Stress Testing
A computer RAM memory test works by writing patterns to every memory address to see if it holds. Brain training is similar - it's a stress test for your mind.
Finding Weak Spots
Diagnostic software identifies bad sectors. Similarly, memory quizzes can help you identify if you are weak in auditory or visual memory.
Optimization
After a RAM memory test identifies issues, you fix the hardware. After a brain test identifies weakness, you optimize your strategies (software) to compensate.
