Memory

Processing storage and retrieval of information acquired through learning

Encoding

The process of converting information into a usable form so that it can be represented and stored in memory

Storage

The retention of information in memory over time

Retrieval

The process of locating and recovering the stored information from memory so that we are consciously aware of it

Models of human memory

Atkinson and shifferin's multi store model


Baddeley and hitch's model of working memory


Craik and Lockhart's levels of processing framework

AS, BH, CL.

Atkinson and shiffrin's multi store model of memory

Represents memory as three separate components called the sensory register, the short term store and the long term store

Serial position effect

Finding that free recall is better for items at the end and beginning of the list than for items in the middle of the list


Chunking

Is the grouping of separate bits of information into a larger single unit, or chunk of information.

Baddeley and hitch's model of working memory

The structure and function of working memory in terms of four components called the phonological loop, visuo-spatual sketchpad, episodic buffer and central executive

Phonological loop

Temporarily stores a limited amount of verbal speech-like information for a brief time.

Visuo-spatial sketchpad

Temporarily stores a limited amount of visual and spatial information for a brief time.

The central executive

Controls attention, integrates information from the phonological loop and visuo-spatial sketchpad, as well as information retrieved from LTM

The episodic buffer

A sub-system of working memory that enables the different components of working memory memory to interact with LTM

Craik and Lockhart's levels of processing framework

Processes that the level, or 'depth'at which we process information during learning determines how well it is stored in LTM


Long term memory

The memory system that stores vast amounts of information for a very long time,.possibly permanently

Declarative memory

Facts and events.. knowing what

Procedural memory

Actions and skills... Knowing how

Semantic memory

Facts

Episodic memory

Events

Semantic network theory

Information in LTM is organised systematically in the form of overlapping networks of forgetting that are interconnected and interrelated by meaningful links.


Spreading activation

Activating one node during retrieval from a semantic network increases the likelihood that associated nodes become activated

Consolidation theory

Structural changes occur in the brain when something new is being learned, and immediately after learning.


Reconsolidation

after a memory is activated and retrieved from LTM, it needs to be consolidated again in order to be stored back in LTM

Brain trauma

An umbrella term that refers to ang brain damage that impairs, or interferes with, the normal functioning of the brain, either temporarily or permanently.

Neurodegenerative disease

A disorder charactised by the progressive decline in the structure, activity or function of brain tissue.

Amnesia

The loss of memory, either partial or complete, tempory or permanent.

Anterograde amnesia

Can't make new memories

Korsakoffs syndrome

A Neurodegenerative disease involving severe memory disorders associated with brain damage

Confabulation

Filling in gabs in memory with plausible but untrue stories rather than admitting memory loss.

Retrograde amnesia

Can't remember either some or all LTM but can encode new memories

Dementia

An umbrella term used to describe a variety of symptoms of a large group of Neurodegenerative diseases and other disorders that cause a progressive decline in mental functioning, behaviour and the ability to preform everyday tasks

Alzheimers disease

A type of disease charactised by the gradual widespread degeneration of brain neurons, causing memory loss, a decline in cognitive and social skills and personality changes.

The forgetting curve

The pattern of forgetting that occurs over time.

Ebbinghaus

First person to scientifically study the forgetting curve

Retrieval cue

Any stimulus that assists the process of locating and recovering information stored in memory

Retrieval failure theory

Sometimes forget because we lack of fail to use the right cues to retrieve information stored in LTM


TOTT

A state or feeling that occurs when you are aware of knowing something, and are confident you will eventually remember it, but you are unable to retrieve it.

Retroactive interference

When new information interferes with the ability to remember old information

Proactive interference

When old information interferes with the ability to learn new information

Motivated forgetting

Forgetting that arises from a strong motive of desire to forget.

Repression

Unconsciously blocking a memory of an event or experience from entering the conscious awareness

Supression

Being motivated forget an event or experience by making a deliberate conscious effort to keep it out of consciousness awareness


Decay theory

Occurs because the neural Representation of a memory fades through disuse as time passes


Narrative chaining

Linking otherwise unrelated items to one another, to form a meaningful sequence of story
