The control of deliberate waiting strategies in a stop-signal task [PDF]
Brazilian Journal of Medical and Biological Research, 2004 To inhibit an ongoing flow of thoughts or actions has been largely considered to be a crucial executive function, and the stop-signal paradigm makes inhibitory control measurable.

Motor Preparation Disrupts Proactive Control in the Stop Signal Task [PDF]
Frontiers in Human Neuroscience, 2018 In a study of the stop signal task (SST) we employed Bayesian modeling to compute the estimated likelihood of stop signal or P(Stop) trial by trial and identified regional processes of conflict anticipation and response slowing.

Mouse movement measures enhance the stop-signal task in adult ADHD assessment. [PDF]
PLoS ONE, 2019 The accurate detection of attention-deficit/hyperactivity disorder (ADHD) symptoms, such as inattentiveness and behavioral disinhibition, is crucial for delivering timely assistance and treatment.

A reaction-time adjusted PSI method for estimating performance in the stop-signal task. [PDF]
PLoS ONE, 2018 A central experimental task in executive control research is the Stop-signal task, which allows measuring the ability to inhibit dominant responses. A crucial aspect of this task consists of varying the delay between the Go- and Stop-signal.

Dissociating Two Stages of Preparation in the Stop Signal Task Using fMRI. [PDF]
PLoS ONE, 2015 Often we must balance being prepared to act quickly with being prepared to suddenly stop. The stop signal task (SST) is widely used to study inhibitory control, and provides a measure of the speed of the stop process that is robust to changes in subjects'

A cognitive process modeling framework for the ABCD study stop-signal task. [PDF]
Dev Cogn Neurosci, 2023 The Adolescent Brain Cognitive Development (ABCD) Study is a longitudinal neuroimaging study of unprecedented scale that is in the process of following over 11,000 youth from middle childhood though age 20. However, a design feature of the study's stop-signal task violates "context independence", an assumption critical to current non-parametric methods

Effects of NMDA Receptor Hypofunction on Inhibitory Control in a Two-Layer Neural Circuit Model
Mathematics, 2023 Inhibitory control plays an important role in controlling behaviors, and its impairment is a characteristic feature of schizophrenia. Such inhibitory control has been examined through the the stop-signal task, wherein participants are asked to suppress a

SimSST: An R Statistical Software Package to Simulate Stop Signal Task Data
Mathematics, 2023 The stop signal task (SST) paradigm with its original roots in 1948 has been proposed to study humans’ response inhibition. Several statistical software codes have been designed by researchers to simulate SST data in order to study various theories of ...

The Difficulty in Numerical Computation Impacts Motor Decisions in a Stop-Signal Task. [PDF]
Eur J NeurosciABSTRACT The proper interpretation of environmental information is necessary for effective decision-making. The resulting cognitive burden may affect the entire process if interpretation is not instantaneous. In this study, we investigated how numerical distance (ND), a measure of cognitive demand in numerical comparisons, influences ...

Event-related potentials during contralateral switching over motor programs in humans
Regulatory Mechanisms in Biosystems, 2020 The study of processes related to the motor response suppression and the evaluation of the next, alternative, response after termination of the already observed initial motor response is of significant interest to modern scientists.
