Klinesmith, Kasser and McAndrew simultaneously studied the links between guns, (objects associated with aggression), testosterone levels in males, and aggressive behavior. They hypothesized that males who interacted with an object associated with aggression would have an increase in both testosterone and aggressive behavior. To test this hypothesized they asked 30 college males to provide clean saliva samples before the experiment that would act as the baseline measurement of testosterone. The participants were told the experiment was about taste sensitivity. After the saliva sample was taken the males were asked to interact with either a gun, or a children’s toy. Then a researcher took another sample of saliva, and asked the participant
He demonstrates that in monogamous species male testosterone levels should only rise above the baseline breading level in response to social challenges, such as male-male aggression or threats to status. Since we are a monogamous species we can predict that male testosterone levels would rise sharply in response to such challenges. Therefore if a testosterone surge is expected to be found when males are challenge then we can expect a consequent increase in aggression, provided the threat is deemed relevant to reproductive competition (a dispute over women). Since this study is based on all monogamous species as a whole, one could question whether or not it can be extrapolated to the human race, as we would be comparing ourselves to animals like monkeys, when we know that we are more superior to them. However it does show that monogamous males are more likely to act aggressively when facing a threat to their reproduction, this aggression seems to be coming from the increase of testosterone which happens because of the confrontation. Another problem with this hypothesis is that in modern day some men aren’t always monogamous, especially younger men, so if this theory were true single men would have no reason to become aggressive, which Lindman proves wrong with his study, therefore the theory is outdated and no longer applies to most men.
I think it would be beneficial to test these men alone as well as in a group with other men and then with a woman as well,
Testosterone is a hormone in both men and women, but in greater extent in the men, testosterone is a chemical compound (C19H28O2) and is responsible for the characteristic of men such as, sexual characteristics/sexual organs, deepening of the voice, and facial and body hair. (Neil Schlager, Jayne Weisblatt, and David E. Newton 2006) Testosterone/Steroids has bodybuilding and masculinizing effect as well as treating a variety of medical conditions, like asthma, the steroid is used in a puffer, they can be used for anabolic or androgenic purposes and made for synthetic purposes making them illegal. (BROWER, K. J. 2001) Many athletes will use these to gain an advantage on competitors, with lean muscle and higher endurance, with many uses, there
America is very unique as a country especially during the prosperous times of peace, the country is frequently undergoes drastic political and social changes usually seen in other countries only in times of war such as NAZI Germany or Republic people of China. Since the revolution won the independence of America nearly 200 years ago, America has undergone change after change. The use and abolishment of slavery, the tolerance and rejection of immigration, the Homestead act and giving tracts of land and the vote to thousands of people who did not have before, are all examples of the big changes this country. These changes, although large and important in their rights, only increase, decrease, or a little redistribution of political power in the big picture of all
Aggression is a natural part of human behavior, and can even be adaptive in certain situations. However, when aggression manifests itself in violent behaviors, it becomes problematic. Patterns of aggression change throughout childhood, adolescence, and early adulthood, and these changes usually differ between males and females (Loeber, 1997). Physical aggression is typically greatest early in life and decreases during adolescence, whereas more serious violence tends to increase with age, particularly during adolescence (Loeber, 1997). Despite the changes that occur in aggressive tendencies throughout childhood and adolescence, aggression is seen as a very stable trait, almost as stable as
Task 1: (POWERPOINT) Task 2: Evidence for the evolution explanation of aggression: 1. Wilsons study found evidence of direct guarding as mate retention; in women reporting partners used this tactic. (E.g. who they speak to, allowing to talk to other men) 72% required medical attention after an assault by their partner. 2. Those who think evolution has made humans naturally peaceful and those who think we’re more naturally prone to violence (organizer Elizabeth Cashdan).
An example of verbal aggression was, "Pow!" and "Sock him in the nose". After ten minutes the experimenter entered and took the child to a new room which the child was told was another games room. In stage two (Aggression Arousal) the child was subjected to 'mild aggression arousal'. The child was taken to a room with relatively attractive toys. As soon as the child started to play with the toys the experimenter told the child that these were the experimenter's very best toys and she had decided to reserve them for the other children. In Stage three the next room contained some aggressive toys and some non-aggressive toys. The non-aggressive toys included a tea set, crayons, three bears and plastic farm animals. The aggressive toys included a mallet and peg board, dart guns, and a 3 foot Bobo doll. The child was in the room for 20 minutes and their behavior was observed and rated though a one-way mirror. Observations were made at 5-second intervals therefore giving 240 response units for each child. Other behaviors that didn’t imitate that of the model were also recorded e.g. punching the Bobo doll on the nose. Bandura thus observed children who observed the aggressive models made far more imitative aggressive responses than those who were in the non-aggressive or control groups. There was more partial and non-imitative aggression among those children who has observed aggressive behavior, although the difference for non-imitative aggression was small. The girls
There are various different factors that influence aggression in both children and adults. More so, significant research has proven that there are distinct differences between aggression shown by men and women. Aggression is behavior intended to harm another individual, and extreme cases on aggression is called violence. In 2010, 90% of murderers in the United States were male. Numerous researchers have found that the gender differences in aggression are astounding, and that males show aggression a significant amount more than females. These differences are primarily because of what we learn, and what we experience throughout the lifespan. It is true that both males and females learn aggression through learning and experience, but the way
Felson’s (1982) examination of self-reports revealed some interesting and somewhat unpredicted results. In support of his hypothesis, it was found that an insult increases the odds of a verbal dispute 3.2 times when the respondent is male, and 2.2 when female. Furthermore, a highly significant three-way interaction was found involving severity of outcome, sex of respondent and sex of antagonist. This showed that hostilities are more likely to involve physical violence when males conflict with other males. The odds of a physical dispute versus a verbal dispute increases 2.1 times when both parties are male, as opposed to both female. The likelihood of physical versus verbal dispute for two males is 4.3 times more likely than for cross-sex conflicts. These significant
One theory that prompted research on how boys and girls differ in the expression of aggression was that boys are more aggressive than girls’ theory. Several researchers in the past suggest that boys act in aggressive way within the peer group context for physical dominance (Crick, gropeter 2012). The idea was the exploratory examination of gender differences in patterns of association between physical aggression and the social interaction revealed that the relationships were only true for boys. In other word,
Biology focuses its attention on genetically inherited forces in and attempt to explain aggressive and violent human behavior. For example, studies in the 1960s focused on XYY Chromosomes in males in comparison to the normal XXY chromosomes among male inmates. At the time, researchers found that men born with the XYY syndrome were more populous in the inmate population and were bigger and more aggressive than those with the normal XXY Chromosomes (Alder, Laufer, & Mueller, 2013, p.82). However, such finding did not take into account environmental factors associated with the XYY syndrome to be able to fully determine genetics as the culprit when some individuals were law abiding while others are violent (Alder, Laufer, & Mueller, 2013, p. 82).
Violence tends to be a simple solution that everyone comes to at some point in their life. It's a basic principle of being alive to fight but of course there’s a limit. I am going to identify at least three of the crime causation theories that may apply to this case. The first theory is biology and a brief example of a new genetic screening. The second theory is how testosterone could be a cause of this violence. The third theory is how rational choice theory could be a cause of the violence in people.
There are clearly no simple genetic or hormonal factors that can explain the variation in aggressive in males and females. Studies of human males suggest that there is at most a small genetic component to aggression, but a greater one for personality traits associated with such behavior. The biological mechanisms translating the message in the genes into antisocial or criminal behavior are not known. Therefore, there is clearly no simple aggressive gene effect. Many genes are likely to be involved, and each may have a weak effect on aggressive behavior. A direct genetic effect on aggression, for example, may determine how quickly an individual responds to aggravation. Aggression may also be influenced indirectly; for example, a man's size and strength may affect the way he behaves and how others react to him. (Turner, 253)
There are two potential sources for CH4 emissions in the algae pathway, the AD process and biogas clean-up. Based on a literature review (Liebertrau, et al., 2010; Flesch, et al., 2011), we assume a total fugitive CH4 loss of 2% for this pathway. Biogas flaring efficiency was observed to be less than usually expected, averaging 81% CH4 combustion in the flare with a range of 48% to 99%. This range is usually assumed to be 90% to 95%. However, the N2O emission from the N-containing sludge was ignored because chemical fertilizers replaced by the biogas residue are associated with the same issue.
Lavinia et. al. (2010) describes a study that calculated physiology factors on a person’s predisposition to aggression in intimate relationships. The study looked at physiological reactivity, which is defined as changes to a person’s body brought about by a stimulus. The study found that individuals that are antisocial and violent are
