Concurrent predictors of spelling accuracy in secondary education in a semi-consistent orthography

Abstract

Abstract Spelling is a complex skill that requires mobilizing various levels of linguistic and orthographic representation. While there is substantial evidence of the impact of phonological skills in its development, less is known about the explanatory value of non-phonological (e.g., morphological, orthographic) strategies in conventional spelling scores. This study assessed the unique impact of non-phonological spelling strategies after accounting for a large set of linguistic and cognitive predictors, as well as contextual variables (e.g., SES) in a language with a semi-consistent orthography: Catalan. Participants were 328 eighth-grade students from low-income households. Results showed that non-phonological spelling skills explained a substantial proportion of the variance in conventional spelling, over and above the rest of predictor variables, including phonographic skills, with the final model explaining more than 80% of the variance. Theoretical and educational implications are discussed.
