Similar findings with a rod-and-frame stimulus have also demonstrated that the orientation of a central target is either captured or repulsed by the frame, depending on its orientation (Beh, Wenderoth, & Purcell, 1971).
The central target was a man named Marcelo Valle Silveira Mello, who was detained by police in his house in Curitiba, the capital city of the southern Brazilian state of Paraná.
This was replaced by the target and, if present, the surround, both of which were presented until the participant made an untimed judgment about whether the central target was tilted left or right.
Participants viewed a 3D display and judged whether the central target was in front or behind the surrounding annulus.
A reference IMRS plan was designed to simultaneously treat the three targets, but only a single isocenter located at the center of the central target was used.
The central target was to eliminate the current structural deficit - that's the borrowing which is not for investment and not expected to go away naturally - with economic growth.
The central target was presented about fixation.
Observers judged whether the central target was offset above and to the left or below and to the right of an implicit line connecting the centroids of the two flankers (outer patches).
The central target was located in the centre of the screen, with flanking dots positioned 6DVA left and right of centre, matching the eccentricity of targets in the main experiment.
The density of the array (center-to-center spacing of the flankers and central target) was varied from 4.3° (most crowded) to 10.7° (least crowded) in four steps of 1.6°.
