ACT – R (Adaptive Control of Thought - Rational) by John Anderson
I. Objectives
At the end of the module, the students are expected to:
a. define ACT – R;
b. apply the ACT – R Theory in learning; and
c. appreciate the importance of ACT – R in learning
II. Introduction of the Topic
ACT-R (Adaptive Control of Thought--Rational) is a cognitive architecture mainly developed by John Robert Anderson at Carnegie Mellon University, which is also a theory about how human cognition works. Most of the ACT-R basic assumptions are also inspired by the progresses of cognitive neuroscience, and, in fact, ACT-R can be seen and described as a way of specifying how the brain itself is organized in a way that enables individual processing modules to produce cognition. Researchers working on ACT-R strive to understand how people organize knowledge and produce intelligent behavior. As the research continues, ACT-R evolves ever closer into a system which can perform the full range of human cognitive tasks: capturing in great detail the way we perceive, think about, and act on the world.
ACT-R has been used successfully to create models in domains such as:
Learning and Memory; Higher level cognition, Problem solving and Decision making; Natural language, including syntactic parsing, semantic processing and language generation; and Perception and Attention.
III. Background of the Proponent
John Anderson was born in Vancouver, British Columbia, in 1947 and grew up in a poor section of the city. During his childhood he pursued a number of different dreams and he remembers his parents as supportful of them all. He went to the University of British Columbia dreaming of being a writer and left with the dream of practicing psychology as a precise and quantitative science. He went through a number of academic struggles reflecting his poor preparation and conflicting dreams. However, he managed to pull it all together and graduate at the
