The 3 Processes of Memory Encoding Storage Retrieval 1 2 3

3 Processes of Memory Encoding Storage Encoding: The transforming of information so the nervous system can process it. Retrieval Basically using your senses● You use acoustic codes by saying something out loud to yourself, over and over ● Visual codes are used when you make mental pictures ● Semantic codes are used when you try and make some kind of meaning: remember the word “face” rather than each individual letter

3 Processes of Memory Encoding Storage: The process by which information is maintained over a period of time. Retrieval ● Dependent upon how much effort was put into encoding the information.

3 Processes of Memory Encoding Storage Retrieval: The process of obtaining information that has been stored in memory.

The Three Stages of Memory Sensory Memory Short-term Memory Long-term Memory 1 2 3

Three Stages of Memory Sensory Memory Short-term Memory Sensory memory Very brief memory storage immediately following initial stimulation of a receptor. • holds info for a fraction of a second • why you don’t notice gaps in motion pic Long-term Memory

Three Stages of Memory Sensory Memory Short-term memory Memory that is limited in capacity to about 7 items, and in duration by the subject’s active rehearsal. • holds info for about 30 seconds Long-term Memory “Magic # 7”

Now… write down as many as you can remember -Let’s make a list on the board -How’d ya do? Let’s see…. . .

Short-Term Memory • Maintenance rehearsal – A system for remembering that involves repeating information to oneself without attempting to find meaning in it. • Chunking – The process of grouping items to them easier to remember. make

Short-Term Memory • Primacy-recency effect – We are better able to recall information presented at the beginning (primacy) and end (recency) of a list. • Working memory – Another name for short-term memory.

Three Stages of Memory Sensory Memory Short-term Memory Long-term memory The storage of information over extended periods of time. • holds an unlimited amount of info

Sensory Memory • Iconic Memory – Visual sensory memory – Holds visual information for up to a second • Echoic Memory – Auditory sensory memory – Holds auditory information for 1 - 2 seconds

Types of Long-Term Memory: Semantic memory Episodic memory Declarative memory Procedural memory

Long-Term Memory • Semantic memory – Knowledge of language, including its rules, words, and meanings. • Episodic memory – Memory of one’s life, including time of occurrence.

Long-Term Memory • Declarative memory – Memory of knowledge that can be called forth consciously as needed. • Procedural memory – Memory of learned skills that does not require conscious recollection.
