项目摘要

The aesthetic perception of artworks is largely dependent on cultural norms and previous exposure to art objects (Leder, Belke, Oeberst, & Augustin, 2004). Nevertheless, it has been shown that certain properties of visual objects can be related to positive ratings on beauty in artworks. Therefore, one subfield within aesthetics research focuses on these formal aspects of the stimuli.Gustav Theodor Fechner is considered the founder of aesthetic science. He searched for objective properties that can be associated with perception of beauty (outer psychophysics, Fechner, 1876). He was one of the first scientists to directly measure objective properties of aesthetic stimuli. Along this line, recent studies focus on the investigation of statistical image properties that are considered to be relevant for human visual perception. For some years, Christoph Redies and I have applied digital analyses of statistical image properties. In several studies, we showed a relation of global image properties (spectral Fourier slope, anisotropy, self-similarity and complexity) with subjective ratings on beauty (e.g., Redies, Hasenstein, Denzler, 2007; Mallon, Redies, & Hayn-Leichsenring, 2014).In another approach, neuroscientists like Anjan Chatterjee have made highly interesting progress in connecting subjective beauty ratings with neurophysiological activities (inner psychophysics). It has been shown that aesthetic experiences are generally processed within brain areas that are usually associated with other tasks. On the one hand, depending on the type of aesthetic stimulus, domain-specific neuronal activities can be found in parts of the sensorimotor system, while on the other hand, the exposure to different beautiful stimuli leads to similar activation patterns within the emotion-valuation-system (Pegors, Kable, Chatterjee, & Epstein, 2014; Chatterjee & Vartanian, 2014).In the proposed project, Anjan Chatterjee and I are planning to investigate whether established global image properties correlate with neurophysiological activities. To this aim, we are planning three fMRI studies with different types of stimuli. We will relate the neuronal responses to landscape paintings, art portraits and abstract art paintings with their statitsical image properties. Special focus will be laid on specific areas of the sensorimotor system and the emotion-valuation-system. Therefore, the aim of the current proposal is to establish a link between outer and inner psychophysics.

艺术品的审美感知在很大程度上取决于文化规范和以前对艺术品的接触（Leder，Belke，Oeberst，& Augustin，2004）。然而，已经表明，视觉对象的某些属性可以与艺术品中的美的积极评级有关。因此，美学研究的一个分支集中在刺激的这些形式方面。古斯塔夫·西奥多·费希纳被认为是美学科学的创始人。他寻找与美的感知相关的客观属性（外部心理物理学，费希纳，1876年）。他是最早直接测量审美刺激的客观属性的科学家之一。沿着这条线，最近的研究集中在被认为是相关的人类视觉感知的统计图像属性的调查。几年来，Christoph Redies和我一直在应用统计图像属性的数字分析。在几项研究中，我们展示了全局图像属性（光谱傅立叶斜率，各向异性，自相似性和复杂性）与主观评分的关系（例如，Redies，Hasenstein，Denzler，2007; Mallon，Redies，& Hayn-Leichsenring，2014）.在另一种方法中，像Anjan Chatterjee这样的神经科学家在将主观美丽评级与神经生理活动（内在心理物理学）联系起来方面取得了非常有趣的进展。研究表明，审美体验通常在与其他任务相关的大脑区域内进行处理。一方面，根据审美刺激的类型，在感觉运动系统的某些部分可以发现特定领域的神经元活动，而另一方面，暴露于不同的美丽刺激导致情绪评价系统内相似的激活模式（Pegors，Kable，Chatterjee，& Epstein，2014; Chatterjee & Vartanian，2014年）。在拟议的项目中，Anjan Chatterjee和我正计划研究建立的全局图像属性是否与神经生理活动相关。为此，我们计划用不同类型的刺激进行三项fMRI研究。我们将把神经元对风景画、艺术肖像画和抽象艺术画的反应与它们的统计图像特性联系起来。将特别关注感觉运动系统和情绪评估系统的特定领域。因此，目前建议的目的是建立外部和内部心理物理学之间的联系。
