Neuroaesthetic research suggests that aesthetic appreciation results from the interaction between the object perceptual features and the perceiver's sensory processing dynamics. In the present study, we investigated the relationship between aesthetic appreciation and attentional modulation at a behavioural and psychophysiological level. In a first experiment, fifty-eight healthy participants performed a visual search task with abstract stimuli containing more or less natural spatial frequencies and subsequently were asked to give an aesthetic evaluation of the images. The results evidenced that response times were faster for more appreciated stimuli. In a second experiment, we recorded visual evoked potentials (VEPs) during exposure to the same stimuli. The results showed, only for more appreciated images, an enhancement in C1 and N1, P3 and N4 VEP components. Moreover, we found increased attention-related occipital alpha desynchronization for more appreciated images. We interpret these data as indicative of the existence of a correlation between aesthetic appreciation and perceptual processing enhancement, both at a behavioural and at a neurophysiological level.
神经美学研究表明，审美欣赏是对象知觉特征与知觉者感觉加工动态之间相互作用的结果。在本研究中，我们从行为和心理生理水平探究了审美欣赏与注意力调节之间的关系。在第一个实验中，五十八名健康被试者完成了一项视觉搜索任务，其中包含空间频率更高或更低的抽象刺激，随后被要求对图像进行审美评价。结果表明，更受欣赏的刺激的反应时间更快。在第二个实验中，我们在暴露于相同刺激时记录了视觉诱发电位（VEPs）。结果表明，仅在更受欣赏的图像中，C1 和 N1、P3 和 N4 VEP 成分增强。此外，我们发现，对于更受欣赏的图像，与注意力相关的枕部 alpha 去同步化增加。我们将这些数据解释为表明审美欣赏与知觉加工增强之间存在相关性的证据，这种相关性既存在于行为层面，也存在于神经生理层面。
