Outline of Final Research Achievements

This study investigated the characteristics of the processing strategies of visual non-verbal cognitive tasks in deaf people, in terms of cognitive tasks (gazing tasks, perceptual tasks, spatial memory tasks, problem-solving tasks and visual materials) and individual linguistic differences (language skills and language modes) of deaf people. Overall, the results of the study showed that deaf people can process visual non-verbal tasks more efficiently than hearing people, and that although performance on various cognitive tasks did not show the influence of language ability or language mode, the processing strategy of the tasks generally differed according to language mode. However, it was suggested that differences in language ability may be indicated in visual non-verbal cognition, which is more difficult and easier to process verbally. It was also suggested that visual materials utilised in deaf education settings may have an effective impact on ease of comprehension and learning.

Academic Significance and Societal Importance of the Research Achievements

聴覚障害者と健聴者との間にみられる認知機能の相違は、周辺とのコミュニケーションがうまくとれない環境とその中で培われた経験の違いがもたらす相違であると考えられている。しかしながら、これまでの研究対象の聴覚障害者の言語モードについて明確な規定がなく、言語力との関連性も明らかではない。聴覚障害者の認知機能については、課題の特性や言語力に基づく聴覚障害者の視覚的非言語性認知課題の活用に関しては明確な知見が得られていない。本研究を通して、聴覚障害者の認知処理方略の特徴が究明できれば、その知見を背景に、聴覚障害教育現場における認知課題の解決について大きな成果をもたらすことが期待できる。
