Brief Summary
This study aims to evaluate the effects of caffeine dependence on hand reaction time and fine motor skills in university students. By comparing individuals with high and low daily caffeine intake, the research will assess whether excessive caffeine consumption is associated with impaired upper extremity performance. Reaction speed will be measured using the Nelson Hand Reaction Time Test, and manual dexterity will be assessed with the Purdue Pegboard Test.
