Sometimes during a quiz, we know that we know the answer to a question even though we can鈥檛 bring it immediately to mind. How?
Here鈥檚 an example. Question one: what is the capital of France? I immediately know that the answer is Paris. Question two: what is the capital of ? I immediately know that I do not know the answer. Question three: what is the capital of Portugal? I know that I have the answer in my brain, but I can鈥檛 quite remember it. Then, as the answer is read out I agree that it is Lisbon.
In some cases, for hours afterwards I know that I know the answer to something but can鈥檛 recall it. So how is it that I can know that I know the answer to a question but, despite that, still cannot retrieve that piece of information?
