About This Chapter
The Five Human Senses - Chapter Summary
The lessons in this chapter can help you develop an understanding of how the retina, optic nerve and other components of the eye's anatomy work together to turn visible wavelengths of light into visual images. Knowledgeable instructors also introduce you to the tiny bones in the ear responsible for picking up vibrations that the brain interprets as sound. The receptors enabling taste and smell are covered as well, along with the role of the skin in detecting the pressure and sensation we perceive as touch.
Wrap up your study of the five human senses by examining how these sensory abilities mature as we progress beyond the developmental stage of toddlerhood. You can also explore the role of habituation in this process. Lessons are designed to teach you the following:
- Eye anatomy and vision
- Depth perception
- The mechanics of hearing
- Receptors for taste, touch and smell
- Characteristics of infant perceptual development
There's quite a bit of complicated anatomy involved in the study of how we interpret seemingly simple sensory information. Fortunately, the video lessons in this chapter include plenty of illustrations to help you take it all in. There are also corresponding transcripts if you'd like to scroll through the material at your own pace. Additionally, self-assessment quizzes are available to help affirm your understanding of the topics covered here.
1. 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.
2. What is Depth Perception? - Definition, Cues & Examples
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.
3. Mechanics of Hearing & How the Brain Processes Sound
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.
4. Taste, Touch & Smell: Proprioception & the Somatosensory System
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.
5. Perceptual Development in Infants
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.
6. Infant Perceptual Development and the Five Senses
What is habituation and how does it affect perceptual development in an infant? Learn the answer to this question and more as this lesson explores sensory development in infants.
