Intelligence: (Person's capacity to)• Acquire knowledge (i.e. learn and understand)• Apply knowledge (solve problems)• Engage in abstract reasoning. 

Intelligence Quotient: (IQ)• The score you get on an intelligence test. • Originally, it was a quotient (a ratio)-

IQ= MA/CA x 100 [MA is mental age, CA is chronological age].

• Today, scores are calibrated against norms of actual population scores.

The ability to profit from experience, acquire knowledge, thinkabstractly, act purposefully, or adapt to changes in the

environment.

Psychometrics: Measurement of mental abilities, traits, and processes

IQ TEST: MA (Mental Age) is what your score would be for a general age on average, scoring the average score for a 12 year old when you are 7 would give you a MA of 12.

Formal reasoning problems: • All information needed to solve is right there.

Deductive reasoning: • Conclusion follows necessarily from certain premises.• If the premises are true, the conclusion must be true.

Inductive reasoning: • The premises provide support for a conclusion.• It is still possible for the conclusion to be false.
