    KEY POINTS

  1. Cognition comprises many processes, including thinking,
    attention, learning, memory, perception, decision-making,
    planning, reading, speaking, and listening.
  2. The way an interface is designed can greatly affect how well
    people can perceive, attend, learn, and remember how to carry out
    their tasks.
  3. The main benefits of conceptual frameworks and cognitive
    theories are that they can explain user interaction and predict
    user performance. . The conceptual framework of mental models
    provides a way of conceptualizing the user’s understanding of the
    system.
  4. Research findings and theories from cognitive psychology need
    to be carefully reinterpreted in the context of interaction
    design to avoid oversimplification and misapplication.
