Flevaris, Anastasia V.; Bentin, Shlomo; Robertson, Lynn C. – Journal of Experimental Psychology: Human Perception and Performance, 2011
Ample evidence suggests that global perception may involve low spatial frequency (LSF) processing and that local perception may involve high spatial frequency (HSF) processing (Shulman, Sullivan, Gish, & Sakoda, 1986; Shulman & Wilson, 1987; Robertson, 1996). It is debated whether SF selection is a low-level mechanism associating global…

Gao, Zaifeng; Bentin, Shlomo – Journal of Experimental Psychology: Human Perception and Performance, 2011
Face perception studies investigated how spatial frequencies (SF) are extracted from retinal display while forming a perceptual representation, or their selective use during task-imposed categorization. Here we focused on the order of encoding low-spatial frequencies (LSF) and high-spatial frequencies (HSF) from perceptual representations into…

Harel, Assaf; Bentin, Shlomo – Journal of Experimental Psychology: Human Perception and Performance, 2009
The type of visual information needed for categorizing faces and nonface objects was investigated by manipulating spatial frequency scales available in the image during a category verification task addressing basic and subordinate levels. Spatial filtering had opposite effects on faces and airplanes that were modulated by categorization level. The…
