Separating Within-trial Activities in the Stop Signal Task Using fMRI
… rapidly unfolding within-trial activities in a stop signal task using fMRI. Current models of inhibitory control address processes that are engaged after the presentation of go- and stop-signals. The first study presented here separated warning- from response-phase activities in healthy adults …

Re-Examining the Stop-Signal Task to Test Competing Theories of AD/HD
… by conducting fine-grained analyses of the Stop-Signal Task and another putative measure of behavioral inhibition, the Gordon Continuous Performance Test (G-CPT), in a large sample of children and adolescents. The inhibition theory posits that performance on these tasks reflects increased …

READY, STEADY, AND GO. A Transcranial Magnetic Stimulation Study of Set-Related Inhibitory Activity in the Human Dorsal Precentral Region
… planned movements when appropriate, but also to stop them if required. Action initiation and control are characteristic features of many of our daily life actions. There is a large amount of evidence in monkeys and humans suggesting that the dorsal premotor cortex (PMD) and the supplementary …

Arousal theory and the interrelationships of caffeine, nicotine and impulsivity
… Participants engaged in three behavioral tasks: the Stop Signal Task (SST), the Stroop Color-Word Test (SCWT), and the Delay Discounting Task (DDT). Drug intake did not produce significant changes across conditions on any of the three tasks. The hypothesis that caffeine and nicotine have …

The Influence of Media Violence on the Neural Correlates of Empathic Emotional Response
… were examined while participants completed a stop-signal task using emotional faces. At baseline, gamers and nongamers performed equally well at a gender discrimination task and at inhibiting behavior, but gamers had significant reductions in their ACC generated N200 component, reflective of …

Hedonia and Eudaimonia: Associations with Academic Success, Wellbeing, and Neuropsychological Functioning
… Stroop Color-Word test, Wisconsin Card Sorting Task, and a Stop Signal task) and “hot” executive functioning (Iowa Gambling Task, Temporal Discounting Task). Semester GPA was collected from school records. Eudaimonia was significantly positively associated with GPA. Eudaimonia was also …

High-Definition Fiber Tracking Study of the Executive Control Network in Blast-Related Traumatic Brain Injury
… neuropsychological evaluation that included the Stop Signal Task (SST) and structural magnetic resonance imaging. HDFT was used to derive quantitative metrics of tracts between the dorsolateral prefrontal cortex (DLFPC) and the putamen, caudate, and thalamus. Groups had similar demographic …

Electroencephalographic and Cognitive Underpinnings of Inhibitory Control in Obsessive-Compulsive Disorder: From Actions to Thoughts
… ability to control actions as measured by the Stop-Signal/Go No-Go task; (ii) They also present deficits in attentional set-shifting in an extra-dimensional set-shifting task; (iii) OCD is marked by difficulties in the ability to control thoughts, as demonstrated by a Retrieval-Induced …

Examining the Relationship Between Impulsive Personalities and Neural Functioning in Cocaine-Addicted Participants
… of Adult Reading (WTAR). They then performed the stop signal task (SST) during functional magnetic resonance imaging (fMRI) to gather data on neural activation during Stop-Success (SS) and Stop-Failure (SF). fMRI data was analyzed using FSL imaging software. All statistics were run with SPSS …
