A comparison of aphasic and normal adults in a sentence-verification task.
This study showed that in certain sentence-processing tasks, aphasics fail to perform correctly because they fail to execute particular mental operations. A straightforward information-processing model describes the mental processes that are used in deciding whether a sentence is true or false of an accompanying picture. The aphasics' performance, interpreted in light of the model, indicates what step in their processing is not operating properly in this task.
