Influence of Attention Training on Chinese Character Processing Capability in Poststroke Nonfluent Aphasiacs / 中国康复理论与实践

ABSTRACT

Objective To explore the influence of attention training on Chinese character processing capability in poststroke nonfluent aphasiacs. Methods 60 stroke patients with nonfluent aphasia and cognition dysfunction were divided into control group (n=30) and experi-mental group (n=30). The trainings (attention training and cognition training) were respectively 30 minutes each time, 5 times each week for 4 weeks. The change of reaction time and error rate were compared before and after they were performing the orthographic, semantic and phonological tasks. Results In the dual-task paradigm the change of reaction time and error rate in orthographic and semantic tasks of the ex-perimental group were all higher than the control group (P0.05). In the single task paradigm there was no difference between the two groups (P>0.05). Conclusion 1. Attention training can improve the processing capacity significantly in orthographic and semantic tasks in the dual-task paradigm because the volume and distribu-tive ability of attention improve significantly. 2. Attention training can't improve the processing capacity in phonological tasks in the du-al-task paradigm because reading aloud and judging are required to process the vowel simultaneously. So that the competion intensifies and it is more difficult to finish the task. 3. In the single task paradigm, there is no significant difference between the influence of the two train-ings in poststroke nonfluent aphasiac because the single task needs little attention and the change in the control group is enough.
