Study Guide Overview

This study guide covers heredity, environment, and behavior, focusing on the interaction of nature and nurture. It explores the evolutionary perspective on behavior, including natural selection and adaptive behaviors. Finally, it examines research methods like twin, family, and adoption studies used to investigate genetic influences.

AP Psychology (2025) Study Guide: Heredity, Environment, and Behavior

Hey there, future AP Psych master! Let's dive into the fascinating world of how our genes and experiences shape who we are. This guide is designed to help you feel confident and ready for test day. Let's get started!

Unit 2: Biological Bases of Behavior

Nature vs. Nurture: The Great Debate (and how it's not really a debate!)

Key Concept

It's not nature versus nurture, but nature via nurture! They're always interacting.

  • Nature (Genes): Think of your genes as the blueprint you inherited from your parents. 🧬
    • These genes give you certain physical traits (like eye color and height), behavioral tendencies, and mental abilities.
    • These are the characteristics you're born with, thanks to your unique genetic makeup.
  • Nurture (Environment): Everything else falls under "nurture"—the world around you that shapes who you become.
    • This includes family interactions, education, culture, and all your life experiences.
    • These environmental factors mold your personality, beliefs, and behaviors as you grow.
  • The Interplay: Nature and nurture work together in a complex dance to determine your individual traits. It's not a question of one or the other, but how they interact and influence each other.
Memory Aid

Think of it like baking a cake: Genes provide the ingredients (nature), but the way you mix them, the oven temperature, and the frosting (nurture) all affect the final outcome.

  • Example: A child may have a genetic predisposition for musical talent (nature), but without exposure to instruments and lessons (nurture), that potential may go unrealized.
Common Mistake

Don't get bogged down in specific genetic concepts like genotypes, phenotypes, DNA, chromosomes, or dominant and recessive genes. The AP exam won't ask about these details.

Evolutionary Perspective on Behavior

  • Natural Selection: Evolutionary psychology looks at how natural selection has shaped our be...

Question 1 of 9

Hey there, future AP Psych star!🌟 Which of the following statements BEST describes the relationship between nature and nurture?

Nature and nurture are opposing forces, with one always being dominant

Nature (genes) solely determines our traits, while nurture (environment) has no impact

Nurture (environment) is the only factor that molds our personalities and behaviors

Nature and nurture interact in a complex way to shape our individual traits
