ACT Theory

 

The ACT is a cognition theory developed by John R. Anderson an American Psychologist. He was born in 1947 in Vancouver, British Columbia. He was well known as Cognition Architect as he had expertized in Cognitive Psychology.

Theory:-

This theory talked about the tasks performed by Human Beings. Each and every task performed by humans are considered several steps and process. This model provides a framework of the process that happens in our mind during the time of our activities. This framework may look like a programming language. ACT theory is basically inspired by the work of Allen Newell.

ACT-R, Adaptive Concept of thought-Rational is based on the assumption that human knowledge can be divided into two kinds of representations first is Declarative and second is Procedural. ACT-R is a cognitive architecture. Cognition is the process of understanding and acquiring knowledge through thought. The ACT architecture made up of framework or model.

The main components of the ACT are:-

  1. Modules- there are two types of modules:-
  • Perceptual motor module- it intersects with the real or outer world. It may take care of the inferences.
  • Memory module- these are of three kinds
  1. Procedural memory:- this is the memory we generally use in simple things such as removing the pen cap.
  2. Declarative memory:- this is a kind of memory consists of facts and information regarding something. Such as minutes in one hour.
  3. Working memory:- it is a long term memory which highly activated.

  1. Buffers- the buffer system provides accessibility to cognitive adaptations thoughts.
  2. Pattern Matcherit attempt for the production that matches current state of buffer. These productions work for a specific period of time and later they alter the buffer and changes occurred in the system. This is also why ACT also explains as s production system. Every human task can be made on this task. The model of each person is different that’s why it also performs or thought differently. This model helps to find out quantitative measures. This theory finds out perception and attention, problem-solving and decision making, language and communication, individual difference between persons.
