Null Hypothesis (H_1): There is a no correlation between males that have committed a murder and them having a traumatic brain injury (TBI).
There was previous research done on the possible relationship between head injury and criminal activity. One study relied on the self-reports of head injuries, cognitive functioning problems, and emotional difficulties with offenders and non-offenders. The other study reproduced the general features of the first study with a larger sample of offenders and non-offenders to assess the replicability of Study 1 (Sarapata, Herrmann, Johnson, & Aycock, 1998). The third study asked head-injured offenders to report dates of their head injury and initial criminal acts. The results of this last study will be seen to aid in the interpretation of the results of the two first studies (Sarapata, Herrmann, Johnson, & Aycock, 1998). Though the study had limitations as it relies on self-reports which can sometimes not be entirely …show more content…
As stated before correlation does not mean causation so a higher pool of individuals from other counties besides the United States should be used. Further studies could focus on of neurodevelopmental problems that can be caused by head injury and their complex interaction with other psychosocial factors that produce these varying adverse outcomes. Also, a consideration of birth defects or drug use that cause violent behavior that could possibly that could lead to murder. Further research could be done on redhibition for individuals who have a TBI to reduce the possible of the committing murder or crime. As some of the changes seen are behavior which could be altered. Also, would be better to have international collaborative research efforts in using the innovative techniques borrowed from the study of rare
