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://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:31927 P > 0.05). When the data were analysed according to disability, participants with moderate/severe disability showed significantly improved gross motor function following cathodal stimulation compared with sham (P=0.014). However, this was accompanied by decreased key grip strength in the unaffected hand (P=0.003). We are unable to endorse the use of anodal and cathodal tDCS in the management of upper limb dysfunction in chronic stroke patients. Although there appears to be more potential for the use of cathodal stimulation in patients with severe disability, the effects were small and must be considered with caution as they were accompanied by unanticipated effects in the unaffected upper limb.]]> Wed 24 Nov 2021 15:53:29 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36936 Wed 22 Jul 2020 09:33:14 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49449 Wed 17 May 2023 15:05:23 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43927 n = 157) and without (n = 79) asthma. Mothers with asthma participated in this study following participation in a randomized controlled trial of a novel asthma management strategy during pregnancy. Mothers completed the Parenting Stress Index Short Form during the first 12 months postpartum. Mothers with asthma also completed the Asthma Control Questionnaire. Results: Parenting stress did not differ between mothers with and without asthma. Additionally, for mothers with asthma, there were no differences in levels of parenting stress based on asthma control. Conclusions: This study suggests that mothers with asthma are not at an increased risk for excessive parenting stress. However, due to response and sampling bias, levels of parenting stress in asthmatic mothers may be underreported in our sample.]]> Wed 13 Mar 2024 08:01:44 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33111 Wed 11 Oct 2023 14:07:19 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:9435 Wed 11 Apr 2018 16:57:56 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:9436 Wed 11 Apr 2018 16:44:20 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:14484 Wed 11 Apr 2018 15:32:01 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:4635 CRs) and a centro-parietal late positivity (500-800 msec) with recollection (R Hits > K Hits, CRs). A long-term repetition effect was found for studied items judged "new" (Misses > CRs) in the same time window as the FN400, but with a posterior distribution. Finally, a centrally distributed masked priming effect was visible between 150 and 250 msec and continued into the 300-500 msec time window, where it was topographically dissociable from the FN400.

Further, theta oscillations across frontoparietal electrodes were also modulated by proactive control demands, with increased theta phase synchrony and power for cues signaling the need for goal updating. Finally, we present novel evidence of negative associations between behavioral variability and both power and phase synchrony across many of these frontoparietal electrodes that were associated with the need for goal updating. In particular, greater consistency in frontoparietal theta oscillations, indicated by increased theta phase and power during mixed-task blocks, resulted in more consistent task-switching performance. Together, these findings provide new insight into the temporal dynamics and functional relevance of theta oscillations during proactive cognitive control.]]> Wed 04 Sep 2019 09:39:54 AEST ]]>

Increased stroke risk also predicted performance on the cognitive screening test and the measure of executive functioning (all p < 0.002). Conclusions: Our findings indicate that cognitive impairment following a minor stroke or TIA may be attributed to the high prevalence of chronic vascular risk factors in these patients. This highlights the importance of long-term management of vascular risk factors beyond event recovery to reduce the risk of cognitive impairment. Increased stroke risk (i.e., ABCD2 score) was also associated with reduced cognition, suggesting that it may be helpful in signaling the need for further cognitive evaluation and intervention post-event.]]> Fri 20 May 2022 12:40:50 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53667 Fri 15 Dec 2023 11:06:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38215 50 years, n = 92). The latter were further subdivided into two subgroups with (CV+, n = 25) and without (CV−, n = 67) cardiovascular risk factors. Arterial pulsatility was measured using cardiac-gated phase-contrast flow quantification sequence and three indexes of whole-brain white matter microstructural organization [i.e., fractional anisotropy (FA), radial diffusivity (RaD), mean diffusivity (MD)] were derived from diffusion-weighted imaging (DWI). Cognitive ability was assessed using global cognitive functioning (MoCA) and a measure of working memory [sensitivity (d′) from a 2-back task]. Neither the whole group analysis nor the younger adult group showed an association between measures of arterial pulsatility, global white matter microstructural organization, and cognition. In older adults, higher MD and RaD were associated with increased arterial pulsatility and poorer working memory performance. The indirect pathway from arterial pulsatility to working memory performance via both MD and RaD measures was significant in this group. Interestingly, a comparison of CV+ and CV− subgroups showed that this mediating relationship was only evident in older adults with at least one CV risk factor. These findings are consistent with cardiovascular risk factors as underlying arterial, white matter, and cognitive decline in cognitively normal older adults.]]> Fri 13 Aug 2021 14:31:48 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:16734 Fri 09 Sep 2016 11:58:02 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54662 Fri 08 Mar 2024 10:56:51 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49838 Fri 02 Jun 2023 16:45:52 AEST ]]>
