[Study of mental performance of MIR cosmonauts]

Prediction of mental performance is one of the major goals of space psychophysiology. This paper discusses experimental data about mental performance of the cosmonauts A. Alexandrov, A. Momanda, V. Savinykh and V. Polyakov as predicted by means of a Soviet-Bulgarian psychodiagnostic unit Pleven-87. The investigations were performed within the framework of the Prognosis experiment on Mir. The experimental results demonstrated that the psychodiagnostic unit Pleven-87 provided reliable predictions, using adequate and sensitive methods. This unit can find application in mental performance evaluation and prediction.
