关于艺术感知和评价的神经心理学知之甚少。大多数神经心理学的艺术方法都集中在艺术生产，并一直轶事和定性。如果这个领域要发展，就迫切需要定量方法。在这里，我们结合联合收割机的定量方法来评估的艺术与现代体素病变的神经网络映射方法，以确定大脑行为的关系，在艺术知觉。我们假设，对艺术的不同属性的感知可能会被大脑不同区域的损伤所破坏。20名右半球受损的受试者被给予艺术属性评估，该评估旨在量化视觉艺术的描述性属性的判断，每个受试者对24幅绘画进行6个概念属性的评估（消耗准确性，抽象性，情感，象征主义，现实主义和生命力）和6个感知属性（深度、色温、色彩饱和度、平衡、笔触和简洁）以及他们对这些绘画的兴趣和偏好。根据与30名年龄匹配的健康参与者的组平均评分的相关性，获得每个脑损伤参与者的每个属性的偏差分数。右半球损伤影响了参与者对抽象性、准确性和中风质量的判断。损害额顶叶和侧颞叶皮层的不同部分内的区域产生的偏差，在六个概念属性（抽象性，象征性，现实主义和生命）的判断。在正式属性中，只有深度受到下前额叶损伤的影响。没有任何脑损伤区域与兴趣或偏好判断的偏差有关。艺术品中概念属性和形式属性的感知可能部分地彼此分离，并与评价性判断分离。更一般地说，这种方法证明了定量方法对艺术神经心理学的可行性。
Little about the neuropsychology of art perception and evaluation is known. Most neuropsychological approaches to art have focused on art production and have been anecdotal and qualitative. The field is in desperate need of quantitative methods if it is to advance. Here, we combine a quantitative approach to the assessment of art with modern voxel-lesion-symptom-mapping methods to determine brain behavior relationships in art perception. We hypothesized that perception of different attributes of art are likely to be disrupted by damage to different regions of the brain. Twenty participants with right hemisphere damage were given the Assessment of Art Attributes, which is designed to quantify judgments of descriptive attributes of visual art. Each participant rated 24 paintings on 6 conceptual attributes (depletive accuracy, abstractness, emotion, symbolism, realism, and animacy) and 6 perceptual attributes (depth, color temperature, color saturation, balance, stroke, and simplicity) and their interest in and preference for these paintings. Deviation scores were obtained for each brain-damaged participant for each attribute based on correlations with group average ratings from 30 age-matched healthy participants. Right hemisphere damage affected participants' judgments of abstractness, accuracy, and stroke quality. Damage to areas within different parts of the frontal parietal and lateral temporal cortices produced deviation in judgments in four of six conceptual attributes (abstractness, symbolism, realism, and animacy). Of the formal attributes, only depth was affected by inferior prefrontal damage. No areas of brain damage were associated with deviations in interestingness or preference judgments. The perception of conceptual and formal attributes in artwork may in part dissociate from each other and from evaluative judgments. More generally, this approach demonstrates the feasibility of quantitative approaches to the neuropsychology of art.
