Cognitive load effects on early visual perceptual processing [PDF]

open access: yesAttention, Perception, & Psychophysics, 2018
Contrast-based early visual processing has largely been considered to involve autonomous processes that do not need the support of cognitive resources. However, as spatial attention is known to modulate early visual perceptual processing, we explored whether cognitive load could similarly impact contrast-based perception.

Memory for symmetry and perceptual binding in patients with schizophrenia [PDF]

open access: yes, 2013
The present study investigated the use of perceptual binding processes in schizophrenic (SC) patients and matched healthy controls, by examining their performance on the recall of symmetrical (vertical, horizontal and diagonal) and asymmetrical patterns ...

Linking inter-individual differences in the perceptual load effect to spontaneous brain activity

open access: yesFrontiers in Human Neuroscience, 2015
Previous researches have widely demonstrated that the interference from peripheral distractor will decrease when the task load is high. However, no study to date has paid attention to the individual differences in perceptual load effect and little is ...

Distracted by pleasure: effects of positive versus negative valence on emotional capture under load [PDF]

open access: yes, 2016
We report 3 experiments examining the effects of positive versus negative valence and perceptual load in determining attention capture by irrelevant emotional distractors. Participants performed a letter search task searching for 1 of 2 target letters (X

Accurate expectancies diminish perceptual distraction during visual search

open access: yesFrontiers in Human Neuroscience, 2014
The load theory of visual attention proposes that efficient selective perceptual processing of task-relevant information during search is determined automatically by the perceptual demands of the display.

Blinded by the load: attention, awareness and the role of perceptual load [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2014
What is the relationship between attention and conscious awareness? Awareness sometimes appears to be restricted to the contents of focused attention, yet at other times irrelevant distractors will dominate awareness. This contradictory relationship has also been reflected in an abundance of discrepant research findings leading to an enduring ...

Low level perceptual, not attentional, processes modulate distractor interference in high perceptual Load displays: evidence from neglect/extinction

open access: yesFrontiers in Psychology, 2014
According to perceptual load theory (Lavie, 2005) distractor interference is determined by the availability of attentional resources. If target processing does not exhaust resources (with low perceptual load) distractor processing will take place ...

Visual Discrimination Accuracy across Reaction Time in Rats [PDF]

open access: yesAnimal Behavior and Cognition, 2020
Processing time, computational load, and stimulus strength interact in perceptual decisions. Studies with non-human primates and rodents have demonstrated that perceptual decisions are guided by stimulus processing as well as cognitive factors, such as ...
