Other AbstractThe neurologists coined the term “constructional apraxia” to describe "a disturbance in formative activities (arranging, building, and drawing)" in which the spatial part of the task is missed. Influenced by the localizationist associationist theoretical trend, the studies of constructional apraxia has generally been descriptive, and followed an anatomo-clinical approach in the past 100 years. However, this framework has not been successful in grasping the componential nature of the processing deficits underlying constructional apraxia.
This study employed traditional neuropsychological tests and cognitive neuropsychological methods to research the characteristics and mechanisms of constructional apraxia caused by brain lesions in traditional two dimension constructional tests and Chinese character writing task. The traditional neuropsychological tests included simple 2D figure copy, Bender gestalt test, Rey complex figure copy, simple 3D figure copy, clock drawing test, house drawing test, stick building test, and Kohs block building test. The character writing test was Chinese character copying test. Ambiguous figure identification task, image mental rotation task, and image mental composite task were used to implore patients’ imaginary abilities. The main results are listed as followes:
1.The constructional apraxia which caused by brain lesions was reflected in all of the two dimension constructional tasks.
2.The degree of figure complexity and the features of the tasks were important factors which determined the success or failure in finishing the tasks.
3.Rey complex figure copy test, simple 3D figure copy and Chinese character copy test were sensitive and proper in evaluating the constructive abilities of brain lesions in China.
4.Constructional apraxia was closely related with impairment of imaginary ability.
5.The efficiencies of constructional apraxia subjects’ in processing spatial information are lower than normal subjects’, patients’ fixation patterns were abnormal, and they were easier to be attracted by irrelevant stimuli.
The present study explored the charecteristics of patients’ constructive cognition with brain-lesions in China, proposed the tests which are suitable for Chinese in clinical, and identified the close relationship between constructional apraxia and disable in imaginary.
