Q

semantic memory

A

our knowledge of facts and concepts about the world (e.g., that the absolute value of −90 is greater than the absolute value of 9 and that one definition of the word “affect” is “the experience of feeling or emotion”).

Q

classical conditioning effects

A

we learn, often without effort or awareness, to associate neutral stimuli (such as a sound or a light) with another stimulus (such as food), which creates a naturally occurring response, such as enjoyment or salivation

Q

priming

A

changes in behavior as a result of experiences that have happened frequently or recently

the activation of knowledge (e.g., we can prime the concept of “kindness” by presenting people with words related to kindness) and to the influence of that activation on behavior (people who are primed with the concept of kindness may act more kindly)

eg, word fragment test

Q

Short-term memory (STM)

A

the place where small amounts of information can be temporarily kept for more than a few seconds but usually for less than one minute

info that we turn our attention to and that becomes available to us for processing

it is actually a set of procedures or operations, not a store

Q

central executive

A

the part of working memory that directs attention and processing

e.g., solving a math problem and then remembering a letter multiple times

central executive will make use of whatever strategies seem to be best for the given task (e.g., maintenance rehearsal, chunking)

Q

long-term memory (LTM),

A

memory storage that can hold information for days, months, and years. The capacity of long-term memory is large, and there is no known limit to what we can remember

25
Encoding
the process by which we place the things that we experience into memory. Unless information is encoded, it cannot be remembered.
26
elaborative encoding
process new information in ways that make it more relevant or meaningful elaborate on new information to encode it, eg by linking it to other information or contextualizing it, encode it in a way that relates to yourself
27
Hermann Ebbinghaus
a pioneer of the study of memory He discovered an important principle of memory: Memory decays rapidly at first, but the amount of decay levels off with time
28
spacing effect
the fact that learning is better when the same amount of study is spread out over periods of time than it is when it occurs closer together or at the same time
29
overlearning
continuing to practice and study even when we think that we have mastered the material this is beneficial
30
Retrieval
the process of reactivating information that has been stored in memory
31
Context-dependent learning
an increase in retrieval when the external situation in which information is learned matches the situation in which it is remembered
32
state-dependent learning
superior retrieval of memories when the individual is in the same physiological or psychological state as during encoding
33
primacy effect
a tendency to better remember stimuli that are presented early in a list
34
recency effect
the tendency to better remember stimuli that are presented later in a list
35
serial position curve
results curve that results from the primacy and recency effect
36
Retroactive interference
learning something new impairs our ability to retrieve information that was learned earlier
37
Proactive interference
earlier learning impairs our ability to encode information that we try to learn later
38
categories
memories in LTM are linked together into networks of associated memories that have features in common with each other
39
spreading activation
occurs when activating one element of a category activates other associated elements.
40
prototype
the member of the category that is most average or typical of the category these are retrieved faster than others that are less prototypical
41
schemas
patterns of knowledge in long-term memory that help us organize information schemas about objects (that a triangle has three sides and may take on different angles), about people (that Sam is friendly, likes to golf, and always wears sandals), about events (the particular steps involved in ordering a meal at a restaurant), and about social groups (we call these group schemas stereotypes)
42
LTM Retention
LTM involves a gradual strengthening of the connections among the neurons in the brain
43
long-term potentiation (LTP)
the strengthening of the synaptic connections between neurons as result of frequent stimulation
44
consolidation
period of time in which LTP occurs and in which memories are stored
45
hippocampus in memory
serves as a preprocessor and elaborator of information helps us encode information about spatial relationships, the context in which events were experienced, and the associations among memories holds the memory for a short time and then directs the information to other parts of the brain, such as the cortex, to actually do the rehearsing, elaboration, and long-term storage
46
cerebellum and the amygdala in memory
concentrating on implicit and emotional memories, respectively
47
retrograde amnesia,
a memory disorder that produces an inability to retrieve events that occurred before a given time
48
Anterograde amnesia
is the inability to transfer information from short-term into long-term memory, making it impossible to form new memories
49
Glutamate
a neurotransmitter and a form of the amino acid glutamic acid, is perhaps the most important neurotransmitter in memory When animals, including people, are under stress, more glutamate is secreted, and this glutamate can help them remember also serotonin, estrogen and epinephrin
50
Cognitive biases
errors in memory or judgment that are caused by the inappropriate use of cognitive processes
51
Source monitoring
the ability to accurately identify the source of a memory. ie, real or a dream or source of the information
52
sleeper effect
attitude change that occurs over time when we forget the source of information
53
confirmation bias
the tendency to verify and confirm our existing memories rather than to challenge and disconfirm them comes from an over-reliance on schemas leads us to remember information that fits our schemas better than we remember information that disconfirms them
54
Functional fixedness
occurs when people’s schemas prevent them from using an object in new and nontraditional ways
55
misinformation effect
errors in memory that occur when new information influences existing memories
56
overconfidence
the tendency for people to be too certain about their ability to accurately remember events and to make judgments
57
flashbulb memory
a vivid and emotional memory of an unusual event that people believe they remember very well
58
heuristics
information-processing strategies that are useful in many cases but may lead to errors when misapplied
59
representativeness heuristic
we base our judgments on information that seems to represent, or match, what we expect will happen, while ignoring other potentially more relevant statistical information eg, representative examples of our idea of what randomness should look like
60
gambler’s fallacy
people who see a flipped coin come up “heads” five times in a row will frequently predict, and perhaps even wager money, that “tails” will be next
61
availability heuristic
The tendency to make judgments of the frequency or likelihood that an event occurs on the basis of the ease with which it can be retrieved from memory
62
salience bias
we are more likely to attend to, and thus make use of and remember, some information more than other information we tend to attend to and remember things that are highly salient, meaning that they attract our attention Things that are unique, colorful, bright, moving, and unexpected are more salient
63
Cognitive accessibility
the extent to which knowledge is activated in memory, and thus likely to be used in cognition and behavior people have highly accessible schemas about environmental issues, eating healthy food, or drinking really good coffee. When schemas are highly accessible, we are likely to use them to make judgments of ourselves and others, and this overuse may inappropriately color our judgments.
64
counterfactual thinking
The tendency to think about and experience events according to “what might have been”
