ABSTRACT
This chapter analyses human intuitive static 4D concepts as mental imagery and tries to formulate them as spatial change events in mental image description language. Mental image directed semantic theory gives the definition of ‘between’ in a simple and language-free formula. In mental image directed semantic theory, dynamic 4D and static 4D events respectively correspond with temporal change events and spatial change events in Physical location, discriminated by the pattern parameter in mental image description language. There are two major hypotheses assumed on mental image. One is that mental image is in one-to-one correspondence with movement of the focus of attention of the observer. The other is that it is not one-to-one reflection of the real world. It is well known that people perceive more than reality. Mental image directed semantic theory employs an imaginary object called imaginary space region in order to formalize mental image systematically.
