Document Summary

In general, is a way to understand how people make choices when asked to tell you whether there was a signal there or not. Example, in the shower waiing for phone to ring how certain do you need to be that you actually heard the phone ring before you have to jump out and grab it. Response can either be that the signal was there or not. Compare probability to hit and false alarm, how likely are you to say signal was there. You can make chart to show the responses and signals. Indicate whether the probability of making a response decreases and increases d" = d prime. How good a person is at a task, detecing a sound. D" prime is high, making a lot of correct responses. You need a lot of correct responses, hit and correct rejecions. Criterion really strict: how likely are you to say whether the signal was there regardless of what happens.
