INTRODUCTION: ONE OF THE IMPORTANT FACTORS FOR THE IMPLEMENTATION OF EXPERTISE, SKILLS, ESPECIALLY IN THE OPEN, FAST AND ACCURATE PROCESSING OF INFORMATION AND INDEX REACTION TIME (RT) (1). REACTION TIME (RT), GOOD SPEED AND ACCURACY OF DECISION MAKING IS A DECISIVE FACTOR (2). PSYCHOLOGISTS HAVE PROPOSED AS THE THREE MAIN TYPES OF TESTING REACTION TIME (3) IN A SIMPLE REACTION TIME ONLY A DRIVER AND A CALL THERE. CHOICE REACTION TIME TEST, ONE MUST RESPOND TO SPECIFIC STIMULI, SUCH AS PRESSING A KEY ON THE DRIVER'S ON TIME. A SET OF STIMULI PRESENTED RANDOMLY AND THE USER MUST RESPOND TO CERTAIN STIMULI. MOTOR FUNCTION AND ABILITY TO INTERPRET THE PERCEIVED QUALITY DEPENDS ON THE ACCURACY OF THESE PERCEPTIONS IN A SERIES OF COORDINATED MOTION IS APPLIED. VKNSH DONE A LOT OF RESEARCH ABOUT THE TIME THAT EACH ONE PERCENT ERROR IN THE MEASURED RESULTS WITH THE YAFTH AND (4) AS WELL AS PORTABLE AND WIRELESS devices EARLIER THAT THE NEW DEVICE CANNOT HAVE THESE PROBLEMS.METHODOLOGY: FOR THIS STUDY, 230 (115 BOYS AND 115 GIRLS) WERE SELECTED AS EXAMPLES. EACH INDIVIDUAL TEST WITH A NEW ELECTRONIC DEVICE TO MEASURE SIMPLE REACTION TIME, CHOICE AND EYE-HAND COORDINATION TO DETERMINE THE Validity OF THE OLD SYSTEM WAS EVALUATED. TRY SUBJECTS 6 (3 TRY THE OLD WAY AND THE NEW 3 ATTEMPTS) DID RESPOND TO THE INCENTIVES OFFERED AND THE NUMBER OF TIME PER COMPONENT WAS RECORDED. THE NORMALITY OF THE DATA FROM THE TEST KS, TO DETERMINE THE Validity AND reliability OF THE PEARSON CORRELATION COEFFICIENT OF INTERNAL CONSISTENCY COEFFICIENT (ICC) WAS USED. (5) RESULTS: THE Validity OF THE SIMPLE RT AND CHOSEN BY THE TWO SHOWS. AS CAN BE OBSERVED A SIGNIFICANT RELATIONSHIP BETWEEN THE SIZE OF THE UPPER SIMPLE REACTION TIME AND CHOICE ARE RESPECTIVELY (R=0.90), (R=0.91).OLDER devices (0.389) (0.496) IS.DISCUSSION: PEARSON CORRELATION TEST (TO CHECK THE Validity OF A SIMPLE RT SYSTEM, SELECTIVE AND HAND EYE COORDINATION COMPARED TO THE OLD SYSTEM) SHOWED A SIGNIFICANT CORRELATION BETWEEN THE RESULTS RECORDED BY THE NEW DEVICE AND OLD DEVICE FOR MEASURING RT SIMPLE, SELECTIVE AND EYE-HAND COORDINATION THERE IS A (P<0.05). AS YOU CAN SEE IN TABLE 1 AND 4 CORRELATION COEFFICIENT (R) BETWEEN THE RESULTS AND THE RESEARCHER CONSTRUCTED A SIMPLE RT SYSTEM AND THE OLD SYSTEM RT TESTING SIMPLE SELECTIONS, RESPECTIVELY (R=0.90), (R=0.91) IS OBTAINED, WHICH ACCORDING TO SOURCES, THIS REPRESENTS A VERY STRONG CORRELATION WITH EACH OTHER IN TWO BY THE SIMPLE MEASURE RT, IS OPTIONAL (8, 12). ACCORDING TO THE RESULT OF THIS TEST CAN BE SIMPLE AND RT DEVICE CAN SELECTIVELY TIME WITH ACCURACY BETTER THAN THE OLD MACHINE MEASURE. HIGH reliability (90.0) ALSO SHOWED GOOD REPRODUCIBILITY RT DEVICE RESULTS IN REPEATED MEASUREMENTS OF THIS DEVICE IS THAT IT IS IMPORTANT TO TEST DIFFERENT RT.
