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 ...

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

ERP components associated with successful and unsuccessful stopping in a stop‐signal task

Psychophysiology, 2003
AbstractThe primary aim of this study was to examine how response inhibition is reflected in components of the event‐related potential (ERP), using the stop‐signal paradigm as a tool to manipulate response inhibition processes. Stop signals elicited a sequence of N2/P3 components that partly overlapped with ERP components elicited by the reaction ...

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'.

Repetition priming in the stop signal task: The electrophysiology of sequential effects of stopping

Neuropsychologia, 2012
Inhibition of a response affects the processing of subsequent stimuli. When a response has to be made to a stimulus to which a response was previously inhibited, response time increases. In this study, we investigated the neurophysiological underpinnings of this repetition priming phenomenon.

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).

Brain networks subserving fixed versus performance-adjusted delay stop trials in a stop signal task

Behavioural Brain Research, 2012
The stop signal task is a widely used tool for assessing inhibitory motor control. Two main task variants exist: (1) a fixed delay version, where all volunteers complete the same trials, resulting in performance differences due to individual variation in inhibitory capacity, and (2) a performance-adjusted version that uses a tracking algorithm to ...

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%
