摘要

This study continues a series of psychophysical experiments investigating the characteristics of visual recognition of target stimuli of different colors and sizes in early preschool children. A previously developed game-based method was used to make measurements using a touchscreen monitor to present images of geometric shapes in silence and in the presence of noise (acoustic background corresponding to “children’s polyphony”). Noise was delivered through headphones at an intensity of 45 dB (the loudness level of conversational speech). Experimental participants were children with normal vision and hearing, aged 3–4 years (n = 60) attending a city kindergarten. The data obtained on the expanded sample confirmed previously identified patterns: children of this age performed significantly worse in making selections based on the “color” feature than on the “size” feature (p < 0.01); the introduction of background noise corresponding to “children’s polyphony” increased visual target search time, especially in tasks of selecting a “color” target. Comparative analysis of the results obtained in subgroups of children displaying different levels of activity and anxiety revealed significant differences, which were consistent with the preliminary data from the previous study. The results of the present study have practical implications for organizing preschool education, taking account of the specific psychophysiological profiles of children and their anxiety levels, as well as special education for children with developmental delays.
