Snowden, Wichter, and Gray
(2008) demonstrated that an Implicit Association Test and a Priming Task both
predicted the sexual orientation of gynephilic and androphilic men in terms of
their attraction biases towards pictures of nude males and females. For both
measures, 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 Implicit Relational Assessment Procedure (IRAP). An explicit measure
screened for men with androphilic (n = 16) or gynephilic
(n = 16) orientations on the dimensions of "sexual
attraction," "sexual behavior," "sexual fantasies,"
"hetero/gay lifestyle," and "self identification." The IRAP
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's test blocks and inconsistent for the other
half. Response latencies were recorded and analyzed.
The IRAP revealed a
non-orthogonal pattern of biases across the two groups and had an excellent
ability to predict sexual orientation with areas under the curves of 1.0 for
the relative bias score and .94 and .95 for the bias scores for the male and
female pictures, respectively. Correlations between the IRAP 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.
