Rhythmic sampling revisited: experimental paradigms and neural mechanisms
Sampling of information is thought to be an important aspect of explorative behaviour.
Evidence for it has been gained in behavioural assessments of a variety of overt and covert …

Spatial and feature-selective attention have distinct, interacting effects on population-level tuning
Attention can be deployed in different ways: When searching for a taxi in New York City, we
can decide where to attend (eg, to the street) and what to attend to (eg, yellow cars) …

Cortical state dynamics and selective attention define the spatial pattern of correlated variability in neocortex
Correlated activity fluctuations in the neocortex influence sensory responses and behavior.
Neural correlations reflect anatomical connectivity but also change dynamically with …

Relative precision of top-down attentional modulations is lower in early visual cortex compared to mid-and high-level visual areas
S Park, JT Serences - Journal of Neurophysiology, 2022 - journals.physiology.org
Top-down spatial attention enhances cortical representations of behaviorally relevant visual
information and increases the precision of perceptual reports. However, little is known about …

[HTML][HTML] Increasing the spatial extent of attention strengthens surround suppression
M Kınıklıoğlu, H Boyaci - Vision Research, 2022 - Elsevier
Here we investigate how the extent of spatial attention affects center-surround interaction in
visual motion processing. To do so, we measured motion direction discrimination thresholds …

Dissociable neural mechanisms of selective visual information processing underlie the effects of attention on visual appearance and response bias
S Itthipuripat, P Wiwatphonthana, P Sawetsuttipan… - 2022 - researchsquare.com
It has been debated if attention can penetrate early perceptual representations to alter visual
appearance or it simply induces response biases. Here, we tested these alternative …

How do (perceptual) distracters distract?
T Dumbalska, K Rudzka, HE Smithson… - PLoS Computational …, 2022 - journals.plos.org
When a target stimulus occurs in the presence of distracters, decisions are less accurate. But
how exactly do distracters affect choices? Here, we explored this question using …
