Device and method for assessing cognitive speed
First Claim
1. A cognitive speedometer for the assessment of cognitive processing speed, comprising:
- (A) display means;
(B) means for entering data;
(C) means for generating original data and displaying on said display means the original data for copying by a user on said data entry means;
(D) means, operable only on the displayed original data correctly copied by the user on said data entry means, for generating and displaying on said display means different data on which the user is to perform a unit cognitive operation and then enter the resultant data on said data entry means; and
(E) means, operable only on the correct resultant data entered by the user on said data entry means, for determining the time required for the user to perform only the unit cognitive operation.

Abstract
A cognitive speedometer for the assessment of cognitive processing speed includes a display screen, a keyboard, and a processor for generating original data and displaying on the screen the original data for copying by a user on the keyboard. Only if the user copies the displayed original data correctly, the processor generates and displays on the screen different data on which the user is to perform a unit cognitive operation and then enter the resultant data on the keyboard, the resultant data having the same characters as the original data. Only if the user enters the correct resultant data, the processor determines the time required for the user to perform the unit cognitive operation.

16. A cognitive speedometer for the assessment of cognitive processing speed, comprising;
-
(A) display means; (B) means for entering data; (C) means for generating original data and displaying on said display means the original data for copying by a user on said data entry means; (D) means, operable only on the displayed original data correctly copied by the user on said data entry means, for generating and displaying on said display means different data on which the user is to perform a unit cognitive operation and then enter the resultant data on said data entry means, the resultant data having the same characters as the original data, said original, different and resultant data being numbers having no more than two digits each and the unit cognitive operation being the addition of 1 to or subtraction of 1 from the displayed different data; (E) means, operable only on the correct resultant data entered by the user on said data entry means, for determining the time required for the user to perform only a unit cognitive operation independently of the time required to physically enter the resultant data on said data entry means, said determining means determining the time as the difference between the time required to copy the displayed original data correctly on said data entry means and the time required to perform a unit cognitive operation on the displayed different data and then enter the resultant data correctly on said data entry means; (F) means for comparing the time required for the user to perform the unit cognitive operation with a established norm for the time required to perform the unit cognitive operation; and (G) prompting means for displaying on said display means at an appropriate time instructions for the user to copy the displayed original data and for indicating on said display means at an appropriate time the unit cognitive operation to be performed by the user on the displayed different data; said means for generating and displaying original data generating and displaying a sequence of such original data for copying before said means for generating and displaying the different data displays such different data. - View Dependent Claims (17, 18)

19. A cognometer comprising in combination in a single portable device:
-
(A) a speed monitor means including a cognitive speedometer for the assessment of cognitive processing speed; (B) a memory monitor means; (C) a concentration monitor means; and (D) means for selectively actuating one of said monitor means at a time; wherein said speed monitor means, memory monitor means and concentration monitor means, having a common data entry means and a common display means.

20. A method of assessing cognitive speed comprising the steps of:
-
(A) generating and displaying data on a display means; (B) testing the user'"'"'s speed of entering original data by displaying the original data on the display means and requiring the user to copy the original data on the data entry means; (C) testing the cognitive speed of the user by displaying different data on the display means and requiring the user to perform a unit cognitive operation on the different data and enter the resultant data corresponding only to the original data correctly copied by the user, on the data entry means; and (D) determining the time required for the user to perform only a unit cognitive operation on the displayed different data. - View Dependent Claims (21, 22)
