Perceptions

We have unconscious assumptions how this world works when interpreting the information regarding:

• color: object in the shadow is lighter.
• object detection
• depth

The Gestalt psychologists proposed:

• proximity
• similarity
• closure
• good continuation
• Good form

Some experiments:

• Muller Lyer illusion
• Ponzo illusion

Attention

Stroop Effect: combine the color and word, the attention on the word distracts you.

Memory

• implicit vs. explicit
• semantics(facts) vs. episodic
• recall vs. recognition
• sensory vs short term vs long term.

Short term memory has limited storage, $7 +/- 2$, found by George Miller.

Encoding for long term memory:

• Depth of processing
• Mnemonics
• Understanding.

Basically add more context to the things.

Factors we have difficulties to retrieve memory:

• Decay
• Interference
• Change of cues

False Memories

• Expectations
• Leading questions
• Hypothesis
• Repressed memories, — still skeptical.
• Flashback memories, — might not be true even vivid.
