  We study the nonlinear rheology of a glass-forming binary mixture under the
reversal of shear flow using molecular dynamics simulations and a schematic
model of the mode-coupling theory of the glass transition (MCT). Memory effects
lead to a history-dependent response, as exemplified by the vanishing of a
stress-overshoot phenomenon in the stress--strain curves of the sheared liquid,
and a change in the apparent elastic coefficients around states with zero
stress. We investigate the various retarded contributions to the stress
response at a given time schematically within MCT. The connection of this
macroscopic response to single-particle motion is demonstrated using
molecular-dynamics simulation.
