Mathematical Psychology actually focuses on process models of perceptual, cognitive and motor processes as inferred from the ‘average individual’. It is the study of behavior through a mathematical lens. It was almost exclusively focuses on the modeling of data obtained from experimental paradigms and is therefore even more closely related to experimental psychology/cognitive psychology/psychonomics. It is a sub-field of psychology that started in the 1950s and has continued to grow as an important contributor to formal psychological theory.
