Updating, shifting, and inhibition show both shared variance and separability in a foundational adult latent-variable study.

Executive function
Executive function is an umbrella for related higher-level processes involved in goal-directed regulation, commonly including updating working memory, shifting between tasks or rules, and inhibiting prepotent responses.
concept · seed
Scope
Includes
- multiple related cognitive processes
- measurement models and task demands
- everyday supports for planning, initiation, switching, memory, and inhibition
Excludes
- a single mental capacity
- a moral judgement about effort or character
- a direct one-to-one reading from a laboratory task to daily life
Claims
No single factor structure consistently fits executive-function measures across all ages and samples.
moderate confidenceUncertainties
Which factor models are valid across ages, cultures, neurotypes, and measurement methods?
Why it matters: A model can appear universal when it reflects a task set or sampled population.
What would reduce it:
- well-powered preregistered replications
- measurement-invariance analyses
- broader samples and multimethod measures
Status: open
How well do task scores predict person-defined functioning in real environments?
Why it matters: Laboratory performance may not identify barriers or effective accommodations.
What would reduce it:
- ecological momentary assessment
- real-world longitudinal outcomes
- participatory definitions of useful function
Status: open
Perspectives
cognitive researchers using latent-variable models
Executive functions are correlated but partly separable processes rather than one unitary faculty.
