Scoring/Measurements
The T.O.V.A. measures a set of different variables to determine whether or not response times and attention is at the normal range for the sex and age of the test taker. Over 2000 people without attention problems were measured to determine what is a normal response time for the sex and age of the test taker as a basis for the interpretation provided.
- Response Time Variability: A time measurement of how consistently the microswitch is pressed.
- Response Time: A time measurement of how fast or slow information is processed and responded to.
- d' Signal Detection: A time measurement of how fast performance drops.
- Commission Errors: A measure of impulsivity: how many times the non-target is pressed.
- Omission Errors: A measure of inattention: how many times is the target not pressed.
- Post-Commission Response Time: A time measurement of how fast or slow a response is after a commission Error.
- Multiple Responses: A measure of how many times the button is pressed repeatedly. (Indicator of other problems)
- Anticipatory Responses: A time measurement how often a person is guessing rather than responding.
