Ch 5: AP Psychology: The 5 Senses & Psychology

About This Chapter

Watch video lessons about the five senses and psychology to learn about eye structure, psychophysics, sensory adaptation, and more. These lessons are just a portion of our AP Psychology course.

The 5 Senses and Psychology - Chapter Summary and Learning Objectives

Our five senses - sight, hearing, smell, taste, and touch - help us navigate through the world, but how does our brain know what to do with all that information? In this chapter, you'll learn about the biological structures involved in gathering data and how that data is interpreted by the mind. From the molecular to the body system level, these lessons explore the ways in which our senses affect, act on, and change our psyches. After completing this chapter, you should be able to:

  • Identify parts of the eyeball and explain what function each serves
  • Discuss how our brain turns 2-D vision into a 3-D rendering of the environment
  • Explain how we adapt both physically and mentally to changes in our surroundings
  • Map the pathways of sound through the structure of the ear
  • Understand how receptor molecules work

VideoObjective
Intro to Sensation and PerceptionLearn about psychophysics, which is how our mind interprets signals from our senses.
Receptor Processes and Sensory MechanismsExplore the biological processes involved in receiving information from our cells through receptor molecules.
How Does Vision Work?Study the structure of eyes and how our brain uses what they see.
Depth PerceptionLearn how our brains transform our vision into a three-dimensional map of the world.
Mechanics of HearingExplore the structure of ears and the ways our brain receives and interprets sound signals.
Taste, Touch, and SmellUnderstand how taste buds, odor receptors, and skin help our brains gather data about our surroundings.
Sensory Adaptation and HabituationLearn how our bodies and brains respond to changes in our environments.

Intro to Sensation and Perception

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.

Receptor Processes & Sensory Mechanisms

2. Receptor Processes & Sensory Mechanisms

How do we receive and interpret information from the world around us? In this lesson, we'll look at an overview of sensation and perception, including the differences between the two and the basic process of moving from one to the other.

Sensory Coding: Getting Messages from Receptors to Your Brain

3. Sensory Coding: Getting Messages from Receptors to Your Brain

When you stub your toe, you feel pain. But that's not all to the story: information about what your toe is feeling has to travel up to your brain. In this lesson, we'll look at the process of sending information from sensory receptors to the brain.

How Does Vision Work?

4. 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.

Mechanics of Hearing & How the Brain Processes Sound

5. 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.

Taste, Touch & Smell: Proprioception & the Somatosensory System

6. 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.

Sensory Adaptation & Habituation: Definition & Examples

7. 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.

What is Depth Perception? - Definition, Cues & Examples

8. 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.
