Cognitive science research has influenced the applied science of human-computer interaction (HCI) in several ways:
1) It has provided insights into how humans process information and make decisions, which has informed the design of user-friendly interfaces.
2) Research on topics like perception, memory, and problem-solving has helped interface designers create intuitive systems that are easy for users to understand and learn.
3) By applying findings on cognition, HCI research has also contributed to areas like education technology and made the internet a more effective learning tool.
