Review the textbook notes of memory
What is memory?
❖ Encode Info, Store Info, Retrieve Info
❖ Think of memory as multiple memory systems
o Long term memory is an example of a type of memory system
▪ Episodic memory – only have to do it once, your own personal
memory of something that occurred
• Ex: I remember my trip to France last year
▪ Semantic memory – facts, general world knowledge
• Ex: the president of BU is Bob Brown. You don’t know
when you learned this, you just know that you do know this.
▪ Non-Declarative memory & Procedural memory – skill learning,
you don’t need conscious awareness
• Ex: riding a bike or writing on a keyboard
▪ Non-declarative = implicit memory, you don’t need conscious
awareness
▪ Declarative = explicit memory, you can verbally describe it and
tell someone about it, you have explicit knowledge
• Traditionally what we use, but there are so many
weaknesses in this model
