While technological advances might have simplified many aspects of everyday life and work contexts alike, more often than not they have also introduced new challenges and levels in complexity when performing a related task. One simple example for such a situation is the use of a computer mouse: motion in the horizontal plane is translated to vertical motion on a computer monitor with different settings of cursor speed or even acceleration. Situations become even more complex when looking at work contexts such as laparoscopic surgery or crane operators, for example.
As a result, it has often become necessary to learn and possibly even generalize a transformation between the motor action and the resulting visual effect of this action. Such generalizations of sensorimotor learning are often conceptualized by means of updating internal models to counteract distorted visuomotor properties. While these theories acknowledge the influence of context, recent results point to a particular influence of the specific perceptual and spatial properties of the visual workspace.
Against this background, the current project is aimed at exploring the exact underlying parameters and mechanisms by using a sliding paradigm that primarily probes the original motor programming in tasks that involve a visuomotor rotation.
