Anyone who spends money on advertising and marketing wants to see clear results: increased sales or a stronger impact of their brand. Preferably both. But when do consumers buy? And why do they go for certain brands and spurn others? In the search for the buy button in the buyer's mind, brain research provides important insights. The Munich-based media agency Mediaplus uses these findings in its new "Neuro Impact" division. "We investigate how and why communication measures work," says Barbara Evans (37), Head of Neuro Impact. "For example, we can find out whether a campaign is better placed on TV, radio, in print or online, how long an advertisement works best and how strongly sponsorship elements are or are not received by different target groups." Evans and her team of four researchers rely on the Steady State Topography (SST, see box) research method for the development of communication measures and brands and for media planning. In this method, which was developed by Australian brain researcher Richard Silberstein, the test subjects wear a cap with electrodes and special glasses while they are shown a TV commercial, for example. "The electrodes record to the millisecond what happens in which region of the brain during the reception of the commercial," explains Barbara Evans.
The irritated areas of the brain light up deep red on the screen: If it lights up at the back, the viewer perceives the visual stimuli in the TV commercial particularly strongly. If it lights up a little further forward, laterally, the viewer's emotions are in turmoil. And if the prefrontal cortex directly behind the forehead is colored with activity, the viewer perceives something as highly relevant to them personally - a very good prerequisite for storing the images or messages shown in their long-term memory and remembering them later.
Advertising with intuitionAnd why doesn't Barbara Evans simply ask her test subjects what they particularly like or dislike about the commercial, whether they feel more rationally or emotionally addressed and whether they intend to buy the products shown? Quite simply: because they don't know. Because a large part of stimulus processing in the human brain takes place unconsciously. The brain is able to send impressions directly from the eyes into long-term memory without them ever reaching conscious perception. This also explains why thoughts or memories sometimes pop up in our head that we can't tell where they actually come from. In addition, decisions and judgments made by our intellect are often the exact opposite of intuitive decisions. Suppose a smoker sees a TV advertisement against smoking: In the first few seconds, someone lights up a cigarette, followed by an evil-evil text. At the sight of the burning cigarette, the average smoker immediately receives the message from their mirror neurons: "Smoke! You too!" It blocks all other reactions. The warning about the consequences of cigarette consumption no longer reaches the smoker, even if they have wanted to stop smoking for a long time. If you want to learn about the deeper mechanisms of action in the brain and use them for yourself, you have to leave the conscious mind out of it. This is possible with SST.
Marmalade in the testRichard Silberstein wanted to test the effect of a jam commercial. To do this, he asked 200 women to choose one brand from each of various food segments and put them in a bag. In addition to other products, there were also various jams to choose from. The test subjects were then asked to hand over the bags of food and, equipped with an electrode cap and special glasses, watch a number of commercials - including the jam commercial to be tested. The bags with the selected products would then be returned to them. After the commercial screening, however, Silberstein tricked the ladies into believing that he had mixed up the bags and asked them to select the products again. Silberstein had already observed what he now saw confirmed in the recordings of the brain reactions during the broadcast of the commercials: the women who had reacted to the brand message in the jam commercial to be tested with strong brain activity chose different products in the second round of jam selection. "The branding and the core message must be placed correctly along the storytelling," Barbara Evans explains the result. "This leads to a consumer remaining loyal to a brand or switching, depending on the goal the company wants to achieve."
Using similar tests, Silberstein also found that the effect of a brand logo fizzles out if it is placed in a commercial after conceptual closure. Conceptual closure is the moment when the brain registers the conclusion of a message or action, signaled for example by applause or two people shaking hands. Our brain then stores what we have perceived so far and cannot take in anything new for a few fractions of a second. This is a bad thing if the key visual or slogan of the advertising company is displayed at this very moment. However, this is exactly what is standard today. Do a short self-test: How many funny commercials can you remember - without knowing which product they were advertising and which companies were behind them?
Even with sponsorship, it makes a difference whether the sponsor's logo is placed on the ground, on the board or on a player's shoulder. It is therefore advisable to carefully examine how and in which environment communication measures have the greatest impact on which consumers.
Memory through emotionsBarbara Evans and her team can use SST to measure various factors: whether a message is stored and remembered in long-term memory (long-term memory encoding), how relevant it is to the individual recipient (engagement), how strongly they feel when receiving it (emotional intensity), whether the content of the message attracts, repels or saddens them (approach/withdraw), how strongly it is perceived visually (visual attention) and whether the brand wins or loses (brand salience). "It is important to test different factors and link the measurement results with each other," says Evans. "For example, if a respondent remembers a key visual well, this initially appears to be positive - but it can also be because they feel repelled. Even then, the brain reacts very strongly. In this case, we need to correlate engagement, emotional intensity and approach/withdrawal. Only then do we really know what the observed reaction of the brain means." So a fire in the brain is not always a good thing. Sometimes it is better to extinguish it immediately.
The measurement results of the electrode cap also reveal whether viewers perceive and process a commercial more rationally or more emotionally. This is crucial for the selection of the environment in which a TV commercial or advertisement is subsequently placed. "We know from Richard Silberstein's research that emotionally decoded ads should be placed in emotionally decoded environments and rationally decoded ads in rationally decoded environments," says Evans. "That's why we also examined some potential environments for advertising placements with SST." Silberstein analyzed, for example, the American TV series "Desparate Housewives", which pokes fun at the everyday torments of the perfect housewife. How do you think the series is perceived by TV viewers? Emotionally or rationally? Wrong. You probably answered "emotional" spontaneously, like most respondents. But the correct answer is "rational", as Barbara Evans and her team found out. This means that media planners who place an emotionally decoded commercial during the commercial breaks of "Desperate Housewives" are giving away a large part of the impact of their commercial. Sounds like gray theory, but Silberstein has already been able to verify these research results in practice. Neurocommunication planning can therefore save money.
Less is moreThis was also the experience of Neuro Impact's first client, the car brand Mini, which belongs to the BMW Group. Mediaplus is already advising Mini on its media planning. At the end of 2008, the marketing department had two commercials available for the new convertible, a seven-second and a twenty-second spot. However, there was no clear preference in marketing as to which of the two commercials should be placed. A case for SST. "I suggested to our client that we test the effectiveness of the two spots using our new measurement method," reports Evans. Max Kalbfell, Head of Marketing Mini Germany, was enthusiastic about the idea. "We wanted to increase the efficiency of our communication, but not at the expense of creation. SST seemed to us to be a suitable measure to achieve this goal." So Neuro Impact put 150 test subjects under the electrode hood and presented them with both commercials. The result: the longer spot came out on top. "We were able to show that the short TV spot had significantly more potential in terms of remembering the core message and branding than the long one," reports Evans. "The channel planners were also pleased, as they can now create a longer on-air presence with the short but high-impact spot."
Max Kalbfell is also satisfied with the study: "The results were clear. We decided to show the shorter spot and target it at more people in order to create a greater presence. And we can even use such a short spot - it has been slightly revised and is now eleven seconds long - online, on mobile devices or as a vodcast." Mini Germany and Mini Switzerland are currently advertising with the short film. All other Mini locations have opted for the longer spot. The neuron-tested film is therefore not only a test of whether neurocommunication planning really works, but also a kind of precedent for Mini, to which many eager eyes within the Group are turning.
A future with nerves of steelDespite the positive experience, Mini does not want to send its entire communication through the Neuro Impact test. Other companies are sensing an opportunity: media companies have already expressed their interest in initial projects with Neuro Impact. Evans is also holding talks with national and international companies from various sectors. For ethical reasons, Neuro Impact rejects commissions to check communication measures aimed at children under the age of 14 and to carry out studies for the cigarette and arms industries.
One thing is clear: neurocommunication has potential. So much so that it could permanently change advertising and marketing. Neuro Impact is therefore continuing to refine its analysis tools. The role of mirror neurons, which generate feelings in the viewer when observing a process as if they were carrying out the action themselves, could also become significant for neurocommunicators in the future.
"The Mini example shows something else," adds Barbara Evans, "namely that creation and media planning have to work hand in hand. At present, media planners often don't even know the commercials or advertisements they are placing. But only if communication measures are precisely tailored to their media target environment can they have an optimal effect - and only then will the company save money. Reach and costs are not everything." When commercials and campaigns strike a chord with consumers, it's not just the brain that sparks.

SST - How does advertising really work?
Steady State Topography (SST) is the patented research method used by the Australian market research institute Neuro Insight to measure the effectiveness of communication measures. It was developed by Richard Silberstein, brain researcher and Professor of Neurophysiology at Swinburne University. Silberstein has been researching the impact of marketing and advertising for 30 years. In the SST analysis, the test subjects wear caps with electrodes that measure their brain activity, as well as special glasses. They are shown commercials, campaigns, campaign elements or logos and the brain's reactions are recorded during reception. Based on the activity of the individual brain regions, the researchers can read which campaign elements have an effect in which form in which media and on which consumers. Richard Silberstein has been using SST to analyze communication measures for around five years. He has already conducted studies for Allianz, Ferrero and Vodafone.
The Neuro Impact division of Mediaplus now offers the method exclusively in Germany, Austria and Switzerland. The Neuro-Check is suitable for the entire range of communication: from POS and packaging measures to commercials, campaigns and sponsoring activities to the testing of media channels and environments. As a result, SST can also be used to optimize strategic media planning. Neuro Impact works together with Silberstein's company Neuro Insight, particularly in the evaluation of research results. However, Neuro Impact also has its own research department. The analyses are carried out with at least 50 people; depending on the complexity of the question, more test subjects can be tested. A simple study takes one to two weeks, a complex one up to four weeks. The costs are in the five-figure range.
