On the understanding of some relational words in aphasia.

Abstract After determining whether 5 aphasic men spoke prepositions spontaneously, this study proceeded in 2 parts. First, we required the subjects to make arrangements of objects following directions spoken by the experimenter. Secondly, we required the subjects to order pre-printed word-cards into statements describing various displays of objects. We concluded from our data that (1) aphasics understood relational terms (e.g. prepositions) less well than object names, but (2) they were able to order words systematically, as parts of speech, into statements following or closely approximating the conventional rules of English.
