Auditory temporal resolution and backward masking in musicians with absolute pitch

open access: yesFrontiers in Neuroscience, 2023
Among the many questions regarding the ability to effortlessly name musical notes without a reference, also known as absolute pitch, the neural processes by which this phenomenon operates are still a matter of debate.

Summation versus suppression in metacontrast masking: On the potential pitfalls of using metacontrast masking to assess perceptual–motor dissociation [PDF]

open access: yes, 2014
International audienceA briefly flashed target stimulus can become "in-visible" when immediately followed by a mask-a phenomenon known as backward masking, which constitutes a major tool in the cognitive sciences.

Perceptual masking of spondees by combinations of talkers [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1975
Masked threshold for spondees were obtained in (1) steady-state speech spectrum noise, (2) speech spectrum noise modulated by seven talker combinations, and (3) the seven talker combinations. These combinations were 1, 2, 3, 16, 32, 64, and 128 voices speaking continuous discourse. The longterm spectra of all maskers were equalized to a common level by

Crossing the midline: reducing attentional deficits via interhemispheric interactions [PDF]

open access: yes, 2005
Patients with unilateral neglect and extinction show a profound lack of awareness of stimuli presented contralateral to their lesion. However, many processes of perception are intact and contralesional stimuli seem to reach a high level of representation,

Effects of pattern masks on the formation of perceptual grouping

open access: yesVision Research, 2017
Mechanisms underlying perceptual grouping serve to bind stimulus components that are contained within grouped patterns. In order to examine the time course of grouping development, grids of spatially isolated dots were followed by pattern masks across a range of SOA. Subjects indicated the predominant perceived grouping of the dot patterns.

Dichoptic masking and binocular rivalry share common perceptual dynamics [PDF]

open access: yes, 2007
Two of the strongest tools to manipulate visual awareness of potentially salient stimuli are binocular rivalry and dichoptic masking. Binocular rivalry is induced by presenting incompatible images to the two eyes over prolonged periods of time, leading ...

Visual Attention Guided Pixel-Wise Just Noticeable Difference Model

open access: yesIEEE Access, 2019
The just noticeable difference (JND) models in pixel domain are generally composed of luminance adaptation (LA) and contrast masking (CM), which takes edge masking (EM) and texture masking (TM) into consideration.

Comparison of Two Types of Composite-Opaquer Combinations Masking Ability for Tooth Discoloration without Clinically Visible Opacity [PDF]

open access: yesJournal of Dentistry
Background: A few studies have examined the masking ability of the combined application of opaquer and resin composites on tooth discoloration.Purpose: This study investigated the combined application of opaquer-composite to mask discolored backgrounds ...

Involvement of top-down networks in the perception of facial emotions: A magnetoencephalographic investigation

open access: yesNeuroImage, 2020
Conscious perception of the emotional valence of faces has been proposed to involve top-down and bottom-up information processing. Yet, the underlying neuronal mechanisms of these two processes and the implementation of their cooperation is still unclear.

Peeling Plaids Apart: Context Counteracts Cross-Orientation Contrast Masking

open access: yes, 2009
Background: Contrast discrimination for an image is usually harder if another image is superimposed on top. We asked whether such contrast masking may be enhanced or relieved depending on cues promoting integration of both images as a single pattern ...
