During tasks requiring response inhibition, intra-individual response time variability, a measure of motor response preparation, has been found to correlate with errors of commission, such that individuals with higher variability show increased commission errors. This study used fMRI to examine the neural correlates of response variability in 30 typically developing children, ages 8-12, using a simplified Go/No-go task with minimal cognitive demands. Lower variability was associated with Go… CONTINUE READING
