Chapter 2: Biological Bases of Behavior
In this episode of Psychology for Students, Angela takes you through a detailed, easy-to-understand review of Chapter 2: The Role of Biology in Psychology from Psychology in Your Life, 4th Edition by Grison and Gazzaniga.
We break down the key concepts you need to know for your quiz—but more importantly, we help you understand how these ideas apply to your real life.
Learn how your nervous system works like your body’s communication network, how different parts of your brain function, and how your brain sends messages through specialized cells called neurons.
You’ll also explore the role of neurotransmitters like dopamine, serotonin, and GABA—and understand why balancing these chemicals matters for your mood, memory, and mental health.
And we’ll talk about the ongoing debate between nature and nurture—and why the truth is, it’s not one or the other. It’s both. Your biology and your environment work together to shape your thoughts, emotions, and behavior through a process called epigenetics and neuroplasticity.
If you’ve ever wondered why you feel stressed, how your brain helps you survive, or how trauma and experiences affect your mental health—this episode is for you.
Tune in, relax, and let’s get you ready for success on your Chapter 2 quiz… and beyond.
Psychology for Students — understanding your mind, your world, and your future — one episode at a time.
