Accessing different types of lexical semantic information: Evidence from priming.

The types of semantic information that are automatically retrieved from the mental lexicon on hearing a word were investigated in 3 semantic priming experiments. The authors probed for activation of information about a word's category membership by using prime-target pairs that were members of a common semantic category (e.g., pig-horse) and 2 types of functional semantic properties: instrument relations (e.g., broom-floor) and script relations (e.g., restaurant-wine). The authors crossed type of semantic relation between prime and target with degree of normative association strength. In a paired and a single-word presentation version of an auditory lexicaldecision priming task, the authors found significant priming for category and functionally related targets, both with and without an additional associative relation. In all cases there was a significant associative boost. However, in a visual version of the single-word lexical-decision paradigm, a different pattern of results was found for each type of semantic relation. Category coordinates primed only when they were normatively associated, instrument relations primed both with and without association, and script relations primed in neither condition. The semantic priming paradigm introduced by Meyer and Schvaneveldt (1971) is one of the most widely used in psychological studies of memory and language. Many studies have demonstrated that participants ' recognition of a target word, such as nurse, is facilitated when it is preceded by a related word like doctor, compared with a neutral or unrelated word
