对变化检测的研究增加了我们对注意力、感知和记忆的理解。在两个创新的实验中，我们表明，变化检测现象可以用来检查其他领域的认知，特别是，在口语单词的语言和索引信息的处理。一种假设认为，认知资源必须用于处理索引信息，而另一种假设认为，它比语言信息的加工速度更慢。参与者进行了词汇决策任务，并被问到是否声音呈现的刺激改变。在词汇决策任务中，使用了与真实的单词相似的非单词，以鼓励参与者改变认知资源/处理时间的量。对类词非词进行词汇判断需要更多的认知资源/加工时间。听到类似单词的非单词的参与者更有可能在发生变化时检测到变化（实验1），并且更有信心当声音没有变化时声音是相同的（实验2）。这些结果表明，索引信息的处理速度比语言信息更慢，并展示了变化检测如何为认知的其他领域提供洞察力。
Studies of change detection have increased our understanding of attention, perception, and memory. In two innovative experiments we showed that the change detection phenomenon can be used to examine other areas of cognition—specifically, the processing of linguistic and indexical information in spoken words. One hypothesis suggests that cognitive resources must be used to process indexical information, whereas an alternative suggests that it is processed more slowly than linguistic information. Participants performed a lexical decision task and were asked whether the voice presenting the stimuli changed. Nonwords varying in their likeness to real words were used in the lexical decision task to encourage participants to vary the amount of cognitive resources/processing time. More cognitive resources/processing time are required to make a lexical decision with word-like nonwords. Participants who heard word-like nonwords were more likely to detect the change when it occurred (Experiment 1) and were more confident that the voice was the same when it did not change (Experiment 2). These results suggest that indexical information is processed more slowly than linguistic information and demonstrate how change detection can provide insight to other areas of cognition.
