我们对眼前世界的描述在多大程度上仅仅取决于它与我们当前正在做的事情的相关性？我们研究了相关性本身是否会导致“盲目性”，即使没有资源限制。在一种新颖的范例中，人们看着一个被不同颜色的环包围的彩色圆圈，该环的任务相关性先前被操纵 - 随后要求土地识别这些颜色。尽管对与任务相关的颜色的了解近乎完美，但多达四分之一的参与者无法说出不相关刺激的颜色，即使对照实验表明有足够的资源来处理这两种刺激。结果首次证明了当心理资源明显可用时的盲目性，并挑战了注意力理论，该理论预测只有在资源被征税时才会进行强选择。
To what degree does our representation of the immediate world depend solely on its relevance to what we are currently doing? We examined whether relevance per se can cause "blindness," even when there is no resource limitation. In a novel paradigm, people looked at a colored circle surrounded by a differently colored ring the task relevance of which was previously manipulated-Land Were subsequently asked to identify these colors. Whereas knowledge of the task-relevant color was near perfect, up to a quarter of the participants could not name the color of the irrelevant stimulus, even though a control experiment indicated there were sufficient resources to process both stimuli. The results are a first demonstration of blindness when mental resources are clearly available and challenge attentional theories predicting strong selection only when resources are taxed.
