The implementation of most of the ideas of the research program presented here has been carried out in collaboration with Marina Augusto, whose syntactic expertise has been crucial for them to take their present form. A number of research students have also been indispensable for the development of some of them. Possible misconceptions in the way they are presented in the present text are, in any case, my own fault. I would like to thank Mercedes Marcilese for her help in the final review and references. ** E-mail: [email protected]. 214<Avances en Psicología Latinoamericana/Bogotá (Colombia)/Vol. 29(2)/pp. 214-230/2011/ISSN1794-4724-ISSNe2145-4515 Letícia M.
