We discuss the hadronic mass shifts of the lightest baryons generated by coupled-channel effects. The contributions from different thresholds are assumed to be related by SU(6)W symmetry. Using very general arguments, we derive mass formulas for the relative splittings of Δ-N, Σ*-Σ-Λ, and Ξ*-Ξ, which are satisfied by experiment to within 20%.
