This course provides an overview of how empirical findings and methods from cognitive psychology can be applied to the design of interfaces, objects, and environments. Students will review how theories of human perception, cognition, and interaction have informed human factors and ergonomics, and how attention to the psychology of individual capacities along with environmental and social factors can inform design. They will also encounter widely used lab and field research methods, including task analysis, usability testing, experimental design, and observational and self-report measures of users’ experience, cognition and affect. Throughout, critical questions about the ethical treatment of humans—both research participants in the design process and the eventual users of what is being designed—and about broader social impacts will be addressed. At least one prior core course in psychology is a prerequisite, with coursework in cognition, perception or language particularly helpful.
