The purpose of the current study was to evaluate the temporal stability of a normal heterosexual female response to the Affinity 2.0, a newly standardized viewing time (VT) instrument that purports to measure sexual interest. Participants were 120 female undergraduate and graduate students from a private university (mean age = 21.67 years) who met inclusion criteria of non-pedophilic interest/history, identified as “Exclusively Heterosexual" on the Kinsey Scale, and who took the Affinity 2.0 both at test and at retest (approximately two weeks later). Participants also filled out a questionnaire following the retest composed of demographic questions, a shortened version of the Marlowe-Crowne Desirability Scale-10 [M-C 2(10)], and declared their sexual interest on the Kinsey Scale. Pearson correlation coefficients (PPMCC), Spearman's Rho correlation coefficients, and a Chi-Square Goodness of Fit Test were all utilized to assess the temporal stability of the sample's response to Affinity 2.0. All PPMCC and Spearman's Rho correlations for VT were statistically significant at the p < .01 level; while practical significance for PPMCC could only be considered moderate as best (range of r =.28 - .63), Spearman's Rho correlations (range of r =.41 - .65) were stronger and approached practical significance. The existence of an overall distinct and discernable VT response pattern was apparent as the sample demonstrated identical categorical VT preferences both test and retest. These results were consistent with results from previous VT studies (Quinsey, Rice, Grant & Reid, 1993; Wright & Adams, 1994; Quinsey, Ketsetzis, Earls, & Karamanoukian, 1996). In addition, this VT pattern was found to be stable from test to retest as assessed by a Chi-Square Goodness of Fit Test. An unexpected finding was the presence of elevated VT for adult and juvenile female images. Implications, limitations, and future studies are discussed.
