The data presented here would suggest that previous research that did not find a strong link between psychopathic traits and measures of inhibitory ability (Carlson & Thai, 2010; Kim & Jung, 2014) could have been the result of the relative simplicity of the inhibitory task. Here, the key experimental factor that impacts inhibitory performance is the requirement to flexibly adapt response behaviour in the light of changing context, therefore testing inhibitory functioning while executive functions are being utilised to a greater degree than is the case with the standard version of the Go/No-go task (Langenecker et al., 2007a). This is the first application of the PGNG paradigm to subclinical psychopathy and impulsivity and further investigation is required to ascertain the mechanism via which individual differences manifest. Additionally, future research should aim to replicate the current association between aspects of psychopathy and response inhibition deficits as measured by the PGNG in forensic samples to ascertain the here proposed link between psychopathy and inhibitory deficits.
