This article introduces the P-chain, an emerging framework for theory in psycholinguistics that unifies research on comprehension, production and acquisition. The framework proposes that language processing involves incremental prediction, which is carried out by the production system. Prediction necessarily leads to prediction error, which drives learning, including both adaptive adjustment to the mature language processing system as well as language acquisition. To illustrate the P-chain, we review the Dual-path model of sentence production, a connectionist model that explains structural priming in production and a number of facts about language acquisition. The potential of this and related models for explaining acquired and developmental disorders of sentence production is discussed.
本文介绍了 P 链，这是心理语言学理论中的一个新兴框架，它将理解、生成和习得的研究统一起来。该框架提出，语言处理涉及到逐步预测，这是由生成系统来执行的。预测必然会导致预测错误，从而推动学习，包括对成熟的语言处理系统的适应性调整以及语言习得。为了说明 P 链，我们回顾了句子生成的双路径模型，这是一个连接主义模型，它解释了生成中的结构启动，并解释了语言习得的许多事实。讨论了这种模型和相关模型在解释句子生成的获得性和发育障碍方面的潜力。
