Covert spatial attention (without concurrent eye movements) improves performance in many
visual tasks (eg, orientation discrimination and visual search). However, both covert …

To explore the relative contributions of higher-order and primary visual cortex (V1) to visual
perception, we compared cats' behavioral and V1 neuronal contrast sensitivity functions …

Crowding refers to the failure to identify a peripheral object due to its proximity to other
objects (flankers). This phenomenon can lead to reading and object recognition impairments …

In our daily lives, the visual system receives a plethora of visual information that competes
for the brain's limited processing capacity. Nevertheless, not all visual information is useful …

Perceptual confidence typically corresponds to accuracy. However, observers can be
overconfident relative to accuracy, termed “subjective inflation.” Inflation is stronger in the …

Many models of attention assume that categorization (the individuation of events based on
the feature dimension relevant for response selection) occurs only after an object has been …

It has been found that a spatial cue in perception causes benefits through target facilitation
at low external noise but noise reduction at high external noise. Assuming that mnemonic …

Abstract Purpose of Review The magnocellular theory is one of the well-accepted
neurobiological theories to explain developmental dyslexia. However, criticism remains on …

The role of attention in task-irrelevant perceptual learning has been contested. Attention has
been studied in the past using distractor-type manipulations. Hence, during an initial …

Attention alters how we perceive our surroundings by selectively prioritizing a subset of
visual information at the expense of the rest. Covert spatial attention selects behaviorally …
