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?

Self-control and impulsivity

Those who devalue future rewards more are likely to have less self-control and be more impulsive. Try the self-control or grit scale.

Other types of discounting

Discounting of future rewards is related to other kinds of discounting behavior. Try another discounting task now.

Time preferences

How much you devalue future rewards depends on your temporal or time preferences. Take the time preferences survey to find out more.

Devaluation or discounting summary

This area-under-curve (AUC) metric summarizes the results from the figure above as a single value. 1 implies no discounting at all, and 0 implies maximum discounting, where all future rewards are worthless.

Larger AUC values are associated with better self-control and life outcomes.
