Cognitive Dysfunction and Criminal Behavior: Investigating Executive Functions in Convicted Individuals

Background: Studies on the association between cognitive dysfunction and criminality have shown that individuals in prison, particularly repeat offenders and those convicted of violent crimes, tend to exhibit difficulties in cognitive, social, and emotional functioning. The objective of this study was to evaluate and characterize cognitive and executive functioning of incarcerated individuals, while also seeking to understand the impact of incarceration on executive functions. Methods: The sample consisted of 30 participants at various stages of their sentences. Neuropsychological assessments were conducted using cognitive screening tests and tests directed to assess executive functions and decision making. Results: Neurocognitive performance was within normative ranges. Selective associations between sentence duration and specific executive functions were observed, suggesting a relationship with criminal severity indicators. Decision-making also appeared impaired, as no evidence of learning was found and deck selection focused on more disadvantageous decks. Conclusions: These findings a relationship between indicators of criminal severity and specific aspects of executive functioning and decision making, rather than a generalized cognitive impairment. However, these conclusions require further research under this topic in larger and more diverse samples.
