This study explored the effect of language priming on perceived odour intensity. This was investigated by measuring changes in EEG alpha wave amplitude, and through a perceived odour intensity self-report scale among 32 participants. The experiment used a 2x2 between-subjects factorial design with a within-subjects component. Four conditions investigated differences between 2 odour stimuli containing drops of rosemary essential oil that were of the same intensity in the presence and absence of a language prime, and odours of varying intensities in the presence and absence of a language prime. A mixed factorial ANOVA found no significant effects for differences across conditions for varying intensities or language prime on perceived odour intensity or EEG amplitude.
