Which principle asserts that objects and their context are mutually exclusive in depth discernment?

• A. Vision is selective
• B. Fixation solves a problem
• C. Discernment in depth
• D. Shapes are concepts

Answer: (C)

This question tests how depth is discerned in vision—the ability to separate an object from its background to judge how far away it is. Discernment in depth describes the way the visual system uses depth cues to isolate the figure from its context, so the object’s distance can be perceived clearly independent of surrounding surroundings. In practice, cues such as occlusion, relative size, shading, and perspective help determine that the object sits at a different depth level than the background, and the context is interpreted in a way that supports that depth judgment without confusing the object with its environment. This separation of the object’s depth information from the surrounding scene is what the principle captures. Other options touch on general aspects of perception or problem-solving but don’t address how depth judgments are made by distinguishing an object from its context, which is the essence of discernment in depth.
