Behavioral Psychology And Human Behavior

Modern biology is focused more on understanding behavior, like violence and crime, through research on indicators and influences. Rather than attempting to determine a single root cause, researchers are discovering markers of predisposition and identifying factors of risk. In a recent interview about his new book, The Anatomy of Violence: The Biological Roots of Crime, criminologist and professor at the University of Pennsylvania, Adrian Raine asserts that there is a “biology of violence” that should not be ignored; “Just as there’s a biological basis for schizophrenia and anxiety disorders and depression… there’s a biological basis also to recidivistic violent offending” (Gross, 2013).

However, more recently, a study led by King’s College London has claimed that there are differences between the brains of psychopaths and other criminal offenders diagnosed with antisocial personality disorder. Dr. Nigel Blackwood who led the research is quoted as saying “We describe those without psychopathy as 'hot-headed' and those with psychopathy as ‘cold-hearted’.” This statement shows a clear distinction between what should be interpreted as a lack of self-control and ability to repress impulses and what should be diagnosed as psychopathy.
The study took MRI scans of 66 men, two thirds of which were offenders who had been diagnosed with antisocial personality whilst the other third were non-offenders considered to not have any personality disorders. Of the 44 offenders, 17 met the diagnosis criteria for psychopathy (ASPD+P) assessed by the guidelines stated in the DSM-IV. Researchers saw that the members of the study diagnosed as psychopaths had notably less grey matter in areas associated with moral behaviour and understanding other peoples’

The brain can be affected by damage and cause behavior to be expressed differently in every person. Events such as a car crash or childhood abuse can affect brain development and function. Damage to certain areas of the brain can have a variety of effects. The hippocampus controls emotions and is associated with memory, and the frontal lobe is a brain cortex that controls motor functions, problem solving, memory, language, judgments, social and sexual behavior and impulse. When the frontal lobe or hippocampus is affected, a person’s emotion can be out of their control. In criminal cases, brain damage can affect the sentencing of a violent criminal, but to what extent should these abnormalities play a role in their conviction? Much research has been conducted in order to determine the effect that brain abnormalities should have on the conviction of violent criminals. A psychiatrist at New York University, Dr. Lewis, has conducted a study on death-row inmates, how their brains work and what affect the damage had on their conviction. By doing so Dr. Lewis paved the way for other researchers, such as Kent Kiehl and Jonathan H. Pincus to study the brains of violent criminals looking for a answer as to whether or not these criminals should be incarcerated. Over time research has been conducted focusing on mental illnesses and brain damage as the cause of violent acts instead of it being just premeditated murder. Many believe brain damage or mental illness should have no affect on

Overall, this article describes numerous cases of people’s personality and behavior being drastically affected by various forms of brain damage, particularly to the frontal lobe. This is consistent with what we have learned about Phineas Gage and his dramatically changed personality. As such, the author, David Eagleman, concludes that humans are not really “free” and that we are all products of our brains’ physical state, meaning that the notion of all humans being equal in their decisions is fundamentally flawed. He therefore proposes modifying the criminal justice system so that sentencing is customized more for the particular offender, taking into account the functionality of the criminal’s brain,

First attributed to Aristotle was the concept of the tabula rasa, or blank slate. He believed that a person was born pure and their interactions with the world shaped their persona. From the moment we are born, we observe the world around us and, for good or bad, retain bits and pieces that collectively make up our personalities. In the video Inside the Killer’s Mind, neurologist Dr. Jonathan Pincus posited that brain damage coupled with a history of abuse could result in aggressive behavior. “The violent ones were all neurologically impaired on examination.” He discussed a cyst found on Shawcross’ MRI in the temporal lobe that by itself wouldn’t necessarily be significant, but coupled with an EEG spike in the same area it indicated an abnormality. Also in the film, Dr. Dorothy Lewis stated that in her exams of violent children she “found that these kids had more accidents, injuries, illnesses and hospitalizations than other kids.” I believe that brain injuries and abnormalities could account for elements of personality that are attributed to empathy, inhibition and moral concepts; characteristics sometimes lacking or poorly displayed in those with criminal behaviors.

This documentary specifies that there is no easy answer to what is going on inside the mind of killers, and we cannot simply place these individuals into “neat diagnostic boxes” that explain why their actions turned so violent. However, the investigators present research studying different avenues regarding ways to “predict” the likelihood that an individual will commit violent crime, will maintaining that no method is perfect. Throughout the presentation, viewers are offered mountains of research highlighting a mix of nature and nurture ranging from neurologists from Harvard studying brain patterns affected by genetics, to psychologists studying maternal care and attachment during infancy.

The injury sent a three-and-a-half foot-long tamping iron into his head, shattering his upper jaw and destroying his left ventromedial frontal cortex. Phineas Gage recovered from his brain injury, but his personality underwent a dramatic change described by those who knew him as a Dr. Jekyll/Mr. Hyde transformation. In more modern times we have seen similar results from brain injuries with Antonio Damasio, who had his left and right orbit and lower mesial cortices, including the prefrontal area, removed due to cancer. While he recovered from the surgery, his personality, like Phineas Gage’s underwent a dramatic change and his ability to morally judge situations became poor leading to a demise in his life and relationships. These cases have shown that damage to the frontal lobe changes how a person thinks and acts. We have seen that deficits in the frontal lobe are also commonly seen in people who are depressed, who experience chronic stress, in suicide victims, sociopaths and in incarcerated criminals. Since we can see that these brain changes affect personality and even life choices, it is not that far fetched to think that these same brain defects can lead to criminal behavior. For example, the prefrontal cortex is an area of the brain that acts to receive input from other areas of the brain and uses this information to make decisions. If this area is

It is very rare to study something that is as fascinating yet as bewildering as the distinctive paradox, that is the human brain. Every individuals conflicting behaviour and elaborate character that make them the person they are must have a justification. I originally established a fascination in forensic psychology as I read about a sequence of homicides committed by Gary Ridgway, otherwise known as the “Green River Killer”. Upon discovery of this case, questions began to pervade in my head about what may be the cause for an individual to execute such things, and just how someone’s mind could be so peculiarly dissimilar to my own.

The principles and theories of Social Psychology are important and useful in assessing behaviors in situations. These social psychological principles and their applications can be seen in fictional films which can also be attributed to everyday life. One such film that holds certain social psychological perspectives is Will Gluck’s 2010 production of Easy A. A film about high school student Olive Penderghast and how a sudden change in popularity and financial status, after an unintentional rumor about how she supposedly lost her virginity to a college guy spread through the entire her school. The film draws on the behavioral connections of pronounced hussy Olive Penderghast and her English class’s assigned reading of The Scarlet Letter.

The biological theories are an essential to criminal justice professionals to explain why the genetic characteristics of the human being's body chemicals and evolutionary aggressive criminal conduct have been proposed as explanations for crime; however, to distinguish criminals from non-criminals without adding the value judgment. (Bohm & Vogel, 2011) “Biological theories can be understood as a broad, science-based, anthropological approach to understanding criminality” (Swan, 2017, para. 4). It is important to understand the body type based on the functions of the brain. Therefore, there are several different methodologies to describe the physical differences between criminals and non-criminals such as physiognomy, phrenology, criminal anthropology, the study of the body types, heredity, and scientific technologies that examine the brain function and structure to give the criminal justice profession another look into an individual before a biased take.

The purpose of this essay is to outline and evaluate at least three psychological perspectives of human behaviour. The three approaches that will be summarised are humanistic, social learning theory and the Biological approach. They will also be criticised and compared to one another. A brief description on psychology will occur, and there will also be a short summarisation on some key early influences of psychology, from its origins in philosophy.

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

I also agree that management has to be able to change and grow and continue to listen to any upward communication from the staff. In order to accomplish better communication, management should provide an ‘open-door’ policy and also informal meetings where employees can either feel free to go to their supervisors first with any questions or concerns and also raise issues with resources or basically anything that interferes with their job performance (Newstrom, 2014, p. 70).

When looking at criminal activity and the direct connection to the criminal behavior we see that there have been many research trials that have taken place over the history of humankind (Mishra & Lalumiere, 2008). Two of these research areas that have been developed to attempt to understand the causes of criminal behavior are known as biological and psychological perspectives of crime causation. These two sectors have their principles that are held in their theories as a standard scientific understanding of the basics that each evaluation of criminal behavior is built on (Dretske, 2004).

It is very rare these days to turn on the news and not hear about a crime or a murder. Crime is a common occurrence yet many times it is difficult to understand how someone could bring themselves to do these things. It does seem to make any sense why a young handsome man from a good family would want to kill someone and then be able to go through with it. This leads one to wonder if the brains of people who behave in socially unacceptable ways are different from everyone else's brains. There is a substantial amount of evidence that suggests some criminals do have differences in their brains that most likely contribute to their behavior. Many of these individuals have Antisocial Personality Disorder and
