Vortex motion in high temperature superconductors is studied starting from a variant of the time dependent Ginzberg Landau(TDGL) equations,in which the order parameter relaxation time is taken to be complex.Using Lawrence Doniach model and considering a TDGL model modified to take into account the Hall effect, we have evaluated and discussed the sign change of the Hall angle and anomalous Hall effect.The results are discussed in light of rather puzzling sign change of the Hall effect which has been observed in the mixed state of the high temperature Superconductors.
