Week 4 – Assignment: Summarize the Two Main Theories of Sex Differences in Aggression Turnitin originalitycheck enabled

This week, you have examined theoretical principles of sex differences in aggression: sexual selection and gender role. For this task, you will reflect on what you have learned about sex differences in aggression. Now assume that you have been asked to prepare an article for an online journal that focuses on aggression and behavior, but first you need to complete an interview with a leading expert in sex differences in aggression. Begin by selecting your expert and complete a mock interview that asks and answers the questions below.

  1. Explain sexual selection theory and gender role theory. What are the main principles of each theory? What position is taken by each theory on the origins, development, and causal mechanisms of aggression?
  2. Give an example of aggressive behavior that may be explained from the perspective of sexual selection and from the perspective of social role theory that is not covered in the reading.
  3. Discuss at least one psychological phenomenon that may influence displays of aggressive behavior as explained by the sexual selection theory and the social roles theory.

Support your interview with at least two references from peer-reviewed journal articles. Remember to cite your information and references in the proper APA format.

Length: 3-4 pages

Your paper should demonstrate thoughtful consideration of the ideas and concepts presented in the course by providing new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards.

John Archer School of Psychology, University of Central Lancashire, Preston PR1 2HE, United Kingdom jarcher@uclan.ac.uk http://www.uclan.ac.uk/scitech/research/rae2008/psychology/ staff_pro?les/jarcher.php Abstract: I argue that the magnitude and nature of sex differences in aggression, their development, causation, and variability, can be better explained by sexual selection than by the alternative biosocial version of social role theory. Thus, sex differences in physical aggression increase with the degree of risk, occur early in life, peak in young adulthood, and are likely to be mediated by greater male impulsiveness, and greater female fear of physical danger. Male variability in physical aggression is consistent with an alternative life history perspective, and context-dependent variability with responses to reproductive competition, although some variability follows the internal and external in?uences of social roles. Other sex differences, in variance in reproductive output, threat displays, size and strength, maturation rates, and mortality and conception rates, all indicate that male aggression is part of a sexually selected adaptive complex. Physical aggression between partners can be explained using different evolutionary principles, arising from the con?icts of interest between males and females entering a reproductive alliance, combined with variability following differences in societal gender roles. In this case, social roles are particularly important since they enable both the relatively equality in physical aggression between partners from Western nations, and the considerable cross-national variability, to be explained.
