This might be of interest to you; I’ve built this really fun little brain testing application for a science project for my course.
It tests for reaction time, and memory(more precisely backward digit span) It only takes a few minutes to complete, and at the end you are given your ‘percentile’, that is how well you have done compared to others.
Its available from here:
- it would really help out if some of you could do it. You could post your percentiles and results on this thread!
