Processing Conventional Conceptual Metaphors in Persian: A Corpus-Based Psycholinguistic Study

Abstract

Research on the psycholinguistic processing of conceptual metaphors has produced contrasting results in recent years. There have also been criticisms that in experimental studies of metaphor processing, linguistic stimuli are mostly intuition-based and not designed objectively based on the original language use data. To address these issues, we studied the processing of conventional metaphoric expressions in Persian language using corpus data. A reading time experiment was designed to test whether conventional metaphoric expressions activated conceptual metaphors. A corpus of 50 million word tokens was used to study the conventional patterns of metaphoric expressions usages and construct experimental items. Fifty five Persian speakers read a set of scenarios containing non-conventional metaphor, conventional metaphor and non-metaphor expressions on computer and the reading times of the following novel target sentence in each condition were recorded by DMDX stimulus presenter program. Comparing mean reading times using one-way ANOVA revealed that reading target sentence after conventional metaphor scenarios had been significantly faster than non-metaphor scenarios, but slower than non-conventional scenarios. The results show that conventionality has a weakening effect on the strength of metaphoric expressions to activate conceptual metaphors.
