387名受试者被视觉呈现6个字母的序列，以便立即回忆。错误表现出系统的关系，以原始的刺激。这是为了满足即时记忆衰退理论的要求。同样的字母词汇被用在一项测试中，要求受试者在白色噪音背景下识别所说的字母。在听力测试中出现混淆的字母和在回忆中出现混淆的字母之间存在高度显著的相关性，并结合这些结果讨论了神经噪声在回忆中的作用。有人进一步认为，信息理论是不足以解释的记忆广度，因为刺激集的性质，这可以定量定义，以及每个项目的信息，很可能是一个决定性因素。
Sequences of 6 letters of the alphabet were visually presented for immediate recall to 387 subjects. Errors showed a systematic relationship to original stimuli. This is held to meet a requirement of the decay theory of immediate memory.The same letter vocabulary was used in a test in which subjects were required to identify the letters spoken against a white noise background. A highly significant correlation was found between letters which confused in the listening test, and letters which confused in recall.The role of neurological noise in recall is discussed in relation to these results. It is further argued that information theory is inadequate to explain the memory span, since the nature of the stimulus set, which can be defined quantitatively, as well as the information per item, is likely to be a determining factor.
