Biological protective factors for antisocial and criminal behavior

Purpose

Although risk factors are typically the focus of criminological research, increasingly researchers are interested in identifying protective factors that reduce the probability of antisocial behavior, either in the presence or absence of risk factors. Biosocial researchers are in an opportune position to research factors that protect against the development of antisocial behavior in high-risk individuals, given biosocial criminology’s focus on the interaction between biological and social factors. The purpose of this article is to review neuropsychological and psychophysiology research into protective factors.

Results

Of the neuropsychological factors, high IQ has the best-replicated protective effects, though executive functioning is also a promising candidate as a protective factor. High resting heart rate, as well as enhanced autonomic fear conditioning and attentional processing may also have protective effects.

Conclusions

Though research into biological protective factors is currently limited, there is promising evidence that biological factors could help us to better understand why some individuals do not become antisocial or criminal in the presence of high social risk. Neuropsychological and psychophysiological measures are relatively easier and less costly to operationalize than other biological measures, making them promising candidates for criminological researchers who would like to incorporate biological measures into their research designs.
