1. Intro to Developmental Psychology
Why do we study psychological development? People change over their lifetimes, and developmental psychology helps us explore what changes and what stays the same. Learn about some of the big names in this field whose work and theories you'll explore in other lessons
2. Overview of Life Span Developmental Psychology
Developmental psychology studies the way people change and grow. In this lesson, we'll look at the principles of how people develop across the life span, including multidimensionality, multidirectionality, and plasticity.
3. How Genetics and the Environment Interact in Human Development
Everyone is different. But what makes a person unique? In this lesson, we'll examine the way genes and the environment affect who a person is, including looking at the nature vs. nurture debate and looking at how nature and nurture influence one another.
4. Twin and Adoption Studies: Practices & Findings
What is more influential, nature or nurture? How can scientists know for sure? In this lesson, we'll look at studies designed to separate the effects of genetics and environment on people's behavior, twin and adoption studies.
5. Cross-sectional, Longitudinal & Sequential Designs: Advantages & Disadvantages
This lesson examines the three main ways of conducting research on adults and older individuals. Specifically, we will examine the three types, some of their advantages, and some of their disadvantages.
6. Overview of Genetics
We view manipulation of genes in our crops and livestock as a recent development. Yet, man has been manipulating the genetic makeup of his food for thousands of years through cultivation and breeding. This lesson will begin to help you understand how genetics works.
7. The Genome
There are approximately 3 billion bases in the human genome. In this lesson, you'll learn more about the genome and its organization into chromosomes. We think about DNA often as the blueprint for life, but we can also think of it as the recipe for life with the nucleus being the library.
8. The Genetic Code: Influence of Mitosis, Meiosis & Crossing Over
In this lesson, we will learn what the genetic code is and how it can be affected by mitosis, meiosis and crossing over. When mistakes are made and genes are altered, it can have a negative impact on human development.
9. Prenatal Development
How is prenatal development related to psychology? How are minds forming in the womb still linked to the outside environment? This lesson explores the stages of prenatal development and a mother's ability to affect her unborn child.
10. Prenatal Stages and Development: Germinal, Embryonic & Fetal Period
In the 9 months before a baby is born, there is an enormous amount of prenatal development. In this lesson, you will explore the following stages of prenatal development: the germinal period, the embryonic period, and the fetal period.
11. Genetic Abnormalities in Human Growth and Development
What are mutations and other chromosome abnormalities? How can these abnormalities affect human development? What are some common genetic disorders and their causes? Learn the answers to these questions in this lesson.
12. Prenatal Genetic Counseling and Assessment
When expecting a baby, many couples are concerned with the possibility of something being wrong with the baby's health. In this lesson, we'll explore genetic counseling, including who should consider it and what to expect.
13. The Prenatal Environment and Hazards to Healthy Prenatal Development
In this lesson, learn about the prenatal environment and what can be harmful to prenatal development. Learn about the hazards of drugs, alcohol, tobacco, disease and environmental pollutants during pregnancy.
14. The Impact of Mother's Emotional and Physical State on the Prenatal Environment
An unborn child and its mother are connected both physically and emotionally. Learn how prenatal development is affected by both the emotional and physical state of the mother in this lesson.
15. Infertility: Causes and Potential Options
Trouble having a baby may be a result of a woman or man's reproductive problems. This lesson discusses some common and important ones as well as the general treatment strategies employed to combat them.
16. Treatment for Infertility
There are quite a few different kinds of treatment options for both men and women. They include drugs, surgery, hormone therapy, and more advanced techniques this lesson will describe.
17. Identifying the Reflexes of Newborns
Reflexes allow babies to survive the first few years of life. In this lesson, we'll look at some of the major reflexes of infants, including those that indicate a healthy nervous system response and those designed to help a baby feed itself.
18. The Newborn: Capabilities, Growth, and Developmental Milestones
Newborn growth and development is an amazing process! In this lesson, you will discover how babies learn, when they acquire certain abilities, and what reflexes they are born with.
19. Infant Development
Watch babies brave heights at the insistence of their smiling mothers! You'll learn how instinct and attachment can help infants explore their environments through the visual cliff experiments.
20. 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.
21. Memory and Information Processing in Infants
The way adults think is vastly different from the way that children think. In this lesson, we'll explore cognitive development and look at how infants begin to think like adults, including the concepts of information processing and memory.
22. Language Learning in Infants and Toddlers
Language development is a long process, and there are many types of speech that babies take part in. This lesson explores language development and some key types of speech, including child-directed speech, syncretic speech, and telegraphic speech.
23. Cognitive Development in Infants: Object Permanence & Sensorimotor Periods
There is no time like infancy - it is the first exposure people have to the world. According to Jean Piaget, there are six stages infants go through as they develop cognitively and learn to act in their environment.
24. Infant Creativity and Intelligence
How is infant intelligence measured? In this lesson, you'll learn to recognize common measures of infant intelligence as well as what information these measures can provide.
25. Infant Attachment Theory: 4 Stages of Parent-Infant Attachment
Relationships with others play a large role in our lives. These relationships start from birth and continue to develop through adulthood. This lesson will describe the stages of parent-infant attachment, define types of attachment anxiety experienced by infants and discuss the debate over which forms stronger attachments: food or comfort.
26. The Strange Situation Test: Ainsworth's Attachment Theory for Infants
The attachment and bonds infants develop early in life play a critical role in their interactions with others as they grow. This lesson will introduce the Strange Situation experiment conducted by Mary Ainsworth and discuss the four infant attachment types identified through the experiment.
27. Parenting Styles
How do parenting styles differ from one another, and which are most effective? You'll follow expectant parents, Mary and Larry, as they walk their neighborhood and try to learn from other parents.
28. Erik Erikson's Eight Stages of Psychosocial Development: Conflicts & Growth
Erikson identified eight stages of psychosocial development, with each stage presenting a conflict that must be overcome. This lesson will discuss the conflict and growth associated with each stage of development.
29. Cognitive Development in Children and Adolescents
If you were to observe children growing into their teenage years, you would notice their thinking and understanding develops over time. In this lesson, you will learn about the specific stages of mental growth in children and adolescents as outlined by Jean Piaget.
30. Piaget's Stages of Cognitive Development
How does a child's thinking change as she gets older? When does she learn about object permanence, conservation and abstract reasoning? You'll see that thought processes we take for granted as adults are actually important milestones in a child's cognitive development.
31. Lev Vygotsky's Theory of Cognitive Development
The role of culture and social interactions are imperative to cognitive development, according to psychologist, Lev Vygotsky. This lesson will discuss how social interactions play a role in cognitive development of children, provide an overview of Vygotsky's cultural-historical theory and describe the stages of speech and language development.
32. Child and Adolescent Development: Developmental Milestones & Nature vs. Nurture
How does a child develop cognitively? Which influences development more - genetics or the environment? How important are early experiences in the growth and cognitive development of a child? These are some of the major questions that guide the work of researchers in the field of educational psychology. This lesson will begin to address these questions by describing the basic principles that characterize child and adolescent development.

44. Gender Identity and Roles in Early Adulthood
As people age, they begin to think about how their gender affects who they are. Watch this lesson to find out how people construct their gender identity, how society defines gender roles, and how both of these things can impact a marriage.
45. Gender Role Changes in Middle Adulthood
Middle adulthood is a time of great change for most people. But men and women experience those changes differently. In this lesson, we'll take a look at the way gender impacts middle age, including the famed mid-life crisis and gender crossover.
