Extended Data Fig. 7: Sniff parameters for smelling and imagining the rose and cookie odours.
From: Odour-imagery ability is linked to food craving, intake, and adiposity change in humans

a–d, Normalized sniff traces (mean ± s.e.m.) for smelling the rose (a) and cookie (b) odours and imagining the rose (c) and cookie (d) odours. e–j, Sniff amplitude (e), latency (f), volume (g), duration (h), peak airflow rate (i), and mean airflow rate (j) while smelling and imagining the rose and cookie odours. Differences in the sniff parameters for imagining the cookie minus rose odour were not correlated with any measure of odour-imagery ability (Supplementary Table 4). ANOVAs also revealed no main effects or interactions of modality (smell/imagine), odour (rose/cookie), or the perceptual measure of odour-imagery ability (the interference effect) on any sniff parameter (Supplementary Table 9). Truncated violin plots depict single participants (n = 44) with shading to represent the density of the points around the median line. S, smell; I, imagine; R, rose; C, cookie; a.u., arbitrary units.
