摘要
词频效应指语言产生中人们对高频词汇的加工比低频词汇更快更准确的一种现象,它可能发生在语言产生中的不同阶段。对青年人和老年人词频效应的不同特点和加工机制进行比较,可以考察语言产生的认知老化机制。通过语言产生理论可对词频效应的老化进行预测,提出词频效应在个体发展和老化阶段的相对稳定性,分析老化导致词频效应相关的神经基础和加工时间进程的改变。未来研究可进一步分离词频效应与习得年龄效应对语言产生老化的影响,并扩展至神经退行性疾病患者中。
The word frequency effect refers to the phenomenon of processing high-frequency words faster and more accurately than processing low-frequency words in different stages of language production.The cognitive ageing mechanisms of language production can be investigated by exploring the different characteristics and mechanisms of the word frequency effect between young people and elderly people.We suggested that the word frequency effect exhibited relative stability across the individual developing stages,predicted the age-related word frequency effect based on different theories of visual word recognition,and analysed the changes in neural substrates and time course of the word frequency effect caused by ageing.In future,we can further distinguish the word frequency effect from the age of acquisition effect on language production,and extend the studies to patients with neurodegenerative diseases.
