A Conncetionist Model of Form-related Priming Effects
In contrast to the results of many previous studies, Colombo (1986) has demonstrated that form related priming is sometimes inhibitory. Colombo proposed that inhibition reflects the suppression of lexical items orthographically related to the prime. We suggest, however, that form-related inhibition arises as a result of competition between discrepant prime-target phonemes. During the phonological encoding of the target word, active phonemes from the prime might be mistakenly selected, causing a delay in responding. We present a connectionist model that implements this account, and simulates tiie empirical data. The model is supported by the results of an experiment that distinguishes between the lexical suppression and phonological competition view

Anatomising Lexical Decision In Phrasal Contexts: When Does Truck Not Prime Car
Context effects on lexical decisions were anatomised bymanipulating lexical relatedness in syntactic andasyntactic sequences. In a Syntactic condition, relatedor unrelated word-pairs were embedded in simplesequences (e.g., a truck or a CAR/FLOOR). In aScrambled condition, two inapposite function words weresubstituted between the related and unrelated nouns(e.g., the truck that before CAR/FLOOR). The phraseswere presented serially and subjects made lexicaldecisions to their terminal elements. Substantialrelatedness effects were found only in syntacticsequences, whether presentation rate was slow or whetherit exceeded the rate of normal reading. The syntacticrelatedness effect was shown to consist, in equalproportions, of facilitation of related words andinhibition of unrelated words. These results argueagainst a role for intralexical priming in on-linereading. They point up the roles of syntacticconnectedness and of the current interpretation even invery rudimentary contexts
