Extended Data Fig. 1: The perceptual measure of odour-imagery ability positively correlates with self-reported odour and flavor, but not visual, imagery ability.

a–c, The perceptual measure of odour-imagery ability (that is, the interference effect) positively correlated with self-reported odour (a) and flavor (b), but not visual (c), imagery ability. We note that the self-report and perceptual measures of odour-imagery ability did not vary by sex, age, household income, olfactory function or perception, sniff parameters, hunger, or dietary habits (Supplementary Table 4). Scatterplots depict single participants and the 95% CI around the line of best fit. Linear relationships were tested with two-tailed Pearson’s r correlations. p.p., percentage points, referring to the difference in odour detection accuracies (percentages) during matched versus mismatched trials of the odour-imagery condition from the perceptual task (see Fig. 1e,f); VOIQ, Vividness of Olfactory Imagery Questionnaire41; VFIQ, Vividness of Food Imagery Questionnaire8; VVIQ, Vividness of Visual Imagery Questionnaire7; *Pcorrected < 0.05 (3 tests comparing the interference effect to self-reported odour, flavor, or visual-imagery ability).
