2.4. Procedure

At the beginning of each session, participants were given the following instructions:

"I will ask you a number of questions. Your job is to listen to each task and tell me what you think is the correct answer to each question. If you do not understand any question or you need to hear the question once more, feel free to ask for the sentence to be repeated. I cannot tell you when you have answered correctly. So you should pay full attention. Do the best that you can".

Participants were asked if they understood these instructions and then asked to begin. No participant indicated that they did not understand what was required.
