Removing learning effect from cognitive tests
A system for removing the learning effects from cognitive tests includes variation of the difficulty of the test between the administering of the tests so as to minimize the ability of a test taker to memorize a test.
1 . A system for removing learning effects from repeated cognitive tests, comprising:
a unit for administering a cognitive test in which an opto-cognitive test modality is employed and,
varying the test administered to a test taking individual between tests so as to prevent the individual from memorizing the test.
2 . The system of claim 1 , wherein said opto-cognitive test modality includes a smooth pursuit test.
3 . The system of claim 2 , wherein said smooth pursuit test includes presenting an on-screen target having at least one target characteristic and moving said target along a smooth pursuit path.
4 . The system of claim 3 , wherein the variation of said cognitive test includes variation of said smooth pursuit path.
5 . The system of claim 3 , wherein the variation of said cognitive test includes variation of target characteristics.
6 . The system of claim 3 , wherein the variation of said smooth pursuit path or said target characteristic between each test includes control of said path and said target characteristic to avoid excessive difficulty.
7 . The system of claim 2 , wherein the said smooth pursuit test includes an on-screen target having a predetermined characteristic traveling along a smooth pursuit path and wherein variation of said test includes variation of said smooth pursuit path or target characteristic that duplicates the difficulty of the test prior to variation.
8 . The system of claim 7 , wherein said test variation includes change of direction of target movement.
9 . The system of claim 7 , wherein test variation includes rotation of path orientation.
10 . The system of claim 7 , wherein said test variation includes variation of path complexity.
11 . The system of claim 7 , wherein said test variation includes variation of target movement including one of speed and acceleration.
12 . The system of claim 7 , wherein said test variation includes change of overall path type.
13 . The system of claim 7 , wherein the metric measured by said smooth pursuit test includes one of anticipatory timing, variability, regularity and peak performance.
14 . A method for removing learning effects from repeated cognitive tests, comprising the step of varying the test administered to a test taking individual between tests so as to prevent the individual from memorizing the test.
15 . The method of claim 14 , wherein the cognitive tests include an opto-cognitive test.
16 . The method of claim 15 , wherein the opto-cognitive test includes a smooth pursuit test.
17 . The method of claim 16 , wherein the smooth pursuit test includes presenting an on-screen target having at least one target characteristic and moving the target along a smooth pursuit path.
18 . The method of claim 17 , wherein the variation of the smooth pursuit test includes variation of the smooth path.
19 . The method of claim 17 , wherein variation of the smooth pursuit test includes variation of target characteristics.
20 . The method of claim 17 , wherein the smooth pursuit test variation test includes control of the path and the target characteristics to avoid excessive difficulty.
21 . The method of claim 17 , wherein the smooth pursuit test variation includes change of direction of target movement.
22 . The method of claim 17 , wherein the smooth pursuit test variation includes rotation of path orientation.
23 . The method of claim 17 , wherein the smooth pursuit test variation includes variation of path complexity.
24 . The method of claim 17 , wherein the metric utilized for measuring cognitive performance in the smooth pursuit test includes one of anticipatory timing, variability, regularity and peak performance.
25 . Apparatus for removing learning effects from repeated cognitive tests comprising:
an opto-cognitive test unit in which the test administered to a test taking individual is varied between tests so as to prevent the individual from memorizing the test.
26 . The system of claim 25 , wherein said octo-cognitive test unit includes a screen for presenting a target moving along a smooth pursuit path.
27 . The system of claim 26 , wherein said screen is part of a tablet.
28 . The system of claim 26 , wherein said screen is carried in a desktop unit.
29 . The system of claim 26 , wherein said screen is carried by a helmet worn by the test taking individual.
