Among the most common metaphors are many those that refer to our senses of taste, hearing, touch, sight and smell. They create some pictures in our cognition in order to signify some concepts. They are called visual metaphors. English language tends to use visual metaphors to represent thought processes. For example, English speaker asks if others "see" what he means, he speaks of understanding things "in a different light" or from another's "perspective" or "point of view," he “grasps” a concept, he "revises" (see anew) "research" that he has done in various "fields" of "s study" and he “lights up” the reason and so on.
In each case, an abstract cognitive process is being spoken of or is thought of, as if it were a visual one. Such types of metaphors shape the way of our thinking. Firstly, it shapes our thinking because it makes it more creative. Secondly, it helps to create in our mind some images that are associated with cognitive process and it gives us the opportunity to consider them as things that we can observe. In other words, such metaphors make cognitive process more real. For example, I “see” what you mean – I can see you thought that it is why I understand you - we consider the mental process as something real that we can observe. I understand you – the word “understand” does not form in our consciousness any image. Finally, metaphors always have a great impact on our thinking, because we use them every day and through their influence, we consider almost every process, thing and feeling in our world.
To sum up, many different metaphors indicate thought processes. They make us consider them as visual ones. Due to it, they have a great impact on the way we think and give us the opportunity to view mental processes in a little bit different way than we consider them in speech without such metaphors.
