  1. How to do UX research like a psychologist (or why

    we should hire one) Khoa D. Le Nguyen PhD. Candidate in Psychology at UNC-CH Interim Behavioral Science Manager at WW (Weight Watchers)
  2. UNC WW • Research how people experience positive social connection

    and why it matters • Research behavior change to inform app design • Democratize behavioral science in design • Offer training in quantitative research
  3. UX Research • Often atheoretical • Often qualitative methods •

    Rich picture of users Users needs, motivation, and behavior Behavioral Science / Psychology • Theory-based • Often quantitative method • Detect statistical relationship that may not be noticeable How to make UXR even better? +
  4. 1. Before a project, do a literature search* • Save

    time and research effort • Use evidence and framework to inform our research *when appropriate
  5. E.g. How many program choices to present? • Optimal number

    of choice: 8 - 14 • Decision difficulty (e.g. time pressure) • Choice set complexity • Decision goals: browsing vs. choosing
  6. 2. Adopt validated measures and questionnaires from the research literature

    Why? • Save time • These measures are well-defined, valid, and reliable • Can target hidden psychological tendencies (e.g. sexism, racism)

    users stick to exercising? • Instead of / in addition to asking users what strategies are effective for them...
  10. Takeaways We can effectively gain better insights about users by

    integrating approaches from psychology & behavioral science • Do a quick literature search and use theoretical framework to guide research & design • Use validated measures & questions • Use quantitative method & inferential statistics to reveal hidden relationships
