Mixed Methods and Behavioural Science
Summary
In this insightful session, Mike, an expert in behavioral research with over eight years of experience and currently pursuing a PhD, explored the application of mixed methods research enhanced by behavioral science and biometric tools such as eye tracking, EEG, and facial expression analysis. He explained the necessity of combining qualitative insights with quantitative data to understand both what users do and why, especially beyond conscious awareness, addressing subconscious motivations that affect behavior. Mike detailed how attention, emotion, cognitive load, and motivation impact user experience on websites, highlighting metrics like fixation count, pupil dilation, prefrontal asymmetry, and valence in facial coding. He illustrated these concepts through real examples, such as analyzing hotel landing pages and checkout processes, emphasizing that simplified tasks increase adoption while motivating users improves engagement. Mike also discussed the ethical considerations of behavioral science research and the importance of pre-screening for neurodiversity and cultural differences. The session concluded with practical advice on designing, testing, and iterating experiments to maximize conversion and optimize user experience, underlining the power of triangulating data from various sources to build actionable hypotheses and validate them in real-world settings. The talk was moderated by Paula and featured engagement with attendees through detailed Q&A, including questions on cognitive load measurement and accommodating neurodiverse users.
Key Insights
-
•
Mixed methods research blending qualitative and quantitative data delivers deeper understanding of both observable behavior and underlying motivations.
-
•
Eye tracking combined with EEG and facial expression analysis can reveal subconscious attention, emotional valence, and motivation shifts during user interaction.
-
•
Increased pupil dilation indicates arousal or heightened attention, while prefrontal asymmetry changes correlate with approach or avoidance motivation.
-
•
Users often fixate first on salient elements, but repeated revisits to specific content indicate genuine interest and engagement.
-
•
Websites lacking sufficient visual content, like images on hotel landing pages, are perceived as less trustworthy and inviting.
-
•
Cognitive load increases when users struggle with tasks, detectable via metrics like blink rate reduction and EEG signals.
-
•
Simplifying tasks and motivating users are the two primary levers to improve behavior and conversion on digital platforms.
-
•
Behavioral science-based experiments can identify friction points contributing to drop-offs, enabling targeted design improvements.
-
•
Ethical considerations, including screening for neurodiversity and disability, are crucial when applying biometric behavioral research.
-
•
Triangulating lab-based biometric insights with real-world analytics and user feedback allows building testable, effective UX hypotheses.
Notable Quotes
"Marketing is psychology. There’s very little difference between the two because to sell, you need to know how people think and feel."
"People don’t remember what you said to them, but they remember how you made them feel."
"Eye tracking first fixation shows what’s salient, but repeated fixation and revisit counts tell you what truly interests users."
"The part of the brain we’re aware of is like the press release office; the real decisions happen behind closed doors."
"If a website is hard to use, motivation and approach drops, and users are less likely to engage or convert."
"Facial coding AI can’t tell if a smile is real or if someone is uncomfortable; human observation remains crucial."
"The simpler a behavior or task is, the more likely people are to adopt it on websites or in marketing."
"Using a mixture of behavioral science, analytics, and experiments helps prioritize changes that truly move KPIs."
"When people start saying a page looks busy or cluttered, it's a strong shorthand indicating cognitive overload."
"Once you find a behavioral experiment that works, it’s like playing Minesweeper—you place bets based on current knowledge to uncover more."
