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 …

Motion is often perceived according to non-retinotopic reference-frames (eg, Duncker's
wheel; biological motion); however, how reference-frames are selected remains to be …

The retinotopic projection of stimulus motion depends both on the motion of the stimulus and
the movements of the observer. In this study, we aimed to quantify the contributions of …

Random dot kinematograms (RDKs) have been used to study motion perception for
decades, but almost all studies involve a binary choice (eg, leftward vs. rightward). By …

The discriminability of motion direction is asymmetric, with some motion directions that are
better discriminated than others. For example, discrimination of directions near the cardinal …

Thus far, it has been pointed out that motion representation is completed in motion trajectory,
and that motion representation interferes with a single physical input at a specific time and …

The motion of a 1D image feature, such as a line, seen through a small aperture, or the small
receptive field of a neural motion sensor, is underconstrained, and it is not possible to derive …

We investigated the perceived position of visual targets in apparent motion. A disc moved
horizontally through three positions from− 10 to+ 10 in the far periphery (20 above fixation) …

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 …

Motion direction and luminance contrast are two central features in the representation of
visual motion in humans. In five psychophysical experiments, we showed that these two …
