Neuromarketing employs cognitive-behavioral science and technologies like fMRI, EEG, eye tracking and biometrics to study consumer brain responses and behavior in response to marketing stimuli. Learning and memory affect buying behavior, with learning being the acquisition of new knowledge and skills, and memory being the expression of what was learned. Intertemporal choice in marketing examines how consumers weigh smaller, sooner rewards versus larger, later rewards and tend to prefer the former.
