Instructions

In this experiment, you will be presented with one or three letters that you will need to remember, followed by a tone you will respond to.

  1. At the beginning of each trial you will see a fixation ‘+’ which you should focus on. When you are ready to begin a trial, press the space bar.
  2. You will be presented with either one letter or three letters that you will need to remember. Then you will hear a tone that will be either high-pitched or low-pitched. Your task is to respond to the tone as quickly and accurately as possibly by pressing the ‘D’ key if it is a high-pitched tone and the ‘K’ key if it is a low-pitched tone. Before going any further, click on the buttons below to hear the two tones.
  3. After you respond to the tone, you will be prompted to type in the letters in the order they appeared. You will then begin the next trial.

You will complete 10 practice trials and 80 experimental trials. At the end, you will be shown your results for trials where you responded correctly. Before you begin, click on the buttons below to hear the two tones. When you have heard the tones, click the ">" button to begin.
