Kitab Al Manazir : The pioneering role of Ibn Al-Haytham to the development of Psychophysics

Auther : Omar Khaleefa

The study attempted a psychological reading of Kitab Al-Manazir, or Optics by Ibn Al-Haytham. The primary source for this study has been published by the National Council for Culture, Arts, and Letters in Kuwait, and edited by Abdelhamid Sabra (1983). The book consists of three maqala or essays, Maqala 1, entitled On vision in general introduces the complete theory of vision in which Ibn Al-Haytham contradicts previous studies. Maqala 2, is entitled On the properties perceived by sight, their causes and manner of their perception. Maqala 3 is entitled On the errors of direct vision and their causes. In maqala 2, and 3, Ibn Al-Haytham examined the psychology of vision and psychophysics. Ibn Al-Haythams theory of vision is not only unique but is also based on a new scientific method he puts its foundations and not associated with previous ones. His theory of vision is composed of multidisciplines such as physics, mathematics, and geometry. In addtion, Ibn Al-Haytham made the first experimental attempt to design an apparatus for measuring the errors of vision, or what in modern psychology may be called visual illusion, and in physics visual aberration. Historiographical Investigation in sciences shows that no complete theoretical and experimental contribution was made on the psychology of vision and psychophysics before Ibn Al-Haythams study. As a consequence, this original experimental contribution directs our attention to the fact that the history of psychology needs to be re-written. If our investigation is proved to be true, the present study introduced a new chronological statement that the first half of the eleventh century not the nineteenth century was the earliest known starting point of experimentation in psychology. In addition, this study asserts that Fechner was not the pioneer of psychophysics in his book Elements of psychophysics, but rather that Ibn Al-Haytham preceded such work in his Kitab Al-Manazir or Optics.
