Semantic diversity in children and adult word recognition: The case of Spanish language.

Abstract

Previous evidence has shown an important role for semantic diversity in visual word recognition. These results are theoretically relevant, as they suggest that it is not only the mere repetition of word reading (lexical frequency) but also the semantic context in which words are encountered that affects lexical representation of words. In this study, we assess the role of semantic diversity by applying latent semantic analysis to a Spanish database, deriving word values for semantic diversity. Children and adults performed a lexical decision task to 300 words with different values of this variable while controlling the frequency, age of acquisition, and letter length. The results indicate that adults and children respond faster to words with high semantic diversity than those with lower semantic diversity. These results obtained for the first time in Spanish are consistent with previous findings and support the view that the semantic contexts in which words appear contribute to their lexical representations.
