Phonological precision for word recognition in skilled readers
This study investigated individual differences in the neighbourhood density effect observed during the processing of written words. A masked priming experiment measured form priming for word and pseudoword targets from dense and sparse neighbourhoods in 84 university students. In addition, individual difference measures of language and cognitive processes were collected, and a principal component analysis was used to group these data into factors. We observed facilitatory form priming for words with a sparse neighbourhood and inhibitory form priming for words with a dense neighbourhood. A factor relating to phonological precision was positively related to priming effects for word targets with sparse neighbourhoods, but negatively related to priming effects for word targets with dense neighbourhoods. These results suggest that the component of phonological precision is linked to the inhibitory effects of lexical competition for word recognition. The implications for theories of reading skills, such as the Lexical Quality Hypothesis, are discussed.
