Check your understanding of the various types of memory discussed in this chapter by matching the definitions below with the following: (a) sensory memory, (b) short-term memory, (c) long-term memory, (d) declarative memory, (e) nondeclarative memory, (f) episodic memory, (g) semantic memory, (h) retrospective memory, and (i) prospective memory. The answers can be found in Appendix A. A limited-capacity store that can maintain unrehearsed information for about 20 seconds.

The given definition is "A limited-capacity store that can maintain unrehearsed information for about 20 seconds."

Review the different types of memory: (a) Sensory memory: Memory that holds sensory information for a very brief period of time, usually less than a second. (b) Short-term memory: A limited-capacity memory system that can store information for brief periods of time, typically around 20 seconds without rehearsal. (c) Long-term memory: A memory system that can store vast amounts of information for extended periods of time, potentially a lifetime. (d) Declarative memory: Memory that can be consciously accessed and described, including facts and personal experiences. (e) Nondeclarative memory: Memory that cannot be consciously accessed but can influence behavior, such as skills and habits. (f) Episodic memory: Memory for specific events and experiences that can be consciously recalled. (g) Semantic memory: Memory for general world knowledge, facts, and concepts that can be consciously recalled. (h) Retrospective memory: Memory for past events, knowledge, or skills. (i) Prospective memory: Memory for future intentions and tasks to be performed.

The given definition matches with (b) Short-term memory because it is a limited-capacity store that can maintain unrehearsed information for about 20 seconds.
