ABSTRACT
Recent years saw the development of a number of comprehensive theories of human cognition termed cognitive architectures that start to have an increasing impact on cognitive modelling applied to research questions in human-computer interaction (HCI). In this paper we discuss the concept of a cognitive architecture and illustrate it with Act-R/Pm, an especially interesting candidate from the viewpoint of Hci. We argue that cognitive architectures can go beyond providing mere scientific explanations of laboratory phenomena to providing usability predictions of real-world systems. After presenting some signature applications of architectures in Hci domains to support our claim, we discuss possible benefits and perspectives of architectures as a theoretical foundation for Hci.
