Self-Fulfilling Prophecy?
  • Clever Hans the Horse
  • Experimenter Expectancy Effect– The experimenter’s results are altered by expectations.
  • 1963 rat study– students assigned “smart” rats reported faster maze times than “dull” rats
  • These results threaten all previous studies
  • Rosenthal wondered how this effected various environments, such as schools.
theoretical propositions
Theoretical Propositions
  • Labeled as Pygmalion Effect
  • Teachers, when given IQ scores of students, will treat students differently based on their scores
  • This will affect the students’ performances
  • Used Oak School– lower middle-class in large town
method
Method
  • Kids grades 1-6 given IQ test
  • Called a “Harvard Test”– predictor for academic “bloom and growth”
  • 3 classes/grade level
  • Teachers were given the list of those who scored in the top 20% on the Harvard Test
  • This list was actually assigned at random
  • At the end of the year the children were given the same IQ test
results
Results
  • The children with the expectation of greater intellectual ability had greater improvement on the test
  • The evidence of the Pygmalion effect decreased as age increased
    • -More easily influenced

-Already have known standards

-Difference between teachers for younger and older grades

significance
Significance
  • Effects of teachers’ expectations
  • Accuracy of IQ tests
  • Study in 1974: Teachers told random students were “bright”
    • -Smiled more
    • -Eye contact
    • -Favorable reactions
    • -Students enjoy school more
  • What if IQ tests are inaccurate? If all teachers bias based on these tests?
  • Similar results were shown based on race, gender, and other categories instead of IQ
