[Effects of the lexical-semantic variables in visual word recognition]

In languages with a deep orthography such as English, a number of studies have shown the effects of lexical and semantic variables on word recognition. In languages with a shallow orthography such as Spanish the regularity of the grapheme - phoneme correspondences may mean that lexical and semantic variables could have less relevant roles. In this study, three variables were tested: frequency, age of acquisition and imageability. These three variables were factorially manipulated in three lexical decision task and three word naming tasks. The results show that in lexical decision both frequency and age of acquisition influence reaction times but imageability was not significant. In the word reading task, only the age of acquisition had a significant effect. The implications of these results for models of reading in Spanish are discussed.
