Abstract

 The purpose of this study was to investigate the relationship between kinetic visual acuity and reaction time in college students. Eighteen male college students, mean age: 21.5±2.2 years, participated in this study. Static and kinetic visual acuity and simple and choice reaction time were measured. In addition, visual evoked potential using pattern reversal stimulus was recorded. These items were measured by the following apparatuses: KOWA AS-4F (visual functions), Takei Scientific Instruments T.K.K.1264b (reaction times), Biopac MP150, AcqKnowledge software, and Biopac ERS100 amplifier (visual evoked potential). The results indicated that there was no significant correlation between kinetic visual acuity and reaction time(KVA-SRT: r=-0.135 p=0.595, KVA-CRT: r=0.183 p=0.468, KVA/SVA×100-SRT: r=-0.060 p=0.813, KVA/SVA×100-CRT: r=0.024 p=0.925). Further, there were no significant relationships between reaction time and the latencies of visual evoked potential (SRT-N70: r=-0.323 p=0.191, SRT-P100: r=0.453 p=0.059, SRT-N140: r=0.219 p=0.383, CRT-N70: r=0.034 p=0.893, CRT-P100: r=-0.271 p=0.277, CRT-N140: r=-0.049 p=0.847). Therefore it was suggested that quick reaction time was not linked to high kinetic visual acuity. In this study, some data relative to mechanism of kinetic visual acuity were obtained.
