1. Intro
Cognitive psychology, how we perceive the world, how attention works, how we store our memory
2. Perception and Attention
Perception is a hard problem
How we recognize the object? Still not well studied; Machines are getting better and better
See the perception system into math style, images are just number array
Different level
- Brightness
The brain would compensate the scene automatic
- Objects
Proximity, we would take the natural form into count.
Continuation, tendency to continue
Good form
- Depth
Geometry, size, intersect
None of them is conscious,
Attention, three stage memory
- Sensory memory
- Short term memory
- Long term memory
How from 1$\to$2? Attention
- Some are effortless
- Some need more attention
- Some are can’t stop (read, hear)
3. Memory
Implicit and Explicit
Long term memory is like unlimited, people never reach the limit
Short term memory is quite limit
- The basic unit in short term memory is chunks
Feed something INTO brain
Learning? How to get things into LTM?
- Think deeper, add more sense, add more connection
- By image, mnemonic
Get something OUT of brain
- Retrieval curs
- Compatibility principle
- Searching strategies
Why sometimes we FORGET?
- Decay
- Interference
- Change of cues
What is learning? Create new memory
Why sometimes our memory is WRONG?
- Expectation
- Leading questions
- Hypnosis
- Repressed memories
- Flashbulb memories (vivid, important)
4. Reflection
我们是如何认识这个世界的？大脑信息的输入
- 视觉系统和注意力
记忆
- 我们如何记住？活动、短期、长期
- 我们如何回忆？刺激、类似、搜索
- 我们如何遗忘？消退、错误、改变
记忆并不可靠
