A Review On Abnormal Amygdala

The amygdala of psychopaths have has been found to be hypoactive during fear conditioning (Birbaumer et al., 2005), moral decision-making (Glenn, Raine, & Schug, 2009), and social cooperation (Rilling et al., 2007). As expected, studies have also found the amygdala to be hypoactive in response to fearful faces or other affect-related activity (e.g. Carré et al., 2013; Kiehl et al., 2001). Nevertheless, Müller et al. (2003) found that psychopaths had increased activation in the amygdala (in addition to increased prefrontal activation) when viewing negative content (e.g. pictures of threatening animals, wounded people) which they interpreted as reflecting abnormal prefrontal – amygdala communication.” (Umbach et al., 2015,

Since it is close structurally to the hippocampus, the amygdala is involved in controlling memory consolidation, especially emotional memories; when a memory is emotionally charged, it has a better retention rate than one that is not. The hippocampus is generally seen as having an essential role in the creation of new memories about past experiences; it's even responsible for memories that can be verbalized also known as declarative memory. Damage to it result in difficulties in forming new memories and being able to access new memories formed before the

Studying parts of the brain that are involved in dealing with fear and stress also helps researchers understand possible causes of PTSD to begin formulating a plan to treat PTSD. The amygdala is known for its role in emotion, learning, and memory. The amygdala appears active in learning to fear an event as well as in the early stages of fear extinction. In storing extinction memories and dampening an existing fear the prefrontal cortex, which is involved in problem solving, decision making, and judgement, is seemingly

With the Pandora’s Box opened, we may find ourselves forced to rediscover morality due to our natural tendencies. This does not mean accepting adult-child relationships. Figure 3 indicates if we are serious about protecting children, then that ultimately requires some level of understanding, which is a problem for most because that is dangerously close to compassion. On the contrary, the risk they pose is the very reason why we need to support pedophiles who do not want to become sex offenders. We all want the same thing. We do not want them to offend nor their potential victims to offend. In 2008, Michael Seto, a forensic psychologist, published a book stating that the onset of pedophilia is right around the stages of puberty, as with any other sexual orientation. I believe we can prevent a greater number of victims if we put more energy into early detection and providing support before the first offense occurs, rather than solely relying on punishment after the fact. We need to be thinking about the children that pedophiles once were and catch them at their vulnerable stages, which are during puberty. There we can find a sense of compassion and support to want to help. In 2014, Margo Kaplan, an associate professor at Rutgers School of Law, wrote an op-ed in New York Times stating that pedophilia is neurologically rooted, supporting Cantor’s research.

Sex offenders tend to blend in to society virtually unnoticed until they offend or reoffend (Polizzi, MacKenzie, & Hickman, 1999). Currently, there is a large group of mental health professionals representing a variety of disciplines, including psychology, psychiatry clinical social work, counseling, and medicine, that continue to believe in the potential efficacy of treating sex offenders. Over the past decade, the sex offender treatment field has grown rapidly and the treatment of juvenile sex offenders is on the rise (Parks & Bard, 2006). The rationale for treating juvenile offenders is based on research which indicates that inappropriate sexual behavior patterns develop early and a failure to intervene and change behavior early often means that the offender will continue to escalate his/her inappropriate behavior, which could present an even greater danger to society (Ayland & West, 2006). Vivian-Bryne, (2004) suggests that professionals who treat adult sex offenders report that offenders who are incarcerated will eventually return to the community and therefore, therapeutic measures should be taken to reduce the likelihood that they will reoffend even if those measures have not conclusively been identified as effective. Sexual offenders may find therapy valuable because it can allow them to retrace their upbringing to help them identify and understand the roots of their

Most people consider pedophiles to be anyone who has committed a sex offense against a child and that all pedophiles will commit this offense. In both cases that is, at best, a half truth. The DSM-5, which is a tool that outlines the diagnostic criteria for a given disorder, defines pedophilic disorder as, “a paraphilia involving intense and recurrent sexual urges towards and fantasies about prepubescent children that have either been acted upon or which cause the person with the attraction distress or interpersonal difficulty.” With the latter half of this definition, we begin to open up to the idea that there are those who have sexual interests in children who have had no form of inappropriate contact with a child, but rather just have their daily life affected by the feelings that they are having toward

Most psychological research on the personalities of pedophiles consists of only clinical descriptions and case presentations. Bell and Hall represented the clinical approaches to the study of the personalities of pedophiles. They analyzed the dreams of a pedophiles and made suggestions about their characteristics. “ The inference from their case report was that pedophiles have a basic character disorder shown by schizoid and passive traits as well as a severe dread of adult sexuality.”(Bell & Hall 1971).

Annotated Bibliography: In this article, the author is making an argument that sexual abuse causes brain development problems in the long run. These children gain “a less flexible state of equilibrium” (Gaskill 37). They then become poor socialized and have problems in regards to emotional and physical health. In order to these children, they need to be helped immediately,

Due to its primary role in processing memory and emotional reactions, over the last decade and a half psychologists have been linking the amygdala to psychopathy. It is involved in aversive conditioning and instrumental learning and is thus involved in all the processes that, when impaired, produce the same functional impairments displayed by psychopaths. Two famous studies conducted by Tiihonen and Kiehl respectively have confirmed this. Tiihonen used a volumetric MRI to test and confirm the positive correlation between low amygdaloid volume and a high degree of psychopathy in violent criminals (measured by the Hare checklist-revised) while Kiehl used a functional MRI to prove reduced amygdala response during an emotional memory task in individuals who scored high on the Hare checklist-revised. However, both these studies along with numerous others were conducted using violent offenders as subjects rather than individuals with psychopathy. Although many psychopaths do exhibit violent tendencies, not all violent offenders are necessarily psychopaths. A study conducted by Raine is one of the few that did focus only on individuals exhibiting psychopathy. In his study Raine was able to show reduced prefrontal grey matter in his test subjects. Unfortunately though, he was unable to differentiate between grey matter in different regions of the prefrontal cortex. It is however clear that there is one region of the frontal cortex that could be

The limbic system was first recognized due to Franz Josef Gall (LeDoux, J., 1996). Franz Joseph Gall developed the idea of “phrenology” that focused on the study of the different variations of bumps on the human skull to be related to differences in behavioral and emotional functioning. The limbic system’s main function in the brain is to control emotional behaviors and certain forms of memories that are infused with emotion (amygdala). The amygdala is a part of the brain that forms the tail end of the basal ganglia within the rostral temporal lobe and is located near the hippocampus (Lambert, K.G. & Kinsley, C .H., 2005). The amygdala, as defined by the text, is an almond-shaped structure that functions as a part of the limbic system involved in regulation of emotion and sexual urges (Lambert, K.G. & Kinsley, C .H., 2005). In addition, the amygdala is comprised of a dozen or more sub regions that are not all involved in fear conditioning (LeDoux, J., 1996).

The importance of the amygdala in social cognitions has been examined in both primate and human studies. Use of primates to study the social brain suggests that the amygdala contributes to social cognition. Kluver and Bucy made large bilateral lesions in monkey brains made across the amygdala, temporal neocortex, and surrounding structure. After the lesion, the animals engaged in hypersexual behaviors, unusual tameness, and a lack of knowledge about emotional stimuli. Lesions exclusively targeting the monkey’s amygdala resulted in similar, but more subtle impairments. This suggest that the amygdala may play a role in emotions elicited by social cues. Studies of the amygdala’s role in human social cognition suggest that the temporal lobes process socially relevant facial information from humans. Emotions from facial expressions, in particular fear are projected to the amygdala. Studies using FMRI to examine typical subjects and subjects with amygdala damage support this theory. Individuals with amygdala damage have difficulty recognizing facial expressions, specifically negative emotions such as fear.

The three common classifications of pedophiles include: the secretive pedophile, the child pornography collector, and the active pedophile. The secretive pedophile is the most benign; he or she is the person who might become sexually aroused by a child, but never acts upon it. The pedophile who collects child pornography obtains sexual gratification from viewing photos of children. He or she might never act upon those desires by approaching a child, but their need to possess more and more illicit images can be seen as further violating children that are physically abused by molesters and rapists. Finally, the active pedophile is the most dangerous. He or she is physically harming children for their own sexual pleasure, and they are also the ones who photograph or video the crimes (Knetzger & Muraski,

According to “Psychology Today”, “Pedophilia is considered a paraphilia, a condition in which a person's sexual arousal and gratification depend on fantasizing about and engaging in sexual behavior that is atypical and extreme. Pedophilia is defined as the fantasy or act of sexual activity with children who are generally age 13 years or younger. Pedophiles are usually men and can be attracted to either or both sexes. How well they relate to adults of the opposite sex varies” (Psychology Today). Most children are abused by someone close to them like a family member, friend, or neighbor. There are many different affects that happen to children when they are abused. Many children that are sexually abused face the risk of having many psychological

In 2002 the Catholic Church was rocked with scandalous reports of Priests sexually molesting young children and particularly boys. The scandal is the result of numerous investigations, allegations, arrests, trials, convictions and imprisonment of Catholic Priests. It became largely reported that once trusted and respected Catholic Priests were pedophiles. The Diagnostic and Statistical Manual of Mental Disorders (DSM) categorizes pedophilia as a mental disorder if the sexual fantasies or urges involve prepubescent children , if they last six months or longer, if the individual has acted on them, or if they cause marked distress” (American Psychiatric Association, 2000).

Some argue, "the reality is that the overwhelming majority of offenders have a psychiatric illness, and to argue that sexual offenses are symptoms of some diagnostic category, only provides them with an excuse to minimize their responsibility for their own behavior." (Briggs 15). Others maintain that there are genetic and developmental factors which contribute to pedophilia being a disorder, although this theory has not yet been proven.
