From biology to beliefs to childhood experiences.
What if I told you that the same feeling of sadness could have seven completely different explanations? By the end of this lesson, you’ll be able to recognize them all.
Welcome back to Psych 101. I’m really glad you’re here for Lesson Two, where we explore how psychologists explain human behavior.
Today’s guide is our friend Moody Mountain Frank, the character you chose in the community poll. If you want to vote on future characters, shape examples, or guide upcoming lessons, make sure you’re subscribed so you don’t miss anything.
Let’s dive into the seven major theoretical perspectives in psychology—and discover how each one explains Frank’s moodiness differently.
Have you ever grabbed your phone instantly when you hear a notification—even before you know what it is? That’s learned behavior.
The behavioral perspective focuses on:
This perspective was shaped by Ivan Pavlov and B.F. Skinner.
Pavlov paired a bell with feeding time until the dogs learned that the bell meant food. Eventually, the bell alone made them salivate.
This learning process is classical conditioning.
From a behavioral lens:
In this view, Frank’s sadness is a learned pattern shaped by his environment.
Imagine someone leaves you “on read.” Do you assume they’re busy—or worry that you did something wrong?
That instant interpretation shows how powerful our thoughts are.
The cognitive perspective focuses on:
Key figures include Jean Piaget and Noam Chomsky.
Frank waves at someone. They don’t wave back.
The event is neutral.
The thought (“They’re ignoring me”) creates the sadness.
From this lens:
Change the thought → change the feeling.
What if the issue isn’t learned behavior or negative thinking?
What if the answer is already inside Frank?
The humanistic perspective focuses on:
Key figures: Carl Rogers and Abraham Maslow.
From this view:
The question becomes:
What does Frank need in order to thrive?
Have you ever had a dream so strange you wondered where it came from?
According to the psychodynamic perspective, it comes from the part of your mind hidden beneath awareness.
This approach emphasizes:
Developed by Sigmund Freud, represented by his iconic iceberg model.
From this lens:
Think about the rush you feel after a workout or the warmth of laughing with friends. Those aren’t imaginary—they’re chemical.
The biological perspective examines:
Frank’s sadness might stem from:
In this view, the story isn’t psychological—it’s physiological.
Have you ever noticed how your behavior changes depending on who you’re with?
Culture plays a massive role in shaping identity, behavior, and emotions.
The sociocultural perspective emphasizes:
Associated with Lev Vygotsky.
From this viewpoint:
This lens reminds us that the environment is powerful.
Why does rejection hurt so much?
Why does public speaking trigger fear?
The evolutionary perspective says behavior is shaped by ancestral survival needs.
Rooted in Charles Darwin’s ideas, this approach explores:
For Frank:
Sadness and fear are ancient alarms designed to keep humans safe
Being ignored feels dangerous
Thousands of years ago, exclusion meant losing protection
Now that we’ve explored how psychologists explain behavior, let’s look at what psychologists do.
Each subfield applies these perspectives in different ways.
In Lesson Three, we’re exploring how psychologists turn ideas into actual science through research methods, experiments, and ethical guidelines.

I’ll see you in the next lesson.
