Answer: A key difference between sensory memory and short-term memory is the duration of each type of memory. Sensory memory refers to the brief storage of sensory information, such as visual or auditory stimuli, for a very short period of time, typically lasting only a few seconds. For example, when you see a flash of light, the image may linger in your sensory memory for a split second before quickly fading away. In contrast, short-term memory, also known as working memory, refers to the temporary storage of information that is being actively processed and manipulated, such as remembering a phone number long enough to write it down. Short-term memory lasts longer than sensory memory, typically up to around 20-30 seconds, and has a limited capacity for the amount of information that can be held at one time.
