Rate of information processing and reaction time of aircraft pilots and non-pilots

摘要

Reaction time and rate of information processing are cited as critical components in the make-up of pilots. A need was identified to establish the validity of various chronometric measures in the selection of pilots. Fifty-eight military and commercial pilots and twenty non-pilots were subjected to Schepers' Computerised Information Processing Test Battery, which measures reaction time, form discrimination time, colour discrimination time, rate of information processing (perceptual) and rate of information processing (conceptual). Five hypotheses and one postulate were formulated and tested. The results indicate that pilots could be differentiated from non-pilots with 92,3% accuracy. However, the results need to be cross-validated before they are used for selection. Opsomming Reaksietyd en tempo van inligtingverwerking word as kritieke komponente in die samestelling van vlie?niers beskou. ‘n Behoefte is ge?dentifiseer om die geldigheid van verskeie chronometriese metinge in vlie?nierskeuring te bepaal. Agt en vyftig militêre en kommersi?le vlie?niers en twintig nie-vlie?niers is onderwerp aan Schepers se Gerekenariseerde Inligtingverwerkingstoets-battery wat reaksietyd, vormdiskriminasietyd, kleurdiskriminasietyd, tempo van inligtingverwerking (perseptueel) en tempo van inligtingverwerking (konseptueel) meet. Vyf hipoteses en een postulaat is gestel en getoets. Die resultate dui daarop dat vlie?niers met 92,3% akkuraatheid van nievlie?niers onderskei kan word. Die resultate behoort egter eers gekruisvalideer te word voordat dit finaal vir keuring gebruik kan word.
