Abstract

Different memory testing devices, systems, and methods for conducting memory tests, and for storing and displaying test data and trends are disclosed. The tests generally are based on generating a random sequence of signals, displaying the sequence to an examinee, the examinee memorizing the sequence, and inputting the sequence into the testing device. The signals could have visual, auditory, positional, and/or tactile components. The signals could also be alphanumeric strings.

The testing device measures test outcome variables, computes a composite memory score based on the test outcome variables, records and displays the stored test data. The testing device may also include a communication interface for periodically transferring the stored test data to a database residing on a remote server displaying the test data of the examinee on a website through an internet connection

The testing device need not be a physical device. Instead, it is possible to implement the functionality of the testing device in a virtual device which is basically a software application, installed and used on a personal computer, a mobile phone, a PDA, etc.
