There was a highly significant main effect of phase, F (1, 52) = 51.64, p <.001, η p 2 = .50, indicating that participants committed more errors during the reversal phase ( M = 10.6, SD = 6.9) than the acquisition phase ( M = 2.9, SD = 2.7) ( Figure 1 ).
On the CGT, the two groups of offenders, as compared to the non-offenders, also displayed poorer quality of decision-making despite increased deliberation times and a strong trend for less modulation of their betting as the probability of loss increased, but similar levels of impulsivity and risk-taking.
The offenders with ASPD+P showed a trend in the same direction.
