Using a stop-signal paradigm with a number parity go task, we implemented a novel hierarchical Bayesian model of response inhibition that estimates stop-signal reaction time (SSRT) as a distribution and also accounts for failures to react to the stop-signal (i.e., “trigger failure”), and failure to react to the choice stimulus (i.e., “go failure” or omission errors). In line with previous studies, the model reduced estimates of SSRT by approximately 100 ms compared with traditional non-parametric SSRT estimation techniques. We found significant relationships between behavioural and self-report measures of impulsivity and traditionally estimated SSRT, that did not hold for the model-based SSRT estimates. Instead, behavioural impulsivity measures were correlated with rate of trigger failure. The relationship between trigger failure and impulsivity suggests that the former may index a higher order inhibition process, whereas SSRT may index a more automatic inhibition process. We suggest that the existence of distinct response inhibition processes that may be associated with different levels of cognitive control.]]> Wed 25 Jan 2023 11:37:35 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55188 Wed 24 Apr 2024 12:59:56 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47074 Tue 13 Dec 2022 16:21:23 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40235 Thu 07 Jul 2022 10:59:44 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35143 Fri 31 Jan 2020 15:47:10 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36996 Fri 30 Jun 2023 08:59:22 AEST ]]>
