Distributions of estimates the numerousness of the circles, made by groups of subjects following either 95 ms or 2 s exposures had realistic average values, and were comparable between groups, indicating that gists of the principal geometrical features of the stimuli were captured and consolidated into long-term memory on the basis of a single fixation. Implications of this finding for the controversy on the nature of the coding of images and for the minimalist vision hypothesis are discussed. date: 2001 date_type: published refereed: FALSE referencetext: Anstis,S.M.
