The difficulty in verbally expressing emotions, the lack of imagination and the colorless communicative style that Sifneos and Nemiah indicated with the term "alexithymia" in 1970, has led in the last 40 years to different lines of research. The seminar intends to deal with the alexithymic construct in the light of new research which underlines that it no longer refers exclusively to the psychosomatic patient; alexithymic areas or moments can in fact be found in different personality organizations, in relation to different contexts and moments of life.
