Abstract Background: Studies on food cue reactivity have documented that altered responses to high-calorie food are associated with bulimic symptomatology, however, alterations in sexual motivations and behaviors are also associated clinical features for this population, which justify their inclusion as a research target. Here, we study responses to erotic cues – alongside neutral and aversive cues – to gain an understanding of specificity to food vs. a generalized sensitivity to primary reinforcers. Methods: We recorded peripheral psychophysiological indices –the startle reflex, zygomaticus, and corrugator responses– and self-reported emotional responses (valence, arousal, and dominance) in 75 women that were presented with the Spanish version of the Bulimia Test-Revised (BULIT-R). Multiple regression analysis tested whether BULIT-R symptoms were predicted by self-reported and psychophysiological responses to food vs. neutral and erotic vs. neutral images. Results: The results showed that individuals with higher bulimic symptoms were characterized by potentiated eye blink startle response during binge food (vs. neutral images) and more positive valence ratings during erotic (vs. neutral) cues. Conclusions: The results highlight the negative emotional reactivity of individuals with elevated bulimic symptoms toward food cues, which could be related to the risk of progression to full bulimia nervosa and thereby addressed in prevention efforts. Results also point to the potential role of reactivity to erotic content, at least on a subjective level. Theoretical models of eating disorders should widen their conceptual scope to consider reactivity to a broader spectrum of primary reinforcers, which would have implications for cue exposure-based treatments.
