There isn’t a single kid out there who doesn’t love to gobble up a delicious cookie. But what if their patience and ability to not eat a cookie could predict how they’ll do in the SATs years later?
In the video below, John Medina, author of Brain Rules for Baby, discusses “The Cookie Test,” a study done by Walter Mischel in the Stanford Lab in the late 1960s. The study focused on impulse control — give a young child one cookie, but offer two if he/she is able to hold off eating it for ten minutes. Naturally, some young children won’t be able to resist, while others are able to rationalize the decision to abstain from the cookie.
This is part of a suite of behaviors called executive function, which controls a child’s ability to filter information. This includes planning, foresight, problem solving, and goal setting, and engages a form of short-term memory called working memory.
In Medina’s article on the subject, he references how executive function is “actually a better predictor of academic success than I.Q.” In fact, it’s a signficant difference: “Children who could delay gratification for 15 minutes scored 210 points higher on their SATs than children who lasted one minute.” It’s an astoundingly simple way to determine if these are skills a child might need to improve.
We can also provide specific brain exercises and games you can do with your child to improve their cognitive ability.

Key takeaways
- The "Cookie Test" can identify a child's impulse control.
- These tests can determine a child's executive function controls the ability to filter information.
- Checking executive function is a better predictor of academic success than I.Q.
Is your child struggling in school?
Get your free personalized learning roadmap
You describe what you see at home. We turn it into a plan you start this week.
- Answer 5 short questionnaires about what you already notice, 30–45 minutes at your own kitchen table
- Your child sits no test and gets no score: nothing to schedule, nothing for them to dread
- You do the answering, the AI does the writing, and a person reviews it before it reaches you
- Access all 40+ courses instantly: reading, math, focus, processing and more, with new ones added regularly
Why we use AI, plainly: it writes from a knowledge base our team maintains and audits. We work through it line by line and pull anything the evidence stops supporting. The roadmap you get on Tuesday reflects what we corrected on Monday, and a human still reads it before you do.
Your school district must evaluate your child free of charge if you ask in writing, whatever your income and whatever the outcome (US, 34 CFR 300.111 and 300.301(b)). That route takes time and answers a different question than you do. This one starts today, from what you already know.
Your answers stay yours. We do not sell your personal information, and we do not hand identifiable assessment data to outside AI companies to train their models.
A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
