Human Attention in Digital Environments: Human attention and its implications for human–computer interaction

Abstract: Remembering planned activities, resuming tasks previously interrupted, recalling the names of colleagues, sustaining focused performance under the pressure of interruptions, ensuring that we don't miss important information…these are only a few examples of critical activities whose performance is guided by attentional processes. This chapter proposes that knowledge about attentional processes can help us design systems that support users in situations such as those described above. The first part of the chapter gives an overview of some of the essential theoretical findings about human attention. The second part analyses attentional breakdowns and how those theoretical findings may be applied in order to design systems that either help avoid attentional breakdowns or assist in recovering from them . Introduction Current information and communication technologies concentrate on providing services to users performing focused activities. However, focused activity is no longer the norm. Users are often interrupted, they switch between the contexts of different devices and tasks, maintain awareness about the activity of distant collaborators and manage very large quantities of information. All this results in high cognitive load that may hinder users' overall achievements. In order to address interaction in a more realistic manner, we have been working on the development of systems that are capable of supporting the processes that govern human cognitive resources allocation: attentional processes.

Time to see the bigger picture: Individual differences in the attentional blink.

Abstract: If two to-be-identified targets are presented in close temporal succession, identification for the second target is typically impaired. This attentional blink (AB) phenomenon has long been considered as a robust, universal cognitive limitation. However, more recent studies have demonstrated that AB task performance greatly differs between individuals, with some individuals even showing no AB in certain paradigms. Several studies have focused on these individual differences in an attempt to reveal the mechanism underlying the AB, but an overview of this approach is currently missing. Here, by reviewing studies regarding individual differences in AB task performance, we investigate how individual differences have contributed to our understanding of the AB. We show that the individual differences AB literature provides reliable indications that the AB is a multifaceted phenomenon that presumably arises from a combination of factors; individuals with higher levels of executive working memory (WM) functioning and broad attentional focus perform better in the AB paradigm than individuals with lower executive functioning of WM and narrow attentional focus. As it turns out, seeing the bigger picture certainly seems helpful for AB task performance.

Memory operations in rapid serial visual presentation

Abstract: Short-term memory (STM) has often been considered to be a central resource in cognition. This study addresses its role in rapid serial visual presentation (RSVP) tasks tapping into temporal attention *the attentional blink (AB). Various STM operations are tested for their impact on performance and, in particular, on the AB. Memory tasks were found to exert considerable impact on general performance but the size of the AB was more or less immune to manipulations of STM load. Likewise, the AB was unaffected by manipulating the match between items held in STM and targets or temporally close distractors in the RSVP stream. The emerging picture is that STM resources, or their lack, play no role in the AB. Alternative accounts assuming serial consolidation, selection for action, and distractor-induced task-set interference are discussed.
