Syllabus: How Do We Remember—and Why Do We Forget?
Build a provisional map of memory from Squire's taxonomy, attaching an observation to each distinction. Keep the task, the claimed process, and the proposed neural system separate.
A question to consider. How could the same word-completion task provide evidence about either deliberate recollection or priming, depending on its instructions?
Why this reading
Remembering a meeting, knowing a fact, and becoming more skillful need not depend on the same processes. Squire connects distinctions among forms of memory to evidence from human amnesia, experimental tasks, and animal research. The paper makes classification an explanatory problem rather than a vocabulary exercise.
Before you read
Episodic memory concerns events experienced in a particular context; semantic memory concerns knowledge. Declarative memory encompasses facts and events. Nondeclarative memory is an umbrella for several forms of learning expressed through performance, including skills and priming. A dissociation is a difference in how abilities respond to a manipulation or impairment; it needs interpretation, not just a label.
Read for
- For each major division in the taxonomy, identify the comparison that supports it and what is being measured.
- Notice how instructions can change whether a word-completion task elicits deliberate recollection or priming.
- Compare examples of parallel operation and competition among systems with the idea of wholly isolated memory stores.
Consider afterwards
- Someone improves at a task without recalling previous practice. What additional comparison would help distinguish a separate learning process from an easier test of the same retained information?
Editorial context
This 2004 minireview presents a biologically grounded multiple-systems account and argues against competing views. It is a useful framework, not a complete contemporary map of memory. Tasks can recruit multiple processes, and distinctions among conscious experience, task performance, and neural organization do not automatically coincide. The mirror-drawing work discussed here followed the original 1957 report on H.M.
