25
Retrieval
The act of accessing stored information from one's memory
26
Retrograde amnesia
Loss of memories that take place prior to brain damage
27
Retrograde amnesia
Loss of memories that take place before brain damage
28
Ribot's law
Retrograde amnesia follows a temporal gradient
29
Semantic memory
Knowledge based on facts (declarative, explicit)
30
Sensory memory
A form of short-term memory lasting at most seconds, sensory information; separate for every sense
31
Echoic memory
Auditory sensory memory
32
Iconic memory
Visual sensory memory
33
Short-term memory
Retention of information for seconds or minutes
34
Storage
Permanent record of information due to encoding (acquisition and consolidation)
35
Temporal gradient
Effects of retrograde amnesia tend to be the greatest for events closest to the brain injury (See Ribot's law)
36
Temporally limited amnesia
Retrograde amnesia that does NOT span the entire life, only some time leading up to the injury
37
Transient global amnesia TGA
Sudden, dramatic amnesia that is both anterograde and retrograde, lasts only hours
38
Working memory
Maintenance and manipulation memory, has a limited capacity (7±2); Planning, computations, etc.
39
Left-hemisphere damage can result in selective impairment in _______ memory.
verbal
40
Right-hemisphere damage can result in selective impairment in _______ memory.
nonverbal-
41
According to outdated theories, Alzheimer's disease is caused by the deposition of _______.
beta-amyloid plaques
42
Alzheimer's is now attributed to _______.
neurofibrillary tangles
43
Alzheimer's disease AD
Most common form of dementia, associated with accumulation of amyloid proteins and neurofibrillary tangles
44
Vascular dementia
Second most common form of dementia, caused by decreased oxygenation of neural tissue and cell death, resulting from ischemic or hemorrhagic infarcts, rupture of small arterial vessels in the brain associated with diabetes, and rupture of cerebral arteries caused by the accumulation of beta-amyloid plaques in the walls of the vessels, CAN cooccur with AD
45
Frontotemporal lobar dementias
A heterogeneous group of neurodegenerative diseases characterized by accumulations of different proteins in the frontal and temporal lobes Result in language and behavioral changes, may overlap with AD
46
Serial reaction-time task
The point: healthy patients DO react faster to the sequence over time, but they are unaware of doing so (procedural knowledge, NOT declarative)
47
Semantic priming
The prime and target are different words from the same semantic category Ex. dog and bone, lake and fish
48
Delayed nonmatch-to-sample task
Monkey is shown where a food reward is, they must identify where it is to get it; afterward, the reward is placed on the other side (the monkey cannot see this), and the monkey has to pick the new (non-matched) one
49
Neurons that activate when rats are in a particular place and facing a particular direction have been identified in the hippocampus and are called _______.
place cells
50
Binding-of-items-and-contexts BIC model
This model proposes that the perirhinal cortex represents information about specific item and the parahippocampal cortex represents information about the context in which these items were encountered The hippocampus binds these two things together
51
Relational memory theory
Proposes that the hippocampus supports memory for all manner of relations
52
False memories
DO elicit activity in the same retrieval networks that true memories activate, though true memories are associated with GREATER activity
53
Hemispheric encoding/retrieval asymmetry HERA model
FALSIFIED Episodic encoding was predominantly a left-hemisphere process, while episodic retrieval was predominantly a right-hemisphere process
54
The activation pattern for the contrast between successfully retrieved old items and successfully rejected new items is known as the _______.
successful retrieval effect
55
Working memory maintenance hypothesis
Proposes that activation of the parietal cortex is related to the maintenance of information in working memory
56
Multimodal integration hypothesis
Suggests that parietal activations indicate integration of multiple types of information.
57
Attention-to-memory model
Argues that the dorsal regions of the superior parietal lobule are necessary for top-down search of episodic memory for specific content, And that the ventral regions of the inferior parietal lobule are critical to capturing attention once the salient content is identified
58
WHat three properties are suggested by Hebbian Learning
Cooperativity, associativity, specificity
59
Cooperativity
More than one input must be active at the same time
60
Associativity
Weak inputs are potentiated when co-occurring with stronger inputs
61
Specificity
Only the stimulated synapse shows potentiation.
