This is an example of what you can expect at the beginning and at the end of your session.

You'll be shown a random number of blue and yellow circles for a short period of time, about 0.6 seconds. Indicate which color had more by pressing "b" or "y."

This demo is based on an experiment designed by researchers at Johns Hopkins University and the Kennedy Krieger Institute. You cannot modify certain parameters, such as age, as you can in the actual test. This may affect the accuracy of your results.

Remember, this information is confidential. We don't want potential participants to know why we're doing this test until they've done it, because their results could be affected. So invite anyone who may be interested, but don't say a word about what we're looking for.

## So what's the point of doing this experiment?

We want to see how individuals vary in their approximate number sense. Research has shown that this understanding may be related to how well you perform in math while in school.

## What is Approximate Number Sense?

The approximate number system is what allows you judge relative quantities based on what you see. It does not, however, extract exact amount. Although this is possible, you wouldn't look at a group of thirty five circles and say that there's thirty five. However, ANS would let you see that a group of ten circles is bigger than a group of two.

## What do my results mean?

While we hope that you find the results interesting, keep in mind some limitations when viewing your feedback. For one, this is only a demo. In the actual test, you can customize the program so that it calibrates to different parameters, such as age.

Furthermore, these kinds of results only count when we get many, many results and calculate an average. Even then, the average doesn't necessarily apply to you.

Don't fret if your results are surprising. There are a lot of reasons why you might not have done as well as you expected, such as being distracted or a slow Internet connection.

If you have any questions, comments, or concerns, please email us. Your score was 90% correct. Based on the results we have so far, the average person who takes this test scores 90% correct.

Your percentile score on this test was 50, meaning you scored higher than 50% of the people who took this test.

It took you an average of 0.35 seconds to respond to each item. The average person takes about 1 second(s). That means you responded to each item a little more quickly than the average person who takes this test.
