The effect of cerebral lateralization on psychomotor performance in sedentary youth

The aim of this study to investigate the effect of cerebral lateralization on psychomotor performance in sedentary youth. Our study was designed according to ex post facto experimental design. The manipulative effect of laterization on psychomotoric traits as an unmanipulated independent variable has been investigated. The study involved 60 sedentary male subjects in the 15-18 age group. Laterization test and psychomotoric performance tests were applied to the subjects within the scope of this study. The obtained data were analyzed in SPSS 22.0 program. After the normality and homogeneity test, Kruskal Wallis test was applied to analyze the difference between multiple groups (the flatness and distortions of the data that do not show normal distribution were evaluated and those in the range of +/- 2.00 points were assumed to show normal distribution). Values were presented as mean and standard deviation and examined at a significance level of 0.05. According to the results obtained, it is said that while it creates a significant difference in some tests, it does not have a significant effect in some tests. Therefore, the hand preference of sedentary individuals to be determined on psychomotoric performance tests by participants who used dominant right hand, dominant left hand and both hands no significant differences were seen between participants who used the dominant right hand, dominant left hand, and both hands. However, in the evaluation of reaction and attention test data, it can be said that dominant right-handers perform better than dominant left-handed individuals. At the same time, according to the comparisons between both hand users and dominant left hand users, it can be said that there is a significant difference in favor of both hand users.
