“…There is growing evidence that all types of incest that start early in the victims' lives tend to result in early hyper-eroticization of the victims that persists into adulthood (e.g., Beard et al, 2013;Stroebel et al, 2012;Stroebel, O'Keefe, Griffee et al, 2013;Yates, 1982), and the mechanism behind this effect appears to be a type of early learning directly related to sexual functioning called sexual imprinting ; for a review of animal studies on sexual imprinting see Irwin & Price, 1999) working in concert with Pavlovian conditioning and operant conditioning Bickham et al, 2007). Furthermore, sexual imprinting working in concert with Pavlovian conditioning and operant conditioning is the mechanism that explains the powerful tendency of same-sex sibling incest or non-incestuous early experiences with same-sex partners to produce permanent adult same-sex or bisexual orientations in the victims Bickham et al, 2007;Hoffman, 2012;Pfaus et al, 2012;Robinett, 2012;Stroebel, O'Keefe, Griffee et al, 2013).…”
