Figure 5. Aiming error as function of instantaneous visuo-kinesthetic rotational misalignment.

Scatter diagram, for the whole population of subjects, of the aiming error 300 ms after movement onset as a function of the rotational misalignment between the visual disturbance (θvis) and the kinaesthetic disturbance (θkin). The misalignment is null by definition in the F and VK+ conditions; it is randomly distributed across the whole range of possible values in all the other conditions. The slopes of the regression lines have the following values, for the K, V, VK− and VKP conditions, respectively: 0.749, 0.799, 0,697, 0.679; these values all differ significantly from 1.
