记忆—魔术时刻
从上述牌中默默选择一张并记住，不要告诉别人

记忆
记住你选择的牌了吗？
现在我会让你选择的这张牌消失！

什么是记忆?
• 记忆需要你在一定时间内保存信息 • 记忆几乎参与所有的认知过程 • 记忆
– 对所有的认知行为都很关键, 例如语言，问 题解决，决策等 – 具有相当的理论价值。 记忆是如何工作的？ 存在不同的记忆系统吗？什么影响了记忆效 果的好坏和提取效果的好坏？ – 具有实用价值（例如教学，错误记忆，魔术 记忆 “mega-memory”）。

操作性条件反射
• 后果决定行为

1950年之后
• 认知心理学的研究手段，信息加工的视 角 • 记忆的主要过程：编码，存储，提取 （encoding, storage, and retrieval） • 编码: 如何把物理的、感觉的输入转变为 可以输入记忆的适当表征 • 存储: 如何在记忆中保持编码的信息 • 提取: 如何获得记忆中存储的信息的有效 入口 14 • 这些过程互相影响，不是独立的
Probe
7 0 8 4 1 6 0 9 5 5 3 7 2 4 7 8
TONE
The tone is a signal to recall one of the digits. The last digit before the tone (8) occurs only once at an earlier point in the list.
This is called the “probe”.

– 初级记忆（primary
memory）包含了我们 当前觉知到的概念和想 法
– 次级记忆（secondary
memory）储存着那些 我们当下并不觉知，但 是当需要的时候可以提 取的想法
Recall
TONE
The subject’s task is to recall the digit following the probe. Between the digit, 4, and the tone, two things happen: (1) time passes, and (2) more digits are presented. 20

提取
Refers to the process by which information is initially recorded in a form usable to memory
The maintenance of material saved in the memory system

Recall
TONE
Time and digits are correlated (confounded). To separate them, Waugh & Norman used two rates of presentation: slow (1 digit per second) and fast (4 digits per second).
TONE
Which is more important in causing forgetting, time or the additional digits?
The decay principle implies time; the displacement principle implies digits.
