Abstract
This quasi-experimental design of the study aimed at determining the effects of caffeine consump-
tion 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 differ-
ence 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 improve-
ment 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.
