A conclusion we can propose is that **the learning concept is a subset of the** 
pattern recognition concept. 

## 5. Pattern Recognition Definitions And Explanation Of Cognitive Phenomena

The above physical to cognitive definitions and discussions are a formal basis to propose a general theory for cognitive science in the following steps: 
- Describing instincts as pattern recognition functional mechanism. - Proposing an unsupervised instinctive conditioned pattern leaning model. - Proposing pattern recognition definitions and explanation mechanisms of any higher order cognitive concepts as thinking and consciousness. 

- Applications proposals. 

## 5.1. Instincts, Sensing, Feelings And Emotions - Basic Cognitive Phenomena

The basic animals instincts concept can be proposed to be functionally isomorphic to the pattern recognition concept, and pattern recognition mechanisms as proposed here can be a mechanistic description of any instinctive related cognitive function. 

As far as the patterns, or set of properties, of one or a set of instincts can be described, a pattern recognition processing can be proposed as a functional mechanism. A simplified proposed description follows. 

Basic instincts as pain, fear, desire, surprise, etc, can be described as predominantly built in pattern recognition functions that are relatively independent from learning and can have a great influence or even dominate the overall pattern processing at a period of time. The expression predominantly built in was used assuming that most biological instincts are considered mainly biological basic functions with less influence from phenotype learning, even some instincts seems able to learn to react somehow differently as for pain tolerance training, learned traumas, etc. 

A simple explanation to the biological instinct mechanisms can be analogous to an artificial pattern recognition processing by establishing some previous categories of instinct activation patterns like: 
Action Instincts - "DO A" activation patterns - when a pattern or a set of patterns are preprogrammed to be active at periods of time, performing an analogous role of computer "processing clock" functions. The neural analogous can be sets of neurons which fires synapses periodically without any previous stimulation, playing the role of "neural system clock". These independent neural activations can be due to any neural or body metabolism or structure, being less dependent on the synaptic mechanisms as a source, but then doing standard synaptic role as an input pattern in the pattern recognition mechanism. Possible biological "DO A" instincts are sleeping, awaking, hungry, compulsive or involuntary muscle motion, and even a explanatory basis for attention, will, desire and others cognitive functions. 

Reaction Instincts - "IF A THEN B" activation patterns - when a reaction to a category of activated input or initial patterns have a predefined response or processing pattern. The computational analogous can be any set of predefined instructions for a input pattern category. Possible neural analogous can be any predefined reaction from stimulus like pain reactions, scare reactions, reflex, etc.
