The authors examined whether 2 computational models of reading, the dual-route cascaded model (M. Coltheart, K. Rastle, C. Perry, R. Langdon, & J. C. Ziegler, 2001) and the connectionist 2-layer model (M. Zorzi, G. Houghton, & B. Butterworth, 1998), were able to predict the pattern that the length effect found in reading aloud is larger in German than in English (J. C. Ziegler, C. Perry, A. M. Jacobs, & M. Braun, 2001). The results showed that the dual-route cascaded model, which uses a serial mechanism for assembling phonology, successfully predicted this cross-language difference. In contrast, the connectionist model of Zorzi et al. (1998) predicted the opposite: a larger length effect in English than in German. Both the success of one model and the failure of the other highlight fundamental differences between 2 major classes of computational models.
作者们研究了两种阅读计算模型，即双通道级联模型（M. 科尔特哈特、K. 拉斯特尔、C. 佩里、R. 兰登和J. C. 齐格勒，2001年）和联结主义双层模型（M. 佐尔齐、G. 霍顿和B. 巴特沃思，1998年），是否能够预测在朗读中发现的长度效应在德语中比在英语中更大这一模式（J. C. 齐格勒、C. 佩里、A. M. 雅各布斯和M. 布劳恩，2001年）。结果表明，使用串行机制来组装语音的双通道级联模型成功地预测了这种跨语言差异。相比之下，佐尔齐等人（1998年）的联结主义模型预测的结果则相反：英语中的长度效应比德语中更大。一个模型的成功和另一个模型的失败都凸显了两类主要计算模型之间的根本差异。
