Experiment on the Application of Polychromatic, Monochromatic, and Achromatic Educational Materials and Their Effect on Memory Recall

Abstract

This study investigates the impact of polychromatic, monochromatic, and achromatic-based educational materials on memory recall. Specifically, it aims to evaluate which method notably influences retention.  The research, conducted with 45 college students, utilized true experiment research design measured in a between-subject approach, where participants were equally and randomly distributed to three groups: polychromatic, monochromatic, and achromatic. A structured memory recall test was administered after participants engaged with the study materials under their assigned conditions. Descriptive Statistics revealed that using polychromatic educational materials yields the highest average score in memory recall (M = 10.3, SD = 2.09). The analysis of variance (ANOVA) revealed a statistically significant difference between the conditions (F=4.08, p=0.024). However, the post-hoc comparison test showed that only the use of polychromatic educational materials in contrast with the use of achromatic yielded a statistically significant difference (p = 0.020, d = 1.030) compared to the use of monochromatic against achromatic-based educational materials (p = 0.179, d = 0.660) and the use of polychromatic opposed to the use of monochromatic educational materials (p = 0.573, d = 0.370). Findings emphasized the significant role of color in facilitating memory recall, which is supported by existing literature. Limitations of the study include the colors of the materials used to highlight the information in the given passage, the setting where the experiment was conducted, and the number of participants involved. Moreover, the study contributes to the limited literature in the context of color psychology and provides insights for developing effective learning strategies.
