USING COMPUTER-GAMING TESTS TO EVALUATE HAND SIMPLE REACTION TIME TO VISUAL STIMULUS
Abstract
Aim. The research aimed to identify the hand reaction time to visual stimulus depending on laterality, by using the computer-gaming test. The computer technology can be applied to improve the reaction time of both dominant and non-dominant segment. Method. The research consisted of a group of 60 students from physical education and physio-kinesiotherapy specialties of UMF Tirgu Mures, aged M±SD=23.4±1.61, from which 12 subjects had left hand dominance and 48 had right hand dominance, devided in two groups: male and female (N=30). The study was carried out on October 5-15, 2015 when the students took the computer-gaming test of humanbenchmark in order to evaluate the reaction time to frontal visual stimuli. The testing was carried out with both right and left hand. Results. The computer-gaming testing for the reaction time evaluation of the right hand was X±SD=298.41±46.86, and for the left hand X±SD=278.41±42.67. The tests result analysis for both hands highlight superior results for the reaction time of the left hand, therefore: Xdifference±SD=11.08±31.75, tvalue=2.70 for p<0.05, r=0.760. Comparing the males group with the females group, the average differences for the right hand were Xdifference±SD=6.633±65.81, and for the left hand Xdifference±SD=5.533±64.80. The females’ results were statistically significant. The correlation was strong for both groups. Conclusion. The research results reveal that the left hand has a reduced simple reaction time to frontal visual stimuls as opposed to the right hand, by using the computer-gaming test. The males group registered superior values as compared to the females group, for both executions. The study results show significant statistical differences and a strong correlation between the execution time of the right and left hand, in favour of the left hand which registered superior results.
