Decision Time

Decision Time measures reaction time

"On a panel, eight lamps were arranged in a semicircle 5·5 inches from a central button (the home key). The index finger was placed on the home key. Following a warning tone, one of the eight lamps flashed and the subject pressed the button in front of the illuminated lamp. The decision time is the time taken to lift the finger from the home key. Simple and choice decision times for each of two, four and eight lamps were measured over twenty trials."
