Let R be a commutative Noetherian ring with non-zero identity, a an ideal of R and M,N two R-modules. The main purpose of this paper is to study the circumstances under which, for fixed integers j in N_0 and n in N, the R-modules Ext^j_R(N,H^n_a(M)) and Tor^R_j(N,H^n_a(M)) are weakly Laskerian or Matlis reflexive. In this way, we also get to some results about the associated primes, coassociated primes and Bass numbers of H^n_a(M).
