A system identifies the location of a user and presents location aware stimulus material to the user. Discounts, promotions, and advertising can be delivered to the user on a wireless device based on location and path information. Stimulus material on in store monitors, billboards, and displays are modified based on information about individuals near the monitors and displays. In particular embodiments, neuro-response data is collected using a portable electroencephalography (EEG) headset while a user is exposed to stimulus materials to allow the effectiveness of the stimulus material to be determined. Stimulus materials presented can also be evaluated for neuro-response effectiveness prior to presentation to users in a location aware and personalized manner.
