Q

What is anchoring?

A

When provided with a potential answer to a
question, people use that answer as a reference point in selecting their answer.
This happens even if the participant knows the high number has no impact on the answer.

Q

If category membership is unknown, it can be inferred based on two types of information:

A

When base rates are available, people often completely ignore diagnostic information as a source of information. True or false
false. When diagnostic information is available, people often completely ignore base rates as a source of information
26
Define cognitive illusion
even when people know the correct answer, they may be drawn to an incorrect conclusion based on the structure of the problem
27
What is the dilution effect?
Including Non-Diagnostic Information along with Diagnostic Information, leads people to rely less on diagnostic information in making judgements
28
With only diagnostic information people treat Frank in a stereotypical way, leading to more extreme estimates. True or false
With only diagnostic information people treat Frank in a stereotypical way, leading to more extreme estimates
29

30
What is a conjunction fallacy?
The probability of a co-occurrence of two outcomes cannot be greater than the probability of each outcome alone
31
_______________ is used in making judgments about the attributes of members of a category
The Representativeness Heuristic

33
what does it called if two variables rise and fall together?
covarience
34
What are the problems with covariation detection?
People tend to only look at one cell of the evidence. 1. The cell that supports their hypothesis: *2. The cell that refutes their hypothesis:
35
What is positive test strategy also known as?
Confirmation bias
36
Define positive test strategy/confirmation bias.
Testing a hypothesis by seeking cases that match it
37
What is the problem with the positive test strategy?
If only look for things that confirm hypothesis, there will be an overrepresentation of confirmations
38
What are the "hows" of positive test strategy?
-Biased memory search -Biased evidence seeking (can lead to self-fulfilling prophecy)
39
The positive test strategy tends to lead to
biased conclusions when stimuli are complex such that cases exist that fit the hypothesis, regardless of whether the hypothesis is actually true
40
Single-chute survey questions do not produce misleading results . True or False?
false. It leads you to misstate and mistake your position
41
What is the first tenant of prospect theory?
Losses loom larger than equivalent gains
42
Define loss aversion.
the tendency to avoid losses over achieving equivalent gains.
43
what is the framing effect?
Decision-making can be influenced by the way alternatives are worded
44
What is mental accounting:
helps to explain the way we post a problem (framing) and whether it is phrased in terms of gains or losses influences our decision
45
What is intuition?
An effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning
46
True or false: consciousness has a low processing capacity
