between shapes differing in location and orientation: A window technique for estimating path curvature.
The priming paradigm empolyed in the present study can be used to investigate the process of mental transformation in a static image as well as apparent motion
in a dynamic image.
B-7 "Making a sun Clock" (using a sundial), and B-8 "Plotting the Apparent Motion
of the sun" (using a clear plastic hemisphere).
Hence, rather than attributing the use of systematic strategies, such as those based on apparent motion
cues, entirely to the failure of the backward masking procedure, it is possible that there is something inherent in the two-line IT stimulus itself that may facilitate movement cues.
The perceptual characteristics of adjacent graphical elements in a display are translated (i.e., moved) so that they produce apparent motion
. This process is represented graphically by the two pairs of shaded bars in Figure 2a.
Latitude (position north-south) could be read by observing the apparent motion
of the sun.
Struve 2576's stars have the same proper motion (apparent motion
on the celestial sphere) and distance (69 light-years) as 17 Cygni; therefore, they may have a common origin.
The same effect can be used to calculate the distance to stars, by measuring the apparent motion
of a nearby star compared to more distant background stars.
Our 24-hour day is based upon this apparent motion
of the Sun, because the planet upon which we stand rotates on its axis every 24 hours.
As the object approached the Earth, its apparent motion
accelerated as it brightened to reach almost 13th magnitude before it started to enter the Earth's penumbra about 01:17 UT.
It turns at the same rate but in the opposite direction of Earth's rotation, thus effectively cancelling the sky's apparent motion
for any telescope mounted on it.
This lack of apparent motion
makes them ideal celestial landmarks for anchoring a grid system, similar to earthly latitude and longitude, used to mark the positions of celestial objects.
The cell filters out images of objects approaching its compound eye from other visual stimuli such as the apparent motion
caused by eye movements.
The potential benefits of reducing apparent motion
strategies in the IT paradigm have been discussed by Chaiken and Young (1993) who suggest that IT could become an important tool for assessing cognitive performance independently of motor involvement.
The graphical features responsible for more effective decoding (i.e., those producing effective apparent motion
) were identified; the findings have been summarized in a set of design guidelines.
