  Theories beyond the standard model such as string theory motivate low energy
effective field theories with several scalar fields which are not only coupled
through a potential but also through their kinetic terms. For such theories we
derive the general formulae for the running of the spectral indices for the
adiabatic, isocurvature and correlation spectra in the case of two field
inflation. We also compute the expected non-Gaussianity in such models for
specific forms of the potentials. We find that the coupling has little impact
on the level of non-Gaussianity during inflation.
