Ch 7: Physical Development in Infancy and Toddlerhood

About This Chapter

Watch online psychology video lessons to learn about sensorimotor development and perceptual abilities in infants and toddlers. These engaging lessons are just a portion of our online study guide and video collection.

Physical Development in Infancy and Toddlerhood - Chapter Summary and Learning Objectives

Instructors teaching this chapter on infant development begin by introducing you to two different views of human growth. You can also weigh in on whether environment or genetics play a greater role in our development and discover developmental milestones in infants' ability to taste, touch, hear, see and smell. A lesson on the leading cause of death among children under 12 months of age wraps up this chapter, which is designed to teach you how to:

  • Differentiate between the cephalocaudal and proximodistal principles
  • Explain changes to sensorimotor skills in the first two years of life
  • Describe the development of infants' and toddlers' perceptual abilities
  • List risk factors for sudden infant death syndrome

Video Objectives
Defining the Principles of Growth in Psychology Understand how the cephalocaudal and proximodistal principles of growth are used to explain human development.
Motor, Sensory & Brain Development in the First Two Years of Life Examine developmental milestones in motor and sensory functioning from birth to age two.
Sleep-Wake Patterns in the First Two Years Learn about the volume and type of sleep infants and toddlers get during the first two years.
Infant Perceptual Development and the Five Senses Survey the sensory abilities of infants. Identify the role of habituation in studying infants' perceptual development.
The Visual Cliff Experiment: Purpose & Significance Get an introduction to the nature vs. nurture debate. Explain the uses of the visual cliff experiment to study infants' depth perception.
Sudden Infant Death Syndrome: Risk Factors & Prevention Discuss research and statistics related to sudden infant death syndrome (SIDS). Identify risk factors and methods for preventing SIDS.

Defining the Principles of Growth in Psychology

1. Defining the Principles of Growth in Psychology

Everyone grows and changes throughout life. But how does this development occur? In this lesson, we'll look at the two main principles of growth and development: the Cephalocaudal Principle and the Proximodistal Principle.

Motor, Sensory & Brain Development in the First Two Years of Life

2. Motor, Sensory & Brain Development in the First Two Years of Life

Babies grow and change so much in the first two years of life, and many of those changes are directly tied to the brain and its key functions. In this lesson, we'll look at brain, motor and sensory development in infants.

Sleep-Wake Patterns in the First Two Years

3. Sleep-Wake Patterns in the First Two Years

As every new parent knows, babies sleep differently than adults do. In this lesson, we'll look at two key changes in sleep patterns that develop in the first two years of life, the volume and type of sleep.

Infant Perceptual Development and the Five Senses

4. 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.

The Visual Cliff Experiment: Purpose & Significance

5. The Visual Cliff Experiment: Purpose & Significance

How do babies perceive the world around them? In this lesson, we'll examine the famous visual cliff psychology experiment and how it relates to the classic psychology debate of nature versus nurture.

Sudden Infant Death Syndrome: Risk Factors & Prevention

6. Sudden Infant Death Syndrome: Risk Factors & Prevention

The leading cause of death for children under the age of one is a large mystery to many people. In this lesson, we'll look closer at Sudden Infant Death Syndrome, including risk factors and prevention measures.
