Supplementary Figure 11: Ratings of HEX intensity pleasantness and familiarity
From: Altered responses to social chemosignals in autism spectrum disorder
Mean ± SEM Ratings of stimulus intensity pleasantness and familiarity. Verbally reported perception was similar for the clove carrier alone and for the clove carrier with HEX in both TD (n = 16) and ASD (n = 17) groups. A two-way repeated-measures ANOVA on the ratings of stimulus intensity pleasantness and familiarity applied by the participants during the ensuing tasks with factors of Condition (HEX/control), Descriptor (intensity/familiarity/pleasantness) and a categorical independent factor of Group (TD/ASD). This revealed no main effects (all F < 2.6, all p > 0.1), no interaction of Descriptor X Group X Condition (F2,62 = 0.9, p = 0.41), and a trend towards an interaction of Group X Condition (F1,31 = 3.5, p = 0.072). In other words, verbally reported perception was similar for the clove carrier alone and for the clove carrier with HEX in both TD and high-function ASD. All tests were two-tailed, all centers reflect mean, all error bars reflect SEM.
