Evaluation for hormonal explanations of aggression

• • Supporting evidence: The studies above suggest a positive correlation between testosterone and aggression.
• • Conflicting evidence: Although there is a lot of evidence supporting a link between testosterone and aggression, not all studies agree. For example, Tricker et al (1996) randomly assigned 43 men to receive either 600mg of testosterone per week or placebo but observed no differences in aggression between the two groups.
• social sensitivity- research we conduct on people may negatively affect their lives and people like them
• the use of highly controlled studies using careful objective biological measurements in studies on neural and hormonal mechanisms in aggression reduce the potential bias often present in studies that use self-report techniques. This suggests that research covered in this area has high internal validity
