Understanding Psychology in UX Design and Research

Introduction

  • Speaker: Ash Montes, Freelance UX Researcher
  • Focus: Importance of psychology concepts in UX design and research.
  • Resources will be shared at the end.

Mental Models

  • Definition: Mental models are what people believe about how things work.
  • Importance: Essential for understanding user expectations.
  • Example: Users expect search bars to be at the top of e-commerce websites due to previous experiences.
  • Consequence of Overlooking: A mismatch between the designer's mental model and the user's can lead to design errors and usability issues.

Case Study: iPhone Launch

  • Users unfamiliar with iPhone's home button could not find it easily due to its discreet design.
  • Even if information is provided, it may not be perceived correctly by new users.

Selective Attention

  • Explanation: Users may miss obvious information based on how it is presented.
  • Example: The "gorilla test" where participants missed a person in a gorilla costume due to focus on basketball passes.
  • Implication: Designers must consider how information is prioritized in design.

Cognitive Overload

  • Users crave information but can only process a limited amount at a time.
  • Understanding this can help anticipate user behavior during research.

Differences Between What People Say and Think

  • Introspection Illusion: People believe they understand their emotions better than they do.
  • Example: Choice Blindness experiment shows that people can rationalize choices they did not make.
  • Implication: Feedback may not accurately reflect true preferences or behaviors.

Cognitive Bias in UX Research

  • Definition: Bias involves shortcuts in decision-making that can lead to errors.
  • Examples of Biases:
    • Social Desirability Bias: People may provide socially acceptable answers rather than true ones, e.g., regarding eating habits.
    • Hawthorne Effect: Productivity may increase simply because participants know they are being observed.

Participant Behavior in Usability Testing

  • Participants may give biased positive feedback due to discomfort.
  • Importance of creating a comfortable environment for honest feedback.
  • Recommendation: If actions (behavior) and words (feedback) do not match, prioritize actions.

  • Learning psychology enhances understanding of user behaviors and improves UX design and research outcomes.
