Which of the following is not used as a depth cue by the visual system? 1 pointa. sizeb. priming c. interposition d. distance

Breakdown of the Problem

1. Identify the options provided in the question that relate to depth cues.
2. Understand the definitions of depth cues and their roles in visual perception.

Relevant Concepts

1. Depth Cues: These are visual indicators that inform us about the distance of objects from the observer.
   • Examples include size, interposition, and distance, which are commonly used by the visual system to perceive depth.
   • Priming, however, does not directly contribute to depth perception but is related to cognitive processes.

Analysis and Detail

1. Size - Objects that are farther away appear smaller. This size constancy is a primary depth cue.
2. Interposition - When one object overlaps another, the overlapping object is perceived as closer, which is another effective depth cue.
3. Distance - Involves various cues, including linear perspective and texture gradients, which help indicate how far away objects are.
4. Priming - Refers to the cognitive process of exposure to certain stimuli influencing response to subsequent stimuli. It does not have a direct role in visual depth perception.

Verify and Summarize

• Of the options provided, size, interposition, and distance are all depth cues used by the visual system.
• Priming does not serve as a depth cue in visual perception.

Final Answer

The option that is not used as a depth cue by the visual system is b. priming.
