Kurt Freund was a Czech-Canadian physician and sexologist best known for developing the penile plethysmograph, research studies in pedophilia, and for the "courtship disorder" hypothesis as a taxonomy of certain paraphilias. After unsuccessful attempts to change men's sexual orientation, he advocated against conversion therapy and in favor of the decriminalization of homosexuality.
Penile plethysmography (PPG) or phallometry is a measurement of blood flow to the penis, typically used as a proxy for measurement of sexual arousal. The most commonly reported methods of conducting penile plethysmography involves the measurement of the circumference of the penis with a mercury-in-rubber or electromechanical strain gauge, or the volume of the penis with an airtight cylinder and inflatable cuff at the base of the penis. Corpora cavernosa nerve penile plethysmographs measure changes in response to inter-operative electric stimulation during surgery. The volumetric procedure was invented by Kurt Freund and is considered to be particularly sensitive at low arousal levels. The easier to use circumferential measures are more widely used, however, and more common in studies using erotic film stimuli. A corresponding device in women is the vaginal photoplethysmograph.
Chemical castration is castration via anaphrodisiac drugs, whether to reduce libido and sexual activity, to treat cancer, or otherwise. Unlike surgical castration, where the gonads are removed through an incision in the body, chemical castration does not remove organs and is not a form of sterilization.
Forensic psychology is the practice of psychology applied to the law. Forensic psychology is the application of scientific knowledge and methods to help answer legal questions arising in criminal, civil, contractual, or other judicial proceedings. Forensic psychology includes research on various psychology-law topics, such as jury selection, reducing systemic racism in criminal law, eyewitness testimony, evaluating competency to stand trial, or assessing military veterans for service-connected disability compensation. The American Psychological Association's Specialty Guidelines for Forensic Psychologists reference several psychology subdisciplines, such as social, clinical, experimental, counseling, and neuropsychology.
Criminal psychology, also referred to as criminological psychology, is the study of the views, thoughts, intentions, actions and reactions of criminals and suspects. It is a subfield of criminology and applied psychology.
A behavior modification facility is a residential educational and treatment institution enrolling adolescents who are perceived as displaying antisocial behavior, in an attempt to alter their conduct.
A sex offender is a person who has committed a sex crime. What constitutes a sex crime differs by culture and legal jurisdiction. The majority of convicted sex offenders have convictions for crimes of a sexual nature; however, some sex offenders have simply violated a law contained in a sexual category. Some of the serious crimes which usually result in a mandatory sex-offender classification are sexual assault, statutory rape, bestiality, child sexual abuse, incest, rape, and sexual imposition.
Pedophilia is a psychiatric disorder in which an adult or older adolescent experiences a primary or exclusive sexual attraction to prepubescent children. Although girls typically begin the process of puberty at age 10 or 11, and boys at age 11 or 12, psychiatric diagnostic criteria for pedophilia extend the cut-off point for prepubescence to age 13. People with the disorder are often referred to as pedophiles.
Psychopathy, or psychopathic personality, is a personality construct characterized by impaired empathy and remorse, and bold, disinhibited and egocentric traits, masked by superficial charm and the outward appearance of apparent normalcy.
Sibling abuse includes the physical, psychological, or sexual abuse of one sibling by another. More often than not, the younger sibling is abused by the older sibling. Sibling abuse is the most common of family violence in the US, but the least reported. As opposed to sibling rivalry, sibling abuse is characterized by the one-sided treatment of one sibling to another.
The Psychopathy Checklist or Hare Psychopathy Checklist-Revised, now the Psychopathy Checklist—revised (PCL-R), is a psychological assessment tool that is commonly used to assess the presence and extent of psychopathy in individuals—most often those institutionalized in the criminal justice system—and to differentiate those high in this trait from those with antisocial personality disorder, a related diagnosable disorder. It is a 20-item inventory of perceived personality traits and recorded behaviors, intended to be completed on the basis of a semi-structured interview along with a review of "collateral information" such as official records. The psychopath tends to display a constellation or combination of high narcissistic, borderline, and antisocial personality disorder traits, which includes superficial charm, charisma/attractiveness, sexual seductiveness and promiscuity, affective instability, suicidality, lack of empathy, feelings of emptiness, self-harm, and splitting. In addition, sadistic and paranoid traits are usually also present.
Sexual violence refers to a range of completed or attempted sexual acts in which the affected party does not or is unable to consent. Theories on the causes of sexual violence are numerous and have come out of many different disciplines, such as women's studies, public health, and criminal justice. Proposed causes include military conquest, socioeconomics, anger, power, sadism, traits, ethical standards, laws, and evolutionary pressures. Most of the research on the causes of sexual violence has focused on male offenders.
Child sexual abuse (CSA), also called child molestation, is a form of child abuse in which an adult or older adolescent uses a child for sexual stimulation. Forms of child sexual abuse include engaging in sexual activities with a child, indecent exposure, child grooming, and child sexual exploitation, such as using a child to produce child pornography.
A sex offender registry is a system in various countries designed to allow government authorities to keep track of the activities of sex offenders, including those who have completed their criminal sentences.
A range of research has been conducted examining the link between viewing child pornography and perpetration of child sexual abuse, and much disagreement persists regarding whether a causal connection has been established. Perspectives fall into one of three positions:
David Lisak is an American clinical psychologist. He received his PhD from Duke University, and is a retired associate professor of psychology at the University of Massachusetts Boston. Lisak's research focuses on "the causes and consequences of interpersonal violence...motives and behaviors of rapists and murderers, the impact of childhood abuse on adult men, and relationship between child abuse and later violence".
Paradox psychology is a counter-intuitive approach that is primarily geared toward addressing treatment resistance. The method of paradoxical interventions (pdxi) is more focused, rapid, and effective than Motivational Interviewing. In addressing resistance, the method seeks to influence the clients' underlying attitude and perception by providing laser beam attention on strengthening the attachment-alliance. This is counter-intuitive to traditional methods since change is usually directed toward various aspects of behavior, emotions, and thinking. As it turns out, the better therapy is able to strengthen the alliance, the more these aspects of behavior will change.
Devon Leigh Logan Polaschek is a New Zealand professor of psychology and of Crime Science at the University of Waikato in New Zealand who studies high-risk violent offenders in prisons and on parole.
Karen Franklin is an American forensic psychologist. For her doctoral dissertation, she conducted research on anti-gay violence. She has also published commentaries about sex crimes, primarily expressing her opposition to the use of the hebephilia and other diagnoses in sexually violent predator regulations. She received the 2012 Distinguished Scientific Achievement Award in Psychology and the Monette-Horwitz Trust Award in 2001.
Sex offender registration and notification (SORN) laws in the United States are widely accepted, with supporters believing that disclosing the location of sex offenders residence improves the public's ability to guard themselves and their children from sexual victimization. Despite this wide public acceptance, empirical observations do not uniformly support this belief.
