Sexual Arousal
Sexual arousal was induced by having participants watch a 5-min erotic movie clip. The erotic movie clip showed a heterosexual couple engaging in oral sex and subsequently in (unprotected) vaginal penetration. The clips were pilot-tested for being sufficiently sexually arousing and have been used in other studies (e.g., Grauvogl et al., To ensure participants in the experimental condition stayed aroused after watching the video clip, they heard the audio from an erotic movie via a headphone set while they performed the working memory task. In the control condition, participants heard the audio from the BBC Earth documentary. The n-back working memory task, which was used for measuring working memory capacity, is a demanding cognitive task and therefore will act as a distractor and lead to a decrease in sexual arousal (Geer & Fuhr,
