Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This observational study investigates the effects of caffeine dependence on hand reaction time and manual dexterity in young adults. Caffeine is a widely consumed psychoactive substance, and its excessive intake may influence motor and cognitive performance. University students aged 18 to 30 are recruited and divided into two groups based on daily caffeine consumption and diagnostic criteria from DSM-5/ICD-10: a high caffeine group (≥300 mg/day) and a low caffeine group (20-200 mg/day). Data are collected using the Caffeine Consumption Frequency Questionnaire and behavioral assessments conducted in a controlled laboratory environment. Hand reaction speed is measured with the Nelson Hand Reaction Time Test, while manual dexterity is assessed using the Purdue Pegboard Test. Sociodemographic data and caffeine consumption are gathered via online forms. The aim is to determine whether excessive caffeine intake is associated with changes in reaction time and fine motor skills. Statistical analyses include normality testing, group comparisons, and correlation analyses, with significance set at p\<0.05. This study may provide new insights into the neuromotor effects of caffeine consumption in a university population.
