注意瞬脱实验（AB）的第一个任务（两个任务都是非快速的）和快速AB范式（SAB;任务（1）中的快速即时反应）中刺激和反应选择的数量是不同的。在AB范式（实验1）中，任务（2）的准确性不依赖于备选项的数量;然而，在SAB范式（实验2-3）中，随着备选项的增加，任务（2）的准确性降低。任务（1）中较长的响应时间与任务2中较低的准确性相关。结果表明，任务（1）中的中央处理的持续时间调节AB现象。结果进行了讨论的背景下，中央干扰理论。该理论提供了一个统一的理论框架，在此框架内，AB和SAB范式，探测信号范式，心理不应期范式可以进行分析和理解。
The number of stimulus and response alternatives was varied in the 1st task of an attentional blink (AB) experiment (both tasks unspeeded) and in a speeded AB paradigm (SAB; speeded immediate response in Task(1)). Accuracy in Task(2) did not depend on the number of alternatives in the AB paradigm (Experiment 1); however, accuracy in Task2 decreased as alternatives increased in the SAB paradigm (Experiments 2-3). Longer response times in Task(1) were associated with lower accuracy in Task2. The results suggest that the duration of central processing in Task(1) modulates the AB phenomenon. The results are discussed in the context of the central interference theory. The theory provides a unified theoretical framework within which the AB and SAB paradigms, the probe signal paradigm, and the psychological refractory period paradigm can be analyzed and understood.
