title: Comparison of voice stress reactivity under psychological stress test and simulated Mir docking manoeuvre.
abstract: The relation between the results of laboratory tests and results of the interesting professional work is a very difficult one.  The same is true for the relation between training and real performance.  The pilot controlled MIR-docking manoeuvre is in reality a very seldom but very important one.  The training of this manoeuvre is a very special professional work and only for cosmonauts available.  But the objective estimation of the performance and the used objective and subjective needs is nevertheless necessary.  Even for the subjective "stress"-feelings during task solving it is often impossible to get reliable data without any physiological measurements.  The use of electrodes, cables and equipments is hardly limited during real work.  Sometimes only the voice is available over more or less quality communication channels.  So it is the case during the training and the real pilot controlled MIR-docking manoeuvre.  Based on findings in the literature and own experiments analyzing the relation between fundamental voice frequency (F0) and subjective stress feelings we tested the hypothesis that a on-line measurement of F0 can be used for stress evaluation during standardised training sessions of MIR-docking manoeuvres.
