  N A conditional is computed in the same way, except that the expected agreements are calculated only for a particular row or column on which the statistic is conditional. Hypothesis tests have been developed for Bishop et al. Specific Procedures for Calculating Different Types of Tests Plate Tests The appropriate procedure is to compare coefficients for reliability and validity. Evaluation of reliability should compare test and retest data; evaluation of validity should compare plate test data and anomaloscope data. In many cases, plate tests have been compared with other plate tests of known high validity. This procedure is less desirable than comparison with a standard anomaloscope. For the FM hue test, calculation of coefficients is possible only for comparisons of classification data.

  Other standard statistical procedures, including analyses of variance, may be used to compare error scores. Anomaloscopes If appropriate technique is used, reliability of anomaloscope data should be high. If necessary, reliability of match midpoint or matching range can be evaluated by means of a scatter plot. Instrument values for the anomaloscope on initial testing are plotted against values obtained on retest. Since match midpoints are usually distributed normally and symmetrically Lakowski, , a correlation coefficient can be computed. In order to evaluate the validity of new anomaloscopes, the diagnostic categories obtained from the new anomaloscope i. It is appropriate to use scatter-plot and correlational analyses to compare match midpoints and matching ranges of two anomaloscopes that have identical mixture primaries and test wavelengths.

  With the wrong illuminant, deutans may also make fewer errors in an arrangement test, such as the FM hue test or the Farnsworth Panel D In addition, protans may show rotation of the error axis. Extreme protanomalous trichromats and protanopes may even show a deutan pirofile Higgins et al. Thus, unfiltered tungsten lamps cannot be used as illuminants for these tests, since those lamps will not give correct results. Ordinary window light is too variable in both illuminance level and spectral composition to be an adequate source for color vision testing. The use of fluorescent tubes in color testing has been investigated, with variable results Rowland, ; Katavisto, Ordinary commercially available fluorescent tubes are not generally appropriate for testing color vision. In recent years, high-quality fluorescent lamps have been developed especially for use in color comparison work.

  Table lists, describes, and names the supplier of some illuminants that are commercially available in the United States. The table includes three illuminants that use a tungsten source with filters, five fluorescent sources, and one xenon source. For some of the illuminants, correlated color temperature, color-rendering index, and approximate level of illumination are shown.

  The correlated color temperature specifies the spectral energy distribution of the source; Standard Illuminant C has a correlated color temperature of The color-rendering index expresses how closely a test source can reproduce color in comparison with a standard source. An index of is perfect rendition Wyszecki and Stiles, The Macbeth Easel Lamp, designed for use with screening-plate tests, is a widely used illuminant in the United States. The lamp is mounted in a stand which allows source, plate test, and observer to be in correct spatial relationship. The daylight filters for the lamp vary slightly but are close to Standard Illuminant C. The Macbeth Daylight Executive consists of a metal light box that provides diffuse illumination. The various color tests placed in the box are viewed in correct spatial relationship to the observer. The color test glasses Pokorny et al. The color-rendering indices for the fluorescent lamps listed in Table are almost as good as those for the filtered tungsten sources or for the one filtered xenon source.

  The test material should be approximately perpendicular to the observer's line of regard to avoid glare or gloss. The illuminant should be mounted above the test material and adjusted to provide even and direct illumination. The distance of the illuminant from the material determines the level of illuminance and the area of illumination. Plate tests should be presented at a distance of about 75 cm. Arrangement tests are presented at a distance comfortable for manipulation about 50 cm. Available in United States from Alfred P. General Description. The Nagel Model I anomaloscope was designed to measure the Rayleigh equation in the general population using spectral lights.

  The instrument is designed to present a circular split field. In the lower half, a spectral yellow nm appears. The luminance of the yellow half can be continuously varied by turning a knob. When this knob is adjusted, the yellow half of the field varies from dark at scale zero to increasingly brighter yellow as the scale increases. The upper half of the field is filled with a mixture of spectral yellow-green nm and spectral red nm. The relative proportions of green and red, from all green through any mixture to all red, can be continuously adjusted by a knob. At scale zero, the upper field appears yellow-green only spectral yellow-green present.

  As the knob is adjusted to higher numbers thereby increasing the proportion of red to green primary in the mixture , the upper field changes in appearance from yellow-green, to green-yellow, yellow, orange, and finally yellow-red at knob value 73 only spectral red present. A normal observer can achieve a good color match between the two halves of the field by adjusting the red-green knob and the yellow luminance knob. The calibration is set at the factory; the normal match usually occurs between 40 to 50 units of red-green mixture and about 15 units of yellow. The red and green primary lights have approximately equal luminance. The observer views the split field through a telescope tube. A focusing barrel on the telescope allows for minor adjustments, which are accompanied by a 10 percent variation in the field size. The field size in the currently available Nagel ranges from 1. On the front panel below the telescope tube is a Trendelenburg adapting field for presentation of a uniform adapting field Illuminant A.

  The test should be run in darkness or semidarkness. Measurement requires a skilled and trained person. Instructions written by Linksz accompany the instrument, but no scoring sheets are available. In the Linksz procedure, the examination starts with a three-minute preadaptation to the lighted Trendelenburg screen on the front panel of the Nagel Model I. The adaptation light is extinguished, and the observer is presented with a normal match prepared by the examiner in advance. If asked to comment on the color appearance, the normal observer and the dichromat will say that the colors look the same or appear as shades of the same color.

  The anomalous trichromat will usually say that the mixture field appears red deuteranomalous trichromat or green protanomalous trichromat. At this point, some examiners allow the observer to use both red-green and yellow controls to adjust the two fields to equality. If the normal match, or one close to it, is accepted the next step is to evaluate the range of acceptable red-green ratio values. For a normal observer this range will be small between 0 and 5 scale units. The examiner turns the red-green mixture 5 scale units from the initial match.
