The Cognitive Impact of Caffeine: A Stroop Test Study on Regular and Occasional Consumers

This study aimed to examine the impact of caffeine intake on selective attention using the Stroop test among individuals categorized as regular or occasional caffeine consumers. A total of 50 participants, including males and females, were conveniently sampled and divided into two groups based on their Caffeine Addiction Test scores. Individuals completed the Stroop test both before and after consuming caffeine, with a gap of 15 days between the two tests. Data analysis involved paired t-tests conducted in MS Excel. The results indicated a significant impact of caffeine consumption on selective attention, as demonstrated by notable differences in Stroop test performance. Specifically, occasional caffeine consumers exhibited a significant improvement in their test performance after caffeine intake, while no significant difference was observed for regular caffeine consumers. Moreover, a significant distinction was found in the overall Stroop test scores between occasional and regular caffeine consumers. These findings suggest that the effects of caffeine habits on selective attention may vary. Consequently, it’s essential to take into account people’s caffeine consumption patterns while investigating the impact of caffeine on cognitive strategies together with selective attention. In addition, research is needed to explore the underlying mechanisms and long-term results of caffeine intake on cognitive function. Knowing those factors will make contributions to a complete knowledge of the relationship between caffeine and cognitive overall performance.
