Allenylidenphosphonium‐Ion: Ein Isoelektronisches Phosphor‐Analogon Von [3]Kumulen
Angewandte Chemie, Volume 137, Issue 21, May 19, 2025.Wir berichten über die erste isolobale und isoelektronische Integration eines Phosphoratoms in ein [3]Kumulen. Dieses trigonal‐planare Phosphoniumallenyliden zeigt außergewöhnliche Lewis‐Acidität durch ein π*‐Akzeptororbital und weist eine einzigartige Reaktivität durch eine reversible intramolekulare dearomative [2+2]‐Cycloaddition auf ...

The Focus of Attention in Visual Working Memory: Protection of Focused Representations and Its Individual Variation. [PDF]
PLoS ONE, 2016 Visual working memory can be modulated according to changes in the cued task relevance of maintained items. Here, we investigated the mechanisms underlying this modulation.

Frontiers 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-

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

Attention as selection for action defended
Philosophy 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.

Frontiers 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

Examining the lateralization of electrophysiological correlates of auditory awareness
Psychophysiology, Volume 61, Issue 11, November 2024.Abstract The neurological basis for perceptual awareness remains unclear, and theories disagree as to whether sensory cortices per se generate awareness. Critically, neural activity in the sensory cortices is only a neural correlate of consciousness (NCC) if it closely matches the contents of perceptual awareness.

Electrophysiological Correlates of Subitizing in Healthy Aging.
PLoS ONE, 2015 To understand the nature of age-related changes in enumeration abilities we measured two ERP responses -N2pc and CDA, associated respectively to attentive individuation and VWM- and posterior alpha band (8-15 Hz) event-related desynchronization (ERD ...

Attentional guidance by the contents of working memory and the N2PC component
The Journal of Neurobehavioral Sciences, 2015 Abstract The Biased Competition Model suggests that stimuli matching the contents of working memory increase the likelihood that memory-matching items will be attended. According to this account, the representations in working memory create an involuntary capture of attention toward memory-matching items in the visual field.

Target switch costs in visual search arise during the preparatory activation of target templates
Psychophysiology, Volume 61, Issue 11, November 2024.Abstract Prior research on task switching has shown that the reconfiguration of stimulus–response mappings across trials is associated with behavioral switch costs. Here, we investigated the effects of switching representations of target‐defining features in visual search (attentional templates).
