Perceptual Organization and Gestalt Principles (6A) Practice Test

In an eye-tracking study, participants view a display where two sets of dots are intermingled: one set consists of light-gray dots and the other set consists of dark-gray dots. The dots are evenly spaced, and there is no clear spatial clustering. Participants’ initial fixations tend to alternate between regions dominated by the same shade, and they report perceiving two overlapping groups. Based on the Gestalt principle of similarity, which conclusion is most supported?

In a perception task emphasizing Gestalt continuity, participants view a curved line partially occluded by a rectangle in the center of the screen. They typically report a single continuous curve “behind” the rectangle rather than two separate curves ending at the rectangle’s edges. Which report best reflects continuity?
