A symbol is a word, mark, sign, drawing, or

object that stands for something else.

A concept is a mental category. A basic tool

of thought, it is a way in which we organize

and simplify information. Concepts put the

world of experience into mental boxes.

There are three basic kinds of

concepts:

(1) conjunctive.

(2) disjunctive.

(3) relational.

Two basic ways to solve problems are to

employ either:

(1)Algorithms: an algorithm is a formula. If

followed carefully, it will always solve the

problem.

(2)Heuristic approaches: Heuristic

approaches employ principles, rules-of-

thumb, and insights to solve problems.

Logical thinking is thinking that employs valid reasoning to reach a correct conclusion.

There are two basic kinds of reasoning involved in logical thinking:

1- Inductive reasoning: is characterized by making observations and gathering information until a general conclusion is reached. It is the basic method of sci ence.

2- Deductive reasoning: is reasoning in which a conclusion follows from a premise. The underlying structure of deductive reasoning is if-then.

The core feature of the creative process

is divergent thinking, thinking that

follows new pathways and explores

alternative possibilities.

Intelligence:

Intelligence is the global ability of

the individual to think clearly and to

function effectively in the

environment.

Theories of intelligence:

General Intelligence (Charles

Spearman):

He concluded that intelligence is general

cognitive ability that could be measured

and numerically expressed.

described a concept he referred to as general

intelligence, or the g factor.

Primary Mental Abilities (Louis L. Thurstone):

Thurstone's theory focused on seven different "primary mental abilities". The abilities that he described were:

• Verbal comprehension.• Reasoning • Perceptual speed • Numerical ability • Word fluency • Associative memory • Spatial visualization

Multiple Intelligences (Howard Gardner):

His theory describes eight distinct intelligences that are based on skills and abilities that are valued within different cultures.

The eight intelligences Gardner described are: • Visual-spatial Intelligence. • Verbal-linguistic Intelligence. • Bodily-kinesthetic Intelligence. • Logical-mathematical Intelligence. • Interpersonal Intelligence.• Musical Intelligence.• Intra personal Intelligence. • Naturalistic Intelligence.

Triarchic Theory of Intelligence (Robert Sternberg):

Sternberg proposed what he refers to as 'successful intelligence,' which is comprised of three different factors:

• Analytical intelligence: This component refers to problem-solving abilities.

• Creative intelligence: This aspect of intelligence involves the ability to deal with new situations using past experiences and current skills.

• Practical intelligence: This element refers to the ability to adapt to a changing environment.

The Concept of an Intelligence Quotient(IQ):

IQ = CA + MA X 100

70 80 90 100 110 120 130

IQ Classification Percent

130 and above Very Superior 2.2

120-129 Superior 6.7

110-119 Bright Normal 16.1

90-109 Normal (or Average) 50.0

80-89 Dull Normal 16.1

70-79 Borderline 6.7

69 and below Cognitively Deficient 2.2

Factors affecting Intelligence:Evidence of genetic influences:

Twin studies suggest that identical twins have

more similar IQ's than fraternal twins.

Siblings reared together in the same home

have more similar IQ's than those of adopted

children raised together in the same

environment.

Evidence of environmental influences:

Identical twins reared apart have less similar IQ's

than identical twins reared in the same

environment.

School attendance has an impact on IQ scores.

Children who are breast fed during the first three to

five months of life score higher on IQ tests at age 6

than same-age children who were not breastfed.
