采取图画-词汇干扰实验范式,探索汉语词汇产生中词条选择和音韵编码两个阶段之间是否存在激活的反馈。实验一探索的是字形激活能否反馈至语义层产生语义激活,结果发现,与无关条件相比,目标图画(如“锯”)的字形中介(“镇”)的语义相关字(“村”)条件显著地延长了图画命名的时间。这表明在汉语词汇产生过程中,字形层的激活能反馈至语义层。实验二探索的是语音激活能否反馈至语义层产生语义激活,结果发现,与无关条件相比,目标图画(“梨”)的语音中介(“厘”)的语义相关字(“毫”)条件并未显著地影响图画命名的时间。这表明语音层的激活不能反馈至语义层,或者反馈回的激活太微弱不能影响图画命名过程。实验一和二的结果更倾向于支持词汇产生中词条选择和音韵编码两个阶段独立的观点。 相似文献

Socioeconomic status (SES) has been shown to influence language skills, with children of lower SES backgrounds performing worse on language assessments compared to their higher SES peers. While there is abundant behavioral research on the effects of SES, whether there are differences in the neural mechanisms used to support language skill is less established. In this study, we examined the relation between maternal education (ME), a component of SES, and neural mechanisms of language. We focused on Kindergarten children, at the beginning of formal reading education, and on a pre‐reading skill, phonological awareness—the ability to distinguish or manipulate the sounds of language. We determined ME‐related differences in neural activity by examining a skill‐matched sample of typically achieving 5‐year‐old children as they performed a rhyme judgment task. We examined brain lateralization in two language processing regions, the inferior frontal gyrus (IFG) and superior temporal gyrus (STG). In the IFG, lateralization was related to ME but not skill: children with low ME showed bilateral activation compared to children with higher ME who showed leftward lateralization. In the STG, there was a skill by ME interaction on lateralization, such that children with high ME showed a positive relation between rightward lateralization and skill and children with low ME showed a positive relation between leftward lateralization and skill. Thus, we demonstrated ME is related to differences in neural recruitment during language processing, yet this difference in recruitment is not indicative of a deficit in linguistic processing in Kindergarten children. 相似文献

言语产生的语音加工单元具有跨语言的特异性。在印欧语言中, 音位是语音加工的重要功能单元。音位指具体语言中能够区别意义的最小语音单位, 如“big”包含三个音位/b/, /i/, /g/。目前, 在汉语言语产生中, 对音位的研究较少。本项目拟采用事件相关电位技术, 对汉语言语产生中的音位加工进行探讨, 试图考察:在汉语言语产生中, 1)音位加工的心理现实性, 以及音位表征是否受第二语言、汉语拼音习得、拼音使用经验的影响?2)音位的加工机制是怎样的?具体而言, 音位加工的特异性、位置编码、组合方式、时间进程是怎样的?对这些问题的回答, 将有助于深化对汉语言语产生的认识, 为建立汉语言语产生计算模型提供基础; 为比较印欧语言与汉语在机制上的异同提供基础; 为制定汉语语音教育教学方法提供心理学依据。 相似文献

中国香港双语儿童初步阅读能力与语音、文字加工关系的研究 总被引:5,自引:1,他引:4
采用音节检测、短时言语记忆、快速命名等语音加工任务和汉字、字母、数字等方向加工任务,探讨语音和文字加工在儿童初步阅读中的作用,116名6岁左右的香港双语儿童参加了测试。结果表明:语音加工能力是跨语言的比较稳定的因素,是预测汉语和英语阅读的较好指标;文字加工具有特异性.即汉字方向加工只能预测汉语阅读,字母方向加工则预测英语阅读。 相似文献

Phoneme awareness is a better predictor of early reading skill than onset-rime awareness 总被引:10,自引:0,他引:10
Hulme C Hatcher PJ Nation K Brown A Adams J Stuart G 《Journal of experimental child psychology》2002,82(1):2-28
We present the results of a short-term longitudinal study. Children in the early stages of learning to read (5 and 6 year olds) were administered three different tasks (deletion, oddity, and detection) tapping awareness of four phonological units (initial phoneme, final phoneme, onset, and rime). Measures of phoneme awareness were the best concurrent and longitudinal predictors of reading skill with onset-rime skills making no additional predictive contribution once phonemic skills were accounted for. The findings are related to recent controversy over the role of large versus small phonological units as predictors of children's reading skills. 相似文献
