摘要
考察五年级小学生在三项汉字识别任务中识别习得早-高频字、习得早-低频字、习得中-低频字和习得晚-低频字的习得年龄效应与累计频率效应.结果发现:(1)语音范畴判断任务和汉字命名任务存在习得年龄效应,ln(习得时长)能预测这两项任务的反应时;(2)语义范畴判断任务和汉字命名任务存在累计频率效应,ln(频率值)能预测这两项任务的反应时.研究结果支持语音完整性假设和网络可塑性假设,不支持累计频率假设和语义假设.
Abstract
To investigate the role of age of acquisition(AoA)and cumulative frequency in children's visual character recognition,four types of characters(early AoA-high frequency,early AoA-low frequency,medium AoA-low frequency,and late AoA-low frequency)were designed,and three types of tasks were conducted in the present study to explore the effects of AoA and cumulative frequency.The results showed that the cumulative frequency effects were present in both the semantic classification task and the immediate naming task,and the AoA effects were present in both the phonetic classification task and the immediate naming task.The regression analysis confirmed that the log-transformed reaction time of recognizing characters in the semantic classification task and the immediate naming task were both predicted by the ln(cumulative frequency),while the reaction time of recognizing characters in the phonetic classification task and the immediate naming task were both predicted by the ln(time known).The above results consistently indicate that the phonological completeness hypothesis and the network plasticity hypothesis,but not the semantic hypothesis and the cumulative frequency hypothesis,can account for AoA and cumulative frequency effects in children's visual character recognition.
