The Design Psychologist | Psychology for UX, Product, Service, Instructional, Interior, and Game Designers – Details, episodes & analysis

This episode is an absolute masterclass in human-centered design, featuring Dr. John Whalen—cognitive scientist, seasoned UX expert, and author of Design for How People Think.

John introduces us to his powerful framework, The Six Minds of UX, which breaks down the complexity of user experience into six distinct cognitive lenses. Whether you’re designing a website, app, service, or physical product, these six minds offer a foolproof checklist to make sure you’re not leaving any critical piece of the human experience behind.

In this episode, we explore:

• What exactly the Six Minds are, and why they matter
• How each mind maps to how people think, feel, and behave
• Real-world stories—from Google Scholar to voice interfaces—showing how the framework drives better design
• The role of expectations, emotion, and memory in digital product success
• How AI is shifting the game for user research and what the future researcher might look like

We also dive into some exciting stuff around synthetic users and dynamic personalization.

If you’ve ever wondered how to make your design work not just beautifully but intelligently, this episode is for you.

What does the color of your brand really say about your business? Is there truth behind the popular color psychology charts? In this episode, we cut through the noise and explore the actual science behind color psychology—what it tells us, what it doesn't, and what that means for your branding decisions.

We’ll explore:

• Why some color associations (like “blue = trust”) persist—and whether they hold up under scrutiny
• The surprising cultural roots behind color meanings (hint: pink wasn’t always for girls)
• The science of how color affects our emotions—and where it doesn’t
• What neuroscience reveals about how we really make buying decisions
• Why brand success is about more than just picking the “right” color

You’ll leave this episode with a clear, evidence-based understanding of how to think about color in your brand. 

By the end, you’ll know how to move beyond generic color charts and toward smarter, science-backed design choices.

Today on The Design Psychologist, we're diving deep into the intersection of psychology and design with none other than Susan Weinschenk, PhD—the person you’ll literally find next to the term “design psychologist” in the dictionary.  Susan is a pioneer in applying behavioral science to UX and product design, and the author of essential books like How to Get People to Do Stuff and 100 Things Every Designer Needs to Know About People. 

In this conversation, we explore Susan's journey from psychology to design, how human factors evolved into today’s UX, and why understanding the three parts of the brain is crucial for anyone building products. 

You’ll also hear us unpack:

• Why emotional and unconscious processing drives most user behavior
•  Why dopamine isn't about pleasure—but about anticipation
• What most designers get wrong about memory and readability
• The neuroscience of storytelling and why it matters for websites, apps, and products
• The psychology behind gamification—and what truly motivates users
• Why stories are essential in product and communication design
•  Why every UX decision should start with a “micro-moment”

Imagine dragging a jammed suitcase through a crowded airport—frustrating, right? Now imagine that same experience happening in your app, your website, or your product design. That’s performance load: the hidden mental and physical effort users endure when your design isn’t working for them.

In this episode, we take our first step into the world of design psychology by exploring the concept of performance load. You’ll learn how cluttered interfaces, too many clicks, and confusing layouts quietly pile up work on your users. And more importantly, you’ll discover how small design shifts can reduce friction and create smoother, more delightful experiences.

You’ll learn:

• What “performance load” really means—and why it matters
• The four types of load: visual, intellectual, memory, and motor
• How to spot friction in your designs before it frustrates your users
• How real organizations like NASA and Dropbox design for ease
• When simplifying a task helps—and when it hurts (especially in education)

By the end of this episode, you’ll see your design not just as a tool, but as a bridge between humans and their goals—and you’ll know how to make that bridge a whole lot easier to cross.

In this teaser episode, host Thomas Watkins introduces The Design Psychologist—a podcast where human behavior meets design. Thomas shares what inspired him to bridge the gap between psychology and design, outlines what listeners can expect in future episodes, and invites you to explore how design shapes our thoughts, emotions, and actions. Whether you're a designer, psychologist, or curious thinker, this show is your gateway into the minds behind meaningful design. 

How do you figure out what features to build into your design?
How do you get those magical insights that actually improve your product—versus just shifting things around?

In this episode, we unpack one key distinction that helps design psychologists and UX researchers choose the right method at the right time: inductive vs. deductive research.

Imagine you have two different ideas for how to design an app for restaurant waitstaff. You think of adding some possible features, like a picture-based layout, or a list of incoming customers.

 So—do you give the waitstaff a prototype of each app version and see which version performs better (deductive research)? Or do you systematically observe the actual waitstaff in action before even deciding which features to build (inductive)?

This choice is about more than methodology—it shapes the kinds of insights you get, and how impactful your design ultimately becomes.

🔍 You’ll learn:

• When inductive research unlocks hidden insights you didn’t even know to look for
• Why deductive research is great for making clear decisions—fast
• How your design phase should guide your research method
• What to consider when you're short on time or budget
• And how to avoid a common trap: testing too early

By the end, you’ll know how to orient your research approach based on where you are in the design journey—so you can uncover insights that actually move the needle.

In this episode, Thomas interviews Dr. Chris Wickens, a pioneer in cognitive engineering and human factors, and they discuss how designers can reduce errors and enhance decision-making when lives are on the line. They delve into the high-stakes world of design psychology for critical environments—think operating rooms, airplane cockpits, and military control systems. 

Together, they explore the real science of attention, what causes overload and confusion in high-pressure moments, and how augmented reality could revolutionize user interfaces in critical settings. Whether you're designing for surgeons, pilots, or autonomous vehicles, this episode is packed with essential takeaways from decades of research in applied cognitive science.

🔍 In This Episode, You’ll Learn:

• What every designer should know about how human attention actually works
  
  
  
• Why traditional design approaches often fail in high-pressure contexts
  
  
  
• How to reduce cognitive load and prevent life-threatening mistakes
  
  
  
• The surprising ways augmented reality is shaping the future of human-machine interaction
  
  
  
• Lessons from the deep history of human factors and applied psychology

Why do some products feel natural the moment you touch them—while others are baffling from the start? 

In this episode, we explore the psychology of affordances—those subtle cues that tell us what to do next, without saying a word. From door handles to digital apps, we break down how great design speaks directly to human intuition.

You’ll learn:

• The psychological principles that make interfaces feel “just right”
  
  
  
• What Don Norman meant by affordances, signifiers, and anti-affordances
  
  
  
• How to avoid common design traps that confuse users
  
  
  
• Real-world examples that reveal the power of creating an intuitive user experience
  
  

By the end of this episode, you’ll start seeing design in a whole new way—and be ready to create products that people instantly understand.

In this episode of The Design Psychologist, we dive deep into the world of qualitative research and human-centered design with legendary UX thinker Indi Young. 

If you've ever felt like your user interviews only skim the surface—or if you've relied too heavily on personas—you might be missing the most powerful insights. Indi joins us to explore how deep, non-judgmental listening can revolutionize your understanding of users and, ultimately, your design outcomes. 

Together, we tackle questions like:

• What is deep listening, and why is it essential in design research? 
• Why do traditional interviews often fail to uncover what truly drives user behavior? 
• What are thinking styles, and how are they more effective than personas? 
• How can designers move from interpreting behavior to understanding internal reasoning? 

By the end of this episode, you’ll see user research—and your role as a designer—through a completely new lens. You'll be equipped to listen more deeply, think more critically, and create more human-centered solutions.

How many participants do you need to test in order to make valid research claims? In this episode, we dive deep into the science and psychology behind sample sizes in user testing. Whether you're working with five users or five hundred, the number you choose can shape the story your research tells—and how credible your findings appear to stakeholders.

• Why sample size is one of the most misunderstood elements in product research
• The psychological impact of “too few” vs. “just enough” users in high-stakes design reviews
• Whether the popular idea that "you only need to test five users" is a myth or a useful research guideline
• How to determine the right number of participants based on your research goals

By the end of this episode, you’ll have a clearer, more confident approach to choosing sample sizes. This will help you create better, more intuitive, and scientifically sound designs.
