Working memory refers to an intriguing and essential problem in cognitive science: How does the brain succeed in maintaining information for certain duration and perform mental operations on the stored information? An important avenue in tackling this issue stems from the relatively well-defined domain of selective attention. The role of selective attention in working memory has become increasingly dominant over the last decades as information stored in working memory has been shown to modulate (external) selective attention processing-and vice versa (for reviews see e.g., Awh and Jonides, 2001;Kiyonaga and Egner, 2013). Indeed, whereas attentional components in traditional working memory models typically relate to executive mechanisms assumed to control and supervise dedicated working memory buffers (e.g., Baddeley and Hitch, 1974;Baddeley, 2000), more recent models envisage working memory as directly and specifically emerging from selective attention turned to long-term memory representations (e.g., Cowan, 1999;Oberauer, 2009).Despite the prominent role that selective attentional models of working memory play in current cognitive science, there is still much work to do in determining the precise implications of these models for specific aspects and characteristics of working memory-in both healthy and neuropsychological populations. The current Research Topic in Frontiers in Human Neuroscience aims to contribute to this challenge and offers novel empirical observations, state-of-the-art reviews, and intriguing theoretical proposals that illuminate the interplay between selective attention and working memory. In general, these contributions can be categorized into three broad classes of studies:First, the majority of the papers involve empirical or theoretical efforts directly aimed at a better understanding of the interplay between selective attention and working memory. Camos and Barrouillet (2014) review the literature and identify attentional and non-attentional mechanisms that contribute to the maintenance of information in verbal working memory. Vergauwe and Cowan (2014) conclude on the basis of a review that attentional search within working memory happens at a high-speed processing rate of about 35-40 ms per item, and propose that this rate reflects the involvement of gamma oscillations in the brain. Pedale and Santangelo (2015) investigated to what degree sensory saliency of the item information during encoding modulates the current contents of WM during recollection. van Moorselaar et al. (2015) focus on the reverse relationship and investigate the time course in which information in working memory is protected against interfering visual input. Zokaei et al. (2014) tackle an outstanding question about the representational state of items in working memory that are not prioritized by attentional focusing. Abrahamse et al. (2014) hypothesize that serial order coding in verbal working memory appeals to the spatial attention system and thereby can be synthesized with selective attentional models on working...
