Degraded stimulus visibility and the effects of perceptual load on distractor interference
Frontiers in Psychology, 2013 In this study we examined whether effects of perceptual load on the attentional selectivity are modulated by degradation of the visual input. According to the perceptual load theory, increasing task difficulty via degradation of stimulus visibility ...

Event related potentials reveal that increasing perceptual load leads to increased responses for target stimuli and decreased responses for irrelevant stimuli [PDF]
Frontiers in Human Neuroscience, 2008 Lavie and colleagues (1995, JEP:HPP 9: 497-) have suggested that perceptual processing is influenced by perceptual load. Specifically, relevant information receives additional processing in high load situations exhausting the available capacity.

Perceptual load modulates contour integration in conscious and unconscious states. [PDF]
PeerJ, 2019 Previous research has documented that contour detection and integration may either be affected by local features such as the distances between elements or by high-level cognitive factors such as attention in our visual system. Less is known about how low

Visual Perceptual Load Does Not Affect the Frequency Mismatch Negativity. [PDF]
Front Psychol, 2019 The mismatch negativity (MMN) has been of particular interest in auditory perception because of its sensitivity to auditory change. It is typically measured in an oddball task and is computed as the difference of deviant minus standard tones.

The influence of schizotypal traits on attention under high perceptual load [PDF]
Schizophrenia Research: Cognition, 2018 Schizophrenia Spectrum Disorders (SSD) are known to be characterised by abnormalities in attentional processes, but there are inconsistencies in the literature that remain unresolved.

No effects of attention or visual perceptual load on cochlear function, as measured with stimulus-frequency otoacoustic emissions. [PDF]
J Acoust Soc Am, 2019 The effects of selectively attending to a target stimulus in a background containing distractors can be observed in cortical representations of sound as an attenuation of the representation of distractor stimuli. The locus in the auditory system at which

Pupil size and search performance in low and high perceptual load. [PDF]
Cogn Affect Behav Neurosci, 2019 The ability to focus on a task while disregarding irrelevant information is an example of selective attention. The perceptual-load hypothesis argues that the occurrence of early or late selection mechanisms is determined by task-relevant perceptual load.

Evaluative pressure overcomes perceptual load effects
Psychonomic Bulletin & Review, 2015 International audiencePerceptual load has been found to be a powerful bottom-up determinant of distractibility, with high perceptual load preventing distraction by any irrelevant information. However, when under evaluative pressure, individuals exert top-

Perceptual load interacts with involuntary attention at early processing stages: Event-related potential studies [PDF]
NeuroImage, 2009 Perceptual load is known to influence the locus of attentional selection in the brain but through an unknown underlying mechanism. We used event-related potentials (ERPs) to investigate how perceptual load interacts with cue-driven involuntary attention.

The influence of visual flow and perceptual load on locomotion speed. [PDF]
Atten Percept Psychophys, 2018 Visual flow is used to perceive and regulate movement speed during locomotion. We assessed the extent to which variation in flow from the ground plane, arising from static visual textures, influences locomotion speed under conditions of concurrent ...
