ABSTRACT
This conclusion presents some closing thoughts on key concepts discussed in the preceding chapters of this book. The book explains the historical economy of effort hypothesis. Both the economy of effort hypothesis and Adaptation Theory has maintained that the agrammatic symptom complex in relation to speech production does not reflect impairment, but is a response to it. It outlines the costliness of scope-discourse features and their vulnerability in agrammatic Broca's aphasia is assumed, it has much independent backing. The book also explains empirical work on the interpretation of pronominals in different contexts with agrammatic Broca's aphasic patients. It talks about five decades of intense research activity that has focused on the language impairments of agrammatic Broca's aphasic patients. The book explores utterances produced by different populations that do not conform to normal grammar, outlines the rules nonsententials follow, and rejects the suggestion that they are derived from grammatical sentences by a series of deletions.
