Unit 3 - Chapter 10 - Evolution and Individual Differences Flashcards
Briefly describe the work of Jean Lamarck (1744–1829).
Inheritance of acquired characteristics
Briefly describe the life and work of Herbert Spencer
- introduced term intelligence into psychology
- coined term survival of the fittest
survival of the fittest
organisms with traits conducive to survival under the circumstances will live and reproduce.
Briefly describe the life and work of Herbert Spencer including his view of evolution
- evolutionary associationism = contiguity + voluntary behaviour
contiguity + voluntary behaviour explans why some behaviours perist.
evolutionary associationism
Briefly describe the life and work of Herbert Spencer including his view of social Darwinism.
social darwinism states that if given freedom to compete in society, the ablest individual will succeed and the weaker ones will fail.
Difference between Spencer and Darwin
To Spencer, evolution = progress, purposeful, mechanism by which perfection is approximated.
Darwin didnt believe this.
Describe the Spencer-Bain principle
probability of some behavior increases if it is followed by a pleasurable event and decreases if it is followed by a painful event.
Describe the following aspects and elements of Charles Darwin’s work: his voyage on the Beagle &
observed that tortoises, plants, insects, etc differed somewhat from island to island.
applied Malthus principle to animals, plants and humans.
Describe the following aspects and elements of Charles Darwin’s work: his theory of evolution
- 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
bility to survive and reproduce determined by organism’s environment and features
Fitness
Darwin - Evolution as Applied to Earth
conflict with the church over the age of the earth because he believed the process of evolution occurred over millions of years
Darwin - Evolution as Applied to Humans
- humans are product of evolution
- humans and great apes share distant ancestor
- human emotions are remnants of past animal emotions
- expression of emotions is culturally universal
Describe the following aspects and elements of Charles Darwin’s work: his influence on science and psychology.
- launched modern comparative & animal psych
- stimulated study of individual differences
- studying behaviour as important as studying mind
- gave birth to sociobiology/evolutionary psych
Sociobiology
modern extension to the explanation of human and non-human social behavior
- refered to as evolutionary psych.
- fitness refers to perputation of ones genes in sociobiology.
Sir Francis Galton
- mission in life = to measure and catalog individual differences.
- invented weather map
- suggested use for fingerprints for person ID
- studied composite portraiture
Describe Sir Francis Galton’s work and beliefs with respect to the measurement of intelligence
- know the world only through the senses.
- more acute senses = more intelligent.
- intelligence is inherited.
- high eminence is an accurate indicator of high intellectual ability.
Describe Sir Francis Galton’s work and beliefs with respect to eugenics
- eugenics is the improvement of living organisms through selective breeding.
- advocated for this
- said couples should be scientifically paired
Describe Sir Francis Galton’s work and beliefs with respect to nature versus nurture
- extreme nativist
- potential for high intelligence was inherited but must be nurtured by a proper environment.
- viewpoint supported by first use of questionnaire, and twin studies
