The Effects of Age of Acquisition and Cumulative Frequency on the Recognition of Visual Characters in Children
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.
