III. RESULTS 24
3.1 No significant differences in intensity between the odors were observed in the behavioral test 24
3.2 A color with high association and a color with low association with a particular odor exists 26
3.3 No significant differences were observed in the odor perception questionnaire task among color conditions 29
3.4 Color association alter odor quality profile 31
3.5 No significant differences in intensity between the odors were observed in the EEG recording test 38
3.6 Significant amplitude changes were observed in both negative potential (NP) and positive potentials (PP) 40
3.7 Changed NP and PP patterns across the conditions are related to the behavior test. 57
