We give a numerical analysis of long-wavelength modes in the WKB approximation of cosmological scalar fields coupled to gravity via ξϕ²R. Massless fields are coupled conformally at ξ=1/6. Conformality can be preserved for fields of nonzero mass by shifting ξ. We discuss implications for density perturbations.
