The process to encode, retain and retrieve information is known as memory. Ever since models for short-term memory and working memory systems were proposed, the function and importance of the short-term memory and working memory systems have been explored by a number of studies which in part have examined factors which may affect memory capacity. Although there are many undetermined factors which may affect the result of these two different memory span test, recent studies have suggested a link between human mental condition and memory capacity. These studies show that the results of simple memory span tests are improved when subjects are in a state of focus. These results suggest a correlation between the attention level in a state of focus and the result of memory span test. The current study employed the NeuroSky MindWave headset to monitor and record the mental state of subjects while performing simple and complex memory span tests to understand the correlation between test results and the headset’s measurements. This correlation is then used to design an application on Android Plate to provide an estimate of the memory ability of a subject while performing memory span tests.
