Human cognition benchmark · Cognitive control
Executive Function (Stroop, Trail Making, Wisconsin Card Sorting)
Short name: Executive Function · Introduced 1935 · Stroop, Reitan, Berg
Tasks isolating inhibition, set-shifting, and monitoring - the brain's cognitive control suite.
What it measures
Top-down regulation of attention and behavior, supported primarily by the prefrontal cortex.
Format
Stroop (name ink color while ignoring conflicting word), Trail Making A/B (connect numbers, then alternate numbers and letters), Wisconsin Card Sorting (infer and adapt to changing rules).
Scoring
Reaction-time interference (Stroop), time and errors (Trails), perseverative errors (WCST). Age- and education-normed.
Notable results
- Differentiates ADHD, frontal lobe damage, and early dementia.
- Perseverative errors localize to dorsolateral prefrontal dysfunction.
- Executive function predicts academic and life outcomes independently of IQ.
Strengths
- Well-validated clinical sensitivity.
- Maps onto distinct prefrontal subregions.
Limitations
- Task impurity - each measure captures multiple processes.
- Strong practice effects.
