Q

Describe the following aspects and elements of Charles Darwin’s work: his theory of evolution

A
  • struggle for survival (more offspring than environmental resources) results in survival of the fittest & natural selection.
  • natural selection –> nature allows those with characteristics most conducive to survival to reproduce
  • no direction/purpose for evolution
  • fitness + adaptive features
  • applied to earth & humans

Q

Describe Sir Francis Galton’s work and beliefs with respect to word association test

A
  • 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.

21
Q

What did Galton observe from word association test?

A

1) responses to stimulus words tended to be constant

2) responses were often drawn from childhood experiences.

3) procedure revealed aspects of the mind never revealed before.

22
Q

What did Galton’s work with word association anticipate?

A

two aspects of psychoanalysis; free association & unconscious motivation

23
Q

Describe Sir Francis Galton’s work and beliefs with respect to mental imagery,

A

asked people to imagine scene from when thay had breakfast

found that ability to image was normally distributed

24
Q

Describe Sir Francis Galton’s work and beliefs with respect to anthropometry

A
  • created anthropometric lab
  • measured head size, arm span, standing height, reaction time, lung capacity in 9000 humans
  • effort to measure intelligence
25
Q

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

A

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

26
Q

Karl Pearson

A

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

27
Q

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

A

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.

28
Q

Summarize James McKeen Cattell’s role in psychology.

A

founded the first lab designed for undergrad students in Pennsylvania.

used term mental test for first time in article

29
Q

Who is James McKeen Cattell?

A
  • Wundt’s first experimental assistant
30
Q

Describe Alfred Binet’s work in individual psychology

A

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.

31
Q

Describe Alfred Binet’s work in assessing deficiencies in intelligence

A

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.

32
Q

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

A

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.
33
Q

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

A
  • 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
34
Q

Intelligence quotient (IQ)

A

mental age divided by chronological age times 100.

  • Stern + Terman
35
Q

Describe Alfred Binet’s notion of mental orthopedics.

A

mental orthopedics are exercises used for growing ones’ intellect.

enhance determination, attention and disclipline

36
Q

Describe Alfred Binet’s legacy

A
  • said intellectual abilty isnt fully inherited –> notion of mental orthopedics
  • said poor test scores don’t always mean deficiencies.
37
Q

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

A
  • used factor analysis to investigate nature of intelligence
  • found 2 factors that can measure intelligence; specific factors and general intelligence
38
Q

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

A

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.

39
Q

Contrast Spearman and Binet’s views regarding the nature of intelligence.

A

Spearman
- emphasized unitary nature of intelligence.
- viewed intelligence as largely inherited.

Binet
- emphasized diversity of intelligence.
- viewed intelligence as modifiable by experience.
