	abstract = {The  present  experiment  examined  the  influence  of  final  target  position  on  grasp  posture  planning during a three-segment object manipulation task in which 
the  required  object  orientation  at  the  first  target  position was unconstrained. Participants grasped a cylindrical object from a home position, placed it at an intermediate position  in  a  freely  chosen  orientation,  and  subsequently placed it at one of four final target positions. Considerable inter-individual  differences  in  initial  grasp  selection  were observed which also led to differences in final grasp postures.  Whereas  some  participants  strongly  adjusted  their initial grasp postures to the final target orientation, and thus showed  a  preference  for  end-state  comfort,  other  participants showed virtually no adjustment in initial grasp postures,  hence  satisfying  initial-state  comfort.  Interestingly, as  intermediate  grasp  postures  were  similar  regardless  of initial  grasp  adjustment,  intermediate-state  comfort  was prioritized by all participants. These results provide further evidence  for  the  interaction  of  multiple  action  selection constraints in grasp posture planning during multi-segment object manipulation tasks. Whereas some constraints may take strict precedence in a given task, other constraints may be  more  flexible  and  weighted  differently  among  participants. This differentiated weighting leads to task- and subject-specific constraint hierarchies and is reflected in inter-individual differences in grasp selection.},
