| What is signal detection theory? | Detection theory or signal detection theory is a way to measure the ability to differentiate between information-bearing patterns called stimulus in living organisms and random patterns that distract from the information or "noise" consisting of background stimuli and random activity of the nervous system. |
| You are standing at a high point in complete darkness, can you see a burning candle 30 miles away? | Yes, because all other background stimuli is muted. |
| Your watch is ticking but you are worried about getting something to eat, will you hear the watch ticking while feeling hungry? | Possibly not because you are extra focused on getting food to eat, you may miss the stimuli associated with the watch because it is less important. |
| What is "noise" in signal detection theory? | Noise is all the extra stimuli present that the person doing the detecting is not looking for. |
| What is "a hit" in signal detection theory? | When a person properly identifies the stimuli they are looking for. |
| What is "a miss" in signal detection theory? | When a person improperly identifies the stimuli they are looking for. |
| What is "a correct rejection" in signal detection theory? | Properly rejecting something you intend to reject. |
