Neuromarketing offers an interdisciplinary perspective for examining consumer responses to marketing stimuli through insights from marketing, psychology, and consumer neuroscience. This study investigates the relationship between consumer-perceived neuromarketing-related marketing stimuli and buying behaviour among young and middle-aged consumers in Vijayawada, Andhra Pradesh. A quantitative, descriptive, cross-sectional design was employed using data from 300 consumers, comprising 150 young adults aged 18–35 years and 150 middle-aged adults aged 36–55 years. Data were collected through a structured questionnaire containing 25 five-point Likert-scale items measuring Attention and Visual Appeal (AVA), Emotional Appeal (EA), Sensory and Packaging Appeal (SPA), Social Influence and Technology-Enabled Marketing (STI), and Consumer Buying Behaviour (CBB). Descriptive statistics, reliability and factor adequacy tests, Pearson correlation, multiple linear regression, and independent-samples t-tests were applied. All four explanatory dimensions were positively and significantly associated with CBB. The regression model was significant, F(4, 295) = 86.742, p <.001, explaining 54.1% of the variance in CBB (R² =.541). AVA showed the strongest association (β =.352, p <.001), followed by EA (β =.276), STI (β =.229), and SPA (β =.183). Significant age-group differences were observed for AVA, SPA, STI, and CBB, but not EA. The findings provide context-specific evidence that perceived visual, emotional, sensory, social, and technology-enabled marketing stimuli are associated with consumer buying behaviour. The cross-sectional, self-reported design, however, does not establish causality or direct neurological effects.
