the functionalist protest
The Functionalist Protest
  • Functionalists’ Goal: Determine how the organism uses the mind to adapt to the environment
  • First uniquely American system of psychology
  • Deliberate protest against Wundt\'s and Titchener\'s systems
  • Interest in applying psychology to real world
the evolution revolution charles darwin 1809 1882
The Evolution Revolution: Charles Darwin (1809-1882)
  • On the Origin of Species by Means of Natural Selection (1859):one of the most influential books in the world
    • Form and substance of American psychology shaped by Darwin’s ideas
an ode to evolution
An Ode to Evolution
  • Organic life beneath the shoreless wavesWas born and nurs\'d in ocean\'s pearly caves;First forms minute, unseen by spheric glass,Move on the mud, or pierce the watery mass;These, as successive generations bloom,New powers acquire and larger limbs assume;Whence countless groups of vegetation spring,And breathing realms of fin and feet and wing.
    • Erasmus Darwin. The Temple of Nature. 1802.
other predecessors
Other Predecessors
  • Jean-Baptiste Lamarck (1809): Active Modification
    • Through efforts to adapt to environment
    • Inherited by succeeding generations
  • Vestiges of Creation (1844) by Anonymous
other predecessors1
Other Predecessors
  • Darwin Read Thomas Malthus, Essay on the Principle of Population (1789)
    • Food supply increases linearly
    • Human population increases exponetially
    • Result: Starvation is an inevitable part of a cycle
    • Only the most aggressive, intelligent and flexible will survive
    • Social welfare is bad for the Britain
setting the stage 19 th century britain
Setting the Stage – 19th century Britain
  • Zeitgeist
    • Receptive intellectual climate
    • Social evolution due to industrial revolution
    • Growing dominance of science – it was working!
the world comes to europe1
The World comes to Europe
  • Fossils and bones of extinct species found
HMS Beagle: 1831-1836
  • Captain Fitzroy was looking for a creationist!
  • Darwin makes Geological and Zoological observations that challenge Biblical notions.

Galapagos Finches

Peter and Rosemary Grant: visited islands in 1973 to observe modifications in several generations of 13 finch species – Changes occur faster than Darwin predicted!

darwin finally goes public
Darwin Finally Goes Public
  • Worked on his theory of evolution for 22 years
  • A. R. Wallace (1858) wrote Darwin about a theory of evolution that he developed in 3 days!
  • Ethical dilemma for Darwin
  • Darwin overwhelmed with new physical illness
Spontaneous variability among members of a species is inheritable – He described genes and mutations without the benefit of biochemistry!
  • Natural selection: process that leads to survival of organisms which adapt to the environment; Elimination of those which do not
thomas henry huxley 1825 1895 and the evolution controversy
Thomas Henry Huxley (1825-1895) and the Evolution Controversy
  • Striving biologist; Leader among England\'s scientists
  • Champion of Darwin’s theory
  • 1860: Debate on theory of evolution at Oxford: Huxley versus bishop Samuel Wilberforce who defended the Bible and Robert Fitzroy, captain of HMS Beagle

Thomas Henry Huxley (1825-1895) and the Evolution Controversy
  • 1865 Fitzroy Commits suicide
  • Wilberforce dies
  • 1925: Scopes Monkey Trial
  • 1987: Louisiana “Equal Time” case
  • 1999: Kansas State BOE
  • 2004: Dover, PA
the genie is out of the bottle
The Genie is out of the Bottle
  • The white supremacy movement
  • Social and Economic Darwinism

The Genie is out of the Bottle
  • Darwin’s other work
    • 1871: The Descent of Man
      • Emphasized similarity between animal and human processes
    • 1872: The Expression of the Emotions in Man and Animals
    • 1877: A Biographical Sketch of an Infant
the evolution of machines
The Evolution of Machines

Samuel Butler (1835-1902)

  • Machines would become self-acting
  • Capable of simulating human intelligence
  • Humans become dependent on machines
  • Suggested machines would become superior
darwin and psychology
Darwin and Psychology
  • Subject matter of psychology goes from elements to functions of consciousness
  • Continuity in mental functioning between humans and lower animals/humans and ancestors
  • Studying animal behavior can help us understand human behavior
  • How does the brain function and adapt?
  • Methods were broadened in scope
  • Increased focus on individual differences and their measurement – no trait is accidental!!
individual differences francis galton 1822 1911
Individual Differences: Francis Galton (1822-1911)
  • Darwin emphasized differences within species – including humans!
  • Had been examined by Weber, Fechner, Helmhotz but ultimately considered inappropriate by the early German schools
  • Galton – Darwin’s cousin mixed evolution with statistics
francis galton 1822 1911
Francis Galton (1822-1911)
  • “I have no patience with the hypothesis occasionally expressed, and often implied, especially in tales written to teach children to be good, that babies are born pretty much alike, and that the sole agencies in creating differences between boy and boy, and man and man, are steady application and moral effort.”
galton s work
Galton’s Work
  • Mental Inheritance
    • HereditaryGenius (1869)
      • Eminent men have eminent sons
      • Specific forms of genius inherited
      • Founded eugenics: improve inherited human traits through artificial selection
      • Applied statistical concepts to heredity problems
      • Eminence not a function of opportunity
galton s work1
Galton’s Work
  • 1874: English Men of Science
  • 1889: Natural Inheritance
  • Established eugenics laboratory at university college, London
  • 1904: founded organization for promoting racial improvement
  • Clearly opposed the British Empirical movement of the 17th century
statistical methods and differential psychology
Statistical Methods and “Differential Psychology”
  • Galton assumed statistical techniques of Biology could be applied to mental characteristics. In doing so, developed:
    • Mean and standard deviation
    • Correlation Measures
      • His student, Pearson, developed product-moment coefficient of correlation
    • Pearson’s r: for Galton’s discovery of regression toward the mean
why galton
Why Galton?
  • Mental Tests (coined by J.M. Cattell)
  • Intelligence and sensory capacities
galton s passtimes
Galton’s Passtimes
  • “Arithmetic by Smell” and other topics
    • Self-induced paranoia
    • Validity of religious beliefs
    • Power of prayer
    • Yawns and coughs as a measure of boredom
    • Arithmetic by Smell
animal psychology and the development of functionalism
Animal Psychology and the development of Functionalism
  • Before Darwin: animals were automata
  • With Darwin’s The Expression of the Emotions in Man and Animals…
    • Continuity between humans and animals
    • Search for evidence of intelligence in animals
    • Human emotional behavior: inheritance of behavior once useful to animals
foundations of functionalism
Foundations of Functionalism
  • Darwin’s Legacy for Psychology
    • Regard each anatomical structure, including the brain, as a utilitarian element in a total living adaptive system
  • Indirect Legacy
    • Galton and measurement
    • Comparative Psychology
    • Lloyd Morgan inspires Behaviorism
