there is an apparent relationship between certain personality traits and sensory capacities.…[S]ensory capacity may provide a filter through which we perceive the world, and that this filter may influence the picture we receive of the world….We found no coherence between personality traits and gustatory modality (mainly related to eating) but significant coherence between personality traits and olfactory, trigeminal sensory and electrical cutaneous modality; systems usually thought to be related to detection of social cues and awareness of danger.
If behavior is the output of a reaction to a stimulus, part of the behavior (and therefore personality) will be related to how each stimulus is perceived. It is interesting to find this at such a basic level (as opposed to say, the global stimulation experienced by the extravert versus the introvert).
