1. Intro to Sensation and Perception
What is the difference between sensation and perception, and how do they work? You'll get to see how the mind handles and differentiates between multiple sensations in this introduction.
2. Sensory Adaptation & Habituation: Definition & Examples
Ever notice how, after a while, a dark room seems less dark? Watch this lesson to find out about sensory adaptation and habituation, why we become desensitized to stimuli after a while, and what happens when things change.
3. How Does Vision Work?
How do your eyes and brain work together to turn light into images? You'll learn about the working components of the eye and take a look at two theories of color perception.
4. The Eye and Eyesight: Large Structures
Would you be able to see anything without a lens in your eye? Does the lens change shape? Does the iris? What structure gives you your eye color? Find out all of this and about things like the ciliary muscles and the cornea as we delve into this lesson.
5. How Receptors of the Eye Conduct Information via the Optic Nerve
You will learn how your eyes are able to see the image in front of you thanks to special cells called photoreceptors. In addition, these receptors have very important proteins called rhodopsin and photopsin; and all of these things work together to transmit information to your optic nerve.
6. Mechanics of Hearing
How do our ears transform sound into signals that our brains can process? In this lesson, you'll cover properties of sound waves and how they interact with key parts of the ear.
7. The Inner Ear: Sense of Balance and Hearing
Learn how water is important when it comes to your inner ear, cochlea, and sense of hearing. Find out what cool names like the bony labyrinth, semicircular canals, ampulla, and vestibule mean.
8. The Ear: Hair Cells, Organ of Corti & the Auditory Nerve
In this lesson, you'll learn the most important things about cranial nerve VIII, the auditory nerve and the Organ of Corti. In addition, you'll realize that even though you may not like it, your ears are quite hairy thanks to hair cells.
9. The Ear: Middle Structures and Hearing Functions
Find out about the malleus, incus, and stapes. You'll learn about the smallest bones in your body and find out what the ossicles are for. Finally, you'll find out how the oval window plays an important role in the transmission of sound.
10. Anatomy of the Ear's External Structures
What is the pinna? Is it the same thing as your earlobe? Does the eardrum have anything to do with the tympanic membrane? Find out as we explore all of this and other important structures involved in the sensation of hearing as sound enters your ear.
11. Taste, Touch and Smell
How do taste, touch and smell work? Also, what is proprioception? Throughout this lesson, you'll get a detailed description on each of these remarkable senses.
12. Perceptual Development
Why are some senses more developed than others for a newborn? You'll learn which senses are initially important for infants to bond with and recognize their mothers and which one is still in development after birth.
13. Attention and Top-Down vs. Bottom-Up Processing
Are you a big-picture person or do you get caught up in the details? Explore two ways that you can use your cognitive resources to focus your attention. This lesson provides both the details and the big picture for top-down and bottom-up processing.
14. Depth Perception
How do our brains make 3-D images out of 2-D inputs? In this lesson, you'll explore various visual cues that require either one eye or both eyes. Prepare to look at depth perception in a new way.
15. Steps of the Perceptual Process
Did you ever wonder how we choose what we see? In this lesson, we will learn about the perceptual process. In the perceptual process, we will learn how we select, organize, and interpret visual information.
