About This Chapter
Behavioral Genetics Overview - Chapter Summary
One of the more significant topics in the fields of neuroscience and behavior is a particular field known as 'behavioral genetics.' The video and text lessons in this chapter will help you understand both the environmental and genetic links to behavior. You'll explore research methods used in the field of human genetics and get the definition of key terms. Review these lessons to learn about topics such as:
- The interaction between genes and environment
- The relationship between genes and psychological disorders
- Genetic predisposition
- The disease model and genetic model of substance abuse
- The definition and examples of comorbidity in psychology
- Research methods in human genetics
You can test yourself on these topics by answering the questions in the chapter's practice quizzes and final exam. If you would like further clarification on specific points, the chapter offers you the option of messaging the lesson instructors directly. You can also use your personal Dashboard to see how much learning progress you've made as you complete the lesson.
1. Types of Studies in Behavioral Genetics: Twin, Family & Adoption
Are you destined to inherit your mother's penchant for collecting old postcards or your father's constant worry that something bad is about to happen? Find out with this lesson, which delves into the world of genetic and environmental behaviors and personality traits.
2. Gene-Environment Interaction
The following lesson explores how genes and a person's environment influence behavior and outward expression of traits. A short quiz will follow the lesson to check your understanding of this timely topic.
3. Genetic Influence on Psychological Disorders
Do genetics play a role in psychological disorders such as schizophrenia? What do we know about any genetic links? Does environment matter? Find the answers to these questions and more in this video lesson.
4. Genetic Predisposition: Definition & Explanation
To be genetically predisposed to anything can be scary, but are there other factors that make you more or less susceptible to the condition? Find out as we discuss biological and behavioral issues as they relate to nature and nurture.
5. Disease Model & Genetic Model of Substance Abuse
Why do some people become addicted to drugs and alcohol, while others don't? In this lesson, we'll examine two theories that try to answer that question in terms of biology: the disease model and genetic model of substance abuse.
6. What is Comorbidity? - Definition & Examples in Psychology
Comorbidity is the existence of more than one disorder or disease at the same time. In this lesson, you will follow a fictional psychologist who explains what comorbidity is and when it is likely to occur.
7. Human Genetics Research Methods: Pedigrees and Population Genetics
Have you ever wondered how people study human genetics? Do you know what a pedigree or a complex disease is? In this lesson you'll learn about some of the techniques that human geneticists use and what pedigrees and complex diseases have to do with human genetics.
8. Biological Influences on Human Behavior: Genetics & Environment
Humans are a product of both our genetic makeup and our environmental surroundings. Does one influence our behavior more than the other? It can be difficult to tell, but there are ways that scientists can better understand why we do the things we do.
