In this experiment, you'll play a simple game.

In each turn of the game, you'll see two images. You'll be able to choose between them; when you choose an image, you will either get +5 coins, or +0 coins to your coin bank. Your goal is to end the game with as many coins as possible.

If the images display musical notes, that means that you have to use your mouse to click on each image. It will then play a musical phrase, which you can only play once - so pay attention to what you hear.

It's your job to figure out which image will give you more coins to do well at the game. This may not always be easy and it may take a little while to learn, but keep playing the game and trying to earn as many coins as you can.

To choose the option on the left, press the ← key on your keyboard (the left arrow key). To choose the option on the right, press the → key on your keyboard (the right arrow key).

Click the ENTER key on your keyboard to begin!

To choose the option on the left, press the ← key on your keyboard (the left arrow key).

To choose the option on the right, press the → key on your keyboard (the right arrow key).

If you see two musical notes, you must click on both of them using your mouse to listen to the audio before responding.

Great job! Now, you'll just make one more choice.

Even though the options here look a little different, the same pattern that you just learned also applies here.

So, based on what you know, take your best guess about which option is worth more points.

When you're ready to continue, click the ENTER key on your keyboard.
