Thinking is a higher cognitive function and the analysis of thinking processes is part of cognitive psychology

The basic mechanics of the human brain cells reflect a process of pattern matching or rather recognition . In a "moment of reflection", new situations and new experiences are judged against recalled ones and judgements are made. In order to make these judgements, the intellect maintains present experience and sorts relevant past experience. It does this while keeping present and past experience distinct and separate. The intellect can mix, match, merge, sift, and sort concepts, perceptions, and experience. This process is called reasoning. Logic is the science of reasoning. The awareness of this process of reasoning is access consciousness
