Embodiment 1

[0038] Select 240 children to be tested, 80 children in the small class (3-4 years old), 80 children in the middle class (4-5 years old), and 80 children in the large class (5-6 years old). Corrected-to-correct vision was normal, and color perception was normal. During the formal test, the room was kept under constant light conditions, and the children under test sat on the adjustable children's computer chair 4 at a distance of 35 cm from the display screen of the interactive touch all-in-one machine 1, with their eyes level with the screen. The whole experimental process consists of two stages, such as figure 2 shown. in,

[0039] The first stage is the visual matching task experiment, which is implemented according to the following steps:

[0040] 1) Select the experimental materials: the main tester opens the picture materials needed for the experiment before the experiment, enters the experimental preparation state, repeatedly and patiently explains the requirements o...

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...
