The
Psychology
of Media
Media is built by people who study people. Apps, ads and creators all compete for one limited thing: your attention. This module looks at how attention, emotion, persuasion and habits work, so you can notice when they're being used on you and decide for yourself.

You'll need: pencil, a phone or tablet with a feed you use, a few real ads (print or online), a timer and some coloured pens.
Principles
A first principle is a basic truth you can build on. Psychology is the science of how people think, feel and act. Media works on all three. Start with what you already notice about yourself.
What do I already know?
What is necessary?
Everything in this module is built from four bricks. Rate yourself on each one, then check the example to see if your rating holds up.
What is the objective?
By the end, you'll be able to spot the psychology in media and use it on purpose, not by accident.
- 01Explain why attention is limited and how hooks grab it.
- 02Name the persuasion tools in an ad.
- 03Explain why emotional and outrage posts spread.
- 04Describe the feed reward loop and build healthier habits.
- 05Spot framing and common cognitive biases.
- 06Run a 7-day experiment on your own media habits.
The list on the left is ours. Now make it yours. What do you want out of this?
How much do you know about the psychology of media right now? Shade the boxes in pencil. You'll come back at the end (p.9) and shade it again in pen.
Why start this way? When you know what you already have (1), what you need (2) and where you're going (3), you learn faster and you notice the gaps. Every module on the Media Path starts with these same three questions.
Attention is limited
Your brain can't process everything around you, so it filters. In 1953, researcher Colin Cherry studied how people can follow one conversation in a noisy room, now called the cocktail party effect. Hearing your own name cut through the noise is a famous example.
What makes us stop scrolling
| Hook | Why it works |
|---|---|
| A face | We tend to notice faces and expressions fast. |
| Movement | Sudden motion pulls the eye. |
| An open question | "You won't guess what happened…" leaves a gap we want to close. |
| Surprise | Something unexpected breaks the pattern. |
| It's about you | "If you live in Alberta…" feels personal. |
"Humans have a shorter attention span than a goldfish"
You may have seen the claim that our attention span is 8 seconds, shorter than a goldfish's. It went viral around 2015, but researchers who looked for the original evidence couldn't find a solid scientific study behind it. Attention depends a lot on what you're doing and how interested you are. Lesson: even facts about media can be hooks.
How strong is the hook?
A creator's video is shown to 10,000 people. 4,000 are still watching after 3 seconds; 1,500 watch to the end.
The first 3 seconds lost 6 in 10 people. That's why creators obsess over openings.
Scroll a feed for 2 minutes. Each time you stop, make a tally: face, movement, question, surprise or about-me. Which hook wins for you?
In a famous 1999 experiment, Daniel Simons and Christopher Chabris asked people to count basketball passes in a video. About half missed something big walking through the scene. Look up "inattentional blindness." What does it mean for someone watching a busy video or ad?
Six ways to say yes
In his 1984 book Influence, psychologist Robert Cialdini described six common principles of persuasion (in 2016 he added a seventh, unity). Ads, influencers and even your friends use them, often without thinking about it.
| Principle | The idea | Sounds like… |
|---|---|---|
| Reciprocity | We want to return favours. | "Here's a free sample!" |
| Commitment | Once we say yes to something small, we stick with it. | "Just sign up for the free trial." |
| Social proof | We copy what others seem to be doing. | "Everyone on your street has one." |
| Authority | We trust experts and people in uniforms. | "Recommended by coaches." |
| Liking | We say yes to people we like or relate to. | Your favourite creator, smiling. |
| Scarcity | Things seem more valuable when they're rare or ending. | "Only 3 left! Ends tonight!" |
"Dentist-approved. Thousands of Edmontonians already switched. Only 3 left at this price!"
(This ad is made up.) Notice it never says what the product does better.
Find three real ads (bus shelter, YouTube, a flyer, an influencer post). For each, write the product and which principles it uses.
Persuasion isn't automatically bad: a public health campaign persuades too. Where's the line? Write your own rule, then test it on one ad. Hint: is it true, and does it leave you free to choose?
Why outrage spreads
We share things that make us feel. Researchers have found that the type of feeling matters, not just whether it's positive or negative.
In a 2012 study of New York Times articles, Jonah Berger and Katherine Milkman found that stories causing high-energy emotions (awe, anger, anxiety) were more likely to be shared than ones causing low-energy emotions like sadness.
A 2017 study led by William Brady looked at posts on Twitter about political issues and found that posts using more moral-emotional words (like shame, evil, hate) tended to be reposted more. Later studies have questioned it, and only partly replicated it. Outrage often gets attention, and attention gets rewarded.
Imagine each person who sees an angry post shares it with 3 new people, who each share it with 3 more.
If a calmer post gets shared with only 2 each time: 2 + 4 + 8 + 16 + 32 = 62. Small differences multiply.
Rewrite this made-up headline so it's accurate but calm:
"City council DESTROYS skatepark plans in SHOCKING vote!!"
Before you share, ask: What am I feeling right now? Who gains if I share this? Is it true? Find one post in your feed that's designed to make people angry. Who might benefit from that anger?
The reward loop
Many apps seem to follow a loop like the one writer and consultant Nir Eyal described in his 2014 book Hooked: a trigger (a buzz, boredom), an action (open, scroll, refresh), a reward that's different every time, and an investment (you post or like, so you come back).
The key is the unpredictable reward. In the mid-1900s, B.F. Skinner found that animals rewarded unpredictably kept pressing a lever longer than ones rewarded every time. Some compare a feed to this (how far that holds is debated): the next scroll might be amazing.
About dopamine: you'll hear that apps give you "hits of dopamine." Dopamine is a brain chemical involved in motivation and in learning which actions lead to rewards. It's often oversimplified as a "pleasure chemical," and scientists are still studying how it works with screens, so be cautious of anyone who sounds too certain.
Sam picks up their phone 45 times a day and stays about 3 minutes each time.
Canada's 24-Hour Movement Guidelines suggest no more than 2 hours a day of recreational screen time for ages 5–17, and 3 for adults.
Tick the ones you'd actually try:
Suppose (made up) 1 in 8 refreshes shows something great. What's the chance that 8 refreshes in a row show nothing great? So what's the chance of at least one great thing?
Framing & bias
Framing is how information is presented. In a classic 1981 study, Amos Tversky and Daniel Kahneman showed people made different choices about the same outcome depending on whether it was described as lives saved or lives lost.
Made-up survey: 75 of 300 people skip breakfast.
All true. Each one feels different.
Five biases that media can use
| Confirmation | We notice and believe what fits what we already think. |
| Anchoring | The first number we see shapes our judgement ("Was $80!"). |
| Availability | Things we've seen a lot seem more common than they are. |
| Negativity | Bad news grabs us more than good news. |
| Bandwagon | We lean toward what seems popular. |
a. After watching shark videos, Lee thinks shark attacks are common. ____
b. Ava only clicks videos that agree with her opinion. ____
c. A hoodie "was $90, now $45" feels like a steal. ____
d. A song has a billion streams, so Jo decides it must be good. ____
A made-up headline says "Screen time soars 20%!" Write two more true headlines from the same fact: one that sounds calm, one that sounds positive. What extra information would you want before believing any of them?
Quick self-check
Six questions, covering every stop. Show your thinking. Answers are upside down at the bottom; no peeking till you're done.
1 · What is the name for hearing your own name across a noisy room?
2 · "Only 2 left in stock!" uses which persuasion principle?
3 · Name two high-energy emotions linked to more sharing.
4 · Why are unpredictable rewards hard to stop checking for?
5 · "90% fat-free" vs "contains 10% fat" is an example of what?
6 · You believe posts that agree with you and ignore ones that don't. Which bias?
Re-shade your knowledge meter
How much do you know about the psychology of media now? Flip back to p.3 and shade the meter again in pen (or shade this one). Did any of the four bricks on p.2 move from "Not yet" to "Got it"?
The 7-day habit experiment
Be the scientist and the subject. Track your own media use for a week, test one change, and share what you found as a one-page infographic.
1 · Track it
Days 1–2: change nothing, just track. Days 3–7: make your one change.
| Day | Screen time | Pickups | Mood 1–5 |
|---|---|---|---|
| 1 | |||
| 2 | |||
| 3 | |||
| 4 | |||
| 5 | |||
| 6 | |||
| 7 |
2 · My one change
Pick one habit hack from p.7 (or invent one).
3 · Predict
What do you think will happen?
4 · Share it as an infographic
- A chart of your 7 days (bar or line)
- Your change, your prediction and what actually happened
- One honest sentence about how it felt
- Made-up or real? Say so: these are your numbers
5 · Sketch the infographic
Keep it kind: this is about noticing, not judging yourself. Use your phone's built-in screen-time tool or a tally. Your data is yours; share it only if you want to.
