We use tools and handle objects every day. Thereby, the selection of a specific grasp sets the stage for subsequent tool use actions or object manipulations: Whereas clever grasp planning can facilitate a subsequent object manipulation, an inappropriate grasp selection may hinder it or even render it impossible. However, how grasps for object manipulation are planned is an open question and different explanation have been proposed. In my presentation I will focus on the (apparent) dichotomy of goal-directed and habitual processing and present experiments that shed light on the contribution of both modes of processing. These experiments show that grasp planning – including the adjustment of the grasp to an upcoming object manipulation –is predominantly a habitual process.
