Knowledge
In the Head
"Knowledge in the head is knowledge in the human memory system" (Norman, p. 81)
-
"Knowledge in the head is efficient: no search and interpretation of the environment is required" (Norman, p. 106).
In the World
"Because so much knowledge is available in the environment, it is surprising how little we need to learn" (Norman, p. 82).
Knowledge "how": procedural knowledge. Best taught by demonstration and learned through practice. Subconscious.
"Knowledge in the world acts as its own reminder. It can help us recover structures that we otherwise would forget" (Norman, p. 106).
Memory
STM: working memory of the just present (Norman, p. 92)
"To maximize the efficiency of working memory it is best to present different information over different modalities: sight, sound, touch (haptic), hearing, spatial location, and gestures" (Norman, p. 94).
-
"Knowledge in the head is actually knowledge in memory: internal knowledge" (Norman, p. 96). #
Memory for arbitrary/meaningful things #
Arbitrary: rote learning. "The bane of modern existence" (Norman, p. 97).

Reaction: I didn't like this chapter as much as I liked the others. This one seemed to jump around a lot and lack clear/predictable headings. I think the terms "Knowledge in the head" and "Knowledge in the world" are irritating. Knowledge doesn't exist "in the world," it exists in our interpretations of the world, and interpretations are within the head. So technically all knowledge is "in the head," which combined with the awkwardness of the phrase, is irritating. Other than that I enjoyed the sections on mapping and learning about how little precise knowledge matters for everyday life. I certainly would have gotten the penny question wrong! I picked the correct combination of symbols/words but the head I picked was facing the wrong way.
