Abstract
The aim of the study is to examine the effect of cerebral lateralization on visual and auditory simple reaction time and reaction asymmetry in young adults. For this purpose, 52 individuals were divided into 3 groups according to hand preference and their audio-visual reaction times were measured and compared in both hands. The obtained data were analyzed in SPSS 22.0 program. After testing for normality and homogeneity, one-way analysis of variance and LSD correction were performed for multiple groups. According to the data obtained, it was determined that hand preference had no effect on reaction time and reaction asymmetry (p>0.05). As a result, it can be said that lateralization has no effect on reaction time and reaction asymmetry.

Highlights
The aim of the study is to examine the effect of cerebral lateralization on visual and auditory simple reaction time and reaction asymmetry in young adults
We evaluated the results according to the Geschwind score (GS)
As a result of these data obtained, it was not determined that there was a significant difference between hand preference, reaction times and reaction asymmetries
Summary
Ali Paşa Kisak, Mustafa Özdal, Mehmet Vural EFFECT OF CEREBRAL LATERALIZATION ON VISUAL AND AUDITORY SIMPLE REACTION TIME AND REACTION ASYMMETRIES narrow and widen his attention. Brain asymmetry or cerebral asymmetry refers to the anatomical, physiological or behavioral differences between the two brain hemispheres. The larger, more active, or superior in performance is hemisphere dominant. The asymmetry of brain function and its evolutionary origins is an important topic of modern neuroscience. The brain is considered asymmetrical if one hemisphere is structurally different from the other and/or performs different functions. Language and speech in humans is a function controlled by the left hemisphere in the vast majority of individuals. The right hemisphere, on the contrary, appears to be involved in various emotional and spatial functions (2)
