Groningen Reaction Time Test
The Groningen Reaction Time test is a simple test of reaction time. This test is part of the protocol for the Groningen Fitness Test for the Elderly.
- purpose: to measure reaction time in elderly persons
- equipment required: a specially developed timer, which is connected to a handheld module with a display light in the middle and a button on top, much like a stopwatch.
- procedure: The participant holds the module in the preferred hand and when the red light comes on must respond as quickly as possible by pushing the button. The reaction time (in milliseconds) is displayed on the timer. The time between the visual signals ranges between 4 and 9 seconds. After three practice trials, 15 trials are recorded.
- scoring: The score recorded is the median of the 15 trials.
- disadvantages: an apparatus specifically for this test needs to be obtained.
- target population: this test was designed specifically for the elderly population.
