“…These measures work on the premise that preferred sexual information is processed differently from non-sexual and nonpreferred information (Geer & Bellard, 1996;Geer & Fuhr, 1976;Geer & Melton, 1997;Janssen, Everaerd, Spiering, & Janssen, 2000;Spiering, Everaerd, & Janssen, 2003); by measuring differences in processing we may obtain an insight into the observer's sexual motivation and interest. Several studies have shown that both explicit, consciously processed sexual stimuli (Geer & Bellard, 1996;Geer, Judice, & Jackson, 1994;Geer & McGlone, 1990) and implicit non-consciously processed sexual stimuli (Spiering et al, 2003;Spiering, Everaerd, Karsdorp, Both, & Brauer, 2006) have an interfering effect on information processing, which requires additional processing time and exerts attentional capture.…”
