Two views on the semantics of concrete words are that their core mental representations are feature-based or are reconstructions of sensory experience. We argue that neither of these approaches is capable of representing the semantics of abstract words, which involve the representation of possibly hypothetical physical and mental states, the binding of entities within a structure, and the possible use of embedding (or recursion) in such structures. Brain based evidence in the form of dissociations between deficits related to concrete and abstract semantics corroborates the hypothesis. Neuroimaging evidence suggests that left lateral inferior frontal cortex supports those processes responsible for the representation of abstract words.
关于具体词语义的两种观点认为,它们的核心心理表征是基于特征的,或者是对感官体验的重建。我们认为,这两种方法都不能代表抽象词的语义,因为抽象词涉及可能假设的物理和心理状态的表示、实体在结构内的绑定,以及在这种结构中可能使用嵌入(或递归)。以具体语义和抽象语义相关缺陷之间的分离为形式的基于大脑的证据证实了这一假设。神经影像学证据表明,左侧下外侧额皮质支持那些负责表示抽象词的过程。
