Homophobia in men may be, in part, due to reaction formation rooted in unacceptable same-sex attraction. Previous studies have not confirmed a covert same-sex attraction in homophobic men, which is necessary for a reaction formation theory of homophobia. This study sought to reveal possible covert same-sex attraction in homophobic men. In this study, heterosexual and homosexual male erotic images were presented in a passive S1/S2 stimulus prediction design to 48 self-identified heterosexual participants, grouped by homophobia. Three event-related potential responses related to valenced emotional processing were examined: the medial frontal negativity (MFN), the late positive potential (LPP), and the positive frontal slow wave (FSW). While homophobic men have a larger FSW in response to erotics across the board, F(1,46) = 3.88, p = .055, no significant interactions between homophobia and image content were found. As such, homophobic men may have more interest in erotic images in general, but this study does not demonstrate that homophobic men find homosexual erotics appetitive.
