Comparative investigation on deaf-mute children's optical reaction time

  Objective   To explore the difference of optical reaction time between deaf-mute children and normal ones, and the affecting facotrs.

  Methods   93 deaf-mute children who came from Shenyang ward deaf-mute school were selected to assess the comparative analysis in optical reaction time by using the computer reaction time test system.

  Results   there was marked difference in those test results determined by menstruating simple optical reaction time and complex optical reaction time between two groups(P < 0.01).

  Conclusion   The optical reaction time of deaf-mute children was slower than that of normal ones.It was significant to measure reaction time for directing the education to deaf-mute children and developing the function of brain.
