초록
Eight cases of progressive supranuclear palsy (PSP) and eight normal subjects as control group were studied to examine whether their naming ability was affected or not. The naming ability that was examined was “action and object naming” of the patients with the help of a “picture naming test”, designed for Hindi speaking population. The paper aims to examine if there is any action and object naming deficits in Hindi speaking patients suffering from PSP. The study also analyzes the degree of impairment in the patients suffering from PSP. PSP patients exhibit “slurred speech” but is the impairment only “phonological” or the lexicon is also impaired? Finally the study aims to assess the degree of impairment manifested through PSP in nouns and verbs in PSP patients. PSP is caused due to damage to the frontal lobe which has been proven to be involved in controlling body movements. Earlier researches have established the fact that the damage to the frontal lobe always leads to the impairment of verbs (Cappa and Perani 2003; Cotelli 2006). However the current study also points out the noun impairment in PSP patients. This study is an attempt to understand the mental lexicon concentrating on the organization of nouns and verbs in the mental lexicon.
Abstract
Eight cases of progressive supranuclear palsy (PSP) and eight normal subjects as control group were studied to examine whether their naming ability was affected or not. The naming ability that was examined was “action and object naming” of the patients with the help of a “picture naming test”, designed for Hindi speaking population. The paper aims to examine if there is any action and object naming deficits in Hindi speaking patients suffering from PSP. The study also analyzes the degree of impairment in the patients suffering from PSP. PSP patients exhibit “slurred speech” but is the impairment only “phonological” or the lexicon is also impaired? Finally the study aims to assess the degree of impairment manifested through PSP in nouns and verbs in PSP patients. PSP is caused due to damage to the frontal lobe which has been proven to be involved in controlling body movements. Earlier researches have established the fact that the damage to the frontal lobe always leads to the impairment of verbs (Cappa and Perani 2003; Cotelli 2006). However the current study also points out the noun impairment in PSP patients. This study is an attempt to understand the mental lexicon concentrating on the organization of nouns and verbs in the mental lexicon.
