neutral) stimuli, in both visual and olfactory modalities, decreased d’ and thus impeded discrimination between healthy and unhealthy food [ t (15) = −3.16, p < 0.01; disgust d’ = 1.91 (0.78); neutral d’ = 2.11 (0.62)] whereas an opposite, marginally significant trend emerged for the social stimuli: social disgust (vs. neutral) stimuli increased d’ [ t (15) = 1.89, p = 0.08; disgust d’ = 2.11 (0.72); neutral d’ = 1.98 (0.77)] and thus improved food healthiness discrimination.
