Working Memory

the function of memory

to encode, store and retrieve relevant information that supports adaptive behavior

working memory

in the moment access to goal-relevant information

central executive

→ phonological loop

→ visuo-spatial sketchpad

long-term memory

long term storage of lots of potentially relevant information

implicit

explicit

→ semantic

→ episodic

digit span

the largest number of items a person can reliably recall

Baddeley and Hitch model of working memory

a theoretical framework that describes working memory as having multiple components, including the central executive, phonological loop, and visuo-spatial sketchpad, each serving distinct functions in processing and manipulating information.

episodic buffer

integrates multi-modal information into episodic representations

phonological loop

stores and rehearses verbal and acoustic information

visuo-spatial sketchpad

stores and manipulates visual and spatial information

central executive

primary system for controlling attention and thinking

prefrontal cortex

-selecting relevant information

-inhibiting irrelevant information

-manipulating representations

-sequencing operations
