Q

What are ways in which thinking about memory has no evolved?

A
  1. No longer a serial processing model.
  2. Memory is now thought of to be a number of modules which are discreet but interdependent.
  3. Remembering is not always conscious and retroactive.
  4. Not thought of as a computer.
  5. LTM must engage before STM.

Q

Working memory is comprised of what three memory systems?

A

Q

How should working memory be viewed?

A

As a conscious workspace for accomplishing goals rather than a way station or gateway to LTM.

25
How are LTM and Working memory related?
Working memory activates knowledge from the LTM.
26
What is chunking?
The use of knowledge from LTM to increase the capacity of working memory - The grouping of information into larger units rather than single units or digits.
27
What is declarative memory?
Memory for facts and events, much of which can be tested or declared. Two components 1. Semantic of generic 2. Episodic
28
What is semantic memory?
Generic memory for general world knowledge
29
What is episodic memory?
Consists of memories of particular events rather than general knowledge. Often autobiographical.
30
What is procedural memory?
The 'how to' knowledge of procedures or skills. Often occurs without conscious effort.
31
What are the two ways people express knowledge?
1. Explicit memory. | 2. Implicit memory.
32
What is explicit memory?
Memory that is expressed through conscious recollection. The conscious retrieval of information.
33
What are the two components to explicit memory?
1. Recall - spontaneous recollection of information from the LTM. 2. Recognition - The identification of something previously seen or heard.
34
What is implicit memory?
Memory that is expressed in behavior but does not require conscious recollection.
35
What neural regions are involved in the consolidation of explicit memories?
The hippocampus and adjacent regions of the cortex.
36
What are the two components of everyday memory?
1. Retrospective memory | 2. Prospective memory
37
What is retrospective memory?
memory of things from the past.
38
What is prospective memory?
Memory for things that need to be done in the future. Remembering to remember Remembering what to remember.
39
What is encoding?
The storage of information in LTM requires that it be cast into a representational form. The type and level of encoding influences the accessibility of information.
40
What are the two levels of LTM processing?
1. Shallow processing | 2. Deep processing
41
What is shallow processing?
Focus on the physical characteristics of the stimulus.
42
What is deep processing?
Focus on the meaning of the stimulus.
43
What is context dependent memory?
Information is easier to recall when it is encoded and retrieved in the same context.
44
What is Mood (state) congruent memory?
Information is easier to recall when it is encoded and retrieved in the same emotional state.
45
What is the encoding specificity principle?
Ease of retrieval depends on the match between the way information is encoded and later retrieved.
46
What is the spacing effect?
Superiority of memory for information rehearsed over .longer intervals.
47
What is the best way to encode and retrieve information?
To store memory in multiple representational modes such as words, images and sounds.
48
Explain how pieces of information stored in memory for networks of association.
LTM is organized in clusters of information that are related in meaning. 1. The network is comprised of interconnected nodes. 2. A node may contain thoughts, images, smells, emotions or any other information.
49
What is spreading activation theory?
Activating one node in a network triggers activation in closely related nodes.
50
How are both encoding and retrieval of information affected by schemas?
When confronted with a novel event people match it against schemas stored in memory.
51
What is a schema?
Patterns of thought, or organized knowledge structures that render the environment relatively predictable.
52
How do schemas affect the way people remember.
1. By influencing the way information is encoded. | 2. By shaping the way information is reconstructed.
53
What are the seven sins of memory described by Daniel Schacter?
1. Transience: memories fade with time 2. Absent-mindedness 3. Misattribution: source amnesia 4. Suggestibility: thinking we remember 5. Bias: distortions in recall 6. Persistence: recurring memories 7. Forgetting: inability to remember.
54
How is memory subject to errors and bias'?
Memory can be primed | Memory is altered by emotional factors.
55
What is Flashbulb memory?
Vivid memories of exciting or highly consequential events.
56
Why are Flashbulb memories unreliable?
They often provide a snapshot or clarity that can be inaccurate or even entirely wrong.
57
What are three theory's of forgetting?
1. Decay theory 2. Interference theory - conflict between new and old. 3. Motivated forgetting.
58
Why is it difficult to address the issue of false memories of childhood trauma?
It is almost impossible to distinguish between false and recovered memories.
59
What is anterograde amnesia? And what causes it?
Involves the inability to retain new memories, usually caused by damage to the temporal lobe particularly the hippocampus and subcortical region.
60
What is retrograde amnesia? And what causes it?
Involves loosing memories from before the time that the persons brain was damaged. Tumors, strokes, ECT.
