Abstract
The role of parts versus that of wholes in a visual perception has been debated for a century as two opposite approaches namely an analytic and holistic In two psychophysical experiments we investigated whether the stimulus completeness or distinctiveness is essential for identification of the partially presented patterns under brief presentation conditions For this purpose a special class of stimuli was constructed in such a way that the patterns could be divided into informative and redundant parts The first experiment clearly demonstrated the importance of the redundant part for effective pattern identification for the majority of subjects The second experiment revealed the direct dependence of identification accuracy of the patterns on their completeness 2 3 4 5 or 6 elements Familiarisation of subjects with the test stimuli influenced the strength of this dependence
