Neurocognitive plasticity and development of communication bases

本研究调查了早期和后期生活中不同类型的经历如何影响人类的沟通基础。结果如下：母语类型（日语和英语）影响语音感知的视听整合，这一点可以从婴儿的凝视行为、成人的大脑反应（ERP、fMRI）和行为（RT和凝视）中得到证明。在人工耳蜗使用者的语音感知中，表现良好者的脑反应（ERP）显示出与正常听力相似的成分，表明与表现较差者相比，人工耳蜗使用者在噪声环境下的语音感知开始恢复。关于移情的神经基础，fMRI显示了一种自己母亲特有的识别面部表情的激活。一项针对高社交焦虑学生的认知行为治疗方案在脑反应（NIRS）方面显示了干预效果。

This study investigated how different types of experiences in early and later in life affect human communication bases. The results are as follows. The type of native language (Japanese versus English) affects auditory-visual integration in speech perception, as evidenced by gaze behavior in infancy, adult brain responses (ERP, fMRI) and behavior (RT and gaze). In cochlear implant user's speech perception, good performers' brain responses (ERP) showed a component similar to that of normal hearing, indicating the beginning of restoration of speech perception in noise, as compared with poor performers. Concerning neural bases of empathy, fMRI revealed an own-mother-specific activation for recognizing facial expressions. A cognitive behavioral therapy program for students with high social anxiety indicated an intervention effect in brain responses (NIRS).
