In a questionnaire, if women reported that their partner did not like them talking to other men, they were twice as likely to report violence from their male partner.
Studies on battered women have shown that extreme jealousy of their partner as the main cause. Under this explanation Uroxide is an unintended consequence of the evolutionary adaptation designed to control, not kill.
Support for the explanations comes from a study in the USA involving men and women that were all in committed heterosexual relationships. Men were asked about their use of mate retention techniques and how often they used 26 different types of violent acts, women were asked similar questions.
From the male responses negative mate retention techniques were positively correlated with violence scores. Results for women were similar.
The idea that uroxide was unintentional was challenged by Shakelford. A strength of the research is this area is its practical applications. Particular use of mate retention techniques can be an early indicator of violence towards partner, alerting family, friends and partner to possible danger.
You can sort the problem out before violence occurs. A second evolutionary explanation of human aggression is the evolution of homicide.
One cause of aggression could be a lack of resources. So, the inability to attract a long term partner and a lack of resources appears to lead to social competition and therefore aggression. A second cause of aggression could be status. In the EEA, we used to live in small groups and status was very important.
A loss of status could have had catastrophic results on reproductive potential and resources. Although this is not the case now, the gene may still exist, so there has been a genome lag which is causing aggression in humans. A third cause could be sexual jealousy. A weakness of this explanation is that it cannot explain why people respond differently when face with the same situation.
For any evolutionary explanation, a limitation is that it cannot be falsified because you cannot go back to the EEA and see if the behaviour has really evolved, so you cannot prove or disprove an evolutionary explanation of human aggression.
A limitation of those explanations are that they are both reductionist and deterministic. Assuming the aggression is simply caused by your genetic make up or because its adaptive to be aggressive is too simple.
It ignores other factors such as culture which has shown to cause aggression as a result of socialisation e. Discuss the role of neural and hormonal mechanisms in aggression. Testosterone has been linked to aggression and as it plays a part in increased muscle and bone mass, this suggests that it plays a structural role in influencing aggression.
Testosterone has been shown to correlate with the level of aggression displayed by humans and animals. For example when levels of testosterone peak around the start of puberty there is also a corresponding level of aggression displayed in young males during this time.Evolutionary psychologists attempt to understand human behavior by studying the role of evolutionary pressures on modern humans.
One of the most interesting areas of study for evolutionary psychologists is human aggression. According to Live Science, humans are one of .
