Another part of the brain that factor into criminal behavior is the amygdala, which is involved in fear, aggression, and social interaction. Additionally, imbalanced levels of testosterone, dopamine, and serotonin may contribute to criminal behavior. The anterior cingulate cortex ACC , which is heavily involved in behavior regulation and impulsivity, could also be a contributing factor.
Researchers have proposed various theories examining social and environmental factors that influence or drive individuals to commit crime.
Some theories point to elements like neighborhood dynamics, pressure caused by cultural goals and social structures, and the development of subcultural systems as the reasons for criminal behavior. Other theories suggest factors like rational choice, feelings of being unfairly disadvantaged compared to peers, and various biological and social elements as criminal influences.
A key psychological theory is behavioral theory, which postulates committing a crime is a learned response to situations. Another prime theory is cognitive theory, which explores how individuals solve problems through moral development and information processing. Psychological theories scrutinize personality traits like extraversion, neuroticism, agreeableness, openness, and conscientiousness when examining criminal behavior.
Additionally, they examine the concept of the psychopathic personality, where an individual may engage in criminal thrill-seeking behavior to compensate for low arousal levels. Studies indicate that personality traits of hostility, narcissism, and impulsivity correlate with criminal and delinquent behavior. As more research is conducted to understand the criminal mind, forensic psychologists will be able to apply these findings to aid the criminal justice system in understanding and prosecuting delinquent behavior.
Social and community service managers will work alongside the criminal justice system to identify community needs and implement programs to help prevent and respond to crime. Individualists tend to focus on personal weakness as the reason a crime is committed. If someone chooses to offend, that is their responsibility and if caught, they should suffer the consequences.
Individualists believe that if punishments were stronger and the police and courts had more powers, there would be less crime. Collectivists feel that society is unequal and some people are at greater risk of being influenced by criminal behaviour, often through the actions of parents or friends. In order to tackle crime, collectivists feel that social conditions which create the catalyst for crime need to be addressed.

Many inmates on death row have histories of some kind of severe abuse. The neglect and abuse of children often progresses through several generations. The cycle of abuse, crime, and sociopathy keeps repeating itself. Children who are neglected or abused commit substantially more crimes later in life than others.
The cycle of violence concept, based on the quality of early life relationships, has its positive counterpart. Supportive and loving parents who respond to the basic needs of their child instill self-confidence and an interest in social environments.
These children are generally well-adjusted in relating to others and are far less likely to commit crimes. By the late twentieth century the general public had not accepted that criminal behavior is a psychological disorder but rather a willful action.
The public cry for more prisons and tougher sentences outweighed rehabilitation and the treatment of criminals. Researchers in the twenty-first century, however, continued to look at psychological stress as a driving force behind some crimes.
Searching for the origins of antisocial personality disorders and their influence over crime led to studies of twins and adopted children in the s. Identical twins have the exact same genetic makeup. Researchers found that identical twins were twice as likely to have similar criminal behavior than fraternal twins who have similar but not identical genes, just like any two siblings.
Other research indicated that adopted children had greater similarities of crime rates to their biological parents than to their adoptive parents. These studies suggested a genetic basis for some criminal behavior.
Prisoner in California being prepared for a lobotomy in At the time, many psychiatrists believed that criminal behavior was lodged in certain parts of the brain, and lobotomies were frequently done on prisoners. With new advances in medical technology, the search for biological causes of criminal behavior became more sophisticated. In psychologist Robert Hare identified a connection between certain brain activity and antisocial behavior. He found that criminals experienced less brain reaction to dangerous situations than most people.
Such a brain function, he believed, could lead to greater risk-taking in life, with some criminals not fearing punishment as much as others. Studies related to brain activity and crime continued into the early twenty-first century.
Testing with advanced instruments probed the inner workings of the brain. With techniques called computerized tomography CT scans , magnetic resonance imaging MRI , and positron emission tomography PET , researchers searched for links between brain activity and a tendency to commit crime.
Each of these tests can reveal brain activity. Research on brain activity investigated the role of neurochemicals, substances the brain releases to trigger body activity, and hormones in influencing criminal behavior.
Studies indicated that increased levels of some neurochemicals, such as serotonin, decreases aggression. Serotonin is a substance produced by the central nervous system that has broad sweeping effects on the emotional state of the individual. In contrast higher levels of others, such as dopamine, increased aggression. Dopamine is produced by the brain and affects heart rate and blood pressure.
Researchers expected to find that persons who committed violent crimes have reduced levels of serotonin and higher levels of dopamine. This condition would have led to periods of greater activity including aggression if the person is prone towards aggression. In the early twenty-first century researchers continued investigating the relationship between neurochemicals and antisocial behavior, yet connections proved complicated.
Studies showed, for example, that even body size could influence the effects of neurochemicals and behavior. Hormones are bodily substances that affect how organs in the body function. Researchers also looked at the relationship between hormones, such as testosterone and cortisol, and criminal behavior.
Testosterone is a sex hormone produced by male sexual organs that cause development of masculine body traits. Cortisol is a hormone produced by adrenal glands located next to the kidneys that effects how quickly food is processed by the digestive system. Higher cortisol levels leads to more glucose to the brain for greater energy, such as in times of stress or danger. Animal studies showed a strong link between high levels of testosterone and aggressive behavior.
Testosterone measurements in prison populations also showed relatively high levels in the inmates as compared to the U.
