在单个特征搜索任务中，有几种不同的维度间隔效应和提示效应。一些说法认为这些效应发生在选择后加工阶段；双路径假设它们本质上是感性的，但只在非空间任务中发挥作用（例如，检测而不是定位）。相反，维度加权解释（DWA）假设维度效应出现在空间任务和非空间任务的注意前加工阶段。现有的数据模棱两可，在这些说法中没有明确的选择。因此，本研究检查了空间任务中维度加权的早期影响，其存在仅由DWA预测，而不是由后选择或双路径解释预测。对于高特征对比度和较长的呈现时间，显著性是饱和的。因此，尽管自下而上的显著性较低，但仍然允许高效搜索，维度权重将产生更大的调制（如果存在的话）。因此，我们在实验1中考察了简要呈现条件下的定位精度，在实验2中考察了低和高特征对比度条件下的定位速度。两个实验都显示了显著的维度间效应和提示效应。这有力地反驳了双路径说，并加强了这些效应的预先注意起源的证据。
There are several alternative accounts of dimensional intertrial and cueing effects in singleton feature search tasks. Some accounts assume that these effects arise at post-selective processing stages; dual-route accounts assume them to be perceptual in nature, but coming into play only in non-spatial tasks (e.g., detection but not localization). By contrast, the Dimension Weighting Account (DWA) assumes dimensional effects to arise at pre-attentive processing stages of spatial as well as non-spatial tasks. The data available are ambiguous, permitting no clear-cut choice among these accounts. Therefore, the present study examined for early effects of dimensional weighting in a spatial task, the presence of which is only predicted by the DWA and not by post-selective or dual-route accounts. Salience is known to saturate for high feature contrast and long presentation times. Consequently, with lower bottom-up salience that still permits efficient search, dimensional weights would produce a greater modulation—if present at all. Thus, we examined localization accuracy under brief-presentation conditions in Experiment 1, and localization speed under conditions of low versus high feature contrast in Experiment 2. Both experiments revealed significant dimension intertrial and cueing effects. This strongly argues against dual-route accounts and strengthens evidence for a pre-attentive origin of these effects.
