Participants were given a true or false quiz in which they had to guess the meaning of words in a foreign language and were then given the correct answer after each item. However, this process was occasionally interrupted by a tone. When this tone occurred, participants were instructed to press a key and then continue with the quiz. Later these participants took the same true or false quiz but without the correct answers. The words that the participants had been informed were false were more likely to be misremembered as being true later if they had been interrupted by the tone while learning this information.
