Utilizing moveable EEGs, researchers discovered that when teams of individuals watch the identical well being promotion movies, their mind exercise syncs up, indicating that the message has gone past being seen and heard. This method may result in ‘neural’ focus teams and simpler well being campaigns.
Take into consideration an promoting jingle you heard as a child however nonetheless keep in mind. That, proper there, is an instance of efficient advertising. Nowadays, advertising is hard. Competitors for consideration, shorter consideration spans, misinformation and mistrust, private algorithms and echo chambers make it more and more troublesome to market merchandise successfully, particularly vital messages like well being campaigns.
Researchers from the College of Konstanz in Germany led a current examine utilizing moveable electroencephalography (EEG) to measure the mind exercise of teams of individuals watching movies of well being messages about dangerous alcohol consumption. Their findings put us a step nearer to what would successfully be next-level focus teams, so-called neuromarketing that makes use of brain-based data to make advertising simpler.
“Sadly, not all well being campaigns are equally efficient, as our analysis on the effectiveness of anti-alcohol well being campaigns has proven,” stated Harald Schupp, a psychology professor on the College of Konstanz in Germany and the examine’s co-corresponding writer.
For many years, focus teams have been used as a result of they’re an efficient method of gathering qualitative information and insights from potential customers. The researchers within the current examine thought the method might be improved by complementing these self-report measures with goal, neuroscientific ones that could be outdoors of aware consciousness.
“With neural measures, we are able to monitor the processes occurring within the brains of examine members as they watch these movies – one thing we can not do with a survey,” Schupp stated. “Neural measures thus present us with instruments for analyzing dynamic stimuli – like video or audio recordings – and, when mixed with survey information, they drastically strengthen the general evaluation.”

They used inter-subject correction (ISC) evaluation, which assesses how a stimulus, akin to a video, triggers comparable mind responses throughout viewers members. So, as an alternative of accumulating neural metrics on the particular person stage, ISC identifies frequent results seen within the brains of a number of topics. The researchers had, in a previous study, proven that robust well being messages in opposition to threat alcohol use produced heightened EEG-ISC within the lab. With this examine they wished to gather neural information from a number of examine members grouped collectively in an everyday room, in order that they used a low-density moveable EEG.
EEG is a non-invasive method of recording brain-generated electrical waves through electrodes utilized on to the scalp, or a cap with electrodes in it may be worn as an alternative. The variety of sensors used to document mind exercise can fluctuate from one to tons of. An ordinary EEG makes use of 19 to 32 electrodes, a high-density EEG makes use of 64, 128, or 256, and a low-density EEG makes use of between one and 32 electrodes. On this examine, the EEG was a 24-electrode system. Knowledge from unbiased useful magnetic resonance imaging (fMRI) scans was used to hyperlink their ISC findings to explicit mind areas.
“The current examine is an effort to maneuver well being communication neuroscience from a fundamental feasibility – or ‘can it work?’ – stage to a extra sensible implementation – or ‘does it work in follow’ – stage,” stated the researchers. “To this finish, we used a sequence of robust and weak video well being messages in opposition to dangerous alcohol use. These messages beforehand elicited distinct variations in each self-reported perceived message effectiveness and synchronized mind reactions, as captured by fMRI- and EEG-ISC.”
Forty-one members, 24 females and 17 males, with a median age of 23, have been recruited for the examine. Half participated in a gaggle watching session, the place six members at a time watched video well being messages whereas sitting in a room in a semicircle. The opposite half watched the movies one particular person at a time in the identical room. Laptops obtained the wirelessly transmitted EEG sign.
For every video, members rated its perceived effectiveness, argument energy, and the quantity of threatening or stunning content material. To gauge change in alcohol-related threat perceptions and conduct, self-report information about alcohol consumption was collected previous to therapy, instantly after the video session, and at a four-week follow-up.

The examine’s findings demonstrated a number of issues of significance. First, there was a excessive diploma of correlation between ISC information collected within the earlier examine (lab setting, high-density 256-electrode EEG) and information collected by the low-density EEG within the current one. Second, the ISC information captured replicated the findings of the sooner examine, specifically, that robust well being messages have been deemed to be simpler as a result of they enhanced inter-subject correlation. Third, the analysis demonstrated that it’s possible to evaluate neural information in a gaggle setting. Lastly, even utilizing low-density moveable EEG, the areas of the mind impacted by robust messaging – generally linked to private relevance, the outward expression of emotions and emotion (have an effect on), and a focus – have been the identical as within the earlier work. One factor differed between the earlier examine and this one: on this one, there have been no vital adjustments in alcohol threat notion and conduct.
“This exhibits that an essential sign is being obtained, one which goes past mere seeing and listening to,” stated the examine’s lead and co-corresponding writer, Martin Imhof, from the College of Konstanz’s Division of Psychology. “We assume that what we’re observing right here is the viewers partaking with the message of the movies.”
Whereas the findings point out that moveable EEG may sooner or later remodel focus teams, there’s nonetheless loads of work to be carried out. Though cheaper than the lab-based, high-density items, low-density EEG remains to be comparatively costly – and complicated. As soon as the setup is made less complicated and cheaper, it may make well being campaigns – or any advertising marketing campaign, when you concentrate on it – simpler.
“That is why we have to construct on our proof-of-concept research and contemplate how we are able to make these strategies helpful for healthcare organizations or companies as they develop their campaigns, even with out our technical sources,” Schupp stated.
The examine was revealed within the journal Social Cognitive and Affective Neuroscience.
