Answer 20

• first word association test in psych
• made 3 important observations (constant responses, drawn from childhood, revealed hidden aspects of the mind).

Test
- wrote 75 words on sheets of paper
- glanced at each word and noted his response to it on another sheet of paper
- did this four times, randomizing the words each time.

• effort to measure intelligence

Question 25

Describe Sir Francis Galton’s work and beliefs with respect to statistical correlation (as well as regression toward the mean)

Answer 25

correlation --> systematic variation between two variables. regression toward the mean --> tendency for extremes to become less extreme in offspring. scatterplots --> visually determine the strength of a relationship introduced median bc less influenced to extreme scores

Question 26

Karl Pearson

Answer 26

coefficient of correlation (r) --> formula that produced a mathematical expression of the strength of a relationship

Question 27

Describe Sir Francis Galton’s work and beliefs with respect to his contributions to psychology.

Answer 27

First to study nature-nurture question, the use of questionnaires, the use of word association test, the study of imagery, intelligence testing, and development of correlational technique.

founded the first lab designed for undergrad students in Pennsylvania. used term mental test for first time in article

Question 29

Who is James McKeen Cattell?

Answer 29

- Wundt’s first experimental assistant

Question 30

Describe Alfred Binet’s work in individual psychology

Answer 30

examine the differences between one person to another. study cognitive abilities directly instead of indirectly via sensory acuity. differences are complex, higher order processes that vary according to age. low inter-correlation between his tests.

Question 31

Describe Alfred Binet’s work in assessing deficiencies in intelligence

Answer 31

tests to distinguish between children with mental deficiencies and children without them; 1) isolate one group of normal children, and another group of subnormal children. 2) test both groups to discover measurements that would consistently distinguish members of one group from the other.

Question 32

Describe Alfred Binet’s work in developing the 1905 Binet-Simon scale of intelligence

Answer 32

original version; - way of distinguishing between normal children and children with mental deficiencies. - included 30 mini-tests, with each test passed, the tests would become more difficult. - medium deficient children could often pass most of the tests, highly deficient children only passed a small number of the tests.

Question 33

Describe Alfred Binet’s role in developing the intelligence quotient (IQ)

Answer 33

- opposed the use of IQ - believed intelligence couldnt be represented by a simple number/term - Stern used results of Binet-Simon test to determine concept of mental age

Question 34

Intelligence quotient (IQ)

Answer 34

mental age divided by chronological age times 100. - Stern + Terman

Question 35

Describe Alfred Binet’s notion of mental orthopedics.

Answer 35

mental orthopedics are exercises used for growing ones' intellect. enhance determination, attention and disclipline

Question 36

Describe Alfred Binet’s legacy

Answer 36

- said intellectual abilty isnt fully inherited --> notion of mental orthopedics - said poor test scores don't always mean deficiencies.

Question 37

Briefly describe the life and work of Charles Spearman including his work in factor analysis

Answer 37

- used factor analysis to investigate nature of intelligence - found 2 factors that can measure intelligence; specific factors and general intelligence

Question 38

Briefly describe the life and work of Charles Spearman and his two-factor theory of intelligence.

Answer 38

specific factors --> individuals differ in their competence in such things as math, language, and music, etc. general intelligence --> overriding kind of intelligence, determined almost exclusively by inheritance.

Question 39
