RESPONSES:

1. According to the U.S Department of Justice Archives, the new definition of rape is: “The penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim” (Sullivan, Rogers, & Moran, 2017). The Groth typology was developed almost forty years ago. This typology of rape is based on presumed motivations and aims that underline almost all rapes committed by adult males. Groth believed rape to be a “pseudo-sexual act”. He also believed that rape is a symptom of some psychological dysfunction, whether is temporary and transient or chronic and repetitive. Groth divided rape into three major categories. First, anger rape, second, power rape, and sadistic rape. He believed rape is always and foremost an aggressive act. 
The Massachusetts Treatment Center’s Classification Systems of rapists has many similarities to Groth’s typology. The MTC has originally identified four major categories of rapists. One, displaced aggression, two, compensatory, three, sexually aggressive, and four, impulsive rapists. Anger rapists are similar to displaced aggression rapists, sadistic rapists are similar to sexual aggressive rapists. The MTC typology is more extensive and more complex because is based on ongoing research. 

2.The Groth Typology was developed around forty years ago. Groth stated that there is always other motivations, rather than simple sexual arousal, for rapists. He divides rape into three different categories, including anger rape, power rape, and sadistic rape. Anger rape is typically brutal, degrading, and extremely forceful. Anger rapists have some internal anger, usually towards a specific woman, and take it out on their victims. Power rape is when the rapists is establishing dominance and control over their victim. The aggressiveness depends on how submissive the victim is. Victims of power rape are often kidnapped and experience multiple assaults. Sadistic rape involves the rapist experiencing arousal and pleasure of the victim’s torture and abuse. 
Massachusetts Treatment Center’s Classification Systems of rapists is far more complex and researched than Groth’s. It continues to be researched and updated, unlike The Groth Typology. MTC also identifies four types of rapist, rather than three. The types include displaced aggression, compensatory, sexual aggressive, and impulse rapists. Although the two typologies are different, their division of types of rape are similar. Anger rape is similar to displaced aggression, sadistic rape is similar to sexual aggressive rape, and power rape is similar to compensatory rape. The final MTC type of rape is the impulse rape, in which rapists usually have no other history of sexual assault and committed it spontaneously when the opportunity was there. This type has no similarities with any of Groth’s types.
