Fundamentals of Human Behavior --- Surveys basic principles of cognitive and social psychology relevant to the design and use of information systems. Focuses on important findings in psychological science and their implications for the design and use of information systems. Topics include the basics of human perception, memory capacity and organization, the development of skill and expertise, and the characteristics of everyday reasoning and decision making. For example, a central problem in information science is how to label information stored for later recall. By examining how human memory operates, we can gain some insight into possible schemes that may be compatible with human users. This survey of what we know about the human mind offers ideas about how to exploit mental capacities in the design and use of information systems.
