Interhemispheric interactions in visual word recognition: the role of multiple meanings
1Department of Psychology, Chonnam National University, Gwangju, Republic of Korea.
Introduction:
The current study investigated the influence of the number of meanings on visual word recognition, with a particular focus on hemispheric dynamics.
Methods:
By reanalyzing parafoveal Korean lexical decision data, we examined how words with a high versus low number of meanings affect right visual field advantage (RVFA) and bilateral redundancy gain (BRG).
Results:
The words with a greater number of meanings exhibited a stronger RVFA and reduced BRG compared to words with fewer meanings.
Discussion:
The findings suggest that the facilitatory effects associated with multiple meanings are more pronounced in the left hemisphere (LH) than in the right hemisphere (RH). Furthermore, the increased lateralization of processing within the LH appears to diminish the need for interhemispheric interactions, leading to decreased coordination between the hemispheres. These results imply that the number of meanings in words shapes interhemispheric dynamics during visual word recognition. The implications of these findings are discussed in relation to theoretical models of visual word recognition and hemispheric differences in language processing.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
