Two experiments are reported in which linear separability was investigated in superordinate natural language concept pairs (e.g., toiletry-sewing gear). Representations of the exemplars of semantically related concept pairs were derived in two to five dimensions using multidimensional scaling (MDS) of similarities based on possession of the concept features. Next, category membership, obtained from an exemplar generation study (in Experiment 1) and from a forced-choice classification task (in Experiment 2) was predicted from the coordinates of the MDS representation using log linear analysis. The results showed that all natural kind concept pairs were perfectly linearly separable, whereas artifact concept pairs showed several violations. Clear linear separability of natural language concept pairs is in line with independent cue models. The violations in the artifact pairs, however, yield clear evidence against the independent cue models.
本文报告了两项实验，其中对上级自然语言概念对（例如，化妆品-缝纫用具）中的线性可分性进行了研究。基于概念特征的拥有情况，使用相似性的多维缩放（MDS）在两到五个维度上推导语义相关概念对的示例表示。接下来，使用对数线性分析从MDS表示的坐标预测类别成员资格，该资格在实验1中通过示例生成研究获得，在实验2中通过强制选择分类任务获得。结果表明，所有自然类概念对都是完全线性可分的，而人工制品概念对则存在一些违反情况。自然语言概念对的清晰线性可分性与独立线索模型一致。然而，人工制品对中的违反情况提供了明确的证据，反对独立线索模型。
