Phonological priming and regularity effects in reading English and Chinese
Alphabetic writing systems, like English, and logographic writing systems, like Chinese, differ in the nature of the mappings between orthography, phonology, and meaning. This thesis incorporated studies with both behavioural and neuroimaging paradigms to investigate how meaning is computed from orthographic and/or from phonological codes in reading either English or Chinese words. Three sets of homophone priming experiments using the lexical decision task are reported. The first set comprised behavioural experiments in English, where a role for sub-lexical grapheme-phoneme correspondences (GPC) is assumed. More homophone priming was obtained for targets with regular GPCs (e.g. <i>bore-boar)</i> than those with irregular correspondences (e.g. <i>stake-steak)</i> In the context of the dual-route cascaded model (Rastle & Coltheart, 1999), this regularity effect is interpreted as an interaction between the lexical route and a sub-lexical GPC-based route. In a parallel set of experiments with Chinese words and native Chinese speakers/readers, the roles of orthography and phonology were explored by varying the characteristics of phonetic radicals in primes and targets. An influence of the phonetic radical was found
