摘要
Objective: The right visual field superiority (RVFS) for words may be explained by the cerebral lateralization for language, the scanning habits in relation to script direction, and spatial attention. The present study explored the influence of spatial attention on the RVFS in relation to scanning habits in school-age children. Methods: French second- and fourth-graders identified briefly presented French parafoveal words. Tunisian second- and fourth-graders identified Arabic words, and Tunisian fourth-graders identified French words. The distribution of spatial attention was evaluated by using a distracter in the visual field opposite the word. Results: The results of the correct identification score showed that reading direction had only a partial effect on the identification of parafoveal words and the distribution of attention, with a clear RVFS and a larger effect of the distracter in the left visual field in French children reading French words, and an absence of asymmetry when Tunisian children read Arabic words. Fourth-grade Tunisian children also showed an RVFS when reading French words without an asymmetric distribution of attention, suggesting that their native language may have partially influenced reading strategies in the newly learned language. However, the mode of letter processing, evaluated by a qualitative error score, was only influenced by reading direction, with more sequential processing in the visual field where reading %26quot;begins.%26quot; Conclusion: The distribution of attention when reading parafoveal words is better explained by the interaction between left hemisphere activation and strategies related to reading direction. We discuss these results in light of an attentional theory that dissociates selection and preparation.
