Metaphor,Simile, Analogy and the Brain

Abstract

Fox argues that the poetic function of language fulfils the human need to symbolise. Metaphor, simile and analogy provide examples of the ways in which symbolic language can be used creatively. The neural representations of these processes therefore provide a means to determine the neurological basis of creative language. Neuro-imaging has demonstrated that while metaphor, simile and analogy activate some areas of the brain in common, they also each activate different areas. This suggests that creative language has had sufficient evolutionary importance to be processed within more than one neural system. Additionally, the neuro-imaging data suggest that symbolic language activates areas beyond the language centres and therefore is encoded using sensorimotor representations. Here we will discuss the neural representations of metaphor, simile and analogy, and will reflect on the neural systems which have evolved to support symbolic language and how this understanding might be used to help develop skill in creative language.
