| 中文摘要 | 本研究以小学三年级、五年级和初中一年级汉语儿童为研究对象，探查了在语音加工过程声旁家族效应的行为、神经机制的表现和发展过程。结果表明汉字家族效应在儿童阅读早期就已经存在，但是表现并不一致。行为结果表现为大家族促进三、五年级儿童的命名过程，而抑制初一年级儿童的语音提取，并且这些结果也相应的体现于神经活动之中。对于三年级、五年级儿童而言，小家族比大家族在左侧额中回引起了更强的激活，说明大家族目标字的语音整合更为容易。而初一儿童的大家族比小家族在左侧额下回有更强的激活，说明高频成员字的语音干扰作用的存在。初一年级儿童的家族效应接近成人水平，但未完全成熟。 |
| 英文摘要 | The third grade, fifth grade and junior high school Chinese children participated in present study concerning the neighborhood size effect in Chinese reading processing. With the aim of exploration of the cognitive and neural mechanisms underlying this effect during development, naming task and fMRI experiment were conducted. The results from behavior and neural activity shown that neighborhood size effect already existed in children with early reading experience. Large neighborhood facilitated phonological retrieval for the third and fifth grade children, inhibited naming for high school children. Brain activations relative to the neighborhood size effect revealing that left middle frontal gyrus was significantly activated more for small neighborhood compared to large one for grade 3 and 5 children, suggesting the facilitation of large neighborhood. In addit ion, imaging results identified greater activation in left inferior frontal gyrus for large than small neighborhood indicating interference of higher-frequency neighbors regarding junior high school, this result suggested that the effect of neighborhood close to that of adult, but were still not fully mature. |
