What is the primary function of sensory memory?

• A. To process and store material for long-term recall
• B. To hold sensory information for a brief moment
• C. To facilitate emotional association with memories
• D. To encode complex visual images

Answer: (B)

The primary function of sensory memory is to hold sensory information for a brief moment. This type of memory acts as a very short-term storage system that captures and retains sensory impressions from the environment, such as sights, sounds, and smells. It allows for the initial processing of incoming stimuli so that they can be briefly maintained in awareness. For example, if you see something out of the corner of your eye, sensory memory provides a quick recall that helps you to identify or engage with that stimulus before it fades away. Unlike long-term memory, which is responsible for storing information for extended periods, sensory memory operates on a much faster timescale and is crucial for the continuity of perception. This brief retention is essential because it enables individuals to perceive and respond to stimuli in a coherent way. Understanding sensory memory is fundamental to grasping how we initially interact with and interpret the world around us.
