Attentional eye selection modulates sensory eye dominance (2021)
Journal Article

Transparency perception often occurs when objects within the visual scene partially occlude each other or move at the same time, at different velocities across the same spatial region. Although transparent motion perception has been extensively studi... Read More about Criterion-free measurement of motion transparency perception at different speeds.
