Investigation of the Impact of Central and Environmental Visual Feedback Resulting from Organ, Keyboard and Text on Motor Control of Keyboarding Skill

The present research investigates the impact of central and environmental visual feedback resulting from keyboarding components including used organ, keyboard elements and typed text on motor control of this subtle skill. Statistical population of the research included students of Allameh Tabatabaei University who were familiar with typing skill and aged 25±3.3 years. 12 students were selected randomly as sample members. Group members were tested in 9 steps and in each step, they received one of the various states of elimination of central and environmental visual feedback resulted from keyboarding components including: used organ, keyboard elements and typed text. In the end, individuals received tests and implementation times were recorded. The number of correct words typed per minute and also the number of typing mistakes was criteria for scoring individuals. After investigation of normality of data using Shapiro and Belk test and congruency of variances with Leveneʹs test, data were analyzed using repeated measurement variance test. Considering the significance level (0.05), results revealed that elimination of environmental and central visual feedback resulted from organ, keyboard and text has a significant impact on reduction of typing speed and increasing typing mistakes. Finally, results of the research showed that vision has a decisive role in controlling typing skill.
