequency preference reflects an adaptation of the brain's face processing mach...
