  5. Which movement parameters cause interference during the preparation of bimanual movements? Symmetric Starting locations AsymmetricAmplitudes AsymmetricTarget locations Symmetric Starting locations Symmetric Amplitudes Symmetric Target locations SAT All symmetric SAT

  6. All symmetric SAT Symmetric amplitudes Asymmetric starting, targets SAT

  7. Symmetric starting Asymmetric amplitudes, targets SAT All asymmetric SAT Symmetric targets Asymmetric starting, amplitudes SAT
