Abstract

The current research explored continuous behavioral processes by recording participants’ hand movements towards a response option using Mousetracker software. Across three studies, we tested the idea that sexual interest-related decisions can be indexed using automatic movements. Using a UK sample of self-identified same and opposite-gender attracted men (N = 43), Study 1 showed that the process of approaching the response button is faster, more direct, and less curved when participants respond from their own (vs. a non-preferred) perspective. Study 2 supported these findings using a German sample of self-identified same- and opposite-gender attracted men (N = 66). Using a teleiophilic sample of 100 self-identified opposite-gender attracted men (n = 51) and women (n = 49), Study 3 examined age-specific sexual interests (i.e., responding to stimuli from a pedophilic and a teleiophilic perspective). As expected, in the teleiophilic block, participants’ responses were faster, more direct, and less curved than in the pedophilic block. Collectively, the results suggest that mousetracking shows promise as a measure of sexual interest (across the dimension of both gender and age), providing grounds for future research.
