Objective: Current study aims to investigate the cerebral lateralisation phenomena specific to the literal versus figurative language processing. Methods: To further test the contribution of dorsolateral prefrontal cortex in both right and the left hemisphere during the processing of figurative meaning and literal meaning, we used an interference approach by means of repetitive transcranial magnetic stimulation (rTMS). Eighteen young healthy participants (mean age: 20.72) underwent rTMS pulses at 1 Hz frequency, 110% of motor threshold intensity for 15 minutes (900 pulses) in two sessions at one-week interval. The target DLPC positions (right and left) of each participant were determined with Modified Beam Method (Beam et.al., 2009). A semantic judgement task comprised of idioms (for figurative meaning) and literal sentences (for literal meaning) was performed on a PC. Participants have been asked to judge the relatedness of an idiom (or a literal expression) and a following target word by pressing a button on a response key. The target word was either figuratively related or literally related to the idiom. Reaction times and accuracy scores data from semantic judgement task were analysed using linear mixed effects models. Results: Results revealed that bilateral DLPC plays a role in figurative language processing however left DLPC has been observed more critical during figurative meaning processing than that of right DLPC. Unlike figurative meaning processing, no such hemispheric or stimulation effects were observed for literal meaning processing. Besides the left DLPC functions are critical in the selection but not supression of one of two competing interpretations that are activated in terms of literal and figurative meaning of an idiom. Conclusion: Left DLPC functions are more critical in figurative meaning processing than the right DLPC. General DLPC functions are not critical for literal meaning processing. The selection and inhibiton components are localised in different cortical areas. [ABSTRACT FROM AUTHOR] |
