Question

How does psychological design rationale help in improving the design of interactive systems over time?

a.

By documenting the designer's intention in building the artifact.

b.

By providing empirical observations of users' work tasks.

c.

By capturing the natural evolution of user tasks and the artifact.

d.

By structuring the design space to represent various design alternatives.

Answer: (c).By capturing the natural evolution of user tasks and the artifact. Explanation:Psychological design rationale helps in improving the design of interactive systems over time by capturing the natural evolution of user tasks and the artifact, allowing consequences of one design to be used to improve later designs.
