CAFFEINE CONSUMPTION AND ITS EFFECTS TOWARDS YOUNG ADULTS’ SHORT-TERM MEMORY RECALL

Summary/Abstract: This quasi-experimental design of the study aimed at determining the effects of caffeine consumption towards young adults’ short-term memory recall. This study utilized purposive sampling method wherein a total of 40 young adults from Kiblawan, Davao del Sur were selected as the research respondents of this study. They were divided into two groups: an experimental group and a control group, with the experimental group consuming caffeine. The following statistical tools were employed: The mean was used to determine the pre-test and post-test scores of controls and experimental group. The T-test for Independent Samples was used to address the significant difference between the pre-test mean scores of controls and experimental groups. Sample T-test was employed to assess if there was a significant difference between the pre-test and post-test mean scores of young adults in experimental and control groups. And analysis of covariance (ANCOVA) was utilized to determine significant difference in the post-test mean scores between the control and experimental groups with pre-test means scores of covariates. Results revealed that before the implementation of the interventions, both levels of performance of the groups are categorized below the average level of performance in short-term memory recall, which implies that they were having difficulty to recall the words that were tasked to recall. The result showed that there is an improvement in the short-term memory recall of young adults in the experimental group after being exposed to caffeine. The post-test performance of the control group found to be at the low average level of performance, similarly, the experimental group found to be at the low average level of performance as well. Finally, the study revealed that caffeine consumption has a little amount of effect on the short-term memory recall of the participants.
