Objective: The goal of the present study is to assess the question of whether linguistic capabilities in the mind, are independent and distinguishable from other cognitive capabilities, or are there relationships between linguistic capabilities and non-linguistic cognitive capabilities.
Methods: To this end, we measured the relationship between the capability of syntactic comprehension and the capability of processing cognitive sequences in Broca aphasia patients. This was a comparative-descriptive study. Ten Broca aphasia patients were selected via goal-directed approach from public speech-therapy centers in the city of Tehran. Caplan et al.’s test for syntactic comprehension and Lelekov’s process of cognitive sequences were administered to the subjects and the results of the two tests were compared.
Results: Findings indicated a direct relationship between the comprehension of some syntactic structures and the ability of processing cognitive sequences (r=o.5). The inability of Broca patients to correctly affiliate semantic roles, is related to a more general cognitive disorder due to impairment in neural structures, common between the process of linguistic comprehension and cognitive sequences.
Conclusion: contrary to the modularity theory of language, linguistic capabilities of humans could not be limited to an independent faculty in the mind; and it should be accepted that linguistic capabilities and non-linguistic cognitive capabilities interact with each other.
