When participants are asked to recall a short list of words in any order that they like, they tend to initiate recall with the first list item and proceed in forward order, even when this is not a task requirement. The current research examined whether this tendency might be influenced by varying the number of items that are to be recalled. In 3 experiments, participants were presented with short lists of between 4 and 6 words and instructed to recall 1, 2, 3, or all of the items from the lists. Data were collected using immediate free recall (IFR, Experiment 1), immediate serial recall (ISR, Experiment 2), and a variant of ISR that we call ISR-free (Experiment 3), in which participants had to recall words in their correct serial positions but were free to output the words in any order. For all 3 tasks, the tendency to begin recall with the first list item occurred only when participants were required to recall as many items from the list as they could. When participants were asked to recall only 1 or 2 items, they tended to initiate recall with end-of-list items. It is argued that these findings show for the first time a manipulation that eliminates the initial tendency to recall in forward order, provide some support for recency-based accounts of IFR and help explain differences between single-response and multiple-response immediate memory tasks.

当要求参与者以他们喜欢的任何顺序回忆一小串单词时,他们倾向于从列表的第一个项目开始回忆,并按顺序进行,即使这不是任务要求。当前的研究考察了这种倾向是否可能受到改变要回忆项目数量的影响。在3个实验中,向参与者呈现4到6个单词的短列表,并指示他们回忆列表中的1个、2个、3个或所有项目。使用即时自由回忆(IFR,实验1)、即时系列回忆(ISR,实验2)以及我们称为ISR-自由回忆(实验3)的ISR变体收集数据,在ISR-自由回忆中,参与者必须按正确的顺序回忆单词,但可以自由地以任何顺序输出单词。对于所有这3项任务,只有当要求参与者尽可能多地回忆列表中的项目时,才会出现从列表的第一个项目开始回忆的倾向。当要求参与者只回忆1个或2个项目时,他们倾向于从列表末尾的项目开始回忆。有人认为,这些发现首次表明了一种消除按顺序向前回忆的初始倾向的操作,为基于近因效应的IFR解释提供了一些支持,并有助于解释单反应和多反应即时记忆任务之间的差异。(PsycINFO数据库记录)
