Predictability of a Human Partner in a Pursuit Tracking Task without Haptic Feedback

We are interested in whether humans create a model of their partner when they jointly manipulate an object in a virtual task without haptic feedback. In such a scenario the partner is perceived as a disturbance because she/he is responsible for inconsistencies between the visual and proprioceptive feedback of the individual. To gain basic knowledge on the predictability of such disturbances we compare a pre-recorded human partner with predictable (time delay) and unpredictable (random) disturbances and two additional control conditions in a pursuit tracking task. Results indicate that the influence of the pre-recorded partner is partly predictable, therefore we assume that a model of the partner's behavior is built by the human.
