René Zazzo

René Zazzo (27 October 1910 – 20 September 1995) was a French psychologist and pedagogue.

Zazzo's research focused on child psychology. He was one of the first people to study a group of problems relating to dyslexia and disability. Considering the development of children considered to be weak, Zazzo proposed the concept of "oligophrenic heterochrony" in order to show that this development, compared with that of normal children, occurred at various speeds, according to the particular psychobiological sector concerned. The majority of research which Zazzo produced between 1950 and 1980 centered on what he regarded as "the principal problem of psychology"—that of the identity: how does a person's psyche build itself? The fields in which he worked were various attempts to bring answers to this question. Provided by Wikipedia
