[Hygienic assessment of the use of readers in elementary school].

A comparative study of the reading process and the efficacy of memory acquisition when using the reader and the paper carrier was performed in 16 3rd class pupils. Process indices show a preference for reading from the reader screen if compared to a sheet of paper. In this the gradient of the gain in mistakes is more pronounced while reading from the reader screen, that indicates to the stumbling block of the task and the psychophysiological cost of process of reading from the reader. Evaluation of the results on the efficacy of the memory function showed significant difficulty of memory acquisition when working with reader.
