Broca’s aphasia

(redirected from agrammatic aphasia)

Broca’s aphasia

Loss of language ability due to damage in Broca's area (Brodmann area 44 and 45), characterised by telegraphic speech in which the meaning is usually clear but the grammatical connecting words are missing, with retained comprehension.

Aetiology
Stroke, usually due to thromboembolism; less commonly due to brain tumours, cerebral haemorrhage, extradural haematoma.

This paper tests some of these predictions for certain distributions in three types of data: code switching, agrammatic aphasia, and interlanguage in second-language acquisition.
Two predictions follow from the 4-M model: (1) some functional elements or closed-class items will occur in agrammatic aphasia simply because they are content morphemes under the 4-M model, such as personal pronouns in English; (2) the division of [+/- conceptually activated] in the 4-M model will mean that early system morphemes should pattern more like content morphemes and, therefore, be more accurate than either of the other two classes of system morphemes.

A telling observation regarding agrammatic aphasia mitigates against this and suggests that another explanation is needed: such categories as main verbs (they assign thematic roles) and adjectives (they can assign thematic roles or be part of a larger NP that receives a thematic role) are more accurately produced by aphasics than any other category (cf.
They are of even more interest to researchers studying language production and processing because they indicate that agrammatic aphasia is more of a production problem than a more general problem of lexical access.
