The purpose of this article is to emphasize the importance of multi, inter and transdisciplinarity, in the emergence and evolution of various sciences, especially in the field of experimental psychology. Some of the contributions of two great Romanian scientists to the development of psychology as a science are brought to the forefront, namely: the “structural system of temperaments” put forth by Gheorghe Zapan and the “consonantist psychology”, introduced by Ştefan Odobleja, in which he used, for the first time, the concept of “reverse connection”, later known as feed-back.
