1
Q

Long-term Memory (LTM)

A

Thought as an archive of info about past events and knowledge learned
- Storage can be from moments ago to as far back as you can remember
-More recent usually more detail

Q

Serial Position Curve (Murdoch)

A

Memory is better for words presented at the beginning of a heard list and the end. Participants wrote down the words they remembered

Q

Primacy Effect

A

Memory is better for stimuli presented at the beginning
- Occurred because participants had more time to rehearse the earlier items and experienced less interference while encoding

Q

Recency Effect

A

Memory is better for stimuli presented at the end of the list
- Occurs because the stimuli were still active in STM at the point at which memory was being tested
Although introducing a delay would remove this effect

Q

Proactive interference

A

Occurs when info learned previously interferes with learning new information
- French vocab learned in elementary can iinterefere with Spanish learning in highschool

Q

Retroactive interference

A

Occurs when learning interferes with remembering old learning
- Hard time remembering your old phone number when you have mastered your new one

Q

The Wickens Experiment

A

An example of proactive interference
- The condition where all 4 trials were fruit names, and individuals had a hard time encoding the later trials
- In the other condition where the 1st three trials were jobs and the last was fruit the 1st and 4th trial was better encoded.

Q

Double dissociation in STM and LTM

A

If the STM is impaired then the LTM is ok (K.F)
If the LTM is impaired then the STM is ok (H.M)

Q

Episodic Memory

A

-Memory for personal events
- Involves ‘mental time travel’
-No guarantee accuracy
- Multidimensional in nature: can include sensory details, emotional, and contextual

Q

Semantic Memory

A
  • memory for facts and knowledge
  • Does not invlove mental time travel
  • General knowledge

Q

What happens if episodic details are lost?

A

Semantic details can remain
- Accquiring knowledge may start as episodic but fade to semantic

15
Q

Double dissociation of Episodic and Semantic Memory

A

-K.C damaged hippocampus; no episodic memory, can relive any events of his past but semantic memory is intact and can remember general info about the past

-LP: impared semantic memory, episodic memory for past events was preserved

16
Q

What can you do to enhance semantic memory?

A

If you associate it with episodic details

17
Q

Autobiographical Memory*

A

Memory of specific experiences, includes both episodic and semantic memory

18
Q

Personal Semantic Memory*

A

Semantic memories that have personal significance

19
Q

What is the Remember/Know Procedure by Petrican and what are the components?

A

Procedure to measure familiarity and recollection
-Research has shown that longer interval times from original encoding increases forgetting
1. Remember response
2. Know response
3. Don’t know response

20
Q

Remember response

A

If a stimulus is familiar and the circumstances under which it was encountered can be remembered
(smelling and old perfume bringing back memories)

21
Q

Know response

A

If the stimulus is familiar, but you can’t remember experiencing it earlier

22
Q

Don’t know response

A

Don’t remember the stimulus at all

23
Q

What were the results of the Remember/ Know procedure?

A

It shows the semanticization of remote memories
- Loss of episodic details for memories of long-ago events
-Memories of the most recent events are more likely to include episodic memory than less recent.

24
Implicit/Declarative Memory
Unconcious memory
25
Procedural Memory
Memory for actions - No memory of where it was learned -Perform without concious thought -People who cannot for LTM can still learn new skills (HM could still learn do mirror tracing and get good with practice without ever remembering learning to do so)
26
Priming
Prior exposure to a stimulus that changes a subsequent response
27
Conditioning
Pairing a neutral stimulus with a reflexive response (Pavlov)
28
Expert-Induced Amnesia
Expertise in a skill may be carried out with such a hig degree of AUTOMATICITY that the individual may have little to no recollection of what happened -Ex. Sometimes hockey players will black out and not remember the game
29
Reptition Priming
Prior exposure to a stimulus makes it easier or faster to process that same stimulus again later -You see the word "elephant" on a screen during a memory task. -Later, when asked to complete the word fragment "ele___", you’re more likely to fill in "elephant"—and more quickly—than if you hadn’t seen it before.
30
Incidental Processing
Unintentional or unconscious processing of information - Reading a story for fun, not to memorize it. Later, you’re surprised that you remember many of the details or words from it
31
Explicit memory test
assesses recall memory
32
Word Stem completion
Assesses implicit memory
33
What did the Graf et al. experiment find on implicit and explicit memory?
Found relative impairment for implicit memory in the amnesiac group. Demonstrates that implicit memory can remain intact even when explicit memory has been compromised
34
What were the conclusions from the Perfect and Askew study with magazines?
Participants who had seen an ad in the magazine before generally rated the ad higher. This is related to the mere exposure effect and the propaganda effect
35
Mere exposure effect
We tend to like things we have already been exposed to
36
Proaganda Effect
We tend to rate statements as being true if we've read or heard them before
