The Impact of Musical Genre on Cognitive Memory Retention in Adults

Thesis Abstract

This study investigates the influence of musical genre on cognitive memory retention among adults, addressing a growing interest in the potential cognitive benefits of diverse musical stimuli. The research aims to systematically examine whether listening to different musical genres—specifically classical, jazz, pop, and electronic—differentially affects short-term and long-term memory performance in adult individuals. The specific objectives include (1) assessing the effects of each genre on immediate memory recall, (2) evaluating the impact on delayed memory retention, (3) exploring participants’ subjective perceptions of each genre’s influence on cognitive performance, and (4) identifying potential moderating factors such as age, gender, and musical background. Employing a quantitative research design, the study adopts an experimental within-subjects framework, enabling the comparison of cognitive performance under different musical conditions within the same participants. The population comprises 120 adults aged 25 to 45 years, recruited through stratified random sampling from a university community to ensure demographic diversity. Participants are screened for hearing impairments, neurological conditions, and musical training, with a balanced distribution across gender and musical experience levels. Data collection involves a combination of standardized cognitive memory assessments and self-report questionnaires. The primary instruments include the Digit Span Task and the Rey Auditory Verbal Learning Test to measure immediate and delayed memory, respectively. Musical stimuli are curated to ensure consistency in tempo, volume, and familiarity, with participants exposed to each genre in a randomized order during testing sessions. To validate the musical stimuli and control for confounding variables, subjective ratings of emotional arousal and mood are obtained immediately after exposure. Data analysis employs repeated-measures ANOVA to compare memory performance across different musical genres, with post hoc tests to identify specific differences. Hierarchical multiple regression analyses are conducted to assess moderating effects of demographic factors. The theoretical framework integrates Cognitive Load Theory to explain how different musical stimuli may influence cognitive processing and memory encoding, complemented by the Arousal Theory to consider the emotional impact of each genre on cognitive engagement. The anticipated results suggest that classical and jazz music, characterized by complex harmonic structures and moderate tempo, will facilitate higher memory retention scores compared to pop and electronic genres, which tend to have simpler, repetitive rhythmic patterns. It is further expected that individual differences in mood and emotional arousal will moderate these effects, with more positive emotional responses correlating with better memory performance. The findings are poised to contribute novel empirical evidence to the field of neurocognitive music therapy and cognitive enhancement, extending knowledge about genre-specific effects on memory processes. This research aims to inform practitioners in educational and therapeutic settings on optimal musical stimuli for cognitive facilitation. The main conclusion will emphasize the differential impacts of musical genres on memory retention, advocating for targeted musical interventions tailored to individual cognitive and emotional profiles. Recommendations include developing genre-specific auditory cognitive training programs and exploring longitudinal effects in clinical populations. The study also proposes future research directions to investigate underlying neural mechanisms through neuroimaging techniques, thereby enriching the understanding of music-cognition interrelations in adult populations.
