Traditionally, agrammatism was viewed as a restricted disorder of speech production which was associated with Broca's aphasia. This view has been replaced by a more complex picture which involves a range of linguistic impairments in both language production and comprehension. These disorders have been variously characterized as deficits, in the representation of linguistic structures and deficits in the on-line computation of sentence structures and their interpretations. A variety of analyses of production and comprehension in agrammatism, invoking both representational and computational analyses, are reviewed. Each has inadequacies, but, at the same time, it is argued that each also advances the understanding of agrammatism.
传统上，语法缺失被视为一种与布罗卡失语症相关的言语产生受限障碍。这一观点已被一幅更为复杂的图景所取代，该图景涉及语言产生和理解方面的一系列语言障碍。这些障碍被不同地描述为语言结构表征方面的缺陷以及句子结构及其解释的在线计算方面的缺陷。本文回顾了对语法缺失中产生和理解的各种分析，这些分析同时运用了表征分析和计算分析。每种分析都有不足之处，但同时也有人认为，每种分析都推进了对语法缺失的理解。
