This study investigates the effects of on speakers’ ability Accuracy to detect rhymes and count in response to written stimuli in All languages: accuracy better in French, English, and Italian. It examines variation across differing the same category than in all other categories orthographic conditions within a single language, as well as variation Both English and French: across the differing orthographic depths of the three languages studied. accuracy better for systematic category than for silent category Average accuracy in every category was worse in French than in English and Italian 2.
