In our ScienCentral News video Tip of the Tongue Learning, we report on new psychology research from McMaster University. There, cognitive psychologist Karin Humphreys and her colleague Amy Beth Warriner used some tricky questions to test what happens to people when they get a word stuck on the tip of their tongue.
Test yourself with these questions from the experiment to find out if these words make you feel that maddening sensation--where you remember the answer, but you just can't get it out. Scroll down for the answers.
One warning: Humphrey and Warriner tossed in some unanswerable questions to figure out if the volunteers in their experiment were having fake tip-of-the-tongue experiences, where you feel like an answer is stuck on the tip of your tongue, but in fact, there is no answer to the question. After you take the quiz, scroll down for the answers.
