Top-down visual attention filters undesired stimuli while selected information is afforded the
lion's share of limited cognitive resources. Multiple selection mechanisms can be deployed …

The ability to select and combine multiple sensory inputs in support of accurate decisions is
a hallmark of adaptive behaviour. Attentional selection is often needed to prioritize task …

Top-down visual attention selectively filters sensory input so relevant information receives
preferential processing. Feature-based attention (FBA) enhances the representation of …

Performance on a visual task is improved when attention is directed to relevant spatial
locations or specific visual features. Spatial attention can be directed either voluntarily …

Previous research has identified three mechanisms that guide visual attention: bottom-up
feature contrasts, top-down tuning, and the trial history (eg, priming effects). However, only …

Real-world visual search targets are frequently imperfect perceptual matches to our internal
templates. For example, a friend on different occasions will have different clothes, hairstyles …

To characterize internal processes of an observer conducting perceptual tasks, we
developed an observer model that combines the perceptual template model (PTM), the …

Attention selects objects in a scene for cognitive processing. A growing body of evidence
has been used to argue that observers are able to narrowly restrict attentional selection to …

Selective attention improves sensory processing of relevant information but can also impact
the quality of perception. For example, attention increases visual discrimination performance …

Most theories of visual search maintain that attention is selectively tuned to the attributes of
the search target (eg, orange). Conversely, according to the relational account, attention is …
