Year 2 English-educated monolingual children were compared with Welsh-educated bilingual chil- dren, matched for reading instruction, background, locale, and math ability. Welsh children were able to read aloud accurately significantly more of their language (61% of tokens, 1821 types) than were English children (52% tokens, 716 types), allowing them to read aloud beyond their compre- hension levels (168 vs. 116%, respectively). Various observations suggested that Welsh readers were more reliant on an alphabetic decoding strategy: word length determined 70% of reading latency in Welsh but only 22% in English, and Welsh reading errors tended to be nonword mispro- nunciations, whereas English children made more real word substitutions and null attempts. These findings demonstrate that the orthographic transparency of a language can have a profound effect on the rate of acquisition and style of reading adopted by its speakers. Systems that are noisy and inconsistent are harder to sort out than systems that are reliable and categorical. There is now a large body of research demonstrating that greater ambiguity in the mappings between the forms and functions of a particular language causes less successful learning because of a larger degree of competition among the cues in the learning set (Bates & MacWhinney, 1987; MacWhinney, 1987).
