A Unified Theory of Psychophysical Laws in Auditory Intensity Perception

Frontiers in Psychology, 2020
Psychophysical laws quantitatively relate perceptual magnitude to stimulus intensity. While most people have accepted Stevens’s power function as the psychophysical law, few believe in Fechner’s original idea using just-noticeable-differences (jnd) as a ...

Perceptual Errors Support the Notion of Masking by Object Substitution [PDF]

Perception, 2019
Two experiments examined the effect of object substitution masking (OSM) on the perceptual errors in reporting the orientation of a target. In Experiment 1, a four-dot trailing mask was compared with a simultaneous-noise mask. In Experiment 2, the four-dot and noise masks were factorially varied. Responses were modelled using a mixture regression model

Training-induced recovery of low-level vision followed by mid-level perceptual improvements in developmental object and face agnosia [PDF]

, 2015
Long-term deprivation of normal visual inputs can cause perceptual impairments at various levels of visual function, from basic visual acuity deficits, through mid-level deficits as contour integration and motion coherence, to high-level face and object ...

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

, 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.

Dynamics of perceptual bi-stability for stereoscopic slant rivalry and a comparison with grating, house-face, and Necker-cube rivalry [PDF]

, 2005
A way to study conscious perception is to expose the visual system to an ambiguous stimulus that instigates bi-stable perception. This provides the opportunity to study neural underpinnings related to the percepts rather than to the stimulus.

Effects of pattern masks on the formation of perceptual grouping

Vision 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.

Perceptual masking of spondees by combinations of talkers [PDF]

The 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

Musical Mix Clarity Prediction Using Decomposition and Perceptual Masking Thresholds

Applied Sciences, 2021
Objective measurement of perceptually motivated music attributes has application in both target-driven mixing and mastering methodologies and music information retrieval. This work proposes a perceptual model of mix clarity which decomposes a mixed input

You Can Stand Under My Umbrella: Cognitive Load in Second-Language Reading

Behavioral Sciences
Second-language (L2) written processing has often been linked to cognitive disfluency, resembling fluency disruptions caused by perceptual challenges, such as visual degradation. This study used Virtual Reality to investigate whether cognitive disfluency

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

NeuroImage, 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.
