A study was conducted to investigate the effect of odor primes on the Stroop phenomenon. If an appropriate prime gives a particular cue to a color-word stimulus, the reaction time is faster and if it's inappropriate, the reaction is slower. Odor primes (pleasant vs. unpleasant) should effect performance on the Stroop task for both words that are congruent to the particular odor, and incongruent to an odor. 40 undergraduate students at a Canadian university were randomly assigned to one of four conditions, and were administered a modified Stroop task. Participants in the first two conditions were tested in the presence of a pleasant scent and either tested with pleasant or unpleasant words. Participants in the last two conditions were tested in the presence of an unpleasant scent and were either tested with pleasant or unpleasant words. Performance was measured by the time it took to complete the Stroop task. A 2 X 2 between subjects ANOVA was performed and insignificant main effects and interaction effects were found. Implications for future studies and research are addressed.
