Abstract Information about a moving object is usually poor at each retinotopic location
because photoreceptor activation is short, noisy, and affected by shadows, reflections of …

Our perception of the world is governed by a combination of bottom-up sensory and top-
down cognitive processes. This often begs the question whether a perceptual phenomenon …

The perception of motion not only depends on the detection of motion signals but also on
choosing and applying reference-frames according to which motion is interpreted. Here we …

Unconscious visual stimuli can affect conscious perception: For example, an invisible prime
can affect responses to a subsequent target. The invisible interpretation of an ambiguous …

The motion of parts of an object is usually perceived relative to the object, ie,

Reference-frames, or coordinate systems, are used to express properties and relationships
of objects in the environment. While the use of reference-frames is well understood in …

The spatial representation of a visual scene in the early visual system is well known. The
optics of the eye map the three-dimensional environment onto two-dimensional images on …
