Causal Prefrontal Contributions to Stop-Signal Task Performance in Humans

Journal of Cognitive Neuroscience, 2021
Abstract The frontal lobes have long been implicated in inhibitory control, but a full understanding of the underlying mechanisms remains elusive. The stop-signal task has been widely used to probe instructed response inhibition in cognitive neuroscience.

Preparation facilitates response inhibition based on a stop‐signal task

PsyCh Journal, 2023
AbstractThis study demonstrated that the higher stop‐signal probability condition showed a longer go reaction time and shorter stop‐signal reaction time (SSRT) compared with the lower stop‐signal probability condition. In addition, preparation cost was correlated with SSRT. These results suggest that preparation facilitates response inhibition.

Neural aftereffects of errors in a stop-signal task

Neuropsychologia, 2012
In order to maintain goal-directed behavior in a changing and distractive environment, one needs to continuously monitor one's own performance and adjust it in case of unfavorable outcomes. One aspect of behavioral adjustment commonly observed in reaction time tasks is an increase in response time in trials following an error, referred to as post-error

Sustained brain activation supporting stop‐signal task performance

European Journal of Neuroscience, 2014
AbstractStop‐signal paradigms operationalize a basic test of goal‐directed behaviour whereby an overarching stop goal that is performed intermittently must be maintained throughout ongoing performance of a reaction time go task (go goal). Previous studies of sustained brain activation during stop‐signal task performance in humans did not observe ...

Processing of Global and Selective Stop Signals

Experimental Psychology, 2010
This paper applied Donders’ subtraction method to examine the processing of global and selective stop signals in the stop-signal paradigm. Participants performed on three different versions of the stop task: a global task and two selective tasks. A global task required participants to inhibit their response to a go signal whenever a stop signal was ...

Applicability of the Stop-Signal Task for Preschoolers With ADHD

Perceptual and Motor Skills, 2016
Inhibitory deficits of children with attention deficit/hyperactivity disorder (ADHD) are well documented. However, the specific inhibition ability (stopping an ongoing response) of preschoolers with ADHD is little reported. This study adopted the tracking stop-signal task to examine preschoolers with ADHD.

Stop-signal task difficulty and the right inferior frontal gyrus

Behavioural Brain Research, 2013
The stop-signal paradigm is increasingly being used as a probe of response inhibition in basic and clinical neuroimaging research. The critical feature of this task is that a cued response is countermanded by a secondary 'stop-signal' stimulus offset from the first by a 'stop-signal delay'.

Evaluating Proactive Strategy in Patients With OCD During Stop Signal Task

Journal of the International Neuropsychological Society, 2018
AbstractObjectives: The aim of the present study was to investigate “Proactive-Adjustment hypothesis” (PA) during the Stop Signal Task (SST). The PA is implied in the highly inconsistent literature, and it deals with the role of response inhibition (RI) in obsessive-compulsive disorder (OCD).

Suppression of human cortico-motoneuronal excitability during the Stop-signal task

Clinical Neurophysiology, 2009
To investigate whether motor suppression is an active process, and to clarify its somatotopic organization, we investigated cortico-motoneuronal excitability using transcranial magnetic stimulation (TMS) during the Stop-signal task.Subjects were asked to press a button following a Go cue; a Stop-signal followed the Go cue by a certain time delay in 25%

Assessing inhibitory control: A revised approach to the stop signal task

Journal of Attention Disorders, 2003
The stop signal task (stop task) is designed to assess inhibitory control and is a frequently used research tool in clinical disorders such as ADHD and schizophrenia. Previous methods of setting stop signal delay and of assessing inhibitory control are problematic.
