PurposeIn languages with alphabetical writing systems, the relationship between phonology and orthography is strong. Phonology-to-orthography mappings can be consistent (i.e., one phonological unit corresponds to one orthographic unit) or inconsistent (i.e., one phonological unit corresponds to multiple orthographic units). This study investigates whether the Orthographic Consistency Effect (OCE) emerges at the phonemic level during auditory word recognition, regardless of the opacity of a language’s writing system.MethodsThirty L1-French (opaque language) and 30 L1-Spanish (transparent language) listeners participated in an L1 auditory lexical decision task which included stimuli with either only consistently-spelled phonemes or both consistently-spelled and a number of inconsistently-spelled phonemes. ResultsThe results revealed that listeners were faster at recognizing consistently-spelled words than inconsistently-spelled words. This implies that consistently-spelled words are recognized more easily than inconsistent ones. As for pseudoword processing, there is a numerical trend that might indicate a higher sensibility of French listeners to phoneme-to-grapheme inconsistencies. ConclusionsThese findings have theoretical implications: inconsistent phoneme-to-grapheme mappings, like inconsistencies at the level of the syllable or rhyme, impact auditory word recognition. Moreover, our results suggest that the OCE should occur in all languages with alphabetical writing systems, regardless of their level of orthographic opacity.
The ability to learn new written words is modulated by language orthographic consistency
