Children's sensitivity to rime unit frequency when spelling words and nonwords

This paper presents two experiments investigating 8–9 year old children's sensitivity to rime level sound-spelling correspondence units when spelling words and nonwords. In Experiment 1, children spelled more words correctly if they contained a common rime unit rather than a unique or irregular unit. In Experiment 2, children spelled more words and nonwords correctly if they had many rime unit neighbours; words and nonwords with average or few rime unit neighbours were spelled less well. These findings show that children's spelling can not be described simply according to one-to-one phoneme-grapheme mapping. Instead, children are sensitive to lexical factors such as rime unit sound-spelling correspondence. The findings are interpreted within the framework of a connectionist model of spelling development.
