已有研究发现,用自然语言短句描述物体功能会影响人们对两可物体的分类.本研究请96名大学生阅读多个经过设计、筛选的两可物体,用自然语言呈现其＂正常功能＂和＂异常功能＂,以此恒定并且排除掉自然语言中必然出现的句法成分,保留语义成分,以此考察语义成分对物体命名的特异效应.实验结果表明,人们在正常功能条件下将两可物体分类为人造物的比率显著高于在异常功能条件下将两可物体分类为人造物的比率,而且物体功能的合理程度评分越高,被分类为人造物的可能性就越大.研究提示,人们对物体功能的理解在人造物分类过程中起关键作用,研究结果支持基于用途的人造物分类模型.

英文摘要：

Artifacts（e.g., chair, desk, books） are closely related with peoples＇ daily life. Evidences have been accumulated from behavior experiment, brain damage patient, and neural functional imaging to show that the cognitive neural processing mechanisms are different for artifacts and natural kinds. The intention-based model assumes that people categorize an objects＇ by reasoning the creator＇s intent. Evidence for this model are about ＂intended function＂ effect in categorization, naming, and reasoning studies. However, the utility-based model assumes that using-goal is determining how people categorize an object. The interaction between people and objects make object＇s properties related the using-goal so that the semantic organization of an artifact concept is coherent. This model can explain evidence from study on both intended function and non-intended function. From a third-party perspective, the commonalty of these two models is that they are both purpose-based and the key difference between them is that the creator＇s versus the user＇s purpose influences artifact concept＇s categorization and reasoning. Previous studies used a natural language depiction-based free naming task but seldom separate syntactic component from the semantic component in these depictions. In this study, we recruited 96 participants and manipulated the plausibility of 6 objects＇ function by creating plausible and implausible versions of function depiction to explore how the plausibility of an object＇s function affects participants＇ categorization judgment. The study had two key findings： The plausibility of an object＇s function affects participants＇ naming, rating, and reasoning of an artifact. Participants categorize ambiguous depictions of objects as artifacts when objects＇ function is plausible and categorize them as natural kinds when their function is implausible. The correlation analysis showed that the more plausible an object＇s function is the higher possibility that participants categorize it as
