What lab-based and self-report executive function measures predict in real-world task performance

Area of Science:

• Cognitive Psychology
• Neuroscience
• Psychometrics

Background:

• Executive functions (EF) are crucial for goal-directed behavior.
• Assessing EF in real-world contexts presents challenges.
• Discrepancies exist between laboratory and self-report measures of EF.

Purpose of the Study:

• To compare the predictive validity of laboratory cognitive tests versus self-report inventories for real-world executive function tasks.
• To determine which assessment method better predicts performance in an ecologically valid setting.

Main Methods:

• Seventy-one university students completed cognitive tasks, self-report questionnaires, and an ecologically valid Library task.
• The Library task incorporated behavioral and eye-tracking measures.
• Regression analyses were used to assess predictive validity.

Main Results:

• Laboratory EF measures predicted task accuracy and specific eye-tracking behaviors (e.g., fixation during instruction reading).
• Self-report EF measures were associated with global eye-movement metrics (e.g., fixation count and rate).
• Effect sizes were modest, and neither method broadly predicted all outcomes.

Conclusions:

• Laboratory tests and self-report inventories capture distinct aspects of executive functioning.
• Assessment methods should be chosen based on theoretically motivated real-world outcomes.
• A complementary approach to EF assessment is supported.
