Abstract
ABSTRACTConventional metaphors such as early bird are interpreted rather fast and efficiently. This is so because they might be stored as lexicalized, non-compositional expressions. In a previous study, employing a maze task, we showed that, after reading metaphors (John is an early bird so he can …), participants took longer and were less accurate in selecting the appropriate word (attend) when it was paired with a literally-related distractor (fly) rather than an unrelated one (cry). This suggests that the literal meaning of conventional metaphors is awakened or made available immediately after their metaphorical interpretation. But does the literal meaning remain available further downstream during sentence comprehension? In two experiments also employing a maze task, we examined whether the awakening effect can be obtained when there is a medium (6 to 8 words) and a large (11 to 13 words) distance between the metaphor and lexical choice. Results indicated that the metaphor awakening effect persists but decreases as word distance increases. An analysis of our data based on a GPT model showed that our maze effects could not be attributed to target predictability. Overall, our results suggest that the literal meaning of a metaphor is accessed and remains available for about three seconds, fading as the sentence unfolds over time. The results support a model of metaphor comprehension that postulates the availability of both literal and metaphoric content in the course of sentence processing.

期刊介绍:
Metaphor and Symbol: A Quarterly Journal is an innovative, multidisciplinary journal dedicated to the study of metaphor and other figurative devices in language (e.g., metonymy, irony) and other expressive forms (e.g., gesture and bodily actions, artworks, music, multimodal media). The journal is interested in original, empirical, and theoretical research that incorporates psychological experimental studies, linguistic and corpus linguistic studies, cross-cultural/linguistic comparisons, computational modeling, philosophical analyzes, and literary/artistic interpretations. A common theme connecting published work in the journal is the examination of the interface of figurative language and expression with cognitive, bodily, and cultural experience; hence, the journal''s international editorial board is composed of scholars and experts in the fields of psychology, linguistics, philosophy, computer science, literature, and media studies.
