Timmins, Barnes-Holmes & Cullen (2016) demonstrated that an Implicit Association Test predicted the sexual orientation of gynephilic and androphilic men in terms of their attraction biases towards pictures of nude males and females. Relative bias scores were obtained, with no information on the separate response biases to each target gender. The present study sought to extend this research by assessing both relative and individual implicit biases using the IRAP.and the FAST (Function Acquisition Speed Test). An explicit measure screened for men with androphilic (n=33) or gynephilic (n=25) orientations on the dimensions of sexual attraction, sexual behaviour, sexual fantasies, hetero/gay lifestyle, and self-identification. The IRAP and FAST involved responding TRUE or FALSE to pictures of nude males and females as either attractive or unattractive. Participants were required to respond in a manner consistent with their reported sexual orientation for half of the IRAP and FASTs test blocks and inconsistent for the other half. Response latencies were recorded and analysed. The IRAP revealed a nonorthogonal pattern of biases across the two groups and had an excellent ability to predict sexual orientation with areas under the curves of 0,8313 for the relative bias score and 0,7532 and 0,8557 for the bias scores for the male and female pictures, respectively. Correlations between the IRAP, FAST and explicit measures of sexual orientation were consistently high. The findings support the IRAP as a potentially valuable tool in the study of sexual preferences.
