The Effect of Odour Priming on Cortical EEG and Visual ERP Responses

P C Castle et al. Int J Psychophysiol. .

Abstract

Two studies are reported that were designed to examine the way in which subjects, when primed with an olfactory stimulus, make perceptual judgements regarding subsequent congruent/incongruent information. The paradigm used was based on a modified version of a standard ERP semantic priming procedure. Subjects watched a computer screen and made a decision as to whether an image was congruent or incongruent with a priming olfactory stimulus. Results of the two studies showed significant effects in the N400 component of the visual ERP between congruent and incongruent stimuli are reported when a complex malodour accord was used as a prime but not when a complex pleasant odour accord was used as a prime.
