Neural dynamics of shifting attention between perception and working-memory contents

The Intensity of Internal and External Attention Assessed with Pupillometry

Journal of Cognition, Год журнала: 2024, Номер 7(1), С. 8 - 8

Опубликована: Янв. 9, 2024

Not only is visual attention shifted to objects in the external world, can also be directed memory. We have recently shown that pupil size indexes how strongly items are attended externally, which was reflected more precise encoding into working Using a retro-cuing paradigm, we here replicated this finding by showing stronger constrictions during were reflective of depth encoding. Importantly, extend previous work revealed intensity internal toward content stored Specifically, dilation prioritization one among multiple internally representations predicted precision prioritized item. Furthermore, dynamics pupillary responses and independently determined internalized representations. Our results show both not all-or-none processes, but should rather thought as continuous resources deployed at varying intensities. The employed pupillometric approach allows unravel intricate interplay between their effects on

Abstract In everyday tasks, our focus of attention shifts seamlessly between contents in the sensory environment and internal memory representations. Yet, research has mainly considered external isolation. We used magnetoencephalography to compare neural dynamics shifting visual within vs. domains. Participants performed a combined perception working-memory task which two sequential cues guided upcoming (external) or memorised (internal) information. Critically, second cue could redirect content same alternative domain as first cue. Multivariate decoding unveiled distinct patterns human brain activity when Brain distinguishing within- from between-domain was broadly distributed highly dynamic. Intriguingly, crossing domains did not invoke an additional stage prior shifting. Alpha lateralisation, canonical marker spatial attention, showed no delay redirected domain. Instead, evidence suggested that states associated with given linger influence subsequent Our findings provide insights into govern attentional working memory. Significance Statement During almost every natural behaviour, regularly contents. Although systems mechanisms control modulation have been heavily studied isolation, how crosses these remains uncharted territory. Here, we study investigate Using novel experimental design, isolated reveal early, dynamic, distinguish shifts, offering fascinating initial insights, opening new questions for investigation.

Affect-congruent attention modulates generalized reward expectations

PLoS Computational Biology, Год журнала: 2023, Номер 19(12), С. e1011707 - e1011707

Опубликована: Дек. 21, 2023

Positive and negative affective states are respectively associated with optimistic pessimistic expectations regarding future reward. One mechanism that might underlie these affect-related expectation biases is attention to positive- versus negative-valence features (e.g., attending the positive reviews of a restaurant its expensive price). Here we tested effects experimentally induced affect on feature-based in 120 participants completing compound-generalization task eye-tracking. We found participants' reward for novel compound stimuli were modulated an affect-congruent way: induction increased compounds, whereas decreased expectations. Computational modelling eye-tracking analyses each revealed driven by changes allocation high- low-value compounds. These results provide mechanistic insight into process which produces generalized

Decoding intelligence via symmetry and asymmetry

Abstract Humans use pictures to model the world. The structure of a picture maps mind space form concept. When an internal matches corresponding external structure, observation functions. Whether effective or not, is self-consistent. In epistemology, people often differ from each other in terms whether concept probabilistic certain. Based on effect presented IG and pull anti algorithm, we attempt provide comprehensive answer this problem. Using characters hidden structures, explain difference between macro micro levels same semantics probability. addition, importance attention highlighted through combination symmetry asymmetry included mechanism chaos collapse revealed model. Because subject involved expression object, representationalism not complete. However, undoubtedly reach consensus based objectivity representation. Finally, suggest that emotions could be used regulate cognition.

Sensory Input Matching Visual Working Memory Guides Internal Prioritization

Abstract Adaptive behavior necessitates the prioritization of most relevant information in environment (external) and memory (internal). Internal is known to guide selection external sensory input, but reverse may also be possible: Does memorized material? Here we addressed whether reappearing input matching visual working (VWM) facilitates other non-reappearing items. Participants (total n = 72) three orientations. Crucially some, not all, items maintained VWM were made available again environment. These never had reproduced later. Experiment 1 showed that reappearance all one item benefited accuracy speed same extent as a spatial retro cue. This shows memory-matching allow for dynamic another item. What aspects drive this effect? 2 demonstrated was facilitated if matched content terms both location orientation. Sensory fully likely processed more efficiently, possibly leading stronger content. We robustness our findings 3. propose link between processing bidirectional: internal representations which turn subserve adaptive behavior.

Internal Coupling: Eye Behavior Coupled to Visual Imagery

Neuroscience & Biobehavioral Reviews, Год журнала: 2024, Номер 165, С. 105855 - 105855

Опубликована: Авг. 15, 2024

Our eyes do not only respond to visual perception but also internal cognition involving imagery, which can be referred as coupling. This review synthesizes evidence on coupling across diverse domains including episodic memory and simulation, visuospatial memory, numerical cognition, object movement, body brightness imagery. In each domain, eye movements consistently reflect distinct aspects of mental imagery typically akin those seen in corresponding experiences. Several findings further suggest that may coincide with supports evidenced by improved cognitive performance. Available theoretical accounts serve at least two functional roles imagery: facilitating reconstruction indicating shifts attention. Moreover, recent insights into the neurobiology highlight substantially shared neural pathways externally internally directed cognition. The concludes identifying open questions promising avenues for future research such exploring moderating context individual differences
