Abstract

In a series of experiments in which participants had to classify stimuli as letters versus shapes we found a differentiation between holistic non-letter processing and analytic letter processing in adults. In a recent study we investigated whether this distinction is also present in literates. We found that the differentiation is absent in illiterates; they uniformly showed analytic perception for both letters and non-letters.
