Cognitive Psychology - Judgements, Decisions and Reasoning Flashcards
reasoning that involves syllogisms in which a conclusion logically follows from premises
deductive reasoning
Reasoning in which a conclusion follows from a consideration of evidence. This conclusion is stated as being probably true rather than definitely true
inductive reasoning
Quality of a syllogism whose conclusion follows logically from its premises.
validity
A series of three statements: two premises followed by a conclusion. The conclusion can follow from the premises based on the rules of logic
syllogism
A syllogism in which the premises and conclusion describe the relationship between two categories by using statements that begin with All, No, or Some.
categorical syllogism
A syllogism is _______ when it makes accurate claims – that is, when the information it contains is consistent with the facts.
true
______ is about whether the conclusion logically follows from the premises based on the form or structure of the syllogism
validity
All of the students are tired. (All A are B)
Some tired people are irritable. (Some C are D)
Some of the students are irritable. (Some A are D)
is this Syllogism valid and/or true?
can be true
not valid
if one or two ________ are not true, the conclusion may not be true, even thought the syllogisms reasoning is valid
premises
reasoning that moves from the general to the specific
deductive reasoning
reasoning that moves from the specific to the general
inductive reasoning
In the past, eating peanuts did not cause me to have an allergic reaction.
Therefore, in the future, I will not have an allergic reaction to peanuts.
what reasoning is this?
inductive
the tendency to think a syllogism is valid if its conclusion is believable or that it is invalid if the conclusion is not believable.
belief bias
conclusions reached are probably true, but not definitely true, because the conclusions drawn are based on generalizations from specific observations that are not always representative of the broader principle or population.
inductive reasoning
A specific situation that is represented in a person’s mind to help determine the validity of syllogisms in deductive reasoning.
mental model
In deductive reasoning, determining if syllogisms are valid by creating mental models of situations based on the premises of the syllogism
mental model approach
if both of the premises are true and the syllogism is valid, then the conclusion is ______
true
syllogisms have two premises and a conclusion and the first premise has the form “If … then.”
