Abstract
Introduction  Higher psychopathic traits have been consistently associated with poorer olfactory abilities; however, only one study as reported by Sagioglou and Greitemeyer (Appetite 96:299-308, 2016) has explored whether psychopathy is linked to taste perception. Using self-report measures, Sagioglou and Greitemeyer (2016) found higher psychopathic traits were associated with higher liking ratings for bitter stimuli. The aim of the current study was to determine whether direct assessment of taste perception was linked with psychopathic traits.

Methods Seventy-eight participants (41 females) rated four tastants (i.e. bitter, sweet, salty and sour), at four concentrations. For each of the 16 stimuli, participants rated how much they liked, how disgusting and how intense they perceived each tastant.

Results  Contrary to previous findings, higher psychopathic traits were not associated with higher liking ratings for bitter stimuli, but instead associated with higher disgust ratings of bitter stimuli. Moreover, higher psychopathic traits were associated with higher taste intensity ratings, suggesting psychopathy may be associated with increased taste sensitivity.

Conclusions  Higher degrees of psychopathic traits are associated with higher disgust ratings of bitter stimuli.

Implications  The findings suggest that the chemical senses may be another confirmatory method for differentiating those with low and high psychopathic traits.
