OBJECTIVE: Regarding the impairments in decision-making strategies as a predisposing factor to adverse behaviours and sexual violence, we hypothesize impairments on decision-making processes in Child Sexual Offenders (CSO) population. The aim of this study was to highlight these alterations and characterize them.
METHODS: We compared decision-making processes between sixty-four convicted CSO and sixty-four matched subjects without criminal history, using the Iowa Gambling Task (IGT). A Bayesian computational model (ORL) was applied to assess different components of decision-making: reward learning, punishment learning, forgetfulness, win perseverance and deck perseverance.
RESULTS: Respecting the underlying processes of the IGT task, the ORL model revealed that reward learning (95% HDI [-0.299, - 0.099]) and punishment learning were lower in CSO compared to controls (95% HDI [-0.054, - 0.021]), while forgetfulness (95% HDI [0.168, 0.877]) and deck perseverance (95% HDI [0.659, 4.478]) were higher.
CONCLUSIONS: CSO display impairments in decision-making strategies in learning processes related to reward or punishment, and seem less prone to make long-term strategies with a strong preference toward perseverance. These findings have important potential applications for future research on sexual violence, management of CSOs cognitive vulnerabilities and adjusting strategies to reduce the risk of recidivism.
