工作记忆的理论在处理和储存之间的关系上往往存在分歧，特别是在它们对基于注意力的有限资源的依赖程度上。有些人认为资源的分离和专门化导致在完成正在进行的处理任务时对记忆的干扰最小，而另一些人则认为并发任务中涉及的资源有更大的重叠。在这里，我们提出了四个实验，调查的存在或不存在的双重任务成本的记忆和处理。这些实验是在对抗性合作中进行的，来自三个对立理论的研究人员合作设计了一组实验，并根据他们的每个模型提供了差异预测。与会者进行延迟召回的听觉和视觉呈现的字母和算术验证任务，无论是作为单一的任务或算术验证任务之间的介绍和召回的字母序列。单任务和双任务条件下完成，并没有并发发音抑制。一个一致的模式，双任务和抑制成本的记忆，较小或无效的影响处理。观察到的数据并不完全符合任何一个框架，每个模型在预测数据模式方面都取得了部分成功。每个模型的影响进行了讨论，目的是为未来的研究，以调查是否有一些组合的模型和他们的假设可以提供一个更全面的解释模式的影响，在这里观察到的，并在相关的先前研究与每个理论框架。
Theories of working memory often disagree on the relationships between processing and storage, particularly on how heavily they rely on an attention-based limited resource. Some posit separation and specialization of resources resulting in minimal interference to memory when completing an ongoing processing task, while others argue for a greater overlap in the resources involved in concurrent tasks. Here, we present four experiments that investigated the presence or absence of dual-task costs for memory and processing. The experiments were carried in an adversarial collaboration in which researchers from three opposing theories collaboratively designed a set of experiments and provided differential predictions in line with each of their models. Participants performed delayed recall of aurally and visually presented letters and an arithmetic verification task either as single tasks or with the arithmetic verification task between presentation and recall of letter sequences. Single- and dual-task conditions were completed with and without concurrent articulatory suppression. A consistent pattern of dual-task and suppression costs was observed for memory, with smaller or null effects on processing. The observed data did not fit perfectly with any one framework, with each model having partial success in predicting data patterns. Implications for each of the models are discussed, with an aim for future research to investigate whether some combination of the models and their assumptions can provide a more comprehensive interpretation of the pattern of effects observed here and in relevant previous studies associated with each theoretical framework.
