Correct stress assignment is a requirement for fluent reading in alphabetic languages. This study focuses on two nonlexical mechanisms at the core of stress assignment. In particular, the use of a default stress pattern (e.g., penultimate stress) and the Spanish stress mark. In Experiment 1, participants read aloud words and pseudowords with different stress types (on the antepenultimate or the penultimate syllable), and with or without a stress mark. Results showed longer reaction times (RTs) for words and pseudowords with antepenultimate stress. However, as words with antepenultimate stress always have a stress mark, it could be argued that stress type differences could be due to the presence of the stress mark. In Experiment 2, using a priming procedure participants read aloud words and pseudowords in pure versus mixed stress blocks. Again, words and pseudowords with antepenultimate stress were read slower (longer RTs), suggesting that previous differences were due to stress mark rather than stress type. These results indicate that processing stress marks is cognitively demanding when reading in Spanish. [ABSTRACT FROM AUTHOR]

The relationship between written words and their pronunciation varies considerably among different orthographic systems, and these variations have repercussions on learning to read. Children whose languages have deep orthographies must learn to pronounce larger units, such as rhymes, morphemes, or whole words, to achieve the correct pronunciation of some words. However, children whose languages have transparent orthographies need only learn to pronounce graphemes to be able to read any word. In this study, the reading evolution of Spanish-speaking children was investigated for the purpose of discovering when and for what types of stimuli lexical information is used in Spanish. Five- to 10- year-old children were presented with lists of stimuli in which lexicality, frequency, and length were manipulated. The results in terms of reading accuracy and speed showed that the influence of stimulus length is great in the early grades and later diminishes, and just the opposite is the case for lexicality and frequency. These data suggest that reading acquisition in Spanish constitutes a continuum that ranges from phonological recoding to the use of lexical strategies, and that this transition is made at a very early stage, at least for the most frequent words.
