1. Passivity during sexual assault is a common response of both child and adult victims.
Studies suggest that anywhere from 1/3 of adult rape survivors (Heidt, Marx, & Forsyth, 2004) to 1/2 of child sexual abuse survivors (Heidt, Marx, & Forsyth, 2004) display a passive, even frozen, response during the assault. Naturally, people do wonder why and how this passive response occurs, but it is important to recognize that, separate from questions of motivation and mechanism, we know from empirical scientific research on sexual victimization that such a passive response is quite common (Marx, Forsyth, & Lexington, 2008; Rizvi, Kaysen, Gutner, Griffin & Resick, 2008). There are research studies attempting to answer the 'why' and 'how' questions regarding victim passivity. It appears that there are a number of factors (such as power disparity) and pathways that are associated with a passive response ranging from a conscious decision based on the assessment that it is a wise course of action given the dangers of resisting, to involuntary physiological responses of paralysis or freezing. In the scientific literature on sexual assault this constellation of victim passive/freeze responses is sometimes called 'rape induced paralysis' and increasingly often called 'tonic immobility' although there is also a more technical use of that term (Marx, Forsyth, & Lexington, 2008).
