The absence of pleasant and friendly interaction with a woman prior to attack is a typical feature of stranger rape. This might indicate several mechanism.
We hypothesized that genital display of a female preceded by courtship behavior will create lesser penile reaction and lesser brain activation in rapists as opposed to controls, while the ratio will be reversed for the naked female displaying her genitalia proceded by non-courtship-like behaviors. The sample consist of 15 convected male rapists and 15 controls matched for demographic variables.
Participants were exposed to the set of still pictures in several conditions and were simultaneously measured sexual response and brain activity.
