Memory “ We do not remember days, we remember moments. The richness of life lies in memories we have forgotten.” - Cesare Pavese
2
Memory Systems Explicit Implicit Intentional recollection
Conscious effort Hippocampus involved Ex: remembering vocabulary for a psych quiz Implicit Remembering things you didn’t intend to store Unconscious processes involved Unaffected by amnesia, age, or drugs Cerebellum involved Ex: What did you have for dinner last night? Ex: Motor skills
3
Memory Systems Declarative (Endel Tulving)- factual information handled by hippocampus & areas of the cortex Episodic- personal facts and experiences Like an autobiography Maybe unique to humans Ex: first day of school Semantic- general, factual knowledge Ex: knowing the state capitals Like an encyclopedia NonDeclarative/Pro-cedural- actions and skills (muscle memory) Little conscious awareness Ex: riding a bike Performance decreases if you think too much Doesn’t decline much Cerebellum and amygdala
4
Retrospective v. Prospective Memory
Remembering events from the past or previously learned info Ex: who won the Super Bowl last year? Remembering to perform actions in the future Ex: walk the dog
5
3 Key Processes of Memory
Encoding Storage Retrieval Encoding- forming a memory code Storage- maintaining encoded information over time Retrieval- recovering information from memory stores
6
Encoding Experiment Time! Levels of Processing Encoding Techniques
Structural Phonemic Semantic (deepest level) Encoding Techniques Elaboration Visual Imagery- concrete v. abstract words Dual Coding Theory- memory is enhanced by forming semantic and visual codes Self-referent encoding- deciding if info is personally relevant
7
Storage Information Processing Theory- incoming information passes through 2 temporary areas of storage (sensory & short-term) and then is transferred to long-term storage Sensory Short Term Long Term (working)
9
Sensory Memory Allows sensation to linger for a brief moment after stimulus is presented Less than a second Ex: afterimage Experiment with Trigrams!

Short-term memory (STM)
Limited capacity (7-9 items) Limited duration (up to 20 sec.) Rehearsal causes STM to last longer Interference EXPERIMENT! Chunking Serial-Position Effect (primacy/recency)

Long-Term Memory (LTM)
Unlimited capacity over long periods of time Flashbulb Memories- vivid & detailed recollections of momentous events in our life Schema (prototype)- mental categories about a particular object based on a particular experience Stored info is often organized around schemas Semantic Network- related concepts are joined closer together
