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

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.

Further Manipulation of the Stop-Signal Task: Developmental Changes in the Ability to Inhibit Responding With Longer Stop-Signal Delays

International Journal of Neuroscience, 2001
The stop-signal task, a measure of inhibitory control, was further modified in order to examine its suitability as a task for very young children. A previous study (Carver et al., 2001) showed that it can be successfully adapted for use with primary school-aged children. The present study manipulated the presentation of the signal to inhibit responding

Living on the edge: strategic and instructed slowing in the stop signal task

Psychological Research, 2012
The stop signal task is widely adopted to assess motor inhibition performance in both clinical and non-clinical populations. Several recent studies explored the influence of strategic approaches to the task. In particular, response slowing seems to be a strategic approach commonly adopted to perform the task.

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.

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 ...

The effect of noradrenergic attenuation by clonidine on inhibition in the stop signal task

Pharmacology Biochemistry and Behavior, 2013
Understanding the neuropharmacology of inhibition is of importance to fuel optimal treatment for disorders such as Attention Deficit/Hyperactivity Disorder. The aim of the present study was to assess the effect of noradrenergic antagonism by clonidine on behavioral-performance and brain-activity indices of inhibition. A placebo-controlled, double-blind,

Development of response activation and inhibition in a selective stop-signal task

Biological Psychology, 2014
To gain more insight into the development of action control, the current brain potential study examined response selection, activation, and selective inhibition during choice- and stop-signal processing in three age groups (8-, 12-, and 21-year-olds). Results revealed that age groups differed in the implementation of proactive control; children slowed ...

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%

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

Psychophysiology, 2003
Abstract The 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
