大多数加工阶段理论家认为，反应选择过程在很大程度上是自主的，不受早期对信息的知觉分析的影响。我们报告的结果，挑战这一假设，并建议，一个更复杂的相互作用之间存在的感知和行动。具体来说，我们的研究表明，从不同的维度的功能的视觉对象的初步分析强烈约束反应选择的后知觉过程。当与基于一个维度的应答相关的靶标与基于另一个维度的应答相关的侧翼同时呈递时，对靶标的应答不受侧翼身份的影响。这些发现在各种条件下都成立，似乎是特定于感知维度的。当目标和侧翼都与基于相同维度的响应相关联时，即使目标和侧翼在感知上不相似或属于不同的语义类别（数字和字母），对目标的响应也会受到侧翼身份的影响。我们提出了一个模型的响应选择，可以解释这些发现。该模型假设，简单的功能的初始响应选择过程中进行的维度模块，并建议一个特定的中介作用的空间注意。我们认为，这个模型是兼容的其他几个班轮的研究。(C)北京：科学出版社.
Most processing stages theorists assume that response selection processes are largely autonomous from earlier perceptual analysis of information. We report findings that challenge this assumption and suggest that a much more complex interaction exists between perception and action. Specifically our study demonstrates that the initial analysis of visual objects into features from different dimensions strongly constrains postperceptual processes of response selection. When a target that is associated with a response on the basis of one dimension is presented simultaneously with flankers that are associated with a response on the basis of another dimension, the response to the target is not affected by the identity of the flankers. These findings hold under a variety of conditions and appear to be specific to perceptual dimensions. When both target and flankers are associated with a response on the basis of the same dimension, the response to the target is affected by the identity of the flankers even when the target and flankers are perceptually dissimilar or belong to different semantic categories (digits and letters). We propose a model of response selection that can account for these findings. The model assumes that initial response selection processes for simple features are performed within dimensional modules and suggests a specific mediating role for spatial attention. We argue that this model is compatible with several other liner of research. (C) 1997 Academic Press.
