Document Summary

Tap your nger every time you see the word red . Looking for a particular signal, its either there or not there and you either respond or don"t respond. Correct rejection: had the right response to the stimulus (stimulus is not there and you respond no ) Hit: had the right response to the stimulus (stimulus is present and you respond yes ) Type 1 error: stimulus is absent, but respond yes (false alarm) Type 2 error: stimulus is present, but respond no (miss) Examples: traf c light, air traf c controllers, cross walk signals. Driving simulators helps the design of signage be more ef cient (ie. signs in a tunnel only seen for a short second, so they need to be simple and repeated) This is a problem because not everyone is a young and healthy person we should be targeting everyone (whether young or old)
