@Augmenting Long-term Memory

Solomon Shereshevsky 以超级记忆力闻名

  • [[Ted Nelson]] [[Project Xanadu]] hypertext, and, indirectly

  • Tim Berners-Lee world wide web

Anki makes memory a choice , rather than a haphazard event , to be left to chance.

  • I describe some useful patterns of Anki use , and anti-patterns to avoid.
    But, as we shall see, there are already powerful ideas about personal memory systems based solely on the structuring and presentation of information.
  • 从信息组织和展示的角度入手。

[[@Appendix 1: analysis of Anki study time]] Here’s a ballpark analysis of the effort required to study an Anki card for recall over 20 years

@Part II: Personal Memory Systems More Broadly

两个问题

  • how important is memory as a cognitive skill

  • what is the role of [[cognitive science]] in building personal memory systems ?
    How important is long-term memory, anyway?

  • “rote memory” 比理解更低级?

  • memory is the foundation of our cognition

    • My somewhat pious belief was that if people focused more on remembering the basics , and worried less about the “difficult” high-level issues , they’d find the high-level issues took care of themselves.

    • I now believe memory of the basics is often the single largest barrier to understanding

    • 熟悉新领域基础知识有助于理解

    • Adriaan de Groot and [[Herbert A. Simon]] studying how people acquire expertise, focusing particularly on chess

      • They found that world-class chess experts saw the board differently to beginners. 大师和新手看到的棋盘不一样

        • A beginner would see “a pawn here, a rook there”, and so on, a series of individual pieces.
        • Masters, by contrast, saw much more elaborate “ chunks ”: combinations of pieces that they recognized as a unit, and were able to reason about at a higher level of abstraction than the individual pieces.
        • 有关国际象棋大师和新手的区别:专家拥有更加复杂的 chunks
      • Simon estimated chess masters learn between 25,000 and 100,000 of these chunks during their training, and that learning the chunks was a key element in becoming a first-rate chess player. Such players really see chess positions very differently from beginners.

      • [[@刻意练习]]里面也要提到过

      • George Miller 论文 The Magical Number Seven, Plus or Minus Two,提出 chunks was effectively the  basic unit of working memory

  • distributed practice meaning :-> practice which is distributed in time

    • Hermann Ebbinghaus

    • Ebbinghaus forgetting curve 遗忘曲线

On the role of cognitive science in the design of systems to augment cognition

  • they show emphatically that distributed practice outperforms massed practice

  • 反例子:某些技能在一定时间后会增强

    • we learn to swim during the winter and to skate during the summer.

    • an 1895 study of Axel Oehrn

  • memory is complicated , we don’t understand many of the big picture questions well, and we should be careful before we put too much faith in any given model.
    + memory is complicated 还需要时间去理解相关的内容

  • 如何在理论不完善的背景下,开始设计系统?
