Then, proposals of more objective and understandable definitions and explanations of controversy cognitive concepts like consciousness are given. This is a proposal for a solution to many historical cognitive science controversies, and the main argument that pattern recognition is also a sufficient cognitive science principle. 

As any candidate as a complete theory of cognitive science, this model allow us to re-discuss the philosophy and foundations of science and the human understanding of the universe. With the promising applied pattern recognition technology already in development, this model could help to give some directions to artificial intelligence and also neurobiology and psychology-sociology research. 

## 2. Pattern Recognition Is A Necessary Cognitive Science Principle

Pattern Recognition is already established as a necessary concept to understand the mind functioning. No scientific study denies that a wide range of cognitive phenomena like detection, perception or sensing are intimately related to pattern recognition processing. Also, intense research in pattern recognition processing in biological, neural, artificial and computational cognitive systems are actually one promising front end of science and technology. But no cognitive science model discuss formally the pattern recognition concept as a general and fundamental cognitive science principle. Such approach is of fundamental importance since pattern recognition processing is one of the mechanisms of mind functioning most observed experimentally. Since actually there is no other technique, formalism or model in the cognitive science that can substitute the pattern recognition functionality, this is a proposed proof that pattern recognition is a necessary and fundamental cognitive science principle. 

## 3. Pattern Recognition Can Be A Sufficient Cognitive Science Principle

It is generally accepted that pattern recognition can explain sensorial and perceptual cognitive functions, but it is not the same for more controversial cognitive functions like consciousness. This paper argues that the same pattern recognition mechanisms can perform instinctive, processing, learning and acting functions. Then it is shown that with a pattern recognition cognitive science formalism we can build definitions an explanations of any controversial cognitive function as consciousness, with an understandable description. With an objective formalism it is possible to propose qualitative and quantitative cognitive science models to be experimentally tested. 

All this allows in this paper to claim that pattern recognition can be a sufficient principle to cognitive science. 

## 4. Physical And Cognitive Concept Of Pattern Recognition

The concept of pattern recognition is widely used in cognitive science related areas. It is generically defined in Math, Computer Science, Design, and few other areas as a method or technique of classification, regularity search, etc. But the formal overall concept of pattern recognition from physical to algorithmic basis is not clear, coherent or unambiguously defined in the scientific literature [Verhagen 1975], [Jie Liu, Jigui Sun, and Shengsheng Wang 2006]. 

Here is proposed some definitions of pattern recognition first as a general physical phenomenon. This is important because pattern recognition is frequently viewed as an artificial technique rather than a basic natural phenomena. Then is derived
