Q

Control processes (Atkin)

A

in the Atkinson–Shiffrin multi- store model, an activity that is consciously performed to assist the memory process, such as attention and maintenance rehearsal

Q

Sensory Memory

A

Entry point of memory where new information is stored for a very brief period. Info received by each sensory system is retained as an exact copy of its original “RAW” sensory form.

Q

Short term Memory (STM)

A
  • limited capacity 7+-2 items
  • limited duration: 18-25 seconds
  • contains everything that you are consciously aware of at any moment and paying attention to.

Q

Elaborative rehearsal

A
  • linking new information to old information in LTM
  • meaningfully linking together two or more pieces of new info
  • linking new info to real life (everyday examples)

Q

Maintenance rehearsal

A

Involves repeating the information being remembered over and over again so that it can be retained in STM or Working memory.

Q

Working memory

A

Emphasises the part of memory where information is temporarily held and actively “worked on” as we undertake our everyday tasks.

Q

Serial position effect

A

Tendency to recall items from the beginning and end of a list while losing items from the middle of the list.

16
Q

Serial position effect, why are items in the BEGINNING recalled?

A

Because they are rehearsed and transferred to LTM - results in PRIMACY EFFECT.

17
Q

Primacy effect

A

Describes superior recall of items in he beginning of a list.

18
Q

Serial position effect: why are items from the end of the list recalled?

A

Because they are still “live” in STM, this results in RECENCY effect.

19
Q

RECENCY effect

A

Describes superior recall of items at the end of a list.

20
Q

Baddest and Hitch’s model of working memory

A

Describes the structure and function of working memory and it’s 3 sub-systems.

21
Q

Name the 3 sub-systems of working memory.

A
  1. Phonological loop
  2. Visuo-spatial sketchpad
  3. Central executive
22
Q

Phonological loop

A

Verbal working memory - “inner voice”, stores a limited amount of sounds received echoic memory or LTM.

23
Q

Visuo-special sketchpad

A

Visual and spatial working memory - “inner eye” refers to our awareness of objects around at any one time. Anything you can see or visualise.

24
Q

Central executive

A

Makes executive decisions about how we use this information while it is held in Working memory. Controls attention, integrates information and coordinates the flow of information between the working memory system and long- term memory

25
Q

Episodic buffer

A

Sub-system functions as a ‘slave’ of the central executive:

  • finds relevant information in LTM and brings it into WMD
  • links this info to new info it receives from the phonological loop and the Visuo-spatial sketchpad.
  • makes this newly integrated information available to the central executive.
26
Q

Craik and Lockhart’s theory

A

Levels of processing framework. Proposes that the level, or ‘depth’, at which we process information during learning determines how well it is stored in LTM.

27
Q

C&L Theory continued

A

The deeper the processing, the mor successfully the information is encoded and stored.

  • very shallow processing: (maintenance rehearsal) it will be less efficiently stored.
  • shallow, intermediate, deep processing
28
Q

Shallow processing (maintenance rehearsal)

A

Type: structural - physical appearance of info.

- less likely remembered, poorly encoded and stored.

29
Q

Intermediate processing

A

Type: Phonemic - includes sounds as well as image.

- better storage and retrieval

30
Q

Deep processing (elaborative rehearsal)

A

Type: Semantic - according to meaningfulness.

- produces long lasting memory traces.

31
Q

Long term memory

A

Relatively permanent, unlimited store house of info that has been drawn and consolidated from short-term (working) memory.

32
Q

Procedural memory

A

LTM of how how to perform certain tasks.

33
Q

Declarative memory

A

Memories can only be demonstrated if stated out loud. Facts and events.

34
Q

Semantic memory (declarative)

A

LTM of factual info.

35
Q

Episodic memory (declarative)

A

LTM of events you have witnesses or have been involved in.

36
Q

Explicit Memory

A

(Declarative memory) - information has to be consciously retrieved and stated.

37
Q

Implicit memory

A

(Procedural memory) does not involve conscious or intentional retrieved.

38
Q

Semantic Network theory

A

Proposes that information
