Discriminant analysis of clinical color vision tests and color related tasks

Validity of clinical color vision tests for air traffic control.

BACKGROUND An experiment on the relationship between aeromedical color vision screening test performance and performance on color-dependent tasks of Air Traffic Control Specialists (ATCS) was replicated to expand the database supporting the job-related validity of 13 FAA-accepted screening tests. METHODS The original experiment (10) (n = 108), and the replication (n = 136) involved a total of...

New color vision tests to evaluate faulty color recognition.

PURPOSE To develop and assess new color vision tests to be used in evaluating faulty color recognition. METHODS We developed new color vision tests to evaluate faulty color recognition. The two types of color vision tests, designed to assess faulty color recognition in color vision deficiencies, are based on principles that are different from those of the conventional color vision tests. In t...

Diagnostic Tests of Color Defective Vision

Color-Vision and Color-Blindness

Special public attention was called to the subject in 1875 by an enquiry into the causes of a railway accident which had taken place in Sweden, from which it appears that colourblindness was the cause of the disaster. Our author having described colour-sensations, goes on to discuss the theories of colour-perception and colour-blindness, classifying the latter defect as total and partial. Total...

Molecular genetics of color vision and color vision defects.

Color is an extremely important component of the information that we gather with our eyes. Most of us use color so automatically that we fail to appreciate how important it is in our daily activities. It serves as a nonlinguistic code that gives us instant information about the world around us. From observing color, for example, we can find the bee sting on an infant's arm even before it begins...
