The study of the longitudinal polarization of $\Lambda$ and $\overline{\Lambda}$ hyperons produced in polarized deep inelastic scattering, neutrino scattering, and in Z0 decays allows one to access the spin dynamics of the quark fragmentation process. Different phenomenological spin transfer mechanisms are considered and predictions for the $\Lambda$ and $\overline{\Lambda}$ longitudinal polarization in various processes using unpolarized and polarized targets are made. Current and future semi-inclusive deep inelastic scattering experiments will soon provide accurate enough data to study these phenomena and distinguish between various models for the spin transfer mechanisms.
