You might look into the work of Seamon, Brody, and Marsh from about
1984. There are two or three relevant papers that came out in
Jour Exp Psych: Learning, Mem, & Cog. or in JEP: General. One of
their studies examined exposure time on affective discriminations
and recognition. Affective discimination effects for 8-sided polygons
occurred after exposures as low a 1 ms. If I'm not mistaken, effects
on recognition memory did not emerge until the exposure duration
reached a minimum of 8 ms. Many studies have found affective
discrimination effects at exposures of 1 ms. Hope this helps.
