五个实验报告，从它的结论是，参加刺激功能（如红色）的基础上，不直接影响感官质量的刺激，拥有该功能。在视觉搜索任务中，通过提供关于目标将拥有给定特征的概率的信息（例如，”目标在出现时有1.0的概率是红色的。").在”数据有限”条件下（即，表现主要受刺激质量影响的条件下），基于记忆的注意力未能帮助表现，但在非数据有限的条件下确实影响表现（实验1-3）。如果关注一个特征影响了刺激的感官质量，那么在所有条件下都应该帮助表现。实验4和5为这一结论提供了一致的支持。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Five experiments are reported from which it is concluded that attending on the basis of a stimulus feature (eg, red) does not directly affect the sensory quality of stimuli that possess that feature. Feature-based attention was manipulated in a visual search task by providing information about the probability that the target would possess a given feature (eg," The target has a 1.0 probability of being red when present."). Feature-based attention failed to aid performance under" data-limited" conditions (ie, those under which performance was primarily affected by the quality of the stimulus) but did affect performance under conditions that were not data limited (Experiments 1–3). If attending to a feature had affected the sensory quality of stimuli, performance should have been aided under all conditions. Experiments 4 and 5 provided converging support for this conclusion.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
