Abstract

A time perception test instrument for performing a self-administered time perception test by a test subject, including a plurality of individual flashing lights arranged in an array and with all of the lights except one flashing intermittently at regular intervals and with one of the lights flashing at irregular intervals and with a plurality of test buttons corresponding in number to the flashing lights and with one test button associated with each flashing light to allow the test subject to select any individual one of the flashing lights judged by the test subject to be the light flashing at irregular intervals and with a random selector for randomly selecting one of the plurality of lights to flash at irregular intervals after each selection by the test subject. A coincidence detector produces a coincidence signal when the test subject selects a particular one of the flashing lights which is flashing at irregular intervals.

Dependent claims

Apparatus for performing a self-administered time perception test by a test subject, including:

a plurality of individual light sources arranged in an array for providing a plurality of individual visual indications;
first means coupled to the plurality of individual light sources for controlling the individual light sources to flash intermittantly and with all but one of the light sources controlled to flash at regular intervals and with one of the light sources controlled to flash at irregular intervals;
a plurality of second means coupled to the plurality of individual light sources for selecting any individual one of the plurality of light sources judged by the test subject to be the light source flashing at irregular intervals;
third means coupled to the first and second means for randomly selecting one of the plurality of light sources to flash at irregular intervals after one of the second means is selected by the test subject,
coincidence means coupled to the first and second means to produce a coincidence signal when the test subject selects the particular one of the plurality of light sources flashing at irregular intervals;
a first counter means coupled to the coincidence means for counting each production of a coincidence signal to count the number of correct selections by the test subject;
and
a visual indicator coupled to the first counter means for visually displaying the number of correct selections and additionally including lockable means, including locked and unlocked positions coupled to the visual display for shielding the visual display when in the locked position and exposing the visual display when in the unlocked position.

Apparatus for performing a self-administered time perception test by a test subject, including;

a plurality of regular oscillators each producing oscillations at regular intervals;
a plurality of selector gates corresponding in number to the plurality of regular oscillators and with each selector gate having at least first and second oscillator inputs and at least one gate input and with each selector gate receiving an input at the first oscillator input from one of the regular oscillators;
at least one irregular oscillator producing oscillations at irregular intervals coupled to the second oscillator inputs of each of the plurality of selector gates;
a random selector producing a select signal coupled to the gates to control one of the gates to output the irregular oscillations and the remaining selector gates to output the regular oscillations;
a plurality of light sources corresponding in number to the selector gates and coupled to the outputs of the selector gates for flashing in accordance with the oscillations produced by the oscillators;
a plurality of test buttons corresponding in number to the number of light sources for selecting any individual one of the plurality of light sources judged by the test subject to be the light source flashing at irregular intervals, and a plurality of coincidence detectors corresponding in number to the number of test buttons and with each coincidence detector coupled to one of the test buttons and with all of the coincidence detectors coupled to the random selector and receiving the select signal to have one of the coincidence detectors produce a coincidence signal when there is a coincidence between the select signal and the actuation of the one of the test buttons corresponding to the light source flashing at irregular intervals.
