UX practitioners make dozens of daily decisions that should be based on psychological principles. Unfortunately, many practitioners have not taken university-level courses on these topics. They pick up information along the way, but it is hard to discriminate the signal from the noise. This problem is especially acute in healthcare, where the quality of a patient’s care may be influenced by your design. In fact, your design may even influence a patient’s decision to seek healthcare or not. Based on award winning classes in Design Psychology from two large universities, the author will introduce Design Psychology Principles related to: • Sensation and perception (vision, hearing, Gestalt perceptual grouping) • Cognition (learning, memory, decision making, judgment, problem solving) • Social behavior (team cognition) • Culture • Emotion (designing for and eliciting appropriate affect). After class you will make more informed, defensible, and confident design decisions.
