Ch 1: Perceptual Processes of the Brain

About This Chapter

With this overview of perceptual processes of the brain, enhance your understanding of sensory adaptation, the law of proximity, and optical illusions. Concise but filled with important details, the lessons are designed to help you with homework or test preparation.

Perceptual Processes of the Brain - Chapter Summary

While studying this chapter, you will heighten your understanding of how the brain perceives our surroundings. Included in these lessons is an explanation for why we become desensitized to stimuli as time passes. This chapter can also help you comprehend concepts of Gestalt psychology. After reviewing the lessons, you should be ready to do the following:

  • Define sensory adaptation and habituation
  • List the steps of the perceptual process
  • Provide examples of perceptual organization
  • Recall principles of Gestalt psychology
  • Explain the law of proximity
  • Define perceptual constancy in psychology
  • Discuss how optical illusions play tricks on our perception

These lessons facilitate easy comprehension of ideas related to perceptual processes of the brain. Key words are highlighted in bold for fast recognition and review. A brief quiz is available to test your knowledge of each lesson, and the quizzes can be printed for use as a study tool.

Sensory Adaptation & Habituation: Definition & Examples

1. Sensory Adaptation & Habituation: Definition & Examples

Sensory input is the information that a person's senses receive from their external environment. Explore how sensory adaptation and habituation can cause people to become less aware of sensory input.

Steps of the Perceptual Process

2. Steps of the Perceptual Process

The three stages of the perceptual process, which include selection, organization, and interpretation, along with personal factors, affect the processing of visual stimuli and also the perception of oneself. Learn to define the perceptual process and its stages, and also how to identify the factors that affect people's perceptions of others.

Perceptual Organization: Definition & Examples

3. Perceptual Organization: Definition & Examples

To make sense of what we see, the brain groups visual elements together in a process called perceptual organization. Discover the meaning of perceptual organization and why it's important, and see how it can be applied to mathematical representations as well as geometric shapes.

Gestalt Psychology: Definition & Principles

4. Gestalt Psychology: Definition & Principles

Gestalt psychology is a school of thought based on the laws of perceptual organization. Discover the definition of basic concepts and principles of Gestalt psychology and how the laws of perceptual organization work through illustrative examples.

Law of Proximity: Examples & Overview

5. Law of Proximity: Examples & Overview

The Law of Proximity is present in everyday life and deals with the grouping of objects near one another. Learn about the overview and definition of the Law of Proximity, some examples of the law, and what perceptual organization is.

Perceptual Constancy in Psychology: Definition & Examples

6. Perceptual Constancy in Psychology: Definition & Examples

Perceptual constancy refers to the tendency to perceive an object that you are familiar with as having a constant shape, size, and brightness despite any changes in stimuli that occur. Learn more about the definition of perceptual constancy and look at some examples.

What Are Optical Illusions? - Definition & Types

7. What Are Optical Illusions? - Definition & Types

An optical illusion is a visual experience that plays tricks on the brain's perception. Learn about the three major types of optical illusions, cognitive, literal, and physiological, and how they stimulate the brain in unique ways to cause misperception of reality.
