Cognitive Abilities in the Wild: Population-scale game-based cognitive assessment

Psychology and the social sciences are undergoing a revolution: It has become increasingly clear that traditional lab-based experiments are challenged in capturing the full range of individual differences in cognitive abilities and behaviors across the general population. Some progress has been made toward devising measures that can be applied at scale across individuals and populations. What has been missing is a broad battery of validated tasks that can be easily deployed, used across different age ranges and social backgrounds, and in practical, clinical, and research contexts. Here, we present Skill Lab, a game-based approach affording efficient assessment of a suite of cognitive abilities. Skill Lab has been validated outside the lab in a crowdsourced broad and diverse sample, recruited in collaboration with the Danish Broadcast Company (Danmarks Radio, DR). Our game-based measures are five times faster to complete than the equivalent traditional measures and replicate previous findings on the decline of cognitive abilities with age in a large cross-sectional population sample. Finally, we provide a large open-access dataset that enables continued improvements on our work.
