Q

Explain how a “partial report” provides evidence for sensory memory.

A

Individuals are shown a stimulus and are able to provide partial information from different element of that stimulus. However because of the limited amount of time something stays in sensory memory, if they are asked to provide information about the whole stimulus, or about different parts of the stimulus in series, they won’t be able to do it.

(Classic experiment was 3 lines of random letters, asked to provide a list of just one of the lines. By the time they were done with that, they had forgotten the rest of the lines.)

Q

What is displacement theory (as it concerns memory?)

A

That there are a limited number of slots that can fit into short term memory and if something else fills that slot something else is displaced (or removed) from short term memory.

Q

What are the elements of Baddeley’s model of working memory?

A

Information flows from a central executive system into a phonological loop (short-term auditory store), a visuospatial sketchpad (short-term visual store), and/or a episodic buffer, then memory can flow from these systems into long term memory

the idea that material is more likely to be recalled if it's remembered in the same context under which it was learned.

encoding specificity principle
34
What types of memories do you know you know?

What type of memory requires no conscious awareness of knowing something?
Implicit memory
37
What types of memories are implicit memories?
Procedural memory, classical conditioning, priming
38
What is procedural memory
Knowing how to do something, especially physical actions and motor skills.
39
What are the three main processes involved in memory?
Encoding, storage, and retrieval
40
What is encoding as it relates to memory?
transforming information into a form more easily stored by the brain.
41
What are methods of more effectively encoding information into memory?
1) Mnemonics 2) Clustering 3) Organization 4) Elaborative encoding 5) Dual Encoding 6) Rehearsal 7) Self-reference
42
What is elaborative encoding?
The use of meaning and associations to remember things
43
What is dual encoding?
Items that will be better remembered if they are both visually and semantically encoded
44
What is the Method of Loci
Creating associations between locations that are well known and creating associations between the two.
45
Who suggested the theory of dual encoding?
Allan Paivio
46
Who found that memories are not stored in any one specific place but diffusely throughout the brain?
Karl Lashley
47
Who discovered that memory is reconstructive?
Frederick Barlett
48
How does the concept of depth of processing relate to memory?
The more deeply something is learned (ie for semantics and meaning and not just pronunciation etc.) the easier it is to learn and recall
49
Who studied memory and depth of processing?
