The notion that strategic processes affect performance is indicated by the overwhelmingly large proportion (89%) of participants who reported adopting a strategy based on either apparent motion
or flash cues, or both, on the line IT task.
A research program was initiated to identify the factors that are critical for the accurate perception of apparent motion
in animated mimic displays (Bennett, 1993; Bennett & Madigan, 1994; Bennett & Nagy, 1996).
* The most important piece of equipment that astrophotographers need to move into the exciting field of deep-sky imaging is a tracking equatorial mount that allows their cameras and telescopes to follow the sky's apparent motion
during long exposures.
Mackenzie and Bingham (1985) reported that apparent motion
influenced the association between IT and Wechsler IQ.
One sees, fixed in space, a horizontal array of lights blinking on and off in sequence (from right to left) giving an impression of apparent motion
, or phi, with the entire array being displaced to the right, in the direction of the attendant saccade.
During some versions of IT subjects report using post-stimulus apparent motion
cues to guide their discriminations (Egan, 1986; Nettelbeck, 1982; see Fig.
As a central case-study, this proposal investigates human visual apparent motion
perception in V1/2/3 and V5/MT+.
The pair's motion through space and nearness to us give it an extraordinarily rapid apparent motion
across the backdrop of distant stars.
The Sun's daily apparent motion
of roughly a degree eastwards along the ecliptic (really a consequence of Earth's orbital motion, of course) carries it to increasing northerly declinations on the celestial sphere during this interval.
During its 4-year mission, Hipparcos measured parallax--the apparent motion
of stars caused by Earth's changing vantage point as it orbits the sun.
RDK form detection involves the processing of apparent motion
. Succinctly defined by Petersik (1989), "Apparent motion
is the experience of motion that occurs when at least two spatially separated stimuli are alternately presented to an observer over time" (p.
In addition, the D810A has inherited a number of functions from the D810 that are convenient for astrophotography, including the ability to enlarge the view through the lens displayed in the camera monitor during live view up to approximately 23x to facilitate accurate focusing, an electronic front-curtain shutter that thoroughly suppresses mechanical shake, and a continuous shooting function with no limit on the number of shots possible for creating beautiful star trails (apparent motion
of stars around the Earth).
