The present invention relates to a method for diagnosing visuospatial disorientation or assessing visuospatial orientation capacity in a subject including conducting an optic flow test on the subject, recording results of the test, and comparing the results of the test against a threshold for optic flow perception. The present invention also relates to a method for diagnosing visuospatial disorientation or assessing visuospatial orientation capacity in a subject including conducting an optic flow test on the subject, conducting at least one optic perception and interpretation test other than an optic flow test on the subject, recording results of the optic flow test and the at least one optic perception and interpretation test, making a first comparison of the results of the optic flow test against a threshold for optic flow perception, and making a second comparison of the results of the at least one optic perception and interpretation test against a threshold for the at least one optic perception and interpretation test. Another aspect of the present invention is a method for diagnosing visuospatial disorientation or assessing visuospatial orientation capacity in a subject including conducting an optic flow test on the subject, measuring brain wave responses to record an evoked potential in response to the optic flow test, and comparing the evoked potential against a threshold for optic flow perception. The present invention is also related to a method for enhancing visuospatial orientation capacity in a subject which includes presenting optic flow stimuli on a device to provide a sense of self-movement.
