Q

idea that memory system has ENOGUH RESOURCES to transfer items at BEGINNING of list into LTM

25
idea that items at END of list = STILL in LTM + are therefore AVAIL for recall
RECENCY
26
2 brain regions involved in CONSOLIDATION
1. HIPPOCAMPUS 2. AMYGDALA
27
PROCESS OF CONSOLIDATION IN THE BRAIN
1. HIPPOCAMPUS receives info abt its going on from SENSORY/MOTOR ASSOC CORTICES, BASAL GANGLIA + AMYGDALA 2. it processes info 3. thru EFFERENT connections w those regions, it MODIFIES mems being consolidated there 4. LINKS mems together in ways that allow us to REMEMBER the relationships among elements of mems
28
memories = subject to modification thru ___ + ____
REACTIVATION + RECONSOLIDATION
29
process of CONSOLIDATION of a memory that occurs after the original CONSOLIDATION that can be triggered by a reminder of the OF stimulus
RECONSOLIDATION
30
memories we are NOT necessarily conscious fo (IMPLICIT KNOWLEDGE)
NONDECLARATIVE MEMORY
31
memories of events/facts we can think/talk about
DECLARATIVE MEMORY
32
memory of a collection of PERCEPTIONS OF EVENTS organized in time + identified by a particular context
EPISODIC (AUTOBIOGRAPHICAL) MEMS
33
memory of FACTS/GENERAL INFO/CONCEPTUAL KNOWLEDGE
SEMANTIC MEMS
34
brain region involved in DECLARATIVE MEM
HIPPOCAMPUS
35
brain region involved in PROCEDURAL MEM
BASAL GANGLIA
36
brain region involved in EMOTIONAL MEM
AMYGDALA
37
brain region involved in 'WORKING WITH' MEM
PREFRONTAL CORTEX
38
concept involved in PERCEPTUAL MEMORY that is an alteration of response to a stimulus as a result of PRIOR EXPOSURE
PRIMING
39
concept involved in PROCEDURAL MEMORY that is a learning procedure where the effects of a particular bhvr in a particular situation INCR (REINFORCE)/DECR (PUNISH) the probability of the bhvr
INSTRUMENTAL/OPERANT CONDITIONING
40
series of connected memes that become automatic w practice
MOTOR LEARNING
41
concept in EMOTIONAL MEMORY that = the assoc btwn STIMULUS + VALENCE
CONDITIONED FEAR RESP
42
how PLEASANT/UNPLEASANT a stimulus is
VALENCE
43
concept in EMOTIONAL MEMORY where if CONDITIONED stimulus = repeated without the UNCONDITIONED stimulus enough then CONDITIONED RESPONSE disappears
EXTINCTION
44
concept in NON-ASSOCIATIVE MEMORY that involves IGNORING incoming info that = NOT relevant
HABITUATION/DESENSITIZATION
45
learning to recognize a particular stimulus
PERCEPTUAL LEARNING
46
learning RELATIONSHIPS among individuals stimuli
RELATIONAL LEARNING
47
learning to automatically make a particular resp in presence of a particular stimulus
STIMULUS-RESPONSE LEARNING
48
AUTOMATIC/UNVOLUNTARY reflexes that do NOT have to be learned
TYPE OF BHVR IN CLASSICAL CONDITIONING
49
BRAND NEW/VOLUNTARY bhvrs that HAVE been learned
TYPE OF BHVR IN OPERANT CONDITIONING
50
assoc btwn 2 stimuli
TYPE OF ASSOCIATION IN CLASSICAL CONDITIONING
51
assoc btwn stimulus + response
TYPE OF ASSOCIATION IN OPERANT CONDITIONING
52
stimulus that elicits UNLEARNED/REFLEXIVE resp
UNCONDITIONED STIMULUS (US)
53
LEARNED/REFLEXIVE bhvrl response to an UNCONDITIONED STIMULUS
UNCONDITIONED RESPONSE (UR)
54
stimulus that elicits LEARNED/REFLEXIVE response following pairing w UNCONDITIONED STIMULUS
CONDITIONED STIMULUS (CS)
55
LEARNED/REFLEXIVE resp to a CONDITIONED STIMULUS established after repeated paragon of UNCONDITIONED + CONDITIONED STIMULI
CONDITIONED RESPONSE (CR)
56
hypothesis/rule that cellular basis of learning involves strengthening of synapse that = repeatedly active when postsynaptic neuron fires
HEBBIAN LEARNING (HEBB RULE)
57
after several pairings of 2 stimuli + after several increments of strengthening → synapse btwn 2 types of nuerons becomes strong enough to cause motor neuron to fire by itself
HOW HEBB RULE = MECHANISM FOR CLASSICAL CONDITIONING
58
long term INCR in excitability of a neuron to a particular synaptic input caused by RPTD HIGH-FREQ activity of that input
LONG TERM POTENTIATION (LTP)
59
idea that LTP strengthens existing synapses + creates new ones
