Abstract

    We administered a task to forty Japanese aphasic patients in which they were to choose the particles to various combination of nouns and verbs, and analyzed the strategies involved in their choices. The task consisted of 233 two-word sentences (noun + particle — verb) in which spaces for the particles were left blank. The subjects were asked to fill in each blank with one from a choice of five particles. The choice of sentences for the task was based on a statistical study of the frequency of use of nouns and noun-particle combinations drawn from a data-base consisting of 494, 956 words of the speech of normal Japanese. The sentences which required the particle “wo” were 76, those which required the particle “kara” were four, those which required the particle “ga” were 67, those which required the particle “de” were 25, and those which required particle “ni” were 30. The remaining sentences allowed more than one particle. Furthermore, in 197 of the sentences the noun phrases represented essential arguments of the verbs, and in 27 the noun phrases represented optional arguments. The subjects were forty chronic aphasic patients of whom fourteen were suffering from Wernicke's aphasia, nine from Broca's aphasia, three mixed, four conduction aphasia, and ten cases of amnestic aphasia.<br>    Results were as follows. The difficulty in choosing the correct particle was influenced by the frequency of conjunction of noun and particle, as well as by the nature of the argument (essential or optional). Further, it was also influenced by the severity of the comprehension disorder.
