The impression tends to conform to the object as it is or is assumed to be, rather. Responses that simply parrot or repeat the terms from the question will not score. perceptual constancy, also called object constancy, or constancy phenomenon, the tendency of animals and humans to see familiar objects as having standard shape, size, colour, or location regardless of changes in the angle of perspective, distance, or lighting. ![]() Artists use these cues to help portray depth in their work and create a more realistic creation. ![]() There are many types of cues for example relative size, interposition, aerial perspective, linear perspective, texture gradient, and motion parallax. Rubric examples provided for each point are not to be considered exhaustive. Monocular Cues are used to help perceive depth by only using one eye. The last two links in the "Illustrations and Definitions" column below are concerned with the quantitative specification of parallax magnitude and the size of head movement to be used in the demonstrations. definition is not considered a direct contradiction and should score the point. (The apparent triangular surface demonstration is not included, because the density of the random dots is too low to simulate a surface that is discriminable from our sine wave surface.) Figures 1 and 2 that appear in the paper (and Figure 3 that appears in the "Definition of Motion Parallax Magnitude" link) are made available for instructors who want to use them in a lecture. ![]() To download the demonstrations Right Click (PC Users) or hold down the Option key on your keyboard and Click (Mac Users) on the links below. To download a free copy click on the QuickTime link below. We used a random-dot stimulus (Rogers & Graham, 1979) that ap- pears (to adult observers) as a 3-D corrugated surface undulating in depth along the vertical. To view the demonstrations you must have QuickTime installed on your computer.
