The effect of exercises using the Cogni plus device on developing perception of handball referees

Abstract

The study aims to use modern technology in developing handball rulers using exercises of the Cogni Plus device and to identify the effect of exercises in developing perception of the handball rulers. The study hypothesizes that the exercises of the Cogni Plus device have a positive effect on developing perception of handball referees. The researchers used the experimental method in the one group method to suit the nature of the problem studied. The study community identified the handball referees accredited in the Central Iraqi Handball Federation for the sports season 2016-2017 and they numbered (43) first-class rule workers, and handball referees were chosen in the Middle Euphrates region In Iraq, in the simple random method, where the number of the sample became (10) rulers, the arithmetic circles of the perceptual variables ranged, so the arithmetic mean for the total field of vision (169.1±1.203), visual focus (49.184±1.14), divided attention (79.381±1.242), and emotional maturity (1.824±0.081) and response time Verb (0.682±0.021), after prolongation The direct awareness of the Vienna system and its devices, the researchers chose the perimeter perception test and the Alertness - phasic s1 program was selected. Through the use of the test, the researchers were able to identify the exact shape of the device, how to conduct the test, and the reliability of the results obtained. The pre-test was carried out and the curriculum was implemented The training that took (8 weeks) and after completion, the post-test was conducted. The results of the study were presented and discussed. The most important conclusions were that the exercises of the Cogni Plus had a positive effect on the development of perceptual variables, namely (total field of view - divided attention - visual focus - visual reaction - emotional maturity) among handball referees.
