Cognitive: Reasoning terms Flashcards
Define reasoning
The cognitive process of deriving new information from old information
What is meant by deductive reasoning?
Drawing logically necessary conclusions from given information
What is meant by inductive reasoning?
The process of inferring probable conclusions from given information
What are premises?
Statements assumed to be true from which conclusions are drawn
What is meant by the term valid?
Valid arguments are those in which the conclusions must be true if the premises hold true
Name and describe the two types of deductive reasoning
Prepositional reasoning is reasoning about statements connections such as ‘and’ ‘or’ ‘not’ ‘if.’ Syllogistic reasoning is reasoning about groups/sets using statements connected by logical relations of ‘some’, ‘none’, ‘all’ and ‘some not.’
What are inference rules?
Rules for reaching a conclusion given a particular pattern of propositions
What does modus tollens state
Given ‘if p then q’ and ‘not q’ then we can infer ‘not p’
What does modus ponens state?
Given ‘if p then q’ and given p is true, it follows q is true
What is meant by double negation?
If not not p then p
Name and describe the two main mistakes when arguing from conditionals
Affirming the consequent; ‘if p then q’ and ‘q is true’ then ‘p’ is true.
Denying the antecedent; ‘If p then q’ and ‘not p’ then ‘not q’
what is disjunctive syllogism?
premises: ‘p or q’ ‘not p’
Conclusion: ‘Therefore q’
What is the mental models approach?
The view that people use logical reasoning problems by forming mental representations of possible states of the world and draw inferences from those representations.
What is categorical syllogism
What conclusion, if any, follows from assumptions about category membership
What is meant by the atmosphere effect?
The tendency to draw conclusions in syllogisms that are over influenced by the form of the premises rather than the logic of the argument.
