Different studies on normal children and children with a sensory or intellectual disability indicate a strong correlation between the child's vocabulary domain and his cognitive abilities. Based on this, the main focus of the present study was to investigate the cognitive performance of cochlear-implanted children after a cognition-based language intervention program.
In this experimental study, 60 cochlear-implanted children were selected and randomly allocated into case and control groups. The control group received auditory verbal therapy (AVT), while the intervention group was trained by using both AVT and a language intervention protocol that was recently developed by the authors. Finally, the participants' communication abilities were assessed through the adapted version of the language subtest of Bayley Scales of Infant and Toddler Development - Third Edition (BSID 3). Five months later, the cognitive subtest was carried out. The data gathered were then analyzed using SPSS software.
The study was performed on 2 groups of 20- to 24-month-old cochlear implant users, and our results confirmed a high correlation between language acquisition and cognitive development (r = 0.76). In addition, the cognitive and language performance of the participants who were trained by the new and specifically designed language intervention protocol as well as AVT was significantly higher than that of the control group (P ≤ .001).
The new and specifically designed language intervention protocol that was mainly established based on cognitive factors such as attention and semantic memory enhancement in cochlear-implanted children improved not only their language acquisition but also their cognitive development.
不同研究表明，正常儿童和感官或智力障碍儿童的词汇量与其认知能力密切相关。基于此，本研究主要关注基于认知的语言干预方案对植入人工耳蜗儿童认知表现的影响。
在这项实验研究中，我们选取了 60 名植入人工耳蜗的儿童，并将他们随机分为病例组和对照组。对照组接受听觉言语治疗（AVT），而干预组则接受 AVT 与我们最近开发的语言干预方案相结合的训练。最后，通过贝利婴幼儿发育量表第三版（BSID 3）语言分量表的改编版本评估参与者的沟通能力。五个月后，进行认知分量表的测试。收集的数据使用 SPSS 软件进行分析。
该研究在 2 组 20 至 24 个月大的人工耳蜗使用者中进行，我们的结果证实了语言习得与认知发展之间的高度相关性（r = 0.76）。此外，接受新的、专门设计的语言干预方案以及 AVT 训练的参与者的认知和语言表现明显高于对照组（P ≤.001）。
新的、专门设计的语言干预方案主要基于认知因素，如注意力和语义记忆增强，不仅提高了植入人工耳蜗儿童的语言习得能力，还促进了他们的认知发展。
