在即时记忆任务中，字母的声学相似性和中立性随着反应前缀和刺激后缀以及作为记忆序列的成员而变化。32名受试中的每一位都朗读了160个视觉呈现的列表，这些列表由随机从声学相似子集(BCDGPTVZ)和中性子集(HJLNRXQY)中选择的字母组成，然后进行有序的语音回忆。一半受试者在反应前缀、刺激后缀和修改后的刺激后缀条件中五次接收到来自听觉相似子集的每个字母作为冗余元素(附加字母)，而另一半受试者相应地接收来自中性子集的字母。基于追溯干扰对冗余字母与记忆序列成员相似性的解释的预测不被支持。此外，刺激后缀对序列中最后一项的干扰程度与该后缀的空间分隔无关。
The acoustic similarity and neutrality of letters was varied as response prefixes and stimulus suffixes and as members of a memory series in an immediate memory task. Each of 32 Ss vocalized 160 visually presented lists composed of randomly selected letters from an acoustically similar subset (BCDGPTVZ) and a neutral subset (HJLNRXQY), followed by ordered vocal recall. Half the Ss received each letter from the acoustically similar subset five times as a redundant element (additional letter) in a response prefix, a stimulus suffix, and a modified stimulus suffix condition, while the other half correspondingly received letters from the neutral subset. Predictions based on retroactive interference explanations of the similarity of the redundant letters to members of a memory series failed to be supported. In addition, the extent to which a stimulus suffix interferes with the final items in a series is independent of the spatial separation of that suffix.
