通过研究个体化言语负荷对视觉工作记忆任务的影响，我们研究了工作记忆是否更好地被特定模态存储或一般注意力资源捕获。使用视觉测量，其允许量化工作记忆中表征的精确度。贝叶斯分析被用来对比我们的数据的可能性，假设一个小的与一个大的影响，预测不同的帐户。我们发现的证据表明，言语负荷对视觉精度和二进制特征回忆的影响很小。结果是不确定的双任务对言语准确性和回忆连续目标功能的概率影响的大小。这些结果，在一定程度上，支持工作记忆的多成分帐户。还报告了对所选效应区间如何影响结果的分析，突出了在文献中进行具体预测的重要性。
By investigating the effect of individualized verbal load on a visual working memory task, we investigated whether working memory is better captured by modality-specific stores or a general attentional resource. A visual measure was used that allows for the precision of representations in working memory to be quantified. Bayesian analyses were employed to contrast the likelihood of our data assuming a small versus a large effect, as predicted by the differing accounts. We found evidence that the effect of verbal load on visual precision and binary feature recall was small. The results were indeterminate for the size of the dual task effect on verbal accuracy and the probability of recalling a continuous target feature. These results, in part, support a multiple component account of working memory. An analysis of how the chosen effect intervals affect the results is also reported, highlighting the importance of making specific predictions in the literature.
