✦ Synopsis

With time as the criterion to be optimkd, the divergencesfiom optimal had movements show systematic diAfirerues of their control signal variabh with respect to single behaviours. To clnri3 these relations+, this study uses manipulation and mathematical analysti of the 6th order nonlinear head movement model, i.e. the threefild approach of sensitivity analysti'. In addition to sensitivity coe@ients, graphs and trajectories sensitivity jkctions have been analysed. This is the sensitivity of a nominal head movement to changes of the modelparameters during the time course of th movement. T&his demonstrated both th-e specific change of the visco-inertial properties of the head movement model during th movement and also th potential pathological dejkits that may occur.

A non-linear sixth order homeomorphic model, fitted with parameters based on eye movements and physiological data, was tuned so that it provided good simulations for the shapes of the magnitude, velocity and acceleration trajectories. Excellent quantitative agreement was obtained in terms of the Mai
