Bundesen’s Theory of Visual Attention (TVA) has been around for approximately half a century. Its basic idea is that visual perception is biased competition of visual categorizations that race visual short-term memory. The biases stem from attentional and perceptual influences. TVA links observable data to theoretical concepts with mathematical rigor and helps to explain phenomena with quantitatively precise concepts. Progress in TVA might not be fast, but it is continuous and robust. This symposium covers recent developments in topics of basic and applied research. In the first session, Scharlau & Tünnermann survey recent advances with new stimuli and recording
settings. Connecting to this, Biermeier & Scharlau investigate attention capacity in mixed-reality settings. Poth & Schneider disentangle the speed of location and object processing. Tünnermann et al. show how simulations of visual foraging depend on dynamically adjusting spatial attention, and Blurton et al. discuss improvements in modeling cognitive control. The second session focuses on recent applications of TVA in clinical contexts: Ruiz-Rizzo et al. present the relationship between visual processing speed and cognitive complaints in older adults. Kattlun et al. investigate the role of visual-short-term memory in cognitive deficits of patients who survived severe sepsis. Martin et
al. demonstrate how fatigue relates to visual processing speed and pupillary unrest in post-COVID patients. Srowig et al. close by showing how visual short-term memory is associated with neuropsychological performance in patients at a high-risk for dementia.

Comparison of attention capacity across mixed realities

Without visual attention, we would be quickly overwhelmed by the mass of information surrounding us. Consequently, understanding attention matters not only to cognitive psychology but for example also to human-computer interaction research. Especially in mixed reality research, it is of broad interest to understand and therefore to be able to guide (visual) attention in complex environments. The basis to understand attention is a quantification of it. We have chosen a combination of a temporal order judgment task (for its ease of integration in many tasks) combined with a suitable TVA model to estimate attention capacity (TVA’s C) in Virtual Reality (VR), Augmented Reality (AR), and Reality (R) in a withing subject design. We compare the estimated C’s to decide whether First: the degree of virtuality has an influence on attention or Second: the different kinds of mixed reality have different effects on visual attention. At the end of the talk, we want to discuss challenges to measuring visual attention in mixed reality and how cognitive psychology and human-computer interaction can jointly benefit from interdisciplinary research on this topic.
