Memory
Levels of Memory
A) Sensory: Records information from the senses for only a few seconds
Encoding depends on attention
![Page 5: Memory Levels of Memory and How They Work. Memory Memory : Capacity to acquire, retain, and recall knowledge and skills](https://reader035.vdocuments.site/reader035/viewer/2022062304/56649ef15503460f94c0248a/html5/thumbnails/5.jpg)
Memory
Types of memory
B) Short-term memory: Holds information for up to 15 or 20 seconds.
Rehearsal helps information stay longer
Short term memory can store about 7 ungrouped items.

Memory

Types of Memory
C) Long-Term Memory:
Items that are important to you or have meaning are stored in long-term memory.
We can retain countless amounts of information, however recall might limit memory.

Memory
Long term memory is sorted into two categories:
Declarative (Facts)
Episodic
Semantics
Procedural (How-to)

Memory
Serial Position effect
Primacy effect: Rehearse more often, and therefore transfer to long-term memory
Recency effect: Still present in short-term memory, has not been ‘bumped-out’.
