Speech Category Learning: Models, Methods and Researches
-
摘要: 语音类别学习是人类重要的认知机制之一,其能降低认知负荷、加快学习速度,以使人更好适应环境。双系统模型是当前语音类别学习的主要理论模型,它假设语音类别学习存在着相互竞争的两个系统,即外显学习系统和内隐学习系统;语音类别学习的研究主要针对人工语音材料和自然性的普通话材料,采用延迟反馈和及时反馈、丰富反馈和简单反馈、组合式发音和随机混合式发音等方式来探讨语音类别学习外显和内隐系统的特点。已有研究主要探究语音类别学习中工作记忆的作用,普通话分类习得和不同人群的语音类别学习特点,未来研究应注意谨慎借鉴知觉类别学习的研究成果,并可在认知研究、老年人视听问题等方面进一步加强。Abstract: Speech category learning is one of the most important cognitive mechanisms in human beings. At present, the main theoretical model of speech category learning is the dual system model, which includes explicit hypothesis testing reflective system and implicit procedure based reflexive system. Researches in speech category learning mainly aim at the artificial auditory stimuli and natural Mandarin Chinese. They should dissociate the reflective system and reflexive system to verify the existence of dual system model. In the current study, delayed feedback and immediate feedback, full feedback and minimal feedback, blocked talkers and mixed talkers are all used to explore the characteristic of reflective system, so do reflexive system. Despite the achievements in speech category learning, it is important to note that the research findings in perceptual category learning should be initroduced in speech category learning carefully in the future research. The cognitive mechanism and learning ability of the elderly, children, bilinguals can also be further studied.
