The document traces the history of psychological testing from its origins in China and Europe in the 1800s to its modern use today. It describes how early tests focused on measuring reaction time and sensory abilities but later shifted to measuring intelligence through tests developed by Binet and Simon. Widespread testing began during WWI when the Army used tests to classify recruits, leading to a boom in testing through the 1940s when tests were used to assess personality and vocational fit. However, testing was later criticized for biases against women and minorities and seen as invasive of privacy. While controversial, testing continues to be used widely in education to assess student and program performance.
10. He pioneered thestudy of individual
differences in mentalability.
Related intellectual ability to skills
suchasreaction time, sensitivityto
physicalstimuli, and body
proportions.
Demonstrated that objective tests
could be devised throughstandardized
procedures.

12. Cattell transported brass instruments to the
U.S.; did an elaborate reaction time studies;
invented the term mentaltest.
Some of his famous studentswere:
Thorndike (1898)
Woodworth (1899) and E.K. Strong (1911)whose
Vocational Interest Blank ,after somany revisions,
is still in wide use.

interests.

▪ Correlated mental tests and academic
performance which showed weak
relationship between reaction time and
sensory discrimination asmeasures of
intelligence.
▪ desirable development in the history of
psychologicaltesting; abandonment of RT
and sensorydiscrimination

70years later correlationwas
established and Stenberg
recognized the valueof RTin

21. 15-year boom period
New science ofPsychology was called
on to play apart in military situations
Yerkes used the Army Alpha(Verbal)
and Army Beta for selection of
individuals for militaryservice.
22. • Robert Yerkes,a Harvard psychology
professor. Convinced the Departmentof
War that it should test all of its 1.75
million recruits for intelligence tests, so
they could be classified and given
appropriate assignments (Goddard and
Terman also chaired thiscommittee).
23. The height of Goddard's successcame at atime when America
was experiencing alarge influx of immigrants from Europe. The
Immigration Restriction Act, passedin 1924 (which remained in
effect until 1965)wasinfluenced byAmerican eugenics'efforts. In
1913Goddard was invited to Ellis Island to help detect morons in
the immigrant population. In his Intelligence Classification of
Immigrants of Different Nationalities (1917)he asserted that most
of the Ellis Island immigrants were mentally deficient. For
example, he indicated that 83%of all Jewstested were feeble-
minded, aswere 80% of the Hungarians, 79%of the Italians, and
87%of the Russians.The result was that many immigrants were
turned away andsent back to Europe.

27. test developers and users
placed too much reliance on
the correctness of tests results
regarding people’s abilities
and characteristics
28. Goddard (1906) began testing378
residents and categorized themas
Idiot (ma below 2), imbecile (3-
7), feebleminded (8-12), moron
(foolish)
Goddard’s desire wasto separate
people out
29. Believed feeble minded people werethe
cause of most socialproblems
(thievery, laziness, alcoholism, prostitution, i
mmorality).
• Called for the colonization of “morons” to
restrict their breeding. Further
, hebelieved
that many immigrants were feebleminded.
30. • Produced evidence that supported
segregation. Sounded dire warningsthat
racial intermixture would inevitably
cause a deterioration ofAmerican
intelligence. Later recanted:“without
foundation” Probably the result of
cultural and languagedifferences.
31. “Age of Discrimination”–testing
revealed largescore
differences betweenWhite
Americans and minorities-
“feeble-minded”; started to
question the test and the
conclusionsdrawn from the tests
32. 1930s saw a crash in the
expectations of mental
measurement.
criticisms led young
Psychologist to initiate the
Mental Measurements
Yearbook (MMY) tocritically
review test.
33. Psychological measurementwas
used again for military service
where batteries of tests were
developed that measure several
abilities.
Reducedfailure rates and led to
emphasis on testbatteries.
34. 1950seducational and
psychological testing grew and
expanded not lonely in the field
of education but other fields like
business, industry,clinics.
APAset guidelines for good
testing practice.
37. despite criticisms ,governments
and specifically educational
institutions were puttinggreater
faith in testing to determine
whether government and
educational programs were
achieving theirobjectives.
39. Failures
▪ Segregation between/amongminorities.
▪ Created intellectualhierarchy between/among races.
▪ Labelling: Americans superior overAfricanAmericans
and otherminorities.
▪ Discrimination between men and women in
employment.
▪ Invasion of privacy
