Abstract

Purpose: This study examined whether digital charting and outlining note-taking methods differ in their effects on immediate memory retention among undergraduate psychology students at Universitas Padjadjaran.Research Methodology: A within-subjects experimental design involved 108 psychology students from the 2022 and 2023 cohorts. Participants completed two note taking conditions charting and outlining presented online via Zoom for seven minutes each. Immediate memory retention was measured using separate 10 item multiple choice quizzes administered through Google Forms. Data were analyzed using the Kruskal Wallis test due to non normal distribution.Results: No significant difference was found between charting and outlining note taking methods in immediate memory retention (p > .05). Both conditions produced high levels of accuracy, with mean scores of 84.8% for charting and 80.6% for outlining. Variations in performance were observed across individual items, suggesting differences in item difficulty rather than note taking format effects.Conclusions: Digital charting and outlining methods showed equivalent effectiveness in supporting short term memory retention when learning duration and content exposure were controlled.Limitations: Findings were limited by online implementation, non equivalent learning materials, the absence of a control group, and uncontrolled individual factors such as attention and motivation.Contributions: This study provides evidence on digital note taking practices in Indonesian higher education and offers guidance for students selecting note-taking strategies in online learning environments.

Abstract

Purpose: University students are highly vulnerable to psychological distress. Self-affirmation, defined as reflecting on core personal values to maintain self-integrity under threat, may serve as a protective mechanism. This study examines the effect of listening to the Indonesian song “Diri” by Tulus on self-affirmation among psychology students at Universitas Padjadjaran (UNPAD). Methodology: A true experimental pretest posttest design was used with 78 psychology students (cohorts 2022–2023) selected via stratified random sampling using UNPAD SAS. Selfaffirmation was measured using the SSAM. The song was delivered via Spotify through Zoom. Normality was tested using Kolmogorov–Smirnov; due to non-normal data, the Wilcoxon Signed Rank Test was applied in SPSS 22. Effect size was calculated using r = |Z|/?N.Results: Mean SSAM scores increased from 5.14 (SD = 0.73) to 5.54 (SD = 0.75), a 7.8% improvement. The Wilcoxon test showed a significant difference (Z = ?6.355, p < .001) with a large effect size (r = 0.719).Conclusion: Listening to “Diri” significantly enhances selfaffirmation, indicating that music with affirming lyrical content may function as an accessible psychological intervention. Limitations: The study lacks a control group, uses a single university sample, and has limited ecological validity due to online administration.Contribution: This is the first experimental evidence that an Indonesian popular song can function as a self-affirmation stimulus, contributing to music psychology and low cost mental health interventions in higher education.
