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…

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…

Landau, Ayelet N.; Bentin, Shlomo – Journal of Experimental Psychology: Human Perception and Performance, 2008
When 2 different visual targets presented among different distracters in a rapid serial visual presentation (RSVP) are separated by 400 ms or less, detection and identification of the 2nd targets are reduced relative to longer time intervals. This phenomenon, termed the "attentional blink" (AB), is attributed to the temporary engagement…
