In this paper we discuss the notions of pseudo-contractibility and weak contractibility on hyperspaces of (Hausdorff) continua. Also we prove that if a continuum X contains an Ri-set then it is not pseudo-contractible. As a consequence we have that the existence of an Ri-set in a continuum X implies non(pseudo)-contractibility of some hyperspaces
