Structural equation model of the predictive paths between the latent externalizing disorders factor and the significant P3 simple effect from the primary analysis (low load, incentive, infrequent trial type). Path coefficients are standardized beta weights and are all significant at p< .05, except for the relationship between Constraint (reverse scored) and the EXT latent trait. AAB=Adult antisocial behavior, CD=Conduct Disorder, Alc=AUDIT, Drug=DUDIT, CON (rev)= MPQ-BF Constraint reverse scored, EXT=externalizing latent trait, P3=low load, incentive, infrequent trial type.
