Encoding the processing of information into the memory system i.e., extracting meaning
Memory
Storage
the retention of encoded information over time
memory measure that assesses the amount of time saved when learning material a second time
Priming
activation, often unconsciously, of particular associations in memory
Working Memory
focuses more on the processing of briefly stored information
Memory
Short-Term Memory
activated memory that holds a few items briefly look up a phone number, then quickly dial before the information is forgotten
Encoding
Effortful Processing
requires attention and conscious effort
Encoding

Serial Position Effect--tendency to recall best the last items in a list
What Do We Encode?
Semantic Encoding
encoding of meaning including meaning of words
Learning some items may disrupt retrieval of other information
Proactive (forward acting) InterBiblioteka Baiduerence
disruptive effect of prior learning on recall of new information
Acoustic Encoding
encoding of sound especially sound of words
Visual Encoding
encoding of picture images

Encoding
Imagery
mental pictures a powerful aid to effortful processing, especially when combined with semantic encoding
Spacing Effect
distributed practice yields better longterm retention than massed practice
Encoding
Time in minutes taken to relearn list on day 2 20
Facts-general knowledge (“semantic memory”)
Personally experienced events (“episodic memory”)
Skills-motor and cognitive
Dispositionsclassical and operant conditioning effects
Organized information is more easily recalled

Short-Term Memory
Storage: Long-Term Memory Subsystems
Types of long-term memories
Explicit (declarative) With conscious recall
Implicit (nondeclarative) Without conscious recall
Ebbinghaus forgetting curve over 30 days-initially rapid, then levels off with time
30 Time in days since learning list
Forgetting
Forgetting can result from failure to retrieve information from long-term memory
Retrieval
process of getting information out of memory
Memory
Sensory Memory
the immediate, initial recording of sensory information in the memory system
Memory
persistence of learning over time via the storage and retrieval of information
Memory
You remembered what you learned in the last class, this is memory. Memory is very important for us With out memory, we can not know our parents, friends and so on. Our life will be terrible. Alzheimer's disease

Recall
measure of memory in which the person must retrieve information learned earlier as on a fill-in-the blank test
