sonic gems exploring the potential of audio recording as a form of sentimental Memory Capture
BCS-HCI '08 Proceedings of the 22nd British HCI Group Annual Conference on People and Computers: Culture Creativity Interaction - Volume 1, 2008Co-Authors: Gerard Oleksik, Lorna M BrownAbstract:This paper presents an exploratory study exploring the potential of audio recording as a form of sentimental Memory Capture. Drawing on data from four family households, we spotlight participants' attitudes towards sounds and audio recording, their existing recording practices and the types of sounds that they record when given a digital sound recorder. The findings indicate that a variety of different sounds were important, for a diversity of reasons. The paper considers participants' experiences of listening back to sounds, illuminating some of the unique affordances of audio recordings as a form of sentimental Memory Capture. The paper finishes by exploring the design challenges which the study raises for the Capture, playback and archiving of sentimental audio.

Neural Dynamics of Cognitive Control over Working Memory Capture of Attention
Journal of Cognitive Neuroscience, 2019Co-Authors: Peter S. Whitehead, Tobias Egner, Marty G. WoldorffAbstract:The contents of working Memory (WM) guide visual attention toward matching features, with visual search being faster when the target and a feature of an item held in WM spatially overlap (validly cued) than when they occur at different locations (invalidly cued). Recent behavioral studies have indicated that attentional Capture by WM content can be modulated by cognitive control: When WM cues are reliably helpful to visual search (predictably valid), Capture is enhanced, but when reliably detrimental (predictably invalid), Capture is attenuated. The neural mechanisms underlying this effect are not well understood, however. Here, we leveraged the high temporal resolution of ERPs time-locked to the onset of the search display to determine how and at what processing stage cognitive control modulates the search process. We manipulated predictability by grouping trials into unpredictable (50% valid/invalid) and predictable (100% valid, 100% invalid) blocks. Behavioral results confirmed that predictability modulated WM-related Capture. Comparison of ERPs to the search arrays showed that the N2pc, a posteriorly distributed signature of initial attentional orienting toward a lateralized target, was not impacted by target validity predictability. However, a longer latency, more anterior, lateralized effect—here, termed the “contralateral attention-related negativity”—was reduced under predictable conditions. This reduction interacted with validity, with substantially greater reduction for invalid than valid trials. These data suggest cognitive control over attentional Capture by WM content does not affect the initial attentional-orienting process but can reduce the need to marshal later control mechanisms for processing relevant items in the visual world.

role of attentional tags in working Memory driven attentional Capture
Journal of Experimental Psychology: Human Perception and Performance, 2014Co-Authors: Hsuanfu ChaoAbstract:Recent studies have demonstrated that the contents of working Memory Capture attention when performing a visual search task. However, it remains an intriguing and unresolved question whether all kinds of items stored in working Memory Capture attention. The present study investigated this issue by manipulating the attentional tags (target or distractor) associated with information maintained in working Memory. The results showed that working Memory-driven attentional Capture is a flexible process, and that attentional tags associated with items stored in working Memory do modulate attentional Capture. When items were tagged as a target, they automatically Captured attention; however, when items were tagged as a distractor, attentional Capture was reduced.
