Thinking and Deciding (CH. 12) Flashcards
What is Frequency Estimate?
An essential step in judgment, in which someone makes an assessment of how often they have experienced or encountered a particular object or event
What is Attribute Substitution?
A commonly used strategy in which a person needs one type of information but relies instead on a more accessible form of information. This strategy works well if the more accessible form of information is well correlated with the desired information. An example is the case in which someone needs information about how frequent an event is in the world and relies instead on how easily they can think of examples of the event
What is Availability Heuristic?
A particular form of attribute substitution in which the person needs to judge the frequency of a certain type of object or the likelihood of a certain type of event. For this purpose, the person is likely to assess the ease with which examples of the object or event come to mind; this “availability” of examples is then used as an index of frequency or likelihood
What is Representative Heuristic?
A strategy that is often used in making judgements about categories. This strategy is broadly equivalent to making the assumption that, in general, the instances of a category will resemble the prototype for that category and, likewise, that prototype resembles each instance
Dual-Process Models of Decision Making
Type 2: slower, effortful thinking (more likely to be correct)
Type 1: fast and automatic thinking (relies on heuristics)
What is Covariation?
A relationship between two variables such that the presence (or magnitude) of one variable can be predicted from the presence (or magnitude) of the other. Covariation can be positive or negative. If it is positive, then increases in one variable occur when increases in the other occur. If it is negative, then decreases in one variable occur when increases in the other occur
What is Confirmation Bias?
A tendency to seek out, and accept without scrutiny, information and statements consistent with your belief
Representativeness Heuristic: The Linda Problem, Which Option is More Likely?
Option 1: Linda is a bank teller
Option 2: Linda is a bank teller and is active in the feminist movement
“Bank teller and feminist” is just a subset of bank teller; therefore it cannot be more likely
What is the Somatic Marker Hypothesis?
- Emotions are associated with different
bodily (i.e., somatic) responses, such as
increased heart rate and sweating for
anxiety. - When we notice these markers of
emotion, it influences our decisions. - Dependent of orbitofrontal cortex
(OFC)
What is Belief Perseverance?
A tendency to continue endorsing a belief even when disconfirming evidence is undeniable
What is the Sunk Cost Fallacy?
An irrational tendency to continue an endeavor because of prior time, money, or effort costs
What is Base-Rate Information?
Information about the broad likelihood of a particular type of event (also referred to as “prior probability”)
What is Diagnostic Information?
Information about a particular case
What is Induction?
A pattern of reasoning in which a person seeks to draw general claims from specific bits of evidence
What is Deduction?
A process through which a person starts with claims, or general assertions, and asks what further claims necessarily follow from these premises
