Trait Theories....Validity or Not?


Comments

  1. When discussing Bio-criminology we are looking at the biological factors that cause individuals to commit delinquent acts, instead of the social factors. Lately we have been discussing things like how environment and the people in that environment have an effect on your choice to commit crime. Things like low serotonin levels in the human body and having an underdeveloped prefrontal cortex are reasons why some people find it easy to turn to crime. Parental guidance is also risk factor that could lead an individual to commit crime. Bad parenting can cause a child to assert anti-social behavior and other negative effects. Although social theories help criminologist explain why crime occurs, studying a persons biological factors can too. Usually, these biological risk factors are caused from events that someone has experienced and it has the most effect on person from childhood to adolescence. The effect it has on the person depends on when it happened in their life and when. Bry001

    1. I agree the factors mainly consists of societal factors, but also I agree biological factors can have a huge impact on an indivuals personality and choice making skills while growing up. Also, their was a good point that events that had a traumatic event in childhood lead up to a lot of the delinquent choiceing a person may make. Eagle001.

    2. I also think that a lot of the factors that go into committing crimes is mainly societal factors but a lot of these bio criminology theories make sense. I found it interesting that some of these biological examples were triggered from experiences at a young age and carried on to adolescence. I feel as if when these events or risk factors happen to a child it would have a bigger effect than if it happened to someone in their early adult years. Bike001

  2. Moffitt's idea of delinquency is interesting, she claims that delinquency can be caused by adnormal brain development. This can be from lack of the proper diet, drug use, or abuse. These factors play into delinquency which makes sense because if someone didn't have the proper diet this would throw off brain activity. This was an interesting idea pointed out in the video that some people have low heart beats this factors in to make it where an indivudal might try to commit an criminal act to feel a rush. Someone might also try to commit a deviant act in order to raise their serotoin levels. Eagle001.

    1. Each one of the risk factors causing abnormal brain development happens at different stages of a persons life. Like you mentioned, drug use and physical abuse can lead a person to a pathway of crime. Abuse typically occurs in a persons life during childhood and sometimes adolescence. This is when a person is most vulnerable to being mentally traumatized by the incident. Drug use will occur in the later teenage years and sometimes earlier than that. Just one of these risk factors can cause a person to turn to committing crime. Unfortunately, there is not really a way we can prevent a traumatic event or bad influence from occurring in a persons life. Bry001

    2. I don't know about proper diet and the effects of crime. I just don't see a true correlation in the two. The correlation may in fact be that people who live in low income areas don't have money for high end healthy food. I think their is probably a bigger correlation between being able to just feed your family then having the affluence to buy nice organic and health conscience foods. Just because my family buys the PSST brand at Kroger doesn't mean my kids are gonna rob a bank. Dadoftwo001

    3. I agree with you on this because if you might have a problem you are likely to commit crime but if you don't you have 50/50 chance on committing the same crimes as those with the certain problems do. But all in all I think people with problems are just doing what they got to do. Golfer001

    4. I also think that this is an interesting point, but I also think that there are other theories that may explain criminal behavior a little better than this one. I think that those with a medical disability/problem may be more likely to get involved with crime, but I also think that outside factors such as the individual's peers may have a greater influence than their condition alone does on whether or not they start committing criminal acts.

    5. I agree i dont think it has anything to do with diet is think its more on the parents and the kids free who the kids hang with have impacted how they acted were you grow can have an effect cowboys001

  3. I would say biological factors play a role in why people commit crime. I think that those are contributors to the reason that people commit crime but I don't want to lump everyone who has low serotonin levels and a irregular heart beat to crime. I think that they are more of a contributor to committing crime but lets not look for a medical excuse for people who commit crime. Also in this article their are talks about trauma or abuse their is just as much evidence that says that when people are victims of abuse or trauma they want to protect other victims not hurt them. So I will admit that sometimes their are probably some brain issues but most people seem to know what they are doing is not right, but chose to do wrong. Dadoftwo001

  4. I think that people with some brain things might get into less violence then people with heart problems. I also think that people will commit crimes if they have some problems with them, but some may not because they really can't do anything if they brain and heart problems. Low heart beats and serotonin are going to commit crimes and raise heart rates and serotonin levels. If that happens I wouldn't be surprised to see if that stuff really happens but it would be really bad for a lot of people to see those people that have those diseases do that and I would hate to see a lot of people die.

  5. I dont know if i believe in all this because i knew people with had low iq and low this low that and never committed a crime before knew someone that had noting wrong with them commit a lot of crime yes people with low iq low levels probably do commit more crime them others i seen that first hand but i mean when it comes down to it in less someone has some real mayor issues it really comes to free will and choose i personally know the affects of haven low chemical imbalance it really does make things hard in life but i can say most of us know right from wring cowboys001

    1. I tend to agree with you cowboys001. Just because someone has a low iq doesn't mean they will turn to a life of crime. There are numerous contributing factors to consider. Yes, I for sure think we all have free will. But juveniles are moresusceptible to peer pressure and that free will may go out the window, when they are concerned with being viewed as "cool" by their peers. But overall I don't think delinquency can be described as a biological issue, when it is impacted by so many other things as well. mommy001

  6. I think that biological factors do play a role in criminal behavior, but I don't think that it is a sole contributor. I feel that people with lower IQs or other health problems are more susceptible to getting involved with criminal activity, but I also think that there is more to it then that. I think peers of these people play a huge role in if someone with a medical problem will get involved with crime, because they may not know any better than to follow what their peers are telling them. There are a lot of outside factors I would place higher on the list of "things that cause people to get involved in criminal activity" than medical problems, but I am in no way discounting it as a reason.

    1. I agree with you completely. I think its their peers that make people more likely to commit crime more than any other reason in my opinion. Your peers have the biggest influence on you when you are growing up. But these biological factors are definitely a reason to why people commit crime.

    2. I also agree with you. I think that low IQs could contribute to a persons decision to commit crime because crime is a low IQ decision, but I don't think that being dumb is going to make someone a criminal. I also agree that crime is more of a learned behavior that is picked up from peers and is mostly a decision of the person committing the act. CoolGuy001

  7. I would think that some biological reasons do play a part in why people commit crimes. I also think that other theories contrtibute as well. We know that people in poorer economic areas commit more crimes. People who may have experienced some form of abuse or trauma may also fall into a life of crime as well. Depending on what peers they choose to associate with can also be a contributing factor as well. Every person is impacted differently by their circumstances. So it would appear that criminal activity is made up of various causes. Just because someone has a health problem doesn't mean they will become delinquent. Just as those who experience abuse don't always end up repeating the cycle of abuse. When looking at why juveniles become delinquent, I feel all the theories need to be considered. But would certainly say biological facors could play a role in contributing to a juvenile becoming delinquent. As well as their peer groups, their family history of committing crimes, the areas in which they live, etc. It is a combination of different factors that contribute to juvenile delinquency. What impacts one juvenile may have no bearing on the next. mommy001

    1. I agree with you mommy001, biological factors do play a role, and so do the other theories. There could be a mental illness, and a bad environment put together that just breaks a kid into being a delinquent. Life has a different impact on each person and we all have to learn how to roll with the punches and rise above. agentp001

  8. These trait theories were very interesting to learn about. The one that stood out the most to me was the gluecks theories on the form of a criminal. They said that criminals are more likely to have mesomorphic or muscular bodies. I found this theory interesting because when I think about crime or juvenile offenders I usually don't think about their physical appearance the first thing that comes to mind is the mental state of the offender. It Is very interesting to see that their research showed that it is more common for offenders to be buff and muscular. They also argued that offenders are more likely to be extroverts which to some could make sense because some delinquent offenders do things to show off or to be cool to fit in with a crowd.The Next point that the Gluecks made was that juvenile delinquents were more likely to have a lower verbal knowledge level than non delinquents. This could be caused by poor education which is another risk factor for juvenile delinquency. Bike001

  9. Its interesting to see how biological factors effect how a person commits crimes. This video did a great job discussing those theories. We see in this video that those who are delinquent do poorer in school. The Glueck theory was the one that stood out to me the most. IT said that the juveniles who were delinquent were more likely to have a lower verbal knowledge than those who are not delinquent.This is most likely because of they are doing poorer in school and probably not even going to school. The bio chemical theories of crime explain why some people commit crime, but I don't think its the main reason. These factors can make a person more likely to commit crime but not everybody who is like that commits crime. Its their environment and the people who they hang around with that effect them even more. But these biological factors do play a bug role in whether they are or whether they are not delinquent.

  10. I doubt that biological factors are going to have an incredibly significant impact on a juvenile's willingness to commit crimes. It may make them slightly predispositioned to crime, but most criminal acts would be due to social factors brought on by their mental issues. For example, children who are exposed to lead are likely to develope learning disabilities. These disabilities could make it hard for the children to learn and do well in school so they lose the gratification of good grades and teacher approval, so they seek gratification and approval through other possible deviant acts. Or they could have some gene that makes them quicker to anger or less patient than others, which could put them at greater risk of deviating in a social setting. Rowe's theory that juveniles will deviate in order to increase their low heart rate and serotonin levels seems unlikely because most children have easier ways to make their heart rates go up such as sports or physical exercise. Glueck's proposal that negative traits in children that cause them to become delinquent from parents with similar mental deficiencies sounded eerily like the ideas of eugenics proposed in the decades before their research was conducted. One would think that a child with problem parents may become delinquent due to how they were raised by those parents and not by what they inherited from them. Moffit's theories on how juviiles could be biologically influenced by things like early exposure to drugs, poor nutrition, and poor parental care could just be symptoms of a preexisting propensity to deviance through social influences like poor parenting and exposure to the influence of drug dealers. Also, her postulation that teenagers look up to lifetime offenders seems unlikely since people who commit deviant acts on their own without peer pressure are normally shunned in society, I remember in high school that people avoided those lifetime persistent offenders since they were considered weird. I am not trying to discount the theories proposed by these scientists, nor do I doubt that biological factors can influence propensity to crime. I only think that it is wrong to assume that biology is the main underlying factor in a persons decision to commit a delinquent or criminal act. CoolGuy001

  11. The biological trait theory is very interesting. This theory focuses on what might be physically wrong with someone. One aspect is biochemical, which focuses on factors like diet, hormones, and environmental containments. Neurophysiological is a second aspect, which focuses on the brain structure, brain chemistry, and neurological disorders. Genetics can also play a role in criminality according to the biological theory. The theory suggests that criminality is due to genetic factors and can be passed from parents to their children. Rowe has a large influence in the biological area. He did research that shows that violent antisocial individuals commonly had low serotonin levels. He also fount that individuals with low heart rated were prone to violence. Rowe believed that people with low serotonin and low heart rates would commit crime or partake in risky behavior to try to raise their serotonin levels and heart rates. He believed that these biological traits caused people to commit crimes, possibly to make them feel more normal. 7point62001

  12. I like how this video explains such a wide variety of trait theories starting out with Rowe's theory on how biology involves the criminal justice system which deals with biological and individual trait theories. Then the videos moves on to The Gleuk's theory of juvenile delinquency and argued with sociologist the individual trait theories should focus more than soicialogical factors. Mofitts individual trait theories basically explains a persons life course in which the environment that person was raised mainly with how the brain changed I adolescents over a period of time based on the individual trait theory. Overall I think this is a process of psychological and biological theories that involve a person involvement in criminal action especially to young individuals who were raised in these types of circumstances.

  13. The biological trait theory is very simple with actually might be wrong with a person. The biochemical and neurophysical aspects are the two main reasonings behind what could be wrong with someone. Biochemical is what consists of the persons diet and hormonal balances where as neurophysical focuses on the brains activity. Genetics is what makes the outcome of each of these aspects and has the choice to how the body makes decisions. If a parent is known to committing criminal acts then more than likely those genes where passed on to the child whiteout having any knowledge of deviance. Rowe believed that committing crimes could possibly be the reason for some people to feel like they fit in and follow their parents footsteps. Another big problem was the education and how well a kid maintained his or her self. Which also follows the parents life before cubs001.

  14. The Moffitt Trait Theory particularly caught my eye. Its crazy to think that an event in a persons childhood can stay with them their entire life. If the brain is exposed to early drugs, poor nutrition, injury, toxins, lack of stimulation, and other it with cause neuropsychological deficits. Its crazy to think that these brain deficits can cause the person to pursue crime for a majority of their lives.

  15. I think that biological factors have a huge part in why people commit crime. A lot of the time people who commit alot of violent crimes, like let's just take some of the shootings for example. A lot of those people are mentally ill and the chemical imbalance in their brain causes them to do things that "normal" people wouldn't do. I'm not using that as an excuse for what they do, also I do think mental illnesses are overused when putting someone on trail. I do also agree with Gluek alot of environmental factors cause people to go into the life of crime. Take someone who was raised in a not so good part of town and their father was a drug dealer and they have seen their father taken in and out of jail.. its 50/50 chance that the kid is going to go into a life of crime because that's all they know. It's just like teenage pregnancy if your mother was a teen mom most likely you are going to be a teen mom. -dicaprio001

  16. I thought that there was a lot of interesting information that was covered in the video. I do think that biological factors can play a role in if people commit crime or not. How your body is made up and what you have gone through can influence what decisions you make in life. I do believe that people with a low IQ at times could be more likely to commit crimes. They might not have the same thought process as people with a higher IQ and might not think twice about some of the things they do. I also believe there are many other things like drugs that can affect someone biologically as well. hawkshockey001

  17. Trait theories are always interesting. I think it's funny because most of the time you can describe an action or series of events using trait theories but it's not always correct. Most trait theories sort of rely on a singular cause or factor that plays into the out come which is just unlikely. You can't blame just the person or just the environment for the actions. You have to equally weigh the two and show the importance of looking at all the variables.
