工作记忆如何支持双任务表现是一个长期争论的焦点。之前关于这一主题的大多数研究都集中在参与者的表现数据上。在三个实验中，我们调查了参与者在单任务和双任务条件下报告策略的变化是否可以通过提供新的见解来解决这一争论，从而导致富有成效的理论整合，而不是通过试图确定哪种理论最适合数据而使争论持续下去。结果表明，发音抑制与使用排练和聚类策略的报告减少有关，但与使用视觉策略的报告增加有关。与单任务相比，双任务下对记忆的细化和聚类策略较少。在双重任务和发音抑制下，更多的参与者报告试图记住更少的记忆项目（记忆减少策略）。对于算术验证，发音抑制和双重任务导致计数策略的报告减少，而算术知识检索策略的报告增加。研究者认为，实验者不应该假设参与者在不同的实验条件下以相同的方式执行相同的任务，而仔细研究参与者如何根据实验条件的变化改变他们的策略，对于解决理论挑战具有相当大的潜力。有人进一步认为，这种方法指出了尝试整合而不是扩散工作记忆理论的价值。
How working memory supports dual-task performance is the focus of a long-standing debate. Most previous research on this topic has focused on participant performance data. In three experiments, we investigated whether changes in participant-reported strategies across single-and dual-task conditions might help resolve this debate by offering new insights that lead to fruitful integration of theories rather than perpetuating debate by attempting to identify which theory best fits the data. Results indicated that articulatory suppression was associated with reduced reports of the use of rehearsal and clustering strategies but to an increase of the reported use of a visual strategy. Elaboration and clustering strategies were reported less for memory under dual task compared with single task. Under both dual task and articulatory suppression, more participants reported attempting to remember fewer memory items than were presented (memory reduction strategy). For arithmetic verification, articulatory suppression and dual task resulted in a reduction in reports of a counting strategy and an increase in reports of a retrieval strategy for arithmetic knowledge. It is argued that experimenters should not assume that participants perform the same task in the same way under different experimental conditions and that carefulty investigation of how participants change their strategies in response to changes in experimental conditions has considerable potential for resolving theoretical challenges. It is argued further that this approach points toward the value of attempting to integrate rather than proliferate theories of working memory.
