We utilize the angle and momentum resolution of our apparatus to study the polarization of 375 GeV/{ital c} {Sigma}{sup +} hyperons produced by 800 GeV/{ital c} protons incident on a Cu target. By examining in detail two of our high statistics data samples, we find evidence for structure in the {ital p}{sub {ital t}} dependence of {Sigma}{sup +} polarization and are able to extract the {ital x}{sub {ital F}} dependence of the {Sigma}{sup +} polarization and compare it with {ital x}{sub {ital F}} behavior in the {Lambda}{sup 0} and {Xi}{sup {minus}} systems.
