Intelligence - Modern Intel Testing

Question 1

Purpose of the Initial Intel Testing?

Answer 1

It started as an educational diagnostic tool to identify which students needed extra help from teachers

Modern intel tests are assessment tools to gauge a persons intel

Question 2

What do intelligence tests provide us with? And what two types are there?

Answer 2

They provide an intel quotient (IQ)

There are two types of IQ Scores

1. MENTAL AGE

The first intel tests gauges a persons mental age DIVIDED BY their actual age (chronological age)

IQ = Mental Age / Chron Age X 100

ISSUES are, scores of IQ tests stop changing around 16 yrs of age

“Mental age” method is great for identifying the mental skills for children, not good for adults.

2. DEVIATION IQ

Is the difference between your performance on an IQ test and the performance of other people the SAME AGE as you

IQ = 100 + Your Score - Age average

Question 3

What are the common IQ tests for CHILDREN and ADULTS?

Answer 3

CHILDREN

• WPPSI (Wechsler Preschool and Primary Scale of Intelligence)
• WISC (Wechsler Intelligence Scale for Children)

ADULTS

• WAIS (Wechsler Adult Intelligence Scale)
• SAT (Scholastic Aptitude Test)
• GRE (Graduate Record Examination)

Different IQ tests are used for different people of diff ages (first 16 yrs for kids), because knowledge acquisition is very quick, so certain types of questions stop becoming meaningful metrics after specific ages for kids.

IQ tests for adults are applicable to adults of ALL age ranges

Question 4

What is WPPSI?

Answer 4

Wechsler Preschool and Primary Scale of Intelligence

Used for children

Designed to test development of children 2.5 yrs to 7 yrs

ASSESES

1. Overall IQ
2. Verbal comprehension
3. Perceptual Reasoning
4. Memory
5. Processing Speed

QUESTIONS

Symmetry, object permanence.

Question 5

What is WISC?

Answer 5

Wechsler Intelligence Scale for Children

Designed to test intel of children ages 6-16

Provides similar metrics to WPPSI, but content questions re different

Perceptual and motor control development tends to end around 7 yrs of age. So many useful questions on the WPPSI become uninformative of development around the age of 7

QUESTIONS

How would you portray a picture of a stickman, or the corner of a room.

Question 6

What is WAIS?

Answer 6

Wechsler Adult Intelligence Scale

Similar to WPPSI, and WISC, but for adults

QUESTIONS

Which 3 partials combine to form the full picture?

Question 7

What is SAT?

Answer 7

Scholastic Aptitude Test

Is req by American students to get into US schools

Gauges Math, writing, and critical reasoning

To identify if students have necessary skills for university

Correlates with tests of general mental aptitude (g) at about r = 0.82

Question 8

What is GRE

Answer 8

Graduate Record Examination

Required for most graduate school programs

Measures quantitive, verbal, and analytic reasoning skills

GRE VALIDITY

GRE scores correlate w first-year performance at r = .35

And correlate with faculty performance at r = .40
