In this study, you will be tasked with quickly recognizing scenes.

On each trial, you'll be presented with a statement, such as The red block is on the blue block. Then you will be presented with a scene. Sometimes the scene will depict the same thing described by the statement, and sometimes it will depict something different.

Your job is to decide whether the statement is a correct description of the scene (which requires a "yes" response) or an incorrect description of the scene (which requires a "no" response).

For example, imagine that you were presented with the statement "The red block is on the blue block."

The following scene depicts a red block on a blue block. Therefore, the answer to the statement would be "yes", because the statement is a correct description of the scene.

In the experiment, you'll press the Y key for "yes".

Click Next to continue.

Now imagine again that you were presented with the same statement, "The red block is on the blue block."

The following scene depicts a red block below a blue block, not on a blue block. Therefore, the answer to the statement would be "no", because the statement is an incorrect description of the scene.

In the experiment, you'll press the N key for "no".

Click Next to continue.

The statements will be different from trial to trial, so it is important that you consider each statement carefully before you proceed to the scene.

For example, you might be presented with the statement "The red block is on the blue block."

Since the following scene depicts the blue block on the red block, not the red block on the blue block, you would respond "no".

Or you might be presented with the statement "The blue block is below the red block."

Although that is technically a possible description of the below scene, the blue block is not simply below the red block; the blue block is actually supporting the red block. Therefore you would respond "no" here as well.

There is no trick here: If you are paying attention, the answer on each trial will be obvious.

However: You will not have much time to respond! After a short time, the trial will end and you will be gently warned for being too slow.

So you must respond both accurately and quickly!

The whole study will take about 15 minutes; please stay focused!

(Note: When the experiment is done, you will be redirected back to SYSTEM's webpage where you will be given a completion code.)

First, to make sure everything is clear, we'll try some really easy trials for practice.

You will have unlimited time on these trials, so take your time. It is important during the practice that you understand the statements and how they relate to the scenes you see.

Note that you will see the same two objects throughout the practice (a blue block and a red block). However, in the real experiment, the objects will be different.

Also note that in the real experiment, you will only have a limited time to respond!

Click "Start Practice" to begin.

You have finished the practice trials. The real experiment will now begin.

Note that on these trials, you will only have a brief time to respond once the scene appears, so you'll have to be quick! Just do the best you can.

Also note that the objects here will be different from those in the practice. They will be two books.

There will be periodic breaks interspersed throughout the study.

Great job so far. Keep the focus up!

Remember: Do your best to be as fast and accurate as possible.

Take a quick break. When you're ready to continue, click "Continue Experiment" below.
