Investigation of the Neural Mechanism of Feature Emergence in Metaphor Understanding by Near Infrared Spectroscopy (NIRS)

摘要

Introduction: In this paper, the neural activation of feature emergence, which occurs within the understanding process of metaphors represented in the form of "A is like B", is measured using near infrared spectroscopy (NIRS). Many studies have pointed out that the left hemisphere (LH) is involved in metaphor comprehension (Rapp et al. 2004, Shibata et al. 2007 et al. ), but it is a matter of debate as to whether the right hemisphere (RH) is also involved. In this paper, it is examined whether the RH contributes the process of emergent feature.
