A neurocognitive task designed to provide a sensitive measure of the time taken by the brain to inhibit or suppress inappropriate motor responses. The stop-signal paradigm was originally developed by Gordon Logan in the 1980s, based on a cognitive task first used by Lappin and Erikson in 1966.
The stop-signal paradigm is a useful tool for the investigation of response inhibition. In this paradigm, subjects are instructed to respond as fast as possible to a stimulus unless a stop signal is presented after a variable delay. However, programming the stop-signal task is typically considered t …
Task format. The participant must respond to an arrow stimulus, by selecting one of two options, depending on the direction in which the arrow points. The Stop-Signal Task is designed to measure motor response inhibition, one aspect of cognitive control. On each trial of this task participants are instructed to make a speeded response to an imperative "go" stimulus except on a subset of trials when an additional "stop signal" occurs, in which case participants are instructed that they should make no response.
Consists of a go component (e.g. a two-choice discrimination task) and a stop component (suppressing the response when an extra signal appears). Stop-signal reaction time task, stop-signal paradigm, countermanding task: Go trial ERP components associated with successful and unsuccessful stopping in a stop-signal task. 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 Frederick Verbruggen changed the title from STOP-IT: software for the stop-signal paradigm to software for the stop-signal paradigm 2019-02-21 06:05 PM Frederick Verbruggen created a link to project Capturing the ability to inhibit actions and impulsive behaviors: A consensus guide to the stop-signal task 2014-07-03 · One of the most prevalent measures of inhibitory control in the stop-signal task is the SSRT. The SSRT is an estimate of stopping or inhibition speed and is derived by subtracting from a measure of “go” RT, a measure of the stop-signal delay (SSD)–the stimulus-onset asynchrony between “go” and “stop” stimuli.
We employed a simple reaction time (RT) task in this stop signal paradigm, as described in detail in our previ-ous studies [Li et al., 2006, 2008b, 2009b]. Briefly, there were two trial types, ‘‘go’’ and ‘‘stop,’’ randomly inter-mixed.

However, programming the stop-signal task is typically considered t … The stop-signal task is an essential tool to determine how quickly response inhibition is implemented. Despite its apparent simplicity, there are many features (ranging from task design to data analysis) that vary across studies in ways that can easily compromise the validity of the obtained results. The Stop Signal Task is best described as a laboratory measure of inhibitory control.

The stop signal task consisted of the same stimuli as in the calibration stage (black right or left arrows as the go signals and a blue square as the stop signal). However, instead of using a staircase, the SSD was fixed to the critical delay calculated from the calibration phase, which represented a 66% chance of stopping for each participant. signal task (Logan et al. 1984). The stop-signal task is considered the primary measure used in clinic- and laboratory-based research to investigate behavioral inhibi-tion in children with ADHD, due to its unique ability to capture theoretically important cognitive processes by means of the stop-signal reaction time (SSRT) metric. The
Typically, the go/no-go task (GNGT) or the stop signal task (SST) are used interchangeably to capture individual differences in response inhibition. On the one hand, factor analytic and conjunction neuroimaging studies support the association of both tasks with a single inhibition construct.

doi: 10.3389/fpsyt.2019.00765 Stop-signal task (SST) has been a key paradigm for probing human brain mechanisms underlying response inhibition, and the inhibition observed in SST is now considered to largely depend on a fronto basal ganglia network consisting mainly of right inferior frontal cortex, pre-supplementary motor area (pre-SMA), and basal ganglia, including subthalamic nucleus, striatum (STR), and globus pallidus The stop signal task (SST; Logan, Cowan, & Davis, 1984) puts a much higher load on inhibitory control as it requires the sudden cancellation of an already initiated motor response, whenever a stop signal is presented shortly after a go signal. Implementation of a Stop Signal Test.
