초록
The present study aims at investigating the effect of Korean word frequency and phonological change in language disorder. Several types of aphasics showing Broca's aphasia, anomia, and verbal apraxia participated in this experiment. In experiment 1, we used the naming task related to word reading. Differently from the presence of the frequency effect in normal controls, the effect in word reading task showed different pattern across the aphasics. Moreover the phonological effect appeared to be inconsistent over the patients. Experiment 2 using lexical decision task also examined the effects just mentioned in Experiment 1 together with the effects according to types of nonwords. The first result in using word stimuli showed the dissociation between the effects of frequency and phonological change in aphasics in contrast to the normal subjects showing the phonological effect only in case of low frequency word. The second result of lexical decision time applied in pure-nonword and homonymous-nonword according to the presence or absence of phonological change showed different patterns across the aphasic patients. These results suggest that the strategies for the lexical decision in aphasics revealed the biasedness of lexical-addressed route irrespective of frequency and phonological change factors, whereas phonological-assembled route can be used for the nonwords as did in normal controls.
Abstract
The present study aims at investigating the effect of Korean word frequency and phonological change in language disorder. Several types of aphasics showing Broca's aphasia, anomia, and verbal apraxia participated in this experiment. In experiment 1, we used the naming task related to word reading. Differently from the presence of the frequency effect in normal controls, the effect in word reading task showed different pattern across the aphasics. Moreover the phonological effect appeared to be inconsistent over the patients. Experiment 2 using lexical decision task also examined the effects just mentioned in Experiment 1 together with the effects according to types of nonwords. The first result in using word stimuli showed the dissociation between the effects of frequency and phonological change in aphasics in contrast to the normal subjects showing the phonological effect only in case of low frequency word.
