suresofsexual interest.Pupillary responseswererecorded during
three of these tasks and in an additional task where no participant
response was required. For adult stimuli, there was a high degree
of intercorrelation between measures, suggesting that tasks may
be measuring the same underlying construct (convergent valid-
ity). In addition to being correlated with one another, mea-
sures also predicted participants’ self-reported sexual inter-
est, demonstrating concurrent validity (i.e., the ability of a task
to predict a more validated, simultaneously recorded, measure).
Latency-based and pupillometric approaches also showed pre-
liminary evidence of concurrent validity in predicting both self-
reported interest in child molestation and viewing pornographic
material containing children. Taken together, the study findings
build on the evidence base for the validity of latency-based
and pupillometric measures of sexual interest.
