We have measured the temperature dependences of the various elastic constants of rare earth hexaborides. The characteristic features of the electron-strain interaction relating to the cooperative Jahn-Teller effect of PrB6, NdB6, DyB6, the Kondo effect of CexLa1-xB6 and the valence fluctuating state of SmB6 have been described.
