What are the benefits of directed attention within verbal working memory?

Resumen

Information that is particularly relevant for upcoming behavior can be prioritized within working memory, by directing attention to it. Receiving focused attention during retention is assumed to be associated with specific benefits, such as increased memory performance and reduced vulnerability to perceptual distractions. This has been demonstrated in visuospatial working memory. Given the domain-general nature of the focus of attention, these benefits should extend to verbal working memory as well. This was tested in the current study. In particular, we examined and compared the effects of cue-based and reward-based prioritization in verbal working memory across a series of five preregistered experiments. These experiments varied in their memory materials, set size, interference, and memory task. Our results collectively revealed several key findings. Firstly, both cue-based and reward-based prioritization led to a clear and consistent memory boost for prioritized information in verbal working memory. Secondly, the memory boost induced by cue-based prioritization was mostly comparable to that induced by reward-based prioritization. Thirdly, memory for verbal information did not drastically suffer when exposed to perceptual interference. And lastly, the effect of perceptual interference on verbal information was not drastically influenced by whether the information was prioritized or not. Overall, this series of experiments contributes to understanding the consequences of directed attention in verbal working memory and highlights similarities and differences from findings in visuospatial working memory.
