ABSTRACT
This article investigated the role of semantic transparency in processing root compound nouns in Persian individuals with Broca's aphasia through picture confrontation naming and repetition tasks. The relationship between semantic transparency and affected constituents of nouns showed that semantic transparency had no role in processing compound nouns. The results showed that transparent, opaque and partially transparent compound nouns were processed by dual-routes (holistic and decomposing). Frequency of errors also revealed dissociation of naming and repetition processes as well as simple and compound nouns. The comparison of errors and their types in confrontation naming and repetition tasks indicated that naming was relatively more complex than repetition.
