Down syndrome, phonological awareness, writing and working memory.
to evaluate the phonological awareness of Brazilian children with Down syndrome; to analyze the relationship between the writing hypothesis and the phonological awareness scores of the participants; to compare the performance of children with Down syndrome to that of children with typical development according to the Phonological Awareness: Tool for sequential evaluation (PHONATSE), using the writing hypothesis as a matching criteria; to verify the correlation between the phonological awareness measurements and the phonological working memory.
a group of eleven children aged between 7 and 14 years (average: 9 y 10 m) was selected for the study. Phonological awareness was evaluated using the PHONATSE. The phonological working memory was evaluated through an instrument developed by the researcher.
all subjects presented measurable levels of phonological awareness through the PHONATSE. The phonological awareness scores and the writing hypothesis presented a significant positive association. The performance of children with Down syndrome was significantly lower than children with typical development who presented the same writing hypothesis. Measurements of phonological awareness and phonological working memory presented significant positive correlations.
the phonological awareness of Brazilian children with Down syndrome can be evaluated through the PHONATSE. Syllable awareness improves with literacy, whereas phonemic awareness seems to result from written language learning. The phonological working memory influences the performance of children with Down syndrome in phonological awareness tasks.
唐氏综合征、语音意识、书写与工作记忆。
评估巴西唐氏综合征儿童的语音意识;分析书写假设与参与者语音意识得分之间的关系;根据语音意识:顺序评估工具(PHONATSE),以书写假设作为匹配标准,比较唐氏综合征儿童与发育正常儿童的表现;验证语音意识测量与语音工作记忆之间的相关性。
选取一组11名年龄在7至14岁之间(平均:9岁10个月)的儿童进行研究。使用PHONATSE评估语音意识。通过研究人员开发的工具评估语音工作记忆。
所有受试者通过PHONATSE均呈现出可测量的语音意识水平。语音意识得分与书写假设呈现出显著的正相关。唐氏综合征儿童的表现显著低于具有相同书写假设但发育正常的儿童。语音意识测量与语音工作记忆呈现出显著的正相关。
巴西唐氏综合征儿童的语音意识可通过PHONATSE进行评估。音节意识随着读写能力的提高而改善,而音素意识似乎源于书面语言学习。语音工作记忆影响唐氏综合征儿童在语音意识任务中的表现。
