Q

Contrast shallow and deep processing.

A

shallow - processing of info involves little attention to meaning and focuses on superficial aspects like physical features
deep - processing of info that involves close attention to meaning and connections to other things

Q

What is the difference between a free recall and cued recall procedure? What typically results in better recall?

A

free recall asks participants to remember as many words as possible without help
cued recall asks participants to remember as many words but were given a retrieval cue
-results in better recall

Q

3 Hypotheses meant to explain the reminiscence bump

A

self image hypothesis - enhanced memory for events that formed self identity
cognitive hypothesis - encoding better for rapid change, followed by stability
cultural life script hypothesis - personal events easier to recall when they fit cultural lifescript

25
What is a source monitoring error? (source misattribution)
misunderstanding of where source of a memory is from
26
What do the results of Bartlett's "War of the Ghosts" experiment suggest about how recall changes over time?
recall accuracy declined overtime, recall was shaped by cultural knowledge. native american aspects were changed for details from 1930s english culture. -memory comes from multiple sources
27
What is nostalgia?
memory involving sentimental longing for the past May serve as a self-regulation mechanism
28
Why are memories elicited by stimuli like music and taste called involuntary memories?
brings back memories that you do not intentionally recall, they are cued by sensory stimulation
29
What is conceptual knowledge?
knowledge that allows us to recognize things/events and make inferences about their properties
30
What are concepts and categories?
concepts - mental representations of individual or class of items category - includes all possible examples of a concept
31
Describe the prototype approach to categorization.
membership into category is determined by comparing it to a "typical" member of a category high prototypicality means a category member closely resembles category prototype
32
What is the typicality effect?
ability to verify highly prototypical objects quickly
33
What is the exemplar approach to categorization? How does it differ from the prototype approach?
membership determined by whether an object is similar to actual members of categories that they have seen in the past prototype approach compares to avg. member, not necessarily real
34
Which approach to categorization better describes how we categorize things?
depends on learning stage: initial learning - prototype gain more knowledge of a category - exemplar depends of category stage: small categories - exemplar large categories - prototypes
35
Semantic Network Model (what is cognitive economy and inheritance)
model represents categorization as nodes (concepts) connected by links (relationships among concepts) maintains cognitive economy by having shared properties stored at higher nodes inheritance - properties at higher levels apply to all connected low level items
36
What is spreading activation?
when node is activated, activity spreads out along related links and primes other nodes
37
What is the traditional model of cognition?
cognition is separate from perceptual and motor systems
38
What is embodied cognition?
cognition is largely grounded in perceptual and motor systems
39
Define reasoning
process by which we come to a conclusion
40
Define conclusion
judgement reached via reasoning process
41
Define decision
involves choosing among alternatives
42
What is deductive reasoning?
starting at general principles to reach specific conclusions
43
What is inductive reasoning?
start from a specific observation to reach general conclusion
44
What is confirmation bias?
seek out and give more value to info that conforms to personal beliefs while ignoring info that goes against it
45
What is myside bias?
type of confirmation bias where people evaluate evidence in a way that bias their existing opinions and attitudes
46
What is the availability heuristic?
involves estimating likelihood of an occurrence based on the ease with which they come to mind
47
What is the representativeness heuristic?
involves judging likelihood of individual instances being part of a larger category based on its similarity to characteristics we normally associate with that category - shy librarian v. truck driver
48
What is the conjunction fallacy?
probability of 2 event occurring together cannot be higher than probability of each alone
49
What is a syllogism?
consist of 2 premises followed by a conclusion
50
What is a categorical syllogisms?
premises that start with all, no, or some
51
What is a conditional syllogisms?
start with a premise of the form If... then and then a statement
52
What is a valid conclusion?
where conclusion logically flows from the premises
53
What is a true conclusion?
syllogism's conclusion is true
54
What is the Wason card problem?
E K 4 7, people have difficulty solving abstract problem because of confirmation bias and fail to perform the falsification principle, but can solve easily when related to real life situation
55
Define risk aversion. Describe asymmetry between losses v. gains.
tendency to avoid taking risks, tend to avoid risks in our favor because we anticipate feeling more worse for a loss than positive for a win
56
How do our expected emotions in response to gains/losses compare to our actual emotions?
Expected negative was very large and expected positive was very small, in reality both are same size +-
57
What is the status quo bias?
tendency to do nothing and stick with the default option when faced with a decision
58
What is the framing effect? Understand example Tversky & Kahneman
decisions influenced by how choices are stated Option A - save 200 Option B - 1/3 probability save everyone 70%+ chose option A Option C - 400 people die Option D - 1/3 probability no one will die 70%+ chose option D when proposed as gains we chose risk aversion, when proposed as losses we have risk taking strategy
59
What is the ultimatum game?
Game where a proposer has $10 and they decide how to split it between 2 people, receiver can choose whether to accept or reject and nobody gets money. goes against utility theory because people start to reject offers of $3 or less. people are more likely to accept unfair offer from computer
60
What are the characteristics of System 1? What is it useful for?
automatic, fast, intuitive system. useful for making decisions quickly and navigating daily life
61
What are the characteristics of System 2? What is it useful for?
slower, deliberative, thoughtful system. good for problem solving
62
What's the value of having 2 different systems of reasoning?
Reduces cognitive load by using automatic processing most of the time, and allows us to focus cognitive energy on problem solving when we need slower thinking
