Several methods are used to better define and optimize item sets for short-term memory tests with respect to chunkiness and homogeneity, including dynamically changing the test item set to make it have as few chunkable items as possible. A resulting item set allows the test taker to see in an intuitive way how her or his memory has a limited capacity of, typically, three non-chunkable items. The test can be done, inter alia, via computer, via the telephone, and via robocalling. It can, inter alia, provide mass screening for Alzheimer's disease and detect early Alzheimer's disease in drug trials. |

1. A method for testing the brain activity of a test taker, comprising:
(a) providing a system selected from the group consisting of a single computational device and multiple computational devices, said system having input, output, and storage mechanisms, (b) selecting an item set that has a property selected from the group consisting of high homogeneity, low homogeneity, high chunkiness, and low chunkiness, (c) using said system to store said item set, (d) presenting a subset of items from said item set to said test taker, (e) storing said subset of items, (f) requesting said test taker to respond with a response selected from the group consisting of recalling said subset of items and recognizing said subset of items, (g) storing said response and timings of said response, (h) repeating steps (d)-(g) N times where N is selected from the group consisting of no times, one time, two times, and several times, whereby said test taker is tested with an item set with said property. |
