In an unpublished, still ongoing follow-up study, they are investigating the influence of different delays (movement timings) of the movement as well as repeated exposure. However, the study by Forster and colleagues focused on the feet, for which control is somewhat more limited compared to the fine control of hand movements.
We aim to replicate their experiment with the upper limbs. Additionally, a repeated exposure to this immersion will be applied to investigate possible effects of training and experience with the task.
To measure the perceived timing before and after the exposure and its link to Embodiment, participants will additionally conduct a synchronization task. Temporal offsets between the visual bubble moving in this predictable manner and the hand movement will be indicative of the perceived temporal correspondence between vision and motor control. Together with measurements of Ownership and Agency, this will be informative about the link between visuomotor control in the temporal domain and avatar Embodiment.
