METHOD FOR TESTING A SPATIAL APTITUDE ANOMALY AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

The invention relates to a method for testing a spatial aptitude anomaly and to a device for carrying out said method. The inventive device comprises an arrangement (1) for fixing a human head, a first transparent screen (2) arranged in a close field of view and a second screen which is visible through the first screen and arranged in the far field of view of a tested person. Said device also comprises means (5, 6) for selectively forming images on the first and second screens and means for recording the motion trajectory of the tested person's pupil watching said images. The inventive method is based on the detection of specific faults of the pupil trajectory such as nystagmus, interception or linearisation of the trajectory, a sudden depression of eyes, etc, when the tested person watches the image displacement along a smooth trajectory on one screen, and on the detection of the irregular modifications of the pupil size and position thereof caused by the reaction to instantaneous transfer of the image from one screen to the other, while the head of the tested persons remains in a fixed position.
