A system and method for evaluating children's visual mark recognition ability and color reaction tendency

Abstract

The invention discloses an infant sighting mark identification ability and color reaction tendency evaluation system and method. According to the development feature of visual perception ability of infants ranging from 3 years old to 5 years old, a psychophysics research method is applied, and corresponding theoretical assumptions and deductive reasoning conclusions are proposed. On this basis, through multi-factor mixed experimental design, an interactive touch-control integrated machine and a global standardized psychological experiment are adopted to generate system software E-Prime 2.0 to serve as a test platform, and the sighting mark identification ability and color reaction tendency evaluation system and method suitable for being used by infants is provided to verify and analyze the theoretical background assumptions and the deductive reasoning conclusions of the theoretical background assumptions, so that the visual chart sighting marks, ideal background setting parameters and the best limiting time for vision examination of a single sighting mark which are recommended to be used for the infants ranging from 3 years old to 5 years old, the reliability and efficiency of visual chart vision measurement of the infants ranging from 3 years old to 5 years old are improved, and the abnormal vision screening effect is improved.

Description

technical field [0001] The invention belongs to the technical field of children's visual perception ability and reaction tendency, and relates to a psychophysical experiment system. Specifically, the experiment system is used to carry out multi-task visual information testing, and to evaluate visual mark recognition ability and color reaction tendency of 3-5-year-old children Psychophysical experimental methods. Background technique [0002] Visual acuity examinations are visual psychophysical examinations. Young children are in a sensitive period of strong plasticity of human visual development, especially children aged 3-5 are not only in the high-risk period of suffering from amblyopia, but also the best time for diagnosis and treatment to reverse amblyopia. By regularly organizing visual acuity testing and amblyopia screening activities for 3-5-year-old children, objectively and scientifically evaluating the actual visual status of children at this stage can effectively...

Problems solved by technology

However, the above-mentioned scholars all adopt univariate experimental design and analysis in the system and method research, not only fail to comprehensively examine the influence of various factors (such as age, stimulus itself, background color, presentation time, etc.) The influence of tendencies and the interrelationships between various factors, and the age and individual differences in children's language comprehension and expression ability are ignored, and the various links of the experiment cannot be controlled with high precision, and the standardized sample limit that the experiment itself can provide The resulting systematic measurement error makes it difficult to guarantee the accuracy and reliability of the experimental results.
