Research based on the Category Adjustment model concluded that the spatial distribution of target locations does not influence location estimation responses [Huttenlocher, J., Hedges, L., Corrigan, B., & Crawford, L. E. (2004). Spatial categories and the estimation of location. Cognition, 93, 75-97]. This conflicts with earlier results showing that location estimation is biased relative to the spatial distribution of targets [Spencer, J. P., & Hund, A. M. (2002). Prototypes and particulars: Geometric and experience-dependent spatial categories. Journal of Experimental Psychology: General, 131, 16-37]. Here, we resolve this controversy by using a task based on Huttenlocher et al. (Experiment 4) with minor modifications to enhance our ability to detect experience-dependent effects. Results after the first block of trials replicate the pattern reported in Huttenlocher et al. After additional experience, however, participants showed biases that significantly shifted according to the target distributions. These results are consistent with the Dynamic Field Theory, an alternative theory of spatial cognition that integrates long-term memory traces across trials relative to the perceived structure of the task space.
基于类别调整模型的研究得出结论，目标位置的空间分布不会影响位置估计反应[Huttenlocher，J.，Hedges，L.，Corrigan，B.，& Crawford，L. E.（2004）。空间类别和位置估计。认知，93，75-97]。这与早期的结果相矛盾，早期的结果表明位置估计相对于目标的空间分布存在偏差[Spencer，J. P.，& Hund，A. M.（2002）。原型和细节：基于几何和经验的空间类别。实验心理学杂志：一般，131，16-37]。在这里，我们通过使用基于 Huttenlocher 等人的任务（实验 4）并进行一些修改来解决这一争议，这些修改增强了我们检测经验相关效应的能力。在第一轮试验后得到的结果复制了 Huttenlocher 等人报告的模式。然而，在额外的经验之后，参与者表现出了明显根据目标分布而变化的偏差。这些结果与动态场理论一致，这是一种空间认知的替代理论，它整合了跨试验的长期记忆痕迹，相对于任务空间的感知结构。
