Attention & cognitive control


The Stroop task measures how well you can control your attention and inhibit information and responses that are unrelated to your goals.

This task is often used to study cognitive control, executive control, or executive function. These processes support flexible, adaptive responses, and complex goal-directed behavior and thought.

Longer delays increase devaluation

Assume you'll receive $1 the future—this value is the maximum value on the y-axis. This boxplot suggests that the more days you have to wait before you receive $1, the more you devalue or discount that $1. The longer you have to wait, the more its subjective value drops.

What do these results mean?

Discounting across the globe

People in different countries and cultures differ in how much they care about or devalue future rewards. Brighter regions indicate less discounting or impulsivity.
