Table 2.
Viewing times (VTs) and attraction scores = average VTs (in seconds) and attraction ratings (on a 1 to 7 scale) for sexual stimuli in the corresponding age category. Relative VT and attraction scores = difference scores computed as adult–child, so that a positive relative scores indicates that participants gazed longer at adult relative to child stimuli and rated them as more attractive, and vice versa for negative scores. Incest propensity (arousal) = average ratings (on a 1 to 10 scale) of how sexually arousing participants considered incest vignettes; Incest propensity (third person) = average ratings (on a 1 to 10 scale) of how likely they thought that men in the vignettes would encourage continued sexual contact with their daughters; Incest propensity (first person) = average ratings (on a 1 to 10 scale) of how likely participants themselves would encourage continued sexual contact with their own daughter in a similar situation

We report untransformed unstandardized VT and attraction scores here for ease of interpretation, but log-transformed standardized difference scores were used for the analyses. *Comparison significant at p < .05. **Comparison significant at p < .01. Test statistics and effect sizes are reported in Table 3 and Supplemental Table 1
