The Savanna Effect




        Like every other human appendage which has been shaped by evolution to perform a specific role, so too has the brain. Evolutionary psychologists argue however, that like our hands and feet whose form and function has remained relatively unchanged since the end of the Pleistocene epoch, the human brain and psychological mechanisms associated with it are also innately biased to perceive and respond within that very same environment. When assessing and attempting to explain human behaviour, this means that the average human brain still assumes that it lives in the African Savanna roughly 10,000 years ago. As a result, humans frequently have difficulty comprehending different entities and situations that did not exist in our ancestral environment. Evolutionary psychologist Satoshi Kanazwa of the University of London coined this phenomenon the ‘Savanna principle’, with his theory frequently cited to better explain the behaviour of modern day humans in a variety of processes and occupations, from microeconomics and architecture to marketing and advertising.

        Psychologists argue that as a result of millions of years of evolution, the human perceptual system is largely hardwired, with different visual scenes triggering varying affective states. For example, if early humans came across a stretch of turbulent water or a threatening predator, this triggered negative affective reactions. However, if a visual scene provided opportunities for survival or reproduction, positive affect would be experienced. Geographer Jay Appleton was one of the first to explore mans emotional relationship with the external environment. In Appleton’s theory he states that human beings’ preference for landscapes correlates with two environmental properties, prospect and refuge. The concept of prospect refers to elements within an environment that provide information, such as a landmark to navigate from or hill from which to inspect the surrounding area. In addition, refuge refers to environments that provide shelter, protecting against predators and inclement weather. In short, humans prefer landscapes which consist of a balance of these two environmental properties.



Optus 'Harmony' (2005)

      The African savanna, which is claimed to be the environment in which early humans spent a substantial part of their evolutionary history, appears to display an ideal mix of both prospect and refuge. Scattered trees provide refuge and shelter, while the openness of savannas facilitate the detection of predators and potential game. In addition, most people across cultures and geographic regions instinctively find clear flowing water more beautiful than stagnant water, grassy landscapes more attractive than arid landscapes, and mountains and hills in the distance more attractive than flat terrain. Ultimately, during our evolution certain features of landscape were more adequate for survival and reproduction than others and due to the importance of recognising these visual features, humans have evolved to associate subtle but non-trivial affective states with external environmental properties.

      Importantly, theories regarding human preferences to visual scenes are not limited to those of the sparse African savanna. Kaplan and Kaplan suggest an expanded matrix of visual preference whereby, while people are still largely attracted to environments that are prehistorically survivable, four structural properties of aesthetic evaluation; coherence, complexity, mystery and legibility, also enables an assessment of human preferences for more modern environments. Kaplan and Kaplan describe coherence as the degree to which a scene hands together (the higher the degree of coherence the greater the preference for the scene), legibility or distinctiveness as enabling the viewer to understand or categorise its contents, complexity or the degree of variety within a natural scene, and mystery, the degree to which a scene contains hidden information which entices the viewer to find our more information. In this model, coherence and legibility relate to our understanding of the environment (being able to comprehend what is going on), while complexity and mystery can be considered as aspects of the environment to which someone may be motivated to explore more deeply.



A long winding road evokes mystery and a desire to explore further.

      While evolutionary and environmental psychology is gaining credibility in explaining human behaviour, it is also commonly validated in assessing consumer behaviour and the influence of advertising. Visual representations of nature are widely used in both print and TV advertising to evoke positive emotional associations. However, one thing that our ancestors did not experience was watching TV. In fact, research has outlined that people who spend more time watching particular TV shows are actually more satisfied with their social life and friendships, just as they are if they have more friends. Ultimately, all visual scenes our ancestors saw were real and therefore, when it comes to materials on television, the Savanna Principle tells us that at a deeper level the human brain is tricked and comprehends these images as if they are in natural environment. And, just as humans find it difficult to emotionally distinguish between real friends and those on TV, for brands and products that emulate real and ‘idealistic’ landscapes, the use of certain images will also have a positive impact on consumer associations.



Pure Blonde (2007)

       In a recent Spanish study which assessed consumer attitudes towards advertising it was reported that people were more favourable in their perceptions of ads containing natural scenery than those depicting urban environments or vegetation free scenes, with ads that contained images of free flowing clean water and lush green vegetation also leading to the highest consumer attitudes towards the ad and brand. Thus, through repeated exposure of cohesive advertising images, brands clearly may gain positive emotional conditioning, with brands able to profit off their alignment with idealistic natural settings.

Practical Implications:

      Evolutionary psychology research indicates that marketers who decide to leverage off images of the natural environment can influence the affective states of their consumers. The Savanna Principle provides a theoretical framework indicating that manipulating or tailoring natural images to coincide or deviate from our innate visual preferences, while a seemingly subtle production change, may have non-trivial influences on consumer’s emotional perception of a product, potentially influencing attachment to a product or even brand recall.


        Clearly, it is important for marketers and advertisers to account for, or at the very least acknowledge, innate reactions that have stemmed from our ancestral past. Research indicates that these affective states are foundational to our conscious thinking, and to benefit from thousands of years of evolution, marketers may tailor their campaigns to capitalise on these implicit preferences. By aligning brands and products to content which has been found to influence our affective states automatically and efficiently, such as savanna-like natural scenes, marketers and advertisers may benefit.

Evolution and Advertising - Part 3: Pop ups in our past.


Despite the mass of advertising that the average consumer faces every day, it is clear that some messages constantly grab our attention irrespective of our interest.

So why are some forms of advertising particularly salient and robust against the noise of mass marketing? One answer is attentional capture.

Cognitive psychologists argue that at any given time, people have limited resources to devote to all possible tasks and incoming information. In regards to human vision, most agree that sudden movements and bright colour tends to naturally draw our attention, perhaps involuntarily. This is known as attentional capture. It has been hypothesised that this prioritising of attentional resources to new visual objects has evolved due to predatory associations. It makes obvious sense that our attention is drawn to new visual objects to assess them for danger or potential threats.

Literature outlines that there may be two separate mechanisms at work when analysing visual attention, with attentional resources captured in a ‘goal directed’ fashion, whereby attention is directed based on a the task at hand, or involuntarily in a ‘stimulus driven’ fashion’ when attention is draw to an object that is unrelated to a potential task. While modern day marketers often aim to capture our attention through sophisticated, aesthetically pleasing and humorous advertising, it is apparent that campaigns are also developed to capitalise upon our raw, stimulus driven impulses.

Research illustrates that attention is broadly allocated to multiple elements within a visual scene, not simply by their location, but according to their position and status as noted in preattentive visual organisation. Attention is subsequently provided to aspects of our visual scene for which it deems to be most relevant. It has been reported that the abrupt appearance of objects, apparent visual movement and luminance changes are highly prioritised within this attentional hierarchy.

Studies indicate that the abrupt onset of a visual object captures attention automatically. These studies reveal that even when observers are attending to other tasks, an abrupt visual onset of an object is processed first. Thus, these onsets have been argued to capture our attention in a purely stimulus driven fashion. Internet pop-up advertising capture similar attentional resources to those of abrupt onsets. These messages draw us away from the task at hand to apply our attention, even if only for a moment, to an advertising message or brand. This is not necessarily because we are interested in what the advertisement is saying, but rather that we are hard wired to attend to them.




Theories regarding the perception of luminance also outline that a rapid luminance increase is detected by visual mechanisms which are selectively tuned to the onset of luminance signals. These signals are transferred to higher level cognitive mechanisms, indicating the importance of this change in luminance and that attention must be directed towards it. Similarly to the abrupt onset of a new object, an increase in luminance also captures our attention being perceived as a new visual object. It goes without saying that a flashing light from a police car in our rear view mirror captures our attention, but so too do flashing neon signs and advertisements at the football. With the rapid increase of luminance, a new visual object is perceived, and similarly to abrupt onsets, we are momentarily captivated.




Movement within a visual scene is also detected easily by humans, with unexpected object movement also reported to capture our attention. If we think about it, it is not uncommon to wave our arms to capture someone’s attention within a crowd, or wave a flag to slow down F1 drivers after a crash. Well maybe that’s a little uncommon, but overall, movement detection is robust. Interestingly, research indicates that visual movement is most salient when it may be used to indicate the location of visual targets, while not as successful in capturing our attention if it fails to predict a targets location. This also makes sense in evolutionary terms. It would not benefit us to attend to irrelevant movement cues, while it makes perfect sense for us to detect the location of a predator in the undergrowth, as indicated by a brief calculation of these cues.




Outdoor digital billboards and online banner advertising heavily employ visual motion to draw consumer attention to a message or brand. Despite consumers having to attend to the road while driving, to the players while watching sport or to the rise and fall of the stock market on the computer, we are constantly interrupted to notice potentially irrelevant advertising. When watching digital advertising surrounding major sporting events it is clear to see how cues of motion have been used to draw our attention. Brand messages or logos fly across the billboard, not unlike an advancing threat, engaging our attention and visual resources long enough to recognise the brand and create a visual impression, but not to decipher a complex message. On the internet, banner advertising is constantly in motion, with brands, logos and products dropping in from all areas, again diverting our attention for split second.

Practical Implications:

While companies often employ the use of attentional capture via the abrupt onset of objects, sudden increases in luminance and the implementation of movement cues, it is also apparent that the effectiveness of such advertising is also waning as they begin to over-saturate the market. Studies report that the more intrusive an advertisement is perceived, the less effective it will be. It appears that consumers are starting to block their innate impulses in order to increase productivity and reduce distraction, especially when advertising is perceived as highly intrusive to the task at hand.

So, how do we capitalise on our innate impulses, while also reducing advertising intrusiveness? One solution may be congruency. Studies which have focused primarily on web based advertising have noticed that the more congruent the advertising is to the current web page, the less the viewer will actively block the attentional capture and the more likely they are to retain its information. Particularly it has been reported that viewers are more likely to retain the information from the advertisement if it employs the same colour palette as that of the web site. I noticed a similar example on the television the other evening while watching the Rugby Union, where Mercedes cleverly advertised their company in a pop-up message that was so congruent with the current context, that I thought it was a player profile or notification of a players substitution. It was not until I had read and comprehended the message, that I realised I had been duped!




Ultimately, in a busy and noisy world, where mass marketing is king, the fight for attentional resources is very real. In shaping and implementing campaigns, we must acknowledge the limited information capacity system of humans, but also be aware of more modern annoyances. This is a fine line to tread. Nevertheless, there is no doubt that to achieve success via maximal brand recognition and information retention, modern day marketers must capitalise on human beings innate reflexes to attend to potentially relevant information in a purely stimulus driven manner. This is no smash and grab job however, marketers must also act creatively and unobtrusively to obtain maximal attentional resources, brand recall and positive brand recognition.

Evolution and Advertising- Part 1: Sex Sells




It has often been said that sex sells, but rarely have we asked why?

It goes without saying that sexualised marketing is successful in capturing our attention. There is no doubt that sexual cues hold a unique salience when compared to other non-sexual cues. Sexual cues have been found to be so prominent, that they are salient for women who have reportedly low sexual desire (Conaglen & Evans, 2006). In an interesting study, Spiering et al. (2003) also report that responding to sexual stimuli in a task was influenced by sexual priming, while responding to non-sexual stimuli was not. It is logical that this unique salience of sexualised cues stems from our evolutionary origins, with the detection of such signals being vital in preparing to engage or indeed inhibit sexual behaviour (Conaglen & Evans, 2006). The ability to attend and respond to this information has clearly been fundamental in prolonging the existence of our species throughout time.

Further delving into the intricacies of sexual cues, research has illustrated that nonverbal cues such as eye contact and provocative clothing can heighten perceived sexual interest (Muehlenhard et al., 1986) and as a result, may be more salient than imagery with objects of sexual desire alone. Interestingly, it has also been found that the use of different colouring also has a significant aphrodisiacal effect. A recent study conducted by the University of Rochester (2008) discovered that women wearing red were rated as being more attractive and sexually desirable by men than the exact same women wearing different colours. One theory is that these biases originated in our primate ancestors, where baboons and chimpanzees redden conspicuously when nearing ovulation. We can see from the advertisement above, that a scantly clad Cindy Crawford, sporting a bright red dress, is engaging in clear eye contact with the observer, provocatively capturing our attention and maybe even selling some Pepsi. Clearly there are numerous non-verbal factors that may alter perceived sexual interest associated with an image, subsequently increasing its salience.


While it is relatively easy to understand that men and women may attend to and even be engaged in sexual advertising, an expanded view into the psyche of male and female sexuality has exposed even more information that can be utilised to benefit marketing campaigns.

Sexual Strategies Theory (SST) offers an account of the adaptive problems our ancestors confronted during the course of competitive evolution and presents a view of sexual psychology that has evolved as adaptive solutions (Buss, 1998). In short, STT indicates that men are only constrained by the number of fertile women they can inseminate (Buss & Schmitt, 1993), while women who invest and risk more in sexual engagement, require a degree of commitment and additional resources from a mate. Basically, men want casual recreational sex, while women require emotional intimacy and resource commitment.

In close adherence to SST, associations between evolutionary adaptation and contemporary advertising have been reported. Specifically, Dahl et al. (2009) report that women’s typical dislike of sexualised advertising is softened when the ad can be interpreted as commitment related. Thus, correlated more strongly with the underlying strategies of female sexuality. The male underware model above is a perfect example of this, his expression and gesture on the bed symbolising intimacy and a degree of commitment. Colour it appears, is not important.

Ultimately, the cliché that sex sells may be an oversimplification. It appears that it is not simply the evolutionarily relevant salience of sexual cues which may be utilised in advertising, but that further manipulation of the forms of sexual images that are included are also highly relevant when aiming to engage and attract different markets. When used appropriately however, it appears that sex may be able to sell just about anything!
