Eye-Tracking Is a Study of the Features of the Perceptual Activity of Preschool Children with Hearing Impairment When Interacting With Visual Educational Material in the Learning Process

Abstract

The article is devoted to the analysis of oculomotor activity observed during the perception of visual educational material in children with hearing impairment. The need to revise traditional methods and develop new approaches to the rehabilitation and education of children with hearing impairment is associated with the increasing technological capabilities of cochlear implantation. Previous research demonstrates that children with hearing impairments have visual attentional characteristics during a learning task compared to their hearing peers. It becomes relevant to identify how visual clarity can be built into the process of teaching children with hearing impairment and perceived by them as representing the material being presented. With the help of eye-tracking, it became possible to track the change in the nature of perceptual activity in children with hearing impairment with different forms of visual stimulus educational material. The question is raised about the influence of visual cues on the success of solving problems in children with hearing impairment and how they direct the attention of children with hearing impairment, reducing cognitive load, providing depth of information processing. In order to fix the restructuring of the perceptual activity of preschool children with hearing impairment under the influence of learning influence during the experiment, we monitored the dependence of the specificity of the child's eye movements on the form of visual presentation of educational material. The study sample consisted of 9 cochlear-implanted preschool children with sensorineural hearing loss from 4 to 6 years. Eye movement was recorded using a portable eye tracker in the form factor of Pupil Labs glasses. 4 series of experiments were proposed using the educational task "classification of objects". In 4 series of the experiment, the presence explicit and hidden prompts changed, the black-and-white and color solution of the most stimulating educational material changed. It has been shown that the use of different types of cue stimuli and color scheme leads to a shift in visual attention to the target area, facilitates processing, leads to more intensive processing of stimuli, and reduces the time we need to respond to information occurring in this given space.
