Abstract This paper presents some findings of an Is it possible to identify the compositional characteristics ongoing on the and aesthetic of an artwork, that are able to activate the brain areas appreciation of the artworks, based for the first time on the responsible for the Beauty recognition, inducing the use the most popular social network: Facebook. Exploiting Aesthetic Pleasure in the viewers? Maybe all of us are driven the system of “like” and “share”, on which Facebook is by a specific form of aesthetic determinism when we admire based, thousands of artwork images were submitted to a and appreciate an artwork? If we were able to predict the sample of over 10,000 users worldwide. Through the metrics aesthetic preferences of the public towards an artwork, analysis related to the aesthetic preferences expressed by maybe could we talk about Aesthetic Precognition? the users, it was observed they are inclined to react the same According to recent studies in the field of , way towards certain visual stimuli coming from artwork the process of aesthetic appreciation by the perceivers has a images: specific compositional characteristics of the neurophysiological basis [1,2]. Comparing the findings of artworks are able to influence the aesthetic preferences of the these studies with the Processing Fluency theory of aesthetic viewers towards some artworks rather than others. The pleasure [3], that emphasizes the interaction between the steady repetition of aesthetic preferences related to same perceiver and an object, focusing on the effects of objective compositional elements present in the artworks allowed to stimulus attributes on perceived Beauty, we hypothesized predict the subsequent aesthetic choices by the viewers that Beauty perception and Aesthetic Pleasure of the viewers towards not yet posted artworks. We identified some of these are predetermined by specific visual characteristics of the responsive elements, which would be able to activate the artworks. Based on this insight, we analyzed the aesthetic Beauty recognition and the Aesthetic Pleasure in the preferences expressed by a wide sample of viewers towards perceivers. In this way it would be possible to develop an several artwork images posted on Facebook: it was noted Aesthetic Algorithm able to identify the share of Beauty that most of viewers reacts the same way in front of precise required to activate the Aesthetic Pleasure, by introducing visual stimuli. The presence of specific compositional specific responsive elements in the artworks with the aim of elements within the artworks would be able to influence the predicting, and also predetermining, the viewers reactions. aesthetic judgment: this would not be subjective and based The knowledge of the perceptual mechanisms capable of on inborn or acquired preferences, but resides in the features activating the Aesthetic Pleasure might allow to predict and of the viewed object, that stimulate the Aesthetic Pleasure of influence beforehand the aesthetic preferences of viewers the viewer. So the viewer’s brain would be adapted to these toward the artworks, with many implications for the current hedonically marked features of the artworks. Art Market. We described this predictive analysis of Here we anticipate some findings of an empirical study, aesthetic appreciation of the viewers as Aesthetic still in progress, that we are conducting in innovative and Precognition. unconventional way through the use of the most popular social network (Facebook), in order to explore a new field of Keywords , Neuroesthetics, Empirical investigation based on the intersection among Psychology of , Perception, Precognition, Facebook Perception, Neuroesthetics and Information Technology. We decided to use Facebook because it is currently the

For this reason a more appropriate screening is needed. 2. Materials and Methods To get our reference sample, we opened three identical Facebook profiles, on which we posted every day for three 3. Results years, images depicting many works of Contemporary Art, The experiment has confirmed that the viewers, with no specifically in the form of and installations, significant differences between the expertise of each created through many different artistic techniques by analyzed cluster (art expert or non-expert) and their specific numerous from around the world. culture or nationality, were somehow attracted by the same The analyzed sample was made up of contacts aggregated kind of images and by the same combinations of to each profile, which have been divided into two clusters, compositional elements (shapes, colors, spatial layout, etc.), based on the level of their expertise in art: naïve viewers (art reacting the same way to identical aesthetic stimuli: in fact, untrained), and art experts (artists, curators, critics, when we proposed afterwards other different artwork images gallerists), both of them coming from around the world, to in accordance with the aesthetic preferences previously whom thousands of artwork images were submitted with the given by the viewers, it was possible to predict rather aim to evaluate personal aesthetic preferences of the viewers, accurately their possible aesthetic choices towards the expressed through the “like” and “share” system, typical of artworks before these were shown. Facebook. As all profiles reached the limit of 5,000 personal Although there was no contextualization of the artworks contacts (imposed by the social network), due to the large inside a three-dimensional exhibition space, such as an art number of connection requests coming from new friends gallery or a museum (in fact images were shown in a attracted by the images, our research has focused on a sample bi-dimensional mode through the computer screen), anyway of over 10,000 users worldwide, unaware of being involved the experiment gave back a rather accurate idea of which into the experiment. In the course of three years, we should be the responsive compositional elements present submitted over 15,000 artwork images (about 15 per day), within the artworks, that would be able to activate the Beauty alterning images in which specific visual characteristics to be recognition and stimulate the Aesthetic Pleasure in the analyzed were present, with others images in which those perceiver, unlike the Functional Magnetic Resonance characteristics were absent, in order to identify the aesthetic Imaging (fMRI), which has allowed only to describe until characteristics of artworks preferred by the viewers. In this now the brain modifications in Art viewing and identify the regard we have analyzed carefully metrics, analytics and cerebral areas connected to the aesthetic appreciation under folksonomies provided by the social network, related to the the influence of specific visual stimuli [4,5], however aesthetic preferences of the viewers, that is the quantitative without making an in-depth study about the influence of data obtained in terms of “like” and “share” by the users, as some specific responsive elements present in the artworks, well as the user engagement percentages achieved by each that should be able to activate the perception of Beauty, artwork image, which expressed rather accurately the inducing a specific aesthetic behavior by the public. aesthetic orientation by the viewers, analyzing and Indeed, during the experiment, it was possible to isolate segmenting the visual characteristics of each artwork, some well-defined categories of compositional elements identifying the occurrences of specific compositional within the artworks that, when combined in a precise way, elements, and comparing them to the peaks of aesthetic should activate the Beauty recognition and drive the preferences determined by the viewers’ choices. aesthetic preferences of perceivers towards artworks that The most interesting parameter considered during the meet such compositional characteristics, so that during the experiment was the total engagement: in the metrics analysis experiment we were able to predict with reasonable accuracy of the preferred artwork images, this parameter represents which artworks the public would been preferred. In fact, the amount of all users interactions that each artwork image thousands of artwork images having those identified has been able to generate. It is obtained by the algebraic sum compositional characteristics were subsequently reproposed of “like”, “share”, spontaneous comments and posts by the several times, and the preferences of the viewers were viewers about the posted artwork images on Facebook exactly what we expected, confirming that such timeline. In fact, as a user preference may be influenced by compositional items present within the artworks are able to the aesthetic preferences of users majority, to analyze only activate the onset mechanisms of Aesthetic Pleasure in the “like” variable may be restrictive and misleading in this perceiver, stimulating the brain areas connected to the research. Therefore, another important research parameter to Beauty recognition: they seem to influence the aesthetic be considered is the virality of “like” diffusion, that during preferences of the viewers, inducing specific reactions in the 250 An Introduction to the Aesthetic Precognition: Threat or Opportunity for Contemporary Art?

As recently demonstrated by in-depth investigations repetition of the same aesthetic choices towards certain conducted through the use of techniques artwork groups showed that there are some specific (fMRI), Art viewing stimulates the right hemisphere and compositional elements inside the artworks able to activate of the brain [10,11], but we have observed the Beauty appreciation and Aesthetic Pleasure in all the that the above compositional elements are able to induce perceivers. The responses provided by the viewers towards precise aesthetic behaviours, influencing the aesthetic the above compositional elements appeared to be similar for choices and driving the aesthetic preferences of the viewers each individual, so that it was possible to predict the towards some artworks rather than others, activating so the following aesthetic preferences of the public towards not yet Beauty recognition and the Aesthetic Pleasure in the submitted artworks. We have defined such phenomenon as perceivers. We even believe that, if such elements were Aesthetic Precognition, that is the possibility to predict in present all together in a specific display context, and were advance the aesthetic preferences of a viewer towards an shown to neurophysiological predisposed individuals, they artwork group before this was exhibited, or, for those could be able to cause a perceptive shock or aesthetic individuals who learned to recognize the responsive breakdown in the perceiver, known as Stendhal syndrome compositional elements of an artwork, that specific ability to [12,13]. identify beforehand the structures of Beauty inside an artwork: in fact, the knowledge of these responsive structures should make possible to foreknow what may be the aesthetic appreciation of a viewer towards an artwork. The Aesthetic Precognition has nothing paranormal or esoteric, because that is connected to neurophysiological and biochemical workings of the brain and to human perception dynamics, according to which the humans realize the Beauty concept, that would be only apparently subjective, and are attracted or fascinated by a given artwork rather than another [17,18]. Probably, the concept of Beauty, that forms and organizes the human perceptional experience relating to the Art, is biologically and genetically predetermined, like if it was inscribed by ever in the human DNA. In our opinion, the process of brain assimilation of prototypical structures of Beauty could be supported by the mirror neurons, that have fixed artwork images introjecting and storing them like a computer memory, through repeated exposures over time. It may be that, in the course of human evolution, this psychobiological process has helped to build a neuropsychic apparatus of Beauty recognition, a sort of aesthetic memory based on the viewer’s experiences, that corresponds to a specific prototypicality system, supporting the development of brain receptors of Aesthetic Pleasure, that now would be able to react rather automatically and in reflected way to visual stimuli coming from the Art viewing, making predictable the aesthetic reactions by the perceivers: Beauty Anish Kapoor (2009). Ascension (Red). appreciation would be therefore a selective and hereditary Figure 3. Red color trait of the human evolution [19,20]. But the inheritance of an genetic aesthetic memory is yet to be proven. As argued by E. H. Gombrich[14], the factors that The Aesthetic Precognition is basically a specific form of determine the aesthetic experience are inherent in our aesthetic determinism, or aesthetic perceptional conditioning, biological inheritance, even if we are unable to give them a through which the preference of an individual towards an conscious explanation. Towards specific visual stimuli, the artwork rather than another may be predicted or even aesthetic appreciation seems to activate and resonate in the predetermined: according to this perspective, it would be same way in all the perceivers worldwide [15]: it’s like if the possible to know in advance if a viewer will like or not a viewer, by admiring an artwork having those specific given artwork, or create some artworks able to activate or characteristics, discovered something already known, a kind induce for sure the Aesthetic Pleasure in the viewers, of immanent principle of Beauty: C. G. Jung[16] called this influencing beforehand the aesthetic appreciation of the principle as Archetype. In fact, we have detected the same public, or driving in a predetermined way their aesthetic typology of aesthetic appreciation by the most viewers in preferences towards certain artworks instead of others. both analyzed clusters (expert or non-expert in art) exposed The ability of influence beforehand the aesthetic judgment to the submitted artwork images: the systematic and steady could give rise to a new form of Aesthetic Cognitivism, based 252 An Introduction to the Aesthetic Precognition: Threat or Opportunity for Contemporary Art?

The predictive analysis of the artworks’ Beauty, based on the knowledge of compositional elements 4. Discussion capable of activating the Beauty recognition and stimulating For centuries man questioned about the concept of Beauty the Aesthetic Pleasure in the perceivers, might allow the and its nature, but probably Beauty is just based on the brain artists to operate according to the Aesthetic Precognition, to neural structures, that can now be explored and analyzed in such an extent to modify their artistic in order to depth [21-23]: if Neuroesthetics has made possible to influence the aesthetic preferences of the viewers. So it identify - through the neuroimaging technologies such as the would be possible to develop a Precognitive Aesthetics based fMRI - the brain areas activated during the Art viewing on the predetermination of aesthetic tastes and preferences of process [24,25], the investigation we are still carrying out is the public towards the artworks, but also to build a specific allowing to identify the aesthetic orientation of the viewers technique of aesthetic persuasion able to provide the artists with respect to specific responsive compositional elements with the know-how through which activating the brain areas present within the artworks, that seem can stimulate the involved in the Beauty appreciation, and inducing the emergence of Aesthetic Pleasure in the perceivers. This desired aesthetic reaction in the perceivers: the knowledge of perceptual process was highlighted by the aesthetic the brain reaction mechanisms towards specific visual preferences of the viewers related to thousands of artworks stimuli, such as shapes or colours inside the artworks, would submitted during the experiment, constantly repeated with allow to condition the aesthetic appreciation and drive the respect to specific visual stimuli: to that are certainly aesthetic preferences of the public in predetermined way. connected to psychobiological mechanisms of perception, For this reason, the process of artistic creativity, which have become Beauty-sensitive in the course of human unaffected expression of spontaneous emotions, could turn evolution [26-28]. into a specific ability to catch in a intentional way the aesthetic preferences of the public, activating the desired reactions by the viewers: so the ’s work would turn into aesthetic predetermination, by creating pieces of art predestined to be beautiful.
