Executive dysfunction, violence and aggression

Executive Functions (EFs) is an umbrella expression used for several processes and subprocesses encompassing goal-oriented behavior and decision-making strategies. However, the extent to which impaired EFs relate to and characterize different types of criminal behavior and aggressiveness is not clear. Similarly, research on the association between EFs and psychopathy has also produced mixed findings. The failure to disaggregate between different types of crime and antisocial individuals can impede the identification of specific neurocognitive mechanisms associated with crime. We reviewed the extent to which EFs (according to Miyake latent variable analysis) are associated with violent and non-violent crime, impulsive and premeditated aggression as well as psychopathic traits. Findings, although nonconsensual, suggest a more nuanced view on the association between EFs and crime, suggesting that different executive domains might be more compromised in violent and impulsive individuals, and specific psychopathy facets are more associated with executive dysfunction and criminality. Studies in line with this approach will allow offenders to benefit from intervention strategies that will address their specific deficits, optimizing their EFs and contributing to better cognitive management in demanding and complex situations, such as criminal and violent deterrence.Fundação para a Ciência e Tecnologia - FCT
