Short-term memory is also known as working memory, and it is where information is temporarily stored and processed for a brief period. It has limited capacity and duration and is capable of holding information for only a few seconds to a minute. Shelly's ability to remember the names of three new class members for only a minute or two suggests that this information was stored in her short-term memory. Echoic memory refers to the sensory memory for sounds, iconic memory refers to the sensory memory for visual stimuli, and implicit memory refers to the unconscious, long-term memory for skills and habits.
