Design a dynamic visual & audio reaction time software test and assessment of its validity and reliability in the hearing handicapped

Ghamar Mehri


Reaction time is necessary for successful performance in most sports activities.  It’s often performed using simple visual and auditory, but in this new study, to determine visual methods used Dynamic reaction time software. This study aimed to investigate and compare the dynamic and simple visual reaction time in normal and deaf subjects, for this purpose, 18 normal students of Jabir Ibn Hayyan and 15 deaf students of Omid and Tavana schools were selected as subjects.  Characteristics of subjects and Information of test and then compare the results of each individual was recorded after the pre-test and post-test on each individual separately by computer software. Results of intra-class correlation coefficient (alpha Cronbach) show that’s  normal groups in  simple visual test was higher than deaf Groups,  But the results of dynamics visual test in normal and deaf groups not acceptable validity. There was very little correlation between the mean reaction time in a simple and visually dynamic Test of the first stage (r=0/208), But In the second stage, observed a very good correlation (r=0/839). Also Simple visual comparison in normal and deaf Groups did not show significant differences between pre-test and post-test. However, visual and dynamics Test in the normal and deaf groups showed a significant difference in pre-test and post-test. Independent t-test showed that not significant differences between the simple visual and dynamic visual test between the two groups. We recommend a simple visual and dynamic testing in athletes and non-athletes with physical disabilities will also be discussed.
