Now watch patient ML doing the plausibility-judgments task. There will be a beep, then the sentence will play. ML has been told to press the left key if he thinks the sentence is sensible and the right key if he thinks it is silly. This judgment is based on the event, not on any aspect of the choice of words. He has also been told to work quickly, but not at the expense of accuracy. The demo you will watch comprises practice items. So, if ML makes an error, he is buzzed and has to restart the task by pressing the spacebar. Notice how the sentences vary in structure. The approximate time he took to respond will be displayed on the screen; so notice the difference between the structures. He is particularly slow on the fifth one because of its more complex structure.
