Executive Function
Executive Function (EF) refers to high-level control: planning, inhibition, set-shifting, working memory. The concept is central to modern cognitive psychology and psychometrics — particularly to how IQ is theorized, measured, and interpreted.
What executive function actually means
→Pause. Find out YOUR IQ before you keep reading.In cognitive psychology, executive function is operationalized as high-level control: planning, inhibition, set-shifting, working memory. It is distinct from related constructs in that it specifically captures a distinct, measurable aspect of cognitive function.
How it's measured
→Curious how YOU score? 20-min calibrated test.Measured through standardized testing batteries and laboratory paradigms specific to the construct.
Relationship to IQ
→The numbers above? Find out where YOU land.Executive Function is integrated into the broader theory of IQ and cognitive function. It contributes to and is partially measured by composite IQ scores.
Why this matters
→Knowing about IQ ≠ knowing yours. Take the test.Understanding executive function is foundational for anyone trying to interpret an IQ score meaningfully. The single composite IQ number conceals significant variation across cognitive functions; understanding the components is how you go from "I scored 130" to "I scored 130, with particular strength in [X] and relative weakness in [Y]."

Executive Function (EF) refers to high-level control: planning, inhibition, set-shifting, working memory. It is a central concept in cognitive psychology and IQ measurement.
How is executive function different from general IQ?
Composite IQ is a weighted aggregate of multiple cognitive abilities. Executive Function is one specific component or property that contributes to but is not identical to the IQ score.
Can executive function be improved?
Generally limited room for improvement in trait-level cognitive properties; significant variability in measured performance day-to-day.
