An EEG study of detection without localisation in change blindness [PDF]

open access: yes, 2019
Previous studies of change blindness have suggested a distinction between detection and localisation of changes in a visual scene. Using a simple paradigm with an array of coloured squares, the present study aimed to further investigate differences in ...

Fast detection of covert visuospatial attention using hybrid N2pc and SSVEP features [PDF]

open access: yesJournal of Neural Engineering, 2016
Detecting the shift of covert visuospatial attention (CVSA) is vital for gaze-independent brain-computer interfaces (BCIs), which might be the only communication approach for severely disabled patients who cannot move their eyes. Although previous studies had demonstrated that it is feasible to use CVSA-related electroencephalography (EEG) features to ...

Allenylidene Phosphonium Ion: An Isoelectronic Phosphorus Analogue of [3]Cumulene

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 21, May 19, 2025.
We report the first isolobal and isoelectronic incorporation of a phosphorus atom into a [3]cumulene. This trigonal planar phosphonium allenylidene demonstrates exceptional Lewis acidity via a π* acceptor orbital and exhibits unique reactivity through a reversible intramolecular dearomative [2 + 2] cycloaddition reaction.

Detecting the presence of a singleton involves focal attention [PDF]

open access: yes, 2008
It has been claimed that the detection of a feature singleton can be based on activity in a feature map that allows coarse coding that something unique is present in the visual field. In the present study, participants detected the presence or absence of

Dynamic weighting of feature dimensions in visual search: behavioral and psychophysiological evidence [PDF]

open access: yes, 2012
Dimension-based accounts of visual search and selection have significantly contributed to the understanding of the cognitive mechanisms of attention. Extensions of the original approach assuming the existence of dimension-based feature contrast saliency ...

Attention as selection for action defended

open access: yesPhilosophy and Phenomenological Research, Volume 110, Issue 2, Page 421-441, March 2025.
Abstract Attention has become an important focal point of recent work in ethics and epistemology, yet philosophers continue to be noncommittal about what attention is. In this paper, I defend attention as selection for action in a weak form, namely that selection for action is sufficient for attention.

The attentive homunculus: ERP evidence for somatotopic allocation of attention in tactile search [PDF]

open access: yes, 2016
Our brain constantly receives tactile information from the body’s surface. We often only become aware of this information when directing our attention towards the body.

Neural Mechanism of Repeated Transcranial Magnetic Stimulation to Enhance Visual Working Memory in Elderly Individuals With Subjective Cognitive Decline

open access: yesFrontiers in Neurology, 2021
Visual working memory (VWM), the core process inherent to many advanced cognitive processes, deteriorates with age. Elderly individuals usually experience defects in the processing of VWM. The dorsolateral prefrontal cortex is a key structure for the top-

Contextual Valence and Sociality Jointly Influence the Early and Later Stages of Neutral Face Processing

open access: yesFrontiers in Psychology, 2016
Recent studies have demonstrated that face perception is influenced by emotional contextual information. However, because facial expressions are routinely decoded and understood during social communication, sociality should also be considered—that is, it

Temporal characteristics of the influence of punishment on perceptual decision making in the human brain [PDF]

open access: yes, 2013
Perceptual decision making is the process by which information from sensory systems is combined and used to influence our behavior. In addition to the sensory input, this process can be affected by other factors, such as reward and punishment for correct
