Electroencephalographic, Heart Rate, and Galvanic Skin Response Assessment for an Advertising Perception Study: Application to Antismoking Public Service Announcements
August 28th, 2017
The following protocol describes a series of operational and computational steps required to properly estimate the emotional and cerebral reaction of a group of subjects towards a selected number of Public Service Announcements (PSAs) against smoking, aired in the USA and Europe during the period between 1998 and 2015.
The overall goal of this electroencephalographic, heart rate, and galvanic skin response assessment is to study and measure the unconscious neurophysiological perception of advertising and, particularly, of public service announcements.This method can help us come up with key questions in the neuroscience field, such as the assessment of the cognitive and emotional reaction to advertising as well as its impact in the population subgroups.The main advantage of this technique is that it enables the measurements of neurophysiological unconscious, reactions to the stimuli, and obtains significant results, even with a number of participants lower than that required in traditional marketing researches.Describing and illustrating the procedure would be Anton Giulio Maglione and Enrica Modica, which are out two bioengineering researcher in my lab, as well as Myriam Carat

Frequently Asked Questions
Executive Industry Relevance
This protocol provides a neurophysiological framework for evaluating unconscious consumer responses to public health messaging, offering biopharma R&D teams a method to de-risk communication strategies in disease awareness campaigns. By quantifying approach-withdrawal bias, cognitive effort, and emotional arousal through EEG and autonomic signals, the approach supports predictive confidence in message resonance before large-scale deployment. This enables early-stage hypothesis testing of PSA efficacy, reducing reliance on self-reported data and improving translational continuity from concept to population impact.
Strategic Applications in Biopharma R&D
Early Discovery & Target Validation
- Scientific Value: Interrogates therapeutic hypotheses by measuring unconscious emotional and cognitive responses to health-related stimuli.
- Operational Value: Enables biological de-risking of messaging concepts through quantifiable neurophysiological indices prior to audience testing.
Screening & Assay Development
- Scientific Value: Prepares validated biological response systems for downstream workflows by standardizing EEG asymmetry, theta effort, and autonomic emotional index measurements.
- Operational Value: Addresses assay reproducibility and quantitative output consistency across stimulus conditions and participant groups.
Translational & Preclinical Research
- Scientific Value: Supports disease-relevant system modeling by linking testimonial-based PSAs to heightened emotional index values, reflecting empathy-driven engagement.
- Operational Value: Ensures continuity from discovery through preclinical validation by aligning neurophysiological readouts with behavioral intent in public health contexts.
Pipeline & Workflow Integration
The method fits within the discovery continuum, supporting early hypothesis testing in disease awareness campaign development before progressing to message refinement and population-level validation.
- Discovery Biology: Supports hypothesis testing and pathway clarification by isolating neural and autonomic responses to specific PSA elements such as fear appeals or testimonials.
- Screening: Describes assay readiness through standardized EEG and autonomic signal processing, enabling reliable comparison of campaign variants.
- Analytics: Highlights frontal alpha asymmetry (approach-withdrawal), frontal theta (cognitive effort), and combined GSR-HR emotional index as quantitative readouts for comparing stimulus conditions.
- Translational Research: Connects method to preclinical continuity by linking emotional index elevations to empathic messaging, informing risk-adjusted advancement of campaign concepts.
- Enterprise Reuse: Frames the protocol as a reusable neurophysiological screening platform for evaluating multiple public health messages across therapeutic areas.
Operational & Enterprise Impact
- Scientific Value: Predictive confidence in message efficacy, reduction of mechanistic ambiguity in emotional response pathways.
- Operational Value: Standardization, reproducibility, and scalability of neurophysiological assessment across labs and stimulus sets.
- Strategic Value: Better go/no-go decisions in campaign selection, capital efficiency in creative development, reduced late-stage messaging failure risk.
- Portfolio Impact: Risk-adjusted prioritization of PSA concepts based on neurophysiological resonance, improving allocation of public health communication resources.
Implementation Considerations
- Requires expertise in electroencephalography, autonomic physiology, and biosignal processing.
- Dependent on EEG acquisition systems, heart rate and GSR sensors, and spectral analysis software for index derivation.
- Necessitates cross-team standardization between neuroscience, marketing, and behavioral science units for consistent protocol application.
- Involves adaptation considerations when applying indices across diverse participant populations or cultural contexts.
- Limited by the need for controlled laboratory settings to minimize motion artifacts and ensure signal fidelity during stimulus presentation.
