摘要

When considering print-to-sound word reading, orthography and phonology are obviouslyudinvolved. However, another system, that of semantic memory, might also be involved inudorthography-to-phonology computation. Whether this occurs is debated in the literatureudboth in the interpretation of behavioural results (e.g., Monaghan & Ellis, 2002; Strain et al.,ud1995) and in the implementation of semantic memory within computational models of wordudreading (Coltheart et al., 2001; Plaut et al., 1996). The central aim of this thesis was toudinvestigate whether there is a semantic contribution to orthography-to-phonologyudcomputation in healthy adult word reading. Experiments 1-4 used a semantic priminguddesign in which a picture prime was followed either two trials later (Experiments 1, 3, and 4)udor one trial later (Experiment 2) by a word target, and this investigated priming of variousudword types. Regression investigations explored whether semantic features and imageabilityudwere unique significant predictors of ELexicon single word reading reaction times whileudstatistically controlling for age-of-acquisition. The two ERP experiments (Experiments 5udand 6) investigated the neurocorrelates of imageability and semantic features and whetherudthere are semantic effects early in the time-course of low frequency word reading.udExperiments 1, 2, 4, 5, and 6 and the regression investigations show evidence of a semanticudcontribution to low frequency regular and low frequency exception word reading. There isudalso some suggestion of a semantic contribution to high frequency word readingud(Experiment 2 and Regression analyses). From the results of the three lines of investigation,udit is concluded that semantic information is involved in healthy adult word reading, andudthese results are best accommodated by the connectionist triangle model of word reading.udThese investigations also provide information concerning various word types and factorsudthat contribute to “easy” and “difficult” words, semantic memory models and their accountsudof priming, and the measures, age-of-acquisition, imageability, and semantic features.
