Abstract
The purpose of this study was to investigate the nature of information processing for a briefly presented visual array of Japanese Kana letters. Two experiments were conducted, with the same five subjects, to examine the effects of retinal locus, relative position within an array and lateral masking on partial report performance. Types of errors were also analyzed in order to examine whether these effects were related to identification, localization, or both. Proportions of correct responses, location errors, and item errors as a function of stimulus position were found to suggest that partial report performance does not depend only on the identification processes, but also on the localization processes. These findings were discussed on the basis of dual buffer model proposed by Mewhort, Campbell, Marchetti, and Campbell (1981).
