Akeelah extended her arm in front of her and then extended one of her fingers. She focused on that finger. Next, she closed her left eye without moving her head; then she opened her left eye and closed her right eye without moving her head.

In laboratory settings, people can process and respond to information outside of their awareness.

Two lines appear to be a different length, though in reality they are the same length. This is known as the ________ illusion.

Müller-Lyer

What does the place theory of pitch perception suggest?

Receptors on different portions of the basilar membrane are sensitive to sounds of different frequencies.

As you are talking to a friend on your cell phone, you might find that you can't hear them because they are speaking very softly. If you ask them to "speak up," from a physical perspective you are asking them to ________ of the sound waves they are producing.
