然而，一些关于口头列表的即时回忆的研究表明，它受到可以回忆的块的数量的限制（例如，N. Cowan， Z. Chen, & J. N. Rudder, 2004； E. Tulving & J. E. Patkau, 1962），其他研究表明，它受到要回忆的材料长度的限制（例如，A. D. Baddeley， N. Thomson, & M. Buchanan, 1975）。作者通过教授单词之间的新配对联想来创建两个单词块来研究这个问题。结果表明，块容量限制和长度限制都在起作用。对于12个单词列表的自由记忆，6个预先学习的对和6个预先暴露的单词可以被回忆起来，这表明有块限制。然而。对于8个单词列表的顺序记忆，4个预学习对和8个预暴露单单词可以被记忆，这表明记忆长度是有限制的。其他条件产生了中间结果，表明有时这两个限制可能同时起作用。
Whereas some research on immediate recall of verbal lists has suggested that it is limited by the number of chunks that can be recalled (e.g., N. Cowan, Z. Chen, & J. N. Rudder, 2004; E. Tulving & J. E. Patkau, 1962), other research has suggested that it is limited by the length of the material to be recalled (e.g., A. D. Baddeley, N. Thomson, & M. Buchanan, 1975). The authors investigated this question by teaching new paired associations between words to create 2-word chunks. The results suggest that both chunk capacity limits and length limits come into play. For the free recall of 12-word lists, 6 pre-learned pairs could be recalled about as well as 6 pre-exposed singletons, suggesting a chunk limit. However. for the serially ordered recall of 8-word lists, 4 pre-learned pairs could be recalled about as well as 8 pre-exposed singletons, suggesting a length limit. Other conditions yielded intermediate results suggesting that sometimes both limits may operate together.
