Q

What did the Brown/Peterson and Peterson technique show about short term memory?

A

Short term memory is fragile, stored in seconds

inspired further study and increased support for cognitive approach

Q

what is the primacy effect and what is the assumption behind it?

A

recall for beginning of list

less competition and more rehearsal

Q

Proactive Interference (PI)

A

trouble learning new material because previously learned info keeps interfering with new learning

13
Q

what can release proactive interference

A

changing chunk type

(ABC, OIK, ALE –> 123, 492, 478) problem remembering ALE, but no problem remembering 123

Q

Describe the stages of the Atkinson-Shiffrin Model

A

sensory memory–>short-term memory–> long term memory

19
Q

control processes

A

intentional strategies to improve memory

20
Q

what is sensory memory described as now?

21
Q

is the Atkinson-Shiffrin model still relevant?

A

No, cognitive research has since moved onto the theory of working memory

22
Q

Working memory

A

brief, immediate memory for the limited amount of material that you are currently processing

(actively coordinates ongoing mental activity)

control centre

23
Q

what are the characteristics of working memory?

A

active process

capacity and time limited

23
Q

Phonological loop

A

can process limited number of sounds for a short period of time

24
subvocalization
silently pronouncing words when you are reading
24
working memory approach
immediate memory is a multipart system that temporarily holds info and manipulates info while we perform cognitive tasks imagine a brain with hands working with information it receives and choosing how we perform tasks from the information
25
it it easier to remember different or similar sounds in the phonological loop?
different
26
transcranial magnetic stimulation (TMS)
allows magnetic field to stimulate specific location on cortex
26
what brain areas are activated when storing complex, lengthy sentences?
left frontal lobe and left parietal lobe
27
what brain areas are active with the phonological loop?
frontal lobe and temporal lobe in left hemisphere
28
Visuospatial sketchpad
processes both visual and spatial info allows storage of a coherent picture of both visual appearance of objects and relative positions in a scene
29
what brain areas are active in the Visuospatial sketchpad?
right hemisphere, occipital lobe, frontal lobe depending on task frontal and parietal lobe when attentional
29
can one perform two visuospatial tasks at the same time?
hard to perform 2 tasks at the same time
30
central executive
integrates info from phonological loop, visuospatial sketchpad, the episodic buffer, and the long-term memory
31
What activities does the central executive assist with?
focusing attention, selecting strategies, transforming info, coordinating behaviour suppressing irrelevant info
32
daydreaming and the central executive
takes up a lot of the central executive focus leading to more errors on tasks
33
what brain areas are activated for the central executive
frontal lobe
34
compare the executive attention network with the central executive
relatively the same thing. both concepts focus attention
34
what are the characteristics of the episodic buffer
actively manipulate info so that you can interpret an earlier experience, solve new problems and plan future activities Temporary storage with limited capacity
35
Episodic Buffer
temporary storehouse that can hold and combine info from phonological loop, visuospatial sketchpad, and long-term memory
36
working memory capacity and academic performance
increased academic performance with better working memory
37
Working memory and ADHD
crucial deficits in central executive processes problems inhibiting responses leads to lack of attention in many life settings
37
working memory and depression
difficulty with central executive tasks ruminative style= worry about things that are wrong
38
working memory and anxiety
excessive worrying taxes working memory capacity which reduces ability to perform other tasks
