The present study examined how a frame of reference was affected by velocity. This
question was examined with respect to a system consisting of two points: one moved …

In visual perception complex movements are usually split up into components—eg, in such a
way that a moving reference system is applied, to which partial movements can be related …

A reference frame is required to specify how motion is perceived. For example, the motion of
part of an object is usually perceived relative to the motion of the object itself. Johansson …

The threshold of perception of movement in the absence of an external frame of reference is
studied, for conditions (a) constant distance moved,(b) constant duration of movement. It was …

We investigated how the visual system selects a reference frame for the perception of
motion. Two concentric arcs underwent circular motion around the center of the display …

Investigated whether pursuit eye movements affect motion perception, particularly target
velocity perception, under the following stimulus conditions in 2 experiments:(1) laterally …

We used a reaction-time paradigm to examine the extent to which motion detection depends
on relative motion. In the absence of relative motion, the responses could be described by a …

Lighted points that moved as if located on the rim of a rolling wheel were displayed to
subjects whose task was to describe the pattern they perceived. The perceived patterns …

Neurophysiological and neuroimaging work has uncovered modulatory influence of long-
range lateral connections from outside of the classical receptive field on neuronal and …

Four experiments are reported that investigated the role of the perceived coplanarity of a
moving target with respect to a frame of reference in the third dimension on the perceived …
