Self-Supervised Video Representation Learning with Motion-Contrastive Perception [PDF]
arXiv, 2022 Visual-only self-supervised learning has achieved significant improvement in video representation learning. Existing related methods encourage models to learn video representations by utilizing contrastive learning or designing specific pretext tasks.

Motion Perception and Personality III
Nordisk Psykologi, 1955 Experiments in the field of motion perception had indicated that there were good reasons for assuming a correlation between an analytical or isolating attitude in perception and a tendency to social isolation. The hypothesis advanced was: Those Ss who obtain extremely high scores in the velocity synthesis test, will be characterized, in the description

The perception of color from motion [PDF]
Perception & Psychophysics, 1995 We introduce and explore a color phenomenon which requires the prior perception of motion to produce a spread of color over a region defined by motion. We call this motion-induced spread of color dynamic color spreading. The perception of dynamic color spreading is yoked to the perception of apparent motion: As the ratings of perceived motion increase,

Amygdala Neurodegeneration: A Key Driver of Visual Dysfunction in Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Visual disability in Parkinson's disease (PD) is not fully explained by retinal neurodegeneration. We aimed to delineate the brain substrate of visual dysfunction in PD and its association with retinal thickness. Methods Forty‐two PD patients and 29 controls underwent 3‐Tesla MRI, retinal spectral‐domain optical coherence tomography,

Saccadic Suppression of Displacement Does Not Reflect a Saccade-Specific Bias to Assume Stability
Vision, 2019 Across saccades, small displacements of a visual target are harder to detect and their directions more difficult to discriminate than during steady fixation.

Neural coincidence detection strategies during perception of multi-pitch musical tones [PDF]
arXiv, 2020 Multi-pitch perception is investigated in a listening test using 30 recordings of musical sounds with two tones played simultaneously, except for two gong sounds with inharmonic overtone spectrum, judging roughness and separateness as the ability to tell the two tones in each recording apart.

On the role of Lip Articulation in Visual Speech Perception [PDF]
arXiv, 2022 Generating realistic lip motion from audio to simulate speech production is critical for driving natural character animation. Previous research has shown that traditional metrics used to optimize and assess models for generating lip motion from speech are not a good indicator of subjective opinion of animation quality.

Dyslexia and the assessment of visual attention [PDF]
, 2011 Visual stream segregation has been proposed as a method to measure visual attention in dyslexia. Another task proposed to do this is the line-motion illusion. Both tasks, it is observed, can be carried out with spatially distributed stimuli.

The efficiency of biological motion perception [PDF]
Journal of Vision, 2005 Humans can readily perceive biological motion from point-light (PL) animations, which create an image of a moving human figure by tracing the trajectories of a small number of light points affixed to a moving human body. We have applied ideal observer analysis to a standard biological motion discrimination task involving either full-figure or PL ...

Combination Therapy With Vigabatrin and Prednisolone Versus Vigabatrin Alone for Infantile Spasms
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective The study evaluated the effectiveness of combination therapy with vigabatrin and prednisolone versus vigabatrin alone for treating infantile epileptic spasms syndrome (IESS). Methods This single‐center, single‐blind, randomized trial enrolled infants aged 2–14 months with new‐onset IESS, randomly assigned them (1:1) to receive either
