Lateral Orbitofrontal Cortex Involvement in Initial Negative Aesthetic Impression Formation

It is well established that aesthetic appreciation is related with activity in several different brain regions. The identification of the neural correlates of beauty or liking ratings has been the focus of most prior studies. Not much attention has been directed towards the fact that humans are surrounded by objects that lead them to experience aesthetic indifference or leave them with a negative aesthetic impression. Here we explore the neural substrate of such experiences. Given the neuroimaging techniques that have been used, little is known about the temporal features of such brain activity. By means of magnetoencephalography we registered the moment at which brain activity differed while participants viewed images they considered to be beautiful or not. Results show that the first differential activity appears between 300 and 400 ms after stimulus onset. During this period activity in right lateral orbitofrontal cortex (lOFC) was greater while participants rated visual stimuli as not beautiful than when they rated them as beautiful. We argue that this activity is associated with an initial negative aesthetic impression formation, driven by the relative hedonic value of stimuli regarded as not beautiful. Additionally, our results contribute to the understanding of the nature of the functional roles of the lOFC

When Art Moves the Eyes: A Behavioral and Eye-Tracking Study

The aim of this study was to investigate, using eye-tracking technique, the influence of bottom-up and top-down processes on visual behavior while subjects, na \u308\u131ve to art criticism, were presented with representational paintings. Forty-two subjects viewed color and black and white paintings (Color) categorized as dynamic or static (Dynamism) (bottom-up processes). Half of the images represented natural environments and half human subjects (Content); all stimuli were displayed under aesthetic and movement judgment conditions (Task) (top-down processes). Results on gazing behavior showed that content-related top-down processes prevailed over low-level visually-driven bottom-up processes when a human subject is represented in the painting. On the contrary, bottom-up processes, mediated by low-level visual features, particularly affected gazing behavior when looking at nature-content images. We discuss our results proposing a reconsideration of the definition of content-related top-down processes in accordance with the concept of embodied simulation in art perception

The Observing facet of trait mindfulness predicts frequency of aesthetic experiences evoked by the arts

Mindfulness can foster an enhanced sensitivity to internal and external impressions, which could result in heightened subjective responses to works of art. So far though, very little is known about the connection between mindfulness and aesthetic responses to the arts, therefore the current study aimed to investigate whether there was an association between trait mindfulness and how often people report aesthetic experiences. We hypothesized that the Observing facet of mindfulness would positively predict the self-reported frequency of aesthetic experiences (aesthetic chills, feeling touched, and absorption). Participants in an online study (N = 207) completed the Five Factor Mindfulness Questionnaire, an Aesthetic Experiences scale in relation to the area of the arts a participant encountered most frequently in their daily life, and a measure of aesthetic expertise. Controlling for aesthetic expertise and sex, linear regression revealed that the Observing facet of mindfulness was positively associated with aesthetic experience, as predicted. Non-reactivity positively predicted aesthetic experience, while Non-judging was negatively associated with aesthetic experience. Potential explanations for the association between these three facets of trait mindfulness and aesthetic responses are discussed in relation to information-processing models of aesthetic experience. The findings provide preliminary support for the premise that levels of dispositional mindfulness are associated with the frequency of intense emotional responses to the arts, and recommendations for further research studies are outlined

Multiple dimensions of biodiversity drive human interest in tide pool communities

Abstract Activities involving observation of wild organisms (e.g. wildlife watching, tidepooling) can provide recreational and learning opportunities, with biologically diverse animal assemblages expected to be more stimulating to humans. In turn, more diverse communities may enhance human interest and facilitate provisioning of cultural services. However, no experimental tests of this biodiversity-interest hypothesis exist to date. We therefore investigated the effects of different dimensions of animal biodiversity (species richness, phyletic richness and functional diversity) on self-reported interest using tide pools as a model system. We performed two experiments by manipulating: (1) the richness of lower (species) and higher taxonomic levels (phyla) in an image based, online survey, and (2) the richness of the higher taxonomic level (phyla) in live public exhibits. In both experiments, we further quantified functional diversity, which varied freely, and within the online experiment we also included the hue diversity and colourfulness arising from the combination of organisms and the background scenes. Interest was increased by phyletic richness (both studies), animal species richness (online study) and functional diversity (online study). A structural equation model revealed that functional diversity and colourfulness (of the whole scene) also partially mediated the effects of phyletic richness on interest in the online study. In both studies, the presence of three of four phyla additively increased interest, supporting the importance of multiple, diverse phyla rather than a single particularly interesting phylum. These results provide novel experimental evidence that multiple dimensions of biodiversity enhance human interest and suggest that conservation initiatives that maintain or restore biodiversity will help stimulate interest in ecosystems, facilitating educational and recreational benefits

Reader responses to literary depictions of rape

This study explored reader responses to different literary depictions of rape. Four literary excerpts were used and divided as aesthetic versus nonaesthetic (style) and allusive versus explicit (detail). The general question was how would readers react to literary fragments depicting rape and whether the level of aesthetics and the level of explicitness influenced readers' thoughts and feelings. An open-ended question asked readers to report how the style had influenced their thoughts and feelings, whereas 7-point scales addressed the following variables: experienced distance, perceptions of realism and of beauty, emotional versus intellectual reaction, empathy, tension, and arousal. In a 2 (detail: explicit vs. allusive) × 2 (style: aesthetic vs. nonaesthetic) within-participant design (N = 34), gender functioned as a between-participants variable. Results indicate that the personal tendency to feel engaged with fiction overrides effects of aesthetics and explicitness. Principal-components factor analysis suggests that readers who are easily engaged with the characters feel unsettled when reading rape scenes they find brutal and intellectualize to handle these feelings. These “high empathizers” are not likely to be detached or to appreciate the fragment negatively: Once absorbed, they will try to take something positive even from an unsettling experience

Deep Convolutional Embedding for Painting Clustering: Case Study on Picasso's Artworks

Clustering artworks is a very difficult task. Recognizing meaningful patterns in accordance with domain expertise and visual perception, in fact, can be extremely hard. On the other hand, applying traditional clustering and feature reduction techniques to the highly dimensional raw pixel space can be ineffective. To overcome these problems, we propose to use a deep convolutional embedding clustering framework. The model simultaneously optimizes the task of mapping the input pixel data to a latent feature space and the task of finding cluster centroids in this latent space. A quantitative and qualitative preliminary study on a collection of artworks made by Pablo Picasso shows the effectiveness of the model. The proposed method may assist in art-related tasks, in particular visual link retrieval and historical knowledge discovery in painting datasets

THE NEURAL BASIS OF THE HEDONIC DIMENSION OF AESTHETIC EXPERIENCE.

In this review, I provide an overall description of the findings obtained from neuroimaging studies aimed at investigating the neural substrates underpinning aesthetic experience when viewing masterpieces of Classical art. In particular, I here argue the idea that aesthetic experience is hallmarked by a hedonic response to the stimuli. This response would be triggered, according to our proposal, by integration of emotional and cognitive processes at the level of the right insular cortex and, more specifically, of its anterodorsal sector. I then discuss the recent results suggesting that the hedonic quality characterizing aesthetic experience for artworks is absent when aesthetically appraising biological non-artist stimuli
