Computerized color-vision test based upon postreceptoral channel sensitivities.
An automated, computerized color-vision test was designed to diagnose congenital red-green color-vision defects. The observer viewed a yellow appearing CRT screen. The principle was to measure increment thresholds for three different chromaticities, the background yellow, a red, and a green chromaticity. Spatial and temporal parameters were chosen to favor parvocellular pathway mediation of thr...
متن کاملEvaluation of the Waggoner Computerized Color Vision Test.
PURPOSE Clinical color vision evaluation has been based primarily on the same set of tests for the past several decades. Recently, computer-based color vision tests have been devised, and these have several advantages but are still not widely used. In this study, we evaluated the Waggoner Computerized Color Vision Test (CCVT), which was developed for widespread use with common computer systems....
متن کاملMultiple Color Matches to Estimate Human Color Vision Sensitivities
A color matching experiment was designed and carried out to estimate human observers’ color matching functions (CMFs). 61 colornormal observers participated in the experiment. Their results were traced back to physiological factors using a mathematical vision model. The experiment time was 15 minutes, which is much faster than previous research aimed at determining color matching functions.
متن کاملClinical validation of a computerized psychophysical test for color vision and contrast sensitivity
Purpose: To determine the reliability of TwoDocs computerized test for the evaluation of color vision and contrast sensitivity in normal adults. Methods: Thirty normal volunteers aged from 20 to 30 years (mean 23.3 years) had their color vision and contrast sensitivity tested by a new computerized test (TwoDocs test). Informed consent was obtained from all participants before testing. Inclusion...
متن کاملconstruction and validation of a computerized adaptive translation test (a receptive based study)
آزمون انطباقی رایانه ای (cat) روشی نوین برای سنجش سطح علمی دانش آموزان می باشد. در حقیقت آزمون های رایانه ای با سرعت بالایی به سمت و سوی جایگزین عملی برای آزمون های کاغذی می روند (کینگزبری، هاوسر، 1993). مقاله حاضر به دنبال آزمون انطباقی رایانه ای برای ترجمه می باشد. بدین منظور دو پرسشنامه مشتمل بر 55 تست ترجمه میان 102 آزمودنی و 10 مدرس زبان انگلیسی پخش گردید. پرسشنامه اول میان 102 دانشجوی س...
