Nineteen publications were included in the Stroop meta‐analysis and literature review. All studies used a traditional color–word Stroop task in normal volunteers. All reported response locations in stereotactic coordinates. Studies differed in their control conditions and response modality (manual or verbal). The average number of subjects (n) in each study was 13.1 with a standard deviation of 6.4.
