When appreciating a painting, people often classify it into a style. The extent to which the painting is regarded as a typical example of the style is called its style prototypicality. The authors propose a method of quantifying style prototypicalities and conduct an experiment to validate this method using the drift rate parameter of the drift diffusion model. This parameter is calculated using participants’ decision-making response times. The authors find a positive correlation (r = .88, p < .001) between the drift rates and the quantified prototypicalities for the paintings used in this study, confirming the psychological appropriateness of the proposed quantification method.

人们在欣赏一幅画时，常常将其归类为一种风格。这幅画被视为该风格典型的程度称为其风格原型。作者提出了一种量化风格原型的方法，并使用漂移扩散模型的漂移率参数进行了实验来验证该方法。该参数是使用参与者的决策响应时间计算的。作者发现漂移率与本研究中使用的绘画的量化原型之间存在正相关性（ r = .88，p < .001），证实了所提出的量化方法的心理适当性。
