Impact of vocal load on breathiness: Perceptual evaluation [PDF]

Logopedics Phoniatrics Vocology, 2014
To evaluate the impact on voice of 2 hours of continuous oral reading.Fifty normophonic women underwent two sessions of voice loading in which the required intensity level varied: 60-65 dB(A) for the first session, and 70-75 dB(A) for the second session.

Visual perceptual load induces inattentional deafness [PDF]

Attention, Perception, & Psychophysics, 2011
In this article, we establish a new phenomenon of "inattentional deafness" and highlight the level of load on visual attention as a critical determinant of this phenomenon. In three experiments, we modified an inattentional blindness paradigm to assess inattentional deafness. Participants made either a low- or high-load visual discrimination concerning

The Competitive Influences of Perceptual Load and Working Memory Guidance on Selective Attention.

PLoS ONE, 2015
The perceptual load theory in selective attention literature proposes that the interference from task-irrelevant distractor is eliminated when perceptual capacity is fully consumed by task-relevant information.

Predicting human complexity perception of real-world scenes [PDF]

Royal Society Open Science, 2020
Perceptual load is a well-established determinant of attentional engagement in a task. So far, perceptual load has typically been manipulated by increasing either the number of task-relevant items or the perceptual processing demand (e.g.

Evolutionary Relevance Facilitates Visual Information Processing

Evolutionary Psychology, 2013
Visual search of the environment is a fundamental human behavior that perceptual load affects powerfully. Previously investigated means for overcoming the inhibitions of high perceptual load, however, generalize poorly to real-world human behavior.

Opposite effects of perceptual and working memory load on perceptual filling-in of an artificial scotoma [PDF]

Cognitive Neuroscience, 2011
A target presented on a background of dynamic noise disappears from awareness after a few seconds of maintained peripheral viewing. Whereas the effects of bottom-up factors in such filling-in are well documented, the roles of different top-down functions remain relatively unexplored.

Perceptual bias in Gestalt grouping by proximity affected by visual working memory load

Acta Psychologica
Basic perceptual processes, including perceptual grouping, are subject to bias. Bias for cardinal orientations interferes with Gestalt grouping by proximity in dot lattices.

Unconscious orientation processing depends on perceptual load

Journal of Vision, 2008
The effects of perceptual load on the level of adaptation to task-irrelevant and invisible oriented gratings were examined. Participants performed a task at fixation under conditions of low (detecting color targets) or high (detecting conjunctions of color and shape) perceptual load.

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

Frontiers 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 ...

Accurate expectancies diminish perceptual distraction during visual search

Frontiers 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.
