We consider the various spin-spin effects in the processes e/sup +/e/sup -/..-->..chi-tilde/sub i//sup 0/chi-tilde/sub j//sup 0/ and e/sup +/e/sup -/..-->..chi-tilde/sub i//sup +/chi-tilde/sub j//sup -/ at Stanford Linear Collider (SLC) energies, where chi-tilde/sub j//sup 0/ and chi-tilde/sub j//sup +- / are gauge-Higgs fermions associated with the (minimal) supersymmetric extension of the standard SU/sub 3//sup c/ x SU/sub 2//sub L/ x U/sub 1/ model and are understood to decay in model-dependent ways. We argue that such effects may very well be visible at SLC (and CERN LEP) energies. We give a general theoretical apparatus for discussing these effects and assessing their various manifestations. We work out some illustrative examples of such manifestations.
