目标导向的认知经常被讨论为专门的记忆结构，如“目标堆栈”。“这里提出的目标激活模型从激活和联想启动的一般记忆结构方面分析了目标导向认知。该模型包含三个预测约束：（1）干扰水平，这是由对旧目标的残留记忆引起的;（1）强化约束，这是对编码新目标的时间的预测;（3）启动约束，这是对线索在检索未决目标中的作用的预测。这些约束是制定代数和测试，通过模拟的延迟和错误数据从河内塔，手段-目的的难题，在很大程度上取决于暂停和恢复的目标。理解意图优势、完成后错误模型的意义。和任务中断的影响进行了讨论。(C)2002年认知科学学会All rights reserved.
Goal-directed cognition is often discussed in terms of specialized memory structures like the "goal stack." The goal-activation model presented here analyzes goal-directed cognition in terms of the general memory constructs of activation and associative priming. The model embodies three predictive constraints: (1) the interference level, which arises from residual memory for old goals; (1) the strengthening constraint, which makes predictions about time to encode a new goal: and (3) the priming constraint, which makes predictions about the role of cues in retrieving pending goals. These constraints are formulated algebraically and tested through simulation of latency and error data from the Tower of Hanoi, a means-ends puzzle that depends heavily on suspension and resumption of goals. Implications of the model for understanding intention superiority, postcompletion error. and effects of task interruption are discussed. (C) 2002 Cognitive Science Society, Inc. All rights reserved.
